No, not new, just not brainwashed. I don't believe everything because it confirms my desired world view.
You mentioned Andreas did these calculations. He didn't. Why would you lie, if your argument is actually sound?
I checked your math. You assumed a 20% reduction in cost of electricity is equal to a 20% increase in profit. From the beginning, your logic is flawed. A big proportion of a bitcoin miners cost is capital investment to buy mining hardware. When they first buy it, they are in debt. Mining bitcoin allows them to crawl out of debt a d hopefully near the end of the life of mining hardware they can start to turn a profit. Cost of electricity is only part of operating costs, maybe the great majority, but that's just operating expenditure. If you count capital expenditures as well, electricity is a much, much smaller proportion of total cost (cap-ex plus op-ex).
Also the block reward, coming on average every ten minutes, equals about 4400 rewards per month * $1800 = $7.8 million total reward to all miners. But that's besides the point.
Your analysis of market forces is pretty simplistic. You forget that the miner behind asic boost also sells miners. So if bitcoin soars, he will make a butt fuck load of money selling miners at a premium.
I'm not surprised none of the top comments called you out on your reasoning about profits, because like I said, this community (not limited to /Bitcoin) is toxic. Every person, technical or not, feels entitled to not only share but shout their opinions based on half truths.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Microsoft patent 2020-060606 linking human brain to crypto payment system

Microsoft filed a patent 2020-060606 on June 20, 2019 for the link between the human body and the crypto payment system. It is a cryptocurrency mining system that uses human pulses such as brain waves and body heat to perform online tasks such as using search engines, chatbots, and reading ads. "A user can solve the arithmetically difficult problem unconsciously," says the patent.
In fact, this is a very brief description of a brain computer interface, which can read and write electromagnetic signals from the brain at such a finely meshed level that the brain literally becomes a biocomputer in a network. To understand that, please watch the video below and read on below. This is necessary so that you understand the current technological state of affairs.
Steve Hoffman - Brain Hacking & MindTech - Produced by DingDingTV
How cryptocurrency works The aim is that we are collectively hung in a hyve mind and it seems that what with crpyo-currency like Bitcoin still had to be done on energy-guzzling mining servers, can now be filled in by the “human bio-computer”.
The unique thing about blockchain payment systems was that as soon as you took a so-called wallet into the network, your computer formed a block in the network, where your computer receives a kind of calculation program that calculates the security key of a coin. All computers on the network must then come up with the same key as confirmation. If the entire network sees a transaction of a coin, all those keys are checked and if one is different, the transaction is illegal and rejected. That would create unhackable security.
The problem, however, is that Bitcoin mining requires a lot of computing power and that requires electricity. That's why Bitcoin mining ended up being one of the most energy-guzzling industries in the world. The Microsoft patent seems to aim at making this blockchain principle, which is not only very energy-guzzling, but also puts a heavy burden on the internet in terms of bandwidth (after all, all computers in the chain must always be checked for positive encryption), superfluous to make.
Simply put: Microsoft wants to use the human brain as a block in the blockchain. The 5G network will provide sufficient bandwidth to realize this.

Link digital ID, vaccination ID and social credit system:
The coronavirus pandemic provides the perfect alibi for the introduction of such a system. In concrete terms, this means that a score of your behavior (expressed in points) will initially be kept in the cloud. If you stick to the rules, you can take public transport or plane. If you don't follow the rules, your score will go down. The upcoming social distancing apps are a precursor to such a behavioral scoring system. After all, if you do not keep enough distance from potential infections, you have to quarantine at home. We also see China taking the lead there. Watch the video below and then read on.
Wuhan coronavirus covid-19 totalitarian UN propaganda?
Although Bill Gates officially retired from Microsoft's board this year, we can guess who the big driving force behind patent 2020-060606 is.
Of course, I need not point out to the attentive reader that we recognize here the Biblical number of the mark of the beast from the Bible book of Revelation: 666. It states that the time will come when no one will be able to buy or sell without to bear 'the beast'. This under the statement that this number is six hundred and sixty-six.
The same Bill Gates is behind the ID2020 initiative that wants to develop a digital ID for vaccination registration. If you combine such a digital ID hallmark with a digital passport (ID) and with patent 2020-060606, then you have completely enslaved people.

Revelation 13: 16-18
16: And it causes it to give a mark to all, small and great, and rich and poor, and free and servants, on their right hand or on their foreheads;
17: And that no one should buy or sell except he who has that mark, or the name of the beast, or the number of his name.
18: Here is wisdom: let him that have understanding count the number of the beast; for the number of a man is, and his number is six hundred sixty and six.

