Mining Bitcoin With Pencil and Paper - Gizmodo

BitcoinSoV

BSoV: The first mine-able, deflationary, open sourced, decentralized cryptocurrency Hedge to act as a Store of Value against the monetary inflation of fiat currency. BSoV is mined using a simple Keccak256 (Sha3) algorithm. There is No ICO, No Pre-mine, and No Governance. This allows for BSoV to be completely decentralized and fairly distributed. With each transfer of BSoV tokens, 1% of the total transaction is burned forever.

0xBitcoin

The first pure mined ERC20 Token for Ethereum, using the soliditySHA3 hashing algorithm. This is a smart contract which follows the original Satoshi Nakamoto whitepaper to form a fundamentally sound trustless currency. This combines the scarcity and fair distribution model of Bitcoin with the speed and extensibility of the Ethereum network. Thus, it is named 0xBitcoin or 0xBTC where 0x represents the Ethereum Network and ecosystem.

One of the ideas which stuck with me is hashing and its power to verify the integrity of data securely. It inspired this visualization project entitled Cloud Hashes. Since Bitcoin uses the SHA-256 algorithm, my artwork visualizes and references many elements of this hash function.

The entire bitcoin protocol depends on the SHA-256 hashing algorithm. What would hypotetically happen if it is broken (not by brute force, laws of the universe and all that)?

Use weaker hash from strong hash to reduce size ?

Hello,
I was wondering if it would make sense to use a weaker hash algorithm (e.g. MD5 or SHA-1) on a hash generated by a stronger one (e.g. SHA-2, SHA-3) to reduce the storing size of the hash.Every keys will be hashed 2 times (e.g key -> SHA-2 -> MD5).
I was reading The bitcoin block size limit controversy (link) and was wondering if reducing the hash of Previous Block and Merkel Root could reduce the size of a block.
What are the consequences of doing that?

Edit: thank you for all your explanations!

Overwhelmed!

I am not really savvy in coding. So, the sequences of letters and numbers involved are driving me a bit crazy.
Here is what I have done:
Downloaded AwesomeMiner and as a wallet, I used Electrum. Surprisingly, when I check the bitcoin reddit, these two apps are not mentioned. Am I in the wrong track?
Now, in AM app, I used SHA-256 algorithm, BFGMiner(5.4.2), as as a pool, I used bsod mining pool.
BUT, this is what I got:
> [2020-10-16 20:18:53] No devices detected!
> [2020-10-16 20:18:53] Waiting for devices
> [2020-10-16 20:18:53] Probing for an alive pool

> [2020-10-16 20:18:53] Probing for an alive pool
Mining Engine Process started, PID: 10480
Even I understand that the mining is not working at all.
Just wondering what should I do now?

However, I check out some video on the bitcoin reddit, so I will start from there.

Any advices are welcome.

Checker Thread (A list of hacked clients for easy reference)

Community contribution is the only way this thread will be useful. This is a WIP! More clients will be added as time goes on!
Quick note: The vast majority of these are files supplied by the community -- some may not work. The person who sent me 9b9t says it doesn't work, but I have not personally tested. Please let me know if it works or does not work.

Some additional notes:
I am open to community criticism so long as it can actually be used to benefit the thread. Issues with formatting, approach, client choice, etc. are all great things to come talk to me about so I may improve. However, people keep commenting the same things over and over and over — “VirusTotal can’t catch X” is a popular one — and I don’t have time to deal with it. If you have a security concern, you are more than welcome to raise it. HOWEVER, do not make unreasonable requests of me — I work, in addition to that I have a social life, I have responsibilities at home as well. This is a side thing that I do when I have the time. A lot of people have suggested looking through bytecode to determine if a client is malicious. I do not have the time to do this for every client. If you are willing to help and do more than say “you should do more than you already are, even though you have a job and a life outside of an obscure subreddit,” feel free to DM me. People who take the broken record approach and say things that are already covered in the thread, or refuse to offer help and just post complaints, will be blocked and ignored. I’m all down for making this post better, but I’m not gonna waste my time with people who won’t work with me. Thank you for your help!

BIG THANKS TO u/jpie726 FOR HIS MASSIVE CONTRIBUTIONS! WITHOUT HIM THIS LIST WOULD BE SIGNIFICANTLY LESS EXPANSIVE. GO UPVOTE THIS MAN INTO HEAVEN, HE DESERVES IT!