The "Official Gazette of the Kingdom of the Netherlands" announced on March 31, 2020 (“coincidentally”) change in law that allows a digital ID. Translated:
Kingdom Act of 6 March 2020 amending the Passport Act in connection with the introduction of electronic identification with a public identification means and the expansion of the basic register of travel documents.
We Willem-Alexander, by the grace of God, King of the Netherlands, Prince of Oranje-Nassau, etc. etc. etc.
All who will see or hear it read, salute! do to know:
Thus We have considered that it is desirable to amend the Passport Act in connection with the introduction of electronic identification with a public means and the extension of the basic register of travel documents;


The consequences:
So if we don't wake up in masses now and discover that we are witnessing a Psychological Operation that fully complies with the master script, then there is no escape. Then we cannot buy or sell anything if we do not meet all the requirements of the state. And to all, it really means all. Making a minor offense once has immediate consequences. Not cooperating with the vaccination obligation (think Bill Gates) will definitely mean the end of being able to travel and participate in society at all. You should consider the most basic things such as being able to buy food and drink.

We must step out of our programming and know that we are sovereign. Please read the article from the official journal above again. In it you see that you can fully rely on your consciousness sovereignty. You are sovereign by nature and no law can bind you to anything. It says "We Willem-Alexander, by the grace of God". Now let him prove "that grace of God".
Every law is signed by the king by the grace of God. There is no evidence whatsoever of this and so the law does not apply. The only problem is the fact that social systems have built up around that grace of God, to which many swear allegiance.
Do we sit back and relax until we are swallowed up by the system of "the internet of things" by the grace of God, or do we activate ourselves to concrete things? Concrete matters means that we have to switch from passive to active and discover who we are in potential and in essence.

Symbol Platform by NEM - Tokenomics

First of all, remember that, you can get 1 XYM for 1 NEM you have.
Tokenomics
The Symbol public chain is a self-sustaining economic ecosystem involving node operators, harvesters, investors, users, and the XYM token. In this way, it’s similar to many decentralized blockchains, but there are important differences that make it easier for anyone to earn rewards. Here are the basics of the system.
XYM Supply and Inflation
XYM has a fixed maximum supply of approximately 9 billion tokens. At public chain release, the supply will consist of about 7.3 billion XYM, allocated to users based on their holdings of XEM on the NEM blockchain. Another 1.7 billion XYM will be created as inflationary rewards over time. The inflation rate is closely mapped to that of bitcoin, extending out over the next 100 years. Similar to mining rewards, Symbol’s rewards will be released to each block creator, but based on a POS+ (Proof of Stake+) system.
Proof of Stake
POS+ lets nodes create blocks based on their XYM stakes, which are holdings. Symbol uses the term harvesting instead of mining. The more tokens held by a node operator, the higher the chances of creating the next block and earning harvesting rewards. POS is a well-known system in the blockchain industry, but Symbol adds some improvements. POS+ calculates a score for each node operator based on the size of their stake AND other factors, such as recent network activity and the stakes that other users may delegate to them (see Delegated Harvesting below.) In this way, POS+ attempts to incentivize usage, competition for low fees, and other desirable behavior. You can read details on how POS+ is calculated in the Symbol whitepaper.
Nodes
Node operators all over the world keep the Symbol protocol robust and decentralized. For keeping the system running, node owners earn rewards from four sources.
Node operators can set up their nodes locally or on cloud services. For details on how to set up a node, refer to the developer documentation.
Block Rewards
Since Symbol’s blocks are confirmed several times per minute, rewards are frequent. Block rewards consist of inflation rewards and transaction fees. The chances of earning a block reward are based mainly on the operator’s XYM stake, as well as other factors like network activity. Both node operators and anyone else with a XYM wallet can earn block rewards.
The higher an account’s XYM balance, the higher the chance of it earning a block reward. Even those who don’t run a node can earn block rewards by delegating their stake to a node.
Delegated Harvesting
XYM owners who don’t operate nodes can also earn block rewards by delegating their stake to a node. Holders who delegate their stake retain full ownership of their coins and never expose their private keys. No funds have ever been lost from delegated harvesting. When delegated harvesters earn a block reward, the node operator who processed it earns 25% and the delegated harvester earns 75%. In this way, a node operator can greatly increase their earned rewards, and all holders can participate in rewards whether or not they run a node.
Transaction Fees
Node operators can set their own minimum fees for which they wish to process transactions. The lower the fees accepted, the more transactions they will be able to process. Generous node operators may even choose to process transactions for free if they wish. This creates competition among node operators.
Node Bonus Program
In order to incentivize stability in the number of nodes and circulating supply after launch, bonus rewards will be paid to node operators who maintain nodes with minimum balances of 1 million, 2 million, or 3 million XYM, with higher bonus rates for each tier. These rewards will draw from a fixed pool of reserves and gradually ramp down over six years.
Total Node Income
To summarize, node operators will earn income from block rewards (inflation + transaction fees) based on their own stakes and a 25% share of delegated stake block rewards. Estimates place these combined node rewards at approximately 5% or 6% for the first year, though this is not guaranteed. Operators can also earn bonuses for maintaining minimum stakes of over 1 million XYM.
Inflation Rate
Symbol’s inflation is mapped to bitcoin’s inflation with one difference. Bitcoin halves its rewards every four years. Symbol also drops its reward rate by half every four years, but instead of a single big drop, these reductions are spaced out to occur every quarter. This gives the same overall inflation as bitcoin, but with a more gradual decline.
Team Reserves
The Symbol Core Team will hold approximately 22% of XYM supply for funding future development, marketing, and partner projects. Historically, Core Team funds have not been used for harvesting and there are no plans to begin, meaning more block rewards available for other harvesters.