Eventually I would like to make a Python script that takes care of all the necessary tasks to install these clients. Python itself is available through the Windows Store as well as on Python's website, or through various other installers. It will install any additional dependencies via Pip and will use Curl to retrieve the files. Anyone interested in helping with this script is more than welcome to do so, if you wish. The two options for assisting me would be as follows:
1. You can install Visual Studio Code or Atom and work with me directly through those applications (more details soon™)
2. A GitHub page may be made and you could submit pull requests through that and edit the script alone.

#######################################################################
There is a misconception that I am only here for free paid clients.
1. I can't use a paid client unless I have access to a cracked version, an account, and the HWID bound to said account.
2. People are also saying there's a way for clients to track if someone leaks them. While I suppose this is possible if they bothered to put in the absurd amount of effort it would take, it would give them no benefit and it would do no good as I am not running the software on my desktop -- I am sending the software to VirusTotal, grabbing the SHA-256 checksum, and deleting the file.
3. If all you're going to do is post that "VirusTotal can't catch x" or "muh client" do not waste my time, and don't waste yours. You will be ignored in favor of people who will actually help me construct what I hope to be a megathread for this subreddit, FOR YOU GUYS. I mean jeez, someone's trying to help and half the fucking responses are "muh client" like come on. No wonder this fucking subreddit is dead, sheesh. If someone's trying to help you and you just step on their toes that's just not very cool, not everyone is trying to scam you. I do just be trying to help people who come here doe.
4. If you have concerns, raise them respectfully. Do not attack me, you will be ignored or if I feel so inclined I will give you 110% of the shit you give me right back to you. I will answer questions, I will elaborate on my goals, I will take helpful advice. Everything else will be outright ignored, and misinformation will be countered. That is all, thread below.
#######################################################################

I named this the Checker Thread to make it easy to search for in the subreddit. Enjoy.Below will be a list of hacked clients, with VirusTotal links, SHA-256 hashes, direct download links (skipping ad pages) and eventually features for each client. I'd also like to add what servers they do and don't work on, but I need the community to help with that.
The only client I use is Impact, send me additional clients in the comments and they will be added to this list.

Note about SHA-256 hashes:
SHA-256 hashes are a hash of a file produced algorithmically. This type of hash was developed by the United States National Security Agency, and is typically used to verify that files are what they are supposed to be. Widely used in cryptographic applications such as SSH, APT repositories, transactions on websites, verifying files, Bitcoin, and more. It is very common. This type of cryptographic hash has been in use since 2001. An SHA-256 hash will be the exact same for the same file regardless of the source of the file, so if your hash is different from the one listed here you do not have the legitimate installer OR the hash is not up-to-date.

Note about VirusTotal tests:
Several people have pointed out to me something I feel should be brought up in the main thread. VirusTotal is not a catch-all, just as your typical antivirus software is not a catch-all. It will not catch everything. It should be used as a general guideline only. Clean VirusTotal tests do not guarantee your safety, although if the program passes all ~70 or so antivirus engines it's probably safe to use. Any additional malicious activity should be caught by your antivirus program's heuristics. I take no responsibility for anything that is malicious, but I can say in good conscience that I have done everything I can to ensure that everything on this thread is safe. Keep in mind that programs that trip VirusTotal may still be safe to use, antivirus programs often pick up injectors as malware or Trojans because that's how those types of viruses behave in the real world. Use your best judgement. If your best judgement is not good enough, do not use these programs. You have been warned.

RESEARCH REPORT ABOUT ARYACOIN

RESEARCH REPORT ABOUT ARYACOIN
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/a7jv4azk86u51.jpg?width=1600&format=pjpg&auto=webp&s=e4a4dbb5afacd5747076beaa59e6343b805c3392

ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.
Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:
  • Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.
  • Instant operations: Aryacoin makes it quite easy for you to use your digital wallet and perform various operations with it.
  • Safe and secure: all your data is stored encrypted and can only be decrypted with your private key, seed, or password.
  • Strong security: The system has no control over your wallet. You are 100% in charge of your wallet and funds.

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
  • The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
  • The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
  • The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
  • There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
  • The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
  • The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

The Truth about Bitcoin?

Part 1/4 - NSA Connection:
First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001.
SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits.
Moreover, all outputs appear completely random and offer no information about the input that created it.
The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses.
Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean?
Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views.
As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that.
As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential.
In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto.

Part 2/4 - 'Crypto Market':
Most of the crypto market is a scam.
By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010:
"if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin...
Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way."
To which Bitcoin OG Gavin Andresen replies:
"I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles."
"I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)."
Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access).
On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful.
This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times.
In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who:
A) Think they can outsmart professional traders with actual risk management skills; and
B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions.