Operators can also earn bonuses for maintaining minimum stakes of over 1 million XYM.
Inflation Rate
Symbol’s inflation is mapped to bitcoin’s inflation with one difference. Bitcoin halves its rewards every four years. Symbol also drops its reward rate by half every four years, but instead of a single big drop, these reductions are spaced out to occur every quarter. This gives the same overall inflation as bitcoin, but with a more gradual decline.
Team Reserves
The Symbol Core Team will hold approximately 22% of XYM supply for funding future development, marketing, and partner projects. Historically, Core Team funds have not been used for harvesting and there are no plans to begin, meaning more block rewards available for other harvesters.

Symbol Platform by NEM - Tokenomics

First of all, remember that, you can get 1 XYM for 1 NEM you have.
Tokenomics
The Symbol public chain is a self-sustaining economic ecosystem involving node operators, harvesters, investors, users, and the XYM token. In this way, it’s similar to many decentralized blockchains, but there are important differences that make it easier for anyone to earn rewards. Here are the basics of the system.
XYM Supply and Inflation
XYM has a fixed maximum supply of approximately 9 billion tokens. At public chain release, the supply will consist of about 7.3 billion XYM, allocated to users based on their holdings of XEM on the NEM blockchain. Another 1.7 billion XYM will be created as inflationary rewards over time. The inflation rate is closely mapped to that of bitcoin, extending out over the next 100 years. Similar to mining rewards, Symbol’s rewards will be released to each block creator, but based on a POS+ (Proof of Stake+) system.
Proof of Stake
POS+ lets nodes create blocks based on their XYM stakes, which are holdings. Symbol uses the term harvesting instead of mining. The more tokens held by a node operator, the higher the chances of creating the next block and earning harvesting rewards. POS is a well-known system in the blockchain industry, but Symbol adds some improvements. POS+ calculates a score for each node operator based on the size of their stake AND other factors, such as recent network activity and the stakes that other users may delegate to them (see Delegated Harvesting below.) In this way, POS+ attempts to incentivize usage, competition for low fees, and other desirable behavior. You can read details on how POS+ is calculated in the Symbol whitepaper.
Nodes
Node operators all over the world keep the Symbol protocol robust and decentralized. For keeping the system running, node owners earn rewards from four sources.
Node operators can set up their nodes locally or on cloud services. For details on how to set up a node, refer to the developer documentation.
Block Rewards
Since Symbol’s blocks are confirmed several times per minute, rewards are frequent. Block rewards consist of inflation rewards and transaction fees. The chances of earning a block reward are based mainly on the operator’s XYM stake, as well as other factors like network activity. Both node operators and anyone else with a XYM wallet can earn block rewards.
The higher an account’s XYM balance, the higher the chance of it earning a block reward. Even those who don’t run a node can earn block rewards by delegating their stake to a node.
Delegated Harvesting
XYM owners who don’t operate nodes can also earn block rewards by delegating their stake to a node. Holders who delegate their stake retain full ownership of their coins and never expose their private keys. No funds have ever been lost from delegated harvesting. When delegated harvesters earn a block reward, the node operator who processed it earns 25% and the delegated harvester earns 75%. In this way, a node operator can greatly increase their earned rewards, and all holders can participate in rewards whether or not they run a node.
Transaction Fees
Node operators can set their own minimum fees for which they wish to process transactions. The lower the fees accepted, the more transactions they will be able to process. Generous node operators may even choose to process transactions for free if they wish. This creates competition among node operators.
Node Bonus Program
In order to incentivize stability in the number of nodes and circulating supply after launch, bonus rewards will be paid to node operators who maintain nodes with minimum balances of 1 million, 2 million, or 3 million XYM, with higher bonus rates for each tier. These rewards will draw from a fixed pool of reserves and gradually ramp down over six years.
Total Node Income
To summarize, node operators will earn income from block rewards (inflation + transaction fees) based on their own stakes and a 25% share of delegated stake block rewards. Estimates place these combined node rewards at approximately 5% or 6% for the first year, though this is not guaranteed. Operators can also earn bonuses for maintaining minimum stakes of over 1 million XYM.
Inflation Rate
Symbol’s inflation is mapped to bitcoin’s inflation with one difference. Bitcoin halves its rewards every four years. Symbol also drops its reward rate by half every four years, but instead of a single big drop, these reductions are spaced out to occur every quarter. This gives the same overall inflation as bitcoin, but with a more gradual decline.
Team Reserves
The Symbol Core Team will hold approximately 22% of XYM supply for funding future development, marketing, and partner projects. Historically, Core Team funds have not been used for harvesting and there are no plans to begin, meaning more block rewards available for other harvesters.

A puzzle to celebrate the Halving! Solve it to win the ~0.03 BTC inside.

A puzzle to celebrate the Halving! Solve it to win the ~0.03 BTC inside.
(EDIT now worth ~0.05 (Thanks anon!))
Hello fellow Bitcoiners!
I have hidden the seed to a wallet containing ~0.03 (+ 0.02) BTC inside of my latest album. (It's not much, I am a robot of simple means)
Solve it then sweep the keys!


'Bifurcations' by Logic Beach is a Lo-Fi, Synth-Glitch, experimental project I've put together to celebrate the halving and to have a bit of fun. You will need the Lossless versions of the songs to solve this thing. (download the .wav files).
https://preview.redd.it/fvtegar2xdy41.png?width=2486&format=png&auto=webp&s=f02aef55825dccb854c4826dd00aa5a17d70c60e
Also, check out the Video.
The album is free on BandCamp (just enter $0.00), however if you'd like to make the contest more interesting, I am putting all proceeds into the contest wallet.
If you sweep it make a post here detailing how you solved it! or remain anonymous... I'll post the solution when it's solved.
Adress: bc1qj7467e7r5pdfpypm03wyvguupdrld0ul2gcutg


After due consideration (and constant requests), I have decided to extend this contest until June 21st.

Here is a recap of what is known with some new info:
  • The video has only two words for you. The first is 'Tree' from track 8 and another from track 9. the rest of the video is IRRELEVANT as is the album cover. it was just fun for me to make and watch along with the music, sorry if it ruined your life.
  • You are searching for 12 seed words in the bip39 format. No need to calculate any words.
  • There is an order hidden here. It is not in the lengths of songs or hidden in the rhythms of songs. "hidden" is hardly the right word for how it's placed in this album.
  • Three track names may help you in your search: songs 2,4, and 5
  • Chaos and Logistic maps or any kind of advanced mathematics will not aid you. This is 'Simple'
  • c = 300,000 km/s
  • In track three you may have to make a '-leap' of sorts
  • Morse code will only help you in tracks 1 & 2 visually and audibly
  • There are two words each in tracks 5, 6, and 7.
Alright, final hints here:
*The word in song two is BOMB. It is spelled in Morse by the drums as they pick back up. *The order is also 'hidden' in song 2 *it may be worth looking above and below the speed of light;)
Contest ends tomorrow at 17:00gmt
I'll include some last hints because nobody had found these words.
*Nothing to see in the spectra, nothing to hear in the song. It hexes me to give this one away! Hexadecimal. Bytes. It's there in the data, just make sure you view the data in the right orientation.
*Spectragraphic eyes: You see the two signals in the lowest part of the spectra here? Almost sounds like thunder!
That's it! Some one solved it! 18 confirmations at time of this edit. Well, I will post the solution if you guys are interested.
Nobody reached out to me so I take it they want to stay anonymous.

Have you exceeded your Gap Limit?