Part 3/4 - CBDCs:
The Fed and Central Banks around the world have printed themselves into a corner.
Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels.
This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster.
The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing.
The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality.
They, obviously, know this (as it is by design).
The issue (for them) is that more and more people are starting to become aware of this.
Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free.
It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums.
Now...back to the powers that be.
Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state?
More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system.
This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment.

Part 4/4 - Bitcoin:
What about Bitcoin?
Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World.
But what about Bitcoin's reputation?
Bankers hate it.
Warren Buffett hates it.
Precisely, and the public hates bankers.
Sure, the investing public respects Buffett, but the general public perception of anyone worth $73 billion is not exactly at all time highs right now amid record wealth inequality.
In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion.
For example, the market cap of Gold is around $9 trillion, which is 50x the Market Cap of Bitcoin.
Money has certain characteristics.
In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation.
Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation.
One of the key strengths of Bitcoin is the fact that the Network is decentralised...
Many people don't know that PayPal originally wanted to create a global currency similar to crypto.
Overall, a speculative thesis would be the following:
Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race.
Trusted third parties are security holes.
Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion.
In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale.
At the time, he was looking for signs of extraterrestrial life within cosmic signals.
The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation.
Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W);
A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.
What are your thoughts?
Is it true...or false?

Since SHA-256 is invented by NSA, why do we consider it safe?

I am at fault of oversimplifying, but if Bitcoin uses SHA-256 for hash creation, and SHA-256 is created by NSA, wouldn't that endanger Bitcoin's independence?

ACIS-mining and its 3 best algorithms

ACIS-mining and its 3 best algorithms
Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms.
📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business.
📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks.
📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11.
🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts.
🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency.
🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function.
Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.

The Truth about Bitcoin?

Part 1/4 - NSA Connection:
First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001.
SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits.
Moreover, all outputs appear completely random and offer no information about the input that created it.
The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses.
Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean?
Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views.
As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that.
As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential.
In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto.

Part 2/4 - 'Crypto Market':
Most of the crypto market is a scam.
By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010:
"if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin...
Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way."
To which Bitcoin OG Gavin Andresen replies:
"I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles."
"I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)."
Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access).
On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful.
This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times.
In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who:
A) Think they can outsmart professional traders with actual risk management skills; and
B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions.

Part 3/4 - CBDCs:
The Fed and Central Banks around the world have printed themselves into a corner.
Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels.
This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster.
The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing.
The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality.
They, obviously, know this (as it is by design).
The issue (for them) is that more and more people are starting to become aware of this.
Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free.
It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums.
Now...back to the powers that be.
Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state?
More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system.
This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment.

Part 4/4 - Bitcoin:
What about Bitcoin?
Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World.
But what about Bitcoin's reputation?
Bankers hate it.
Warren Buffett hates it.
Precisely, and the public hates bankers.
Sure, the investing public respects Buffett, but the general public perception of anyone worth $73 billion is not exactly at all time highs right now amid record wealth inequality.
In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion.
For example, the market cap of Gold is around $9 trillion, which is 50x the Market Cap of Bitcoin.
Money has certain characteristics.
In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation.
Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation.
One of the key strengths of Bitcoin is the fact that the Network is decentralised...
Many people don't know that PayPal originally wanted to create a global currency similar to crypto.
Overall, a speculative thesis would be the following:
Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race.
Trusted third parties are security holes.
Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion.
In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale.
At the time, he was looking for signs of extraterrestrial life within cosmic signals.
The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation.
Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W);
A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.

The SHA-256 hash algorithm used by Bitcoin The SHA-256 hash algorithm takes input blocks of 512 bits (i.e. 64 bytes), combines the data cryptographically, and generates a 256-bit (32 byte) output. About []. SHA-256d was proposed in one of the Ferguson/Schneier books like so: . SHA-256d(x) = SHA-256(SHA-256(x)) The motivation for this construction is to avoid length extension attacks. Example []. An example is this protocol designed to provide mutual proof that each party has made some minimum number of evaluations of some 256-bit hash function H (note: Alice performs the odd steps, and ...

When mining bitcoin, the hashcash algorithm repeatedly hashes the block header while incrementing the counter & extraNonce fields. Incrementing the extraNonce field entails recomputing the merkle tree, as the coinbase transaction is the left most leaf node. The block is also occasionally updated as you are working on it. SHA-256 is a member of the SHA-2 cryptographic hash functions designed by the NSA. SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed "hash" (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity.