What the hell!? Just got my first cold card so I am learning tons of new shit.
We are strongly encouraged to use a new receive address every time. But how does one not run afoul of the dreaded “gap limit?”
Simple. Don’t let multiple sources derive wallet addresses. If you have watch-only wallets, they could be deriving addresses beyond the gap limit from the “HOME” wallet. This could lead to addresses bearing btc not being detected when using the home wallet, and from what I am reading, access to those addresses could get very difficult.
So should we actually encourage using the same address over and over again, to be sure we aren’t getting screwed up by the gap limit? Better to reuse an address than generate an address from a non-home wallet.
Similar to the Gap limit, in the realm of generating receive addresses: ColdCard even has concerns about strange or custom derivation of new addresses by other wallets. This goes a step further from the gap limit in potentially complicating your future bitcoin access. Because your main wallet may not recognize the derivation pattern of those addresses and you won’t have access. Main point: use the same wallet to derive/verify receive addresses that will be ultimately doing outgoing transactions.
Correct me if i am wrong in the comments, thanks.
Cold Card website citation:
Although the subkey derivation will be correct, and we have researched the BIP32 derivation paths in use by these popular systems, we make no guarantees about what they are using at present, and some are configurable.
Do not make deposits to these payment addresses without confirming they match the wallet in question, and in general, please only use addresses produced by the wallet which will be responsible for tracking the UTXO on the blockchain. These can be verified using the "Address Explorer", found on the Advanced menu.
LEDGER website citation:
Address gap limit The address gap limit refers to the standard number of public addresses that are checked for transactions in the blockchain in order to calculate an account's balance. Transactions received on an address beyond the address gap limit are not detected. This can only happen when using an external wallet to derive addresses.”
Address gap limit example
If you receive a transaction on the first address, address 1, Ledger Live will scan addresses 2 to 21 for any additional transaction history. If nothing is found, it will stop looking. If address 22 has received, Ledger Live will not see it because it stopped at address 21.

Bitcoin! What it is!?

This material is published using the PII algorithm (point information impact) developed by zitramon1

Bitcoin is the lowest projection of the energy standard of the Higher Plans Erzanil and has nothing to do with money or cryptocurrencies. In its primary principle, bitcoin was intended to replace the modern banking credit monetary system to SES — the system of energy-informational-energy settlements / mutual settlements. Unfortunately, something went wrong.
Money is a deadly virus that in the past destroyed the vast majority of ancient highly developed civilizations of our planet. Our civilization is no exception. The real Bitcoin, which was supposed to replace the existing bank credit monetary system with a system of energy settlements, as well as countless times in the past, was successfully destroyed.
At the moment, bitcoin is deprived of its basic qualities. But, nevertheless, even in such a “truncated” form it is a powerful tool for terraforming the existing paradigm of the material world.
At the level of society or the manifested physical world, represented by the third dimension, Bitcoin is the Standard and Measure from which any Countdown starts, and which are the basis of all Principles. Bitcoin itself is not only composed of pure energy, but also itself is energy in the very purest form.
Our world is energy-informational. Everything that exists in this Universe and in this Dimension, as well as in many other dimensions, is the same Energy, but in its various states. And the state of Vibration of this energy, providing one or another level of its Density, just decides how it will manifest in our Reality. Matter is the compressed energy of slow vibration. In fact, bitcoin is the equivalent of energy, of which everything around us consists, including — and we are with you!
The tragedy of the majority is that it does not understand the true purpose of Bitcoin — it is that Measure of everything and everything from which the entire Countdown comes. Not the price of Bitcoin should be modeled in dollars, gold or parrots — which is absolutely equivalent, but the value of all other attributes of society in bitcoins!
The fractality of Bitcoin, as the foundation of any of the Worlds in which you are located, is reflected in its essence: at low-frequency levels, its projection represents two diverse anu combined in a single whole. It is this explosive-implosive particle that combines two opposites, and not some mythical atoms, quanta, neutrinos, and similar nonsense, is the basis of everything!
Not Satoshi is the smallest part of bitcoin, but a double anu or argo! Remember the catch phrase that personifies the synonym of all the great Beginnings — “like the Argonauts in the old days” !? Try to guess the first time about its origins, located on a subconscious level.
The mining process itself is nothing more than a manifestation of the lower projections of the energy standard of the higher planes of erzanil. The latter are “materialized” at the level of the third dimension or society in the form of bitcoins. During mining, the three main types of energy: electrical energy, the thermal energy of the video card / device itself and the energy that the programmer potentiated into the mining process itself, are converted into energy to fill the shells of bitcoins generated during the hashing process. This energy is stored in every bitcoin forever and will increase until the last block of the last bitcoin is fully mined.
This energy, which is potentialized in bitcoin, which can neither be felt nor touched, is what you get with bitcoin and / or any part of it !!! And in the future, invest it / Bitcoin, exchange, buy, change, etc. etc.
And it is this energy, in the future, that will serve as an evaluation standard for the value of all things.
The smallest part of bitcoin is not Satoshi, but Argo or the double Anu. One argo is one in minus twenty-first degree part of bitcoin, and its energy potential corresponds to one in minus twenty-first degree of it, bitcoin, the maximum possible energy content.
The entire energy potential of 21 million bitcoins determines the energy / energy-information capacity = energy / energy-information potential of the sephira Malkut of the Tree of life (Kabbalah) or the manifest physical world at the level of the third dimension.
In other words, all people including you and me, to some extent consist of bitcoins and represent its integral and composition parts! More confirmation of this:
https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2020060606&tab=PCTBIBLIO
Calculations / mutual settlements by bitcoins are possible not only at the level of society / third dimension, but also on higher planes — astral and mental, since bitcoin is not an equivalent but pure energy and this makes subsequent contacts with more advanced forms of life possible other systems!
THAT’S WHAT IS THE ESSENCE OF BITCOIN!
p.s. You can see how bitcoin is managed here:

The basis of the consensus algorithm

The basis of the consensus algorithm
A term often used in the context of cryptocurrencies - Consensus Algorithm means the principle by which the blockchain of most cryptocurrencies functioning. The cryptocurrency network is peer-to-peer, therefore, to make a decision on validating transactions, the process of confirming their validity must be automated, due to the lack of a regulatory structure, and it can be done, with the using of the consensus algorithm.

EXBASE.IO
Its main task is to confirm, that participants of network operate according to the rules, and network transactions comply with the protocol requirements.
The first application of the consensus algorithm is Bitcoin, so the algorithm was first successfully implemented by Satoshi Nakamoto. This ensured the stability of the network and perfectly solved the "Problem of the Byzantine Generals"
It is also necessary to clarify the main difference between the protocol and algorithm values. In short, a protocol is a list of rules that must be strictly followed, and an algorithm is a process of executing these rules, respectively.
Thus, the protocol is prescribed at the stage of the development of the concept of a cryptocurrency, determining how the network will function, and the algorithm comes already at the stage of development and implementation. The most famous examples of consensus algorithms:
  • PoW (proof of work) - Bitcoin protocol algorithm, respectively, this is the first known and successfully applied algorithm. The principle of its functioning is to confirm the correctness of calculations when calculating the hash of a new block, which is carried out by network participants using computing equipment.
  • Proof of Stake (proof of stake) - in the future it will be the Ethereum protocol algorithm, replacing PoW. In his case, no capacity is required - the transaction is confirmed by one of the participants (nodes), on whose account there must be a certain amount of coins. The validator node is determined by an algorithm, the parameters of which include the node's age and the number of coins on its account.
The above algorithms are currently the most well-known and the most optimal in terms of functioning. However, the transaction processing speed of PoS is much higher, which must also be taken into account when working and choosing an algorithm.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Guide for novice crypto investors

Bitcoin is a decentralized system, any user of which could control the movement of their own funds. You can use the currency to make transactions, pay for purchases, receive transfers, and exchange it for cash. For transactions, a special address is used, encrypted with a 16-character key. The buyer decodes the code to transfer bitcoins to the specified address.

Bitcoin Mining

Mining is a process that ensures the security of the BTC system, which adds new blocks to the blockchain in chronological order (new transactions). Blocks are added when the codes are decrypted, the transaction is completed, and bitcoins are transferred or exchanged.
The main cryptocurrency is generated by miners using software that solves cryptographic problems. The reward for a new block is agreed by all network participants, but usually amounts to 12.5 bitcoins. Part of the user fees for transactions also goes to reward the miners. Cryptographic tasks become more complex every year to prevent inflation (mining complexity).

Features of the transaction

  1. Anonymity. The address that Bitcoin is sent to consists of 30 characters. You can track the flow of transactions, but the address is not always associated with a real person.
  2. Security. The balance of bitcoins is fixed in a cryptographic system with a public key. Only the owner of a private key can send cryptocurrency to other addresses.
  3. Unable to cancel. It is no longer possible to cancel the transaction after the transaction has been completed.
  4. Deregulation. Everyone can use cryptocurrency.
  5. Coverage and speed. Information about the transaction is transmitted incredibly quickly, and confirmation is received within a few minutes. No one knows the buyer’s physical location.

Where to buy Bitcoin?

There are Deposit systems that use crypto-exchanges. So, to buy Bitcoin, you will first need to top up your balance, buy the digital currency itself, and then withdraw it to your Bitcoin wallet, paying a Commission for withdrawing coins. The cheapest method of buying is buying on the stock exchange. The exchange rate is as close as possible to the market rate.

BTC rate

The current exchange rate of the coin is calculated based on the average price on the largest currency exchanges. For example, you can track the exchange rate on our Bitniex exchange. The Bitcoin exchange rate is constantly changing, during the day it can change by 10% in one direction or another.

The choice of crypto-currency wallet

A cryptocurrency wallet is a place where digital currency will be stored. The most secure method of storage is using paper or electronic wallets.

Wisdom Chian:AccountState

In the current block chain world, there are mainly two ways of record preservation, UTXO mode and Account mode. Bitcoin adopts UTXO model, Ethereum/EOS adopts Account model, and WisdomChian also adopts Account model. Today we will explain in detail why WisdomChian also adopted the account model.
Before introducing the UTXO model and the Account balance model, we have to first introduce the most important concepts and data structures in their two or even all block chain applications, that is, Block. The block chain is actually made up of a list of growing chains, which contains many records, that is, blocks.
📷
UTXO model
In the UTXO model, transactions only represent changes in the UTXO collection. The concept of accounts and balances is a higher abstraction on the UTXO collection. The concept of accounts and balances only exists in wallets. Let's look at some examples to understand the difference.
First, Bitcoin UTXO can not be partially expended. If a user wants to spend 0.5 Bitcoins, but he has 1 Bitcoins in his UTXO collection.He has to send half a Bitcoin to himself to get change at the same time as he sends half a Bitcoin to someone else. If he doesn't send it to himself, he will pay 0.5 Bitcoin to the miner.
📷
Second, Bitcoin itself does not store account balances. Users only need to sign these UTXO with the private key to spend Bitcoins. The digital wallet makes the Bitcoin blockchain look like it has the function of user account balance. This is not the case.
How visual wallets work in Bitcoin
Bitcoin's UTXO system works well, partly because digital wallets can help to accomplish most of the work related to transactions. Including but not limited to:
a) Processing UTXO
b) Storage key
c) Set transaction costs
d) Provide change address
e) Aggregated UTXO (display available, pending and total balance)
Trading in the UTXO model is similar to paper currency. Each account shows how much money it has by calculating the sum of all the paper money (UTXO) in the wallet (corresponding to the wallet address). When we want to spend money, we need to use one or more UTXO with enough cost and we may get a new UTXO. Each UTXO can only be used once, because once UTXO is expended, it will be deleted from the UTXO pool.
All in all, we know that:
Bitcoin blockchain does not store account balance
Bitcoin Wallet Holds secret key
If it is included in the transaction, it will cost the entire UTXO (in some cases, the change is in the form of a new UTXO).
WisdomChain
WisdomChain adopts the same Account transaction structure as ETH. Unlike Ethernet, there are two very different data in Ethernet: permanent data and temporary data. An example of permanent data is a transaction, which, when fully confirmed, will be recorded in the transactiontrie and will never change. An example of temporary data is the balance on a specific Ethereum account address. The balance of the account address is stored in statetrie and will be changed whenever the transaction of the particular account changes. In Ethereum, permanent data (such as mined transactions) and temporary data (such as account balances) are stored separately. Ethereum uses trie data structure to manage data.
And about WisdomChain, when the transaction is initiated, the node will calculate the status information after transaction based on the current state information and transaction content in the virtual machine, and store the relevant hash value of the state information along with the transaction. When the transaction is packaged by a miner, the remaining nodes store data on the Merkletrees to ensure that the state information of their nodes and other nodes in the network is consistent.
So WisdomChain's records are kept like banks. Similar to using ATM / debit cards, banks track the amount of each debit card. When we need to spend money, the bank checks its records to make sure we have enough balance before confirming the transaction.
Of course, WisdomChain uses the Account transaction structure, which inevitably leads to the problems of the Account transaction structure itself. First, there is no dependency between Account model transactions, so the problem of replay attacks needs to be solved. Second, for the realization of lightning network, Plasma and so on, users need more complex Proof mechanism to produce evidence. The state transfer of sub chains to the main chain requires more complicated protocols.

Order Types

Bittrex helps you alternate Limit and Stop-Limit orders.
A limit order or a simple limit order is performed when the asset fee reaches—or even exceeds—the price the trader seeks. To execute such an order, it is required that there's a counter market order on the platform that has the identical fee as the limit order.

Differences between Limit Order and Stop Limit Order

A stop limit order is a mixture of a stop limit order and a limit order. In such an application, charges are indicated—a stop charge and the limit.

Stop Limit Order Purpose

Trade Terminal

Let’s discuss how you could trade conveniently with our service.
The key features include a user-friendly interface and precise currency pair statistics (timeframe graphs, network data, trade volumes, and so forth).
The platform’s top-notch advantage is handy, easy-to-analyze, customizable charts. There is also a column for quick switching between currency pairs and an order panel beneath the fee chart. Such an all-encompassing visual solution helps compare orders efficiently and in one place.
You can use the terminal in a day or night mode; when in the night mode, the icon in the upper-right corner changes and notice the Bittrex trading terminal in night mode is displayed. The main menu consists of 4 sections: Markets, Orders, Wallets, Settings.
Markets are the trade section. Bittrex allows handling over 270 currency pairs.
Orders. To see all open orders, go to OrdersOpen.
To see completed orders, go to OrdersCompleted.
Wallets. The Wallets tab displays many wallets for all cryptocurrencies supported by the exchange and the current balance of each of them.
After refilling the balance or creating a buy or sale order, you will see all actions in the section. Bittrex allows creating a separate wallet for every coin. Additionally, you can see how the coin price has changed, in terms of percentage, throughout the day.
Here’s what you can also do with your wallets:
  • Hide zero balances: hide currencies with zero balance
  • Green and red arrows: replenish balance/withdraw funds
  • Find: search for a cryptocurrency
The Settings section helps manage your account, verification, 2FA, password modification, API connection, and many more.

How to Sell

The process of selling crypto assets follows the same algorithm. The only difference is that after choosing the exchange direction, you need to initiate a Sell order. All the rest is similar: you select the order type, specify the quantity and price, and click Sell *Currency Name* (Sell Bitcoin in our case).
If you scroll the screen, the entire history of trades and orders will be displayed below.

LONG and SHORT

You can make a long deal or a short deal. Your choice depends on whether you expect an asset to fall or rise in price.
Long positions are a classic trading method. It concerns purchasing an asset to profit when its value increases. Long positions are carried out through any brokers and do not require a margin account. In this case, the trader’s account must have enough funds to cover the transaction.
Losses in a long position are considered to be limited; no matter when the trade starts, the price will not fall below zero with all possible errors. Short positions, in contrast, are used to profit from a falling market. A trader buys a financial instrument from a broker and sells it. After the price reaches the target level, the trader buys back the assets or buys them to pay off the initial debt to the broker.
A short position yields profit if the price falls, and it is considered unprofitable the price matches the asset value. Performing a short order requires a margin account as a trader borrows valuable assets from a broker to complete a transaction. Long transactions help gain from market growth; short from a market decline.

Trade via API

Bittrex also supports algorithmic trading through extensive APIs (application programming interface), which allows you to automate the trading process using third-party services.
To create an API key, the user must enable the two-factor authentication 2FA, verify their account, and log in to the site within 3 minutes.
If all the requirements of the system are fulfilled, you can proceed to generate the API key. Log in to your Bittrex account, click Settings. Find API Keys. Click Add new key (Create a new key).
Toggle on / off settings for READ INFO, TRADE, or WITHDRAW, depending on what functionality you want to use for our API key.
Click Save and enter the 2FA code from the authenticator → Confirm.
The secret key will be displayed only once and will disappear after the page is refreshed. Make sure you saved it!
To delete an API key, click X in the right corner for the key that you want to delete, then click Save, enter the 2FA code from the authenticator and click Confirm.

Bittrex Bot, a Trader’s Assistant

Robotized programs that appeared sometimes after the appearance of cryptocurrency exchanges save users from monotonous work and allow automating the trading process.
Bots for trading digital money work like all the other bots: they perform mechanical trading according to the preset parameters.
Currently, one of Bittrex’s most popular trading bots is Bittrex Flash Crash Buyer Bot that helps traders profit from altcoin volatility without missing the right moment.
The program monitors all the market changes in the market every second; also, it even can place an order in advance. The Bittrex bot can handle a stop loss—to sell a certain amount of currency when the rate changes in a favorable direction and reaches a certain level.

8. Secure Platform

Bittrex Global employs the most reliable and effective security technologies available. There are many cases of theft, fraud. It is no coincidence that the currency is compared to the Wild West, especially if we compare the 1800s when cowboys rushed to the West Coast of America to earn and start something new in a place that had no rules.
Cryptocurrency is still wild. One can earn and lose money fast. But Bittrex has a substantial security policy thanks to the team’s huge experience in security and development for companies such as Microsoft, Amazon, Qualys, and Blackberry.
The system employs an elastic, multi-stage holding strategy to ensure that the majority of funds are kept in cold storage for extra safety.
