The World's Most Popular Algorithm: SHA 256 and Bitcoin
 
05:59
No one on Earth knows how to reverse the SHA-256 hash function. Yet it's really easy to compute one-way. You could make billions of dollars if you solved this mathematics problem. SHA-256 might also be the world's most popular algorithm - it's computed quintillions of times per second in the race for mining Bitcoin. It has some amazing properties, is useful for digital signatures, cryptography, authentication, and is a central part of the Bitcoin protocol. Bitcoin and other "crypto-currencies" rely on one-way hash functions like the SHA-256 algorithm to secure the blockchain where all the transactions are kept. In this video, I explain some of the big-picture ideas behind this one function. Other cryptocurrencies use similar ideas. Comments, suggestions, or errors? Let me know in the comments, and I'll fix them in an upcoming follow-up video (coming late July 2019) ---- Links ------ Wikipedia about SHA-256: https://en.wikipedia.org/wiki/SHA-2 Current Bitcoin difficulty: https://www.coinwarz.com/difficulty-charts/bitcoin-difficulty-chart Big number calculator: https://defuse.ca/big-number-calculator.htm ---- Credits ---- BitCoin & Money Photo: Copy Link to Credit: (CC-BY 4.0) Cryprocurrency360.com https://www.flickr.com/photos/bitcoin-crypto/41063960960 Bitcoin mining farm: (CC-BY 2.0) Marko Ahtisaari - https://www.flickr.com/photos/moia/ Fourier Transform Graph: (CC-BY 4.0) Jake http://pgfplots.net/tikz/examples/author/jake/ Wikipedia Hash Function Algorithm illustrations: https://en.wikipedia.org/wiki/SHA-2 (CC-BY-SA)

Mining Bitcoin with pencil and paper
 
07:52
Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day. For details, see http://righto.com/sha

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Home page: https://www.3blue1brown.com/ Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives the desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

How Does SHA256 Work?
 
04:53
Since SHA1 has been broken, SHA256 is seen as one of the contenders to replace it. In this video I review why it might be needed and how it functions on a low and high level perspective by stepping through the algorithm with an example by converting abc to its digest. I did a similar explanation for SHA1 in another video so check that out.

В видео я объясняю и показываю почему. Майнинг bitcoin, это практически основной мой доход. Для этого нужен asic antminer s9, который работает на алгоритме sha256. Я нашел для себя лучший пул, и продолжаю про него рассказывать. Сейчас выгоден только майнинг на пуле, но не каждый майнинг пул подойдет. Чтобы найти хороший пул, я много их тестировал, и пул для майнинга viabtc оказался тем самым. Мой asic bitmain antminer работает на этом mining pool давно. Сейчас лидер рынка асиков, это bitmain antminer. Продолжительное время майнинг считался прибыльным занятием, но майнинг 2018, показал себя с противоположной стороны, доходность майнинга снизилась. Однако, асик для майнинга биткоин (bitcoin) еще держится. Ранее я уже рассказывал, как майнить, и как настраивать asic miner под конкретный пул для майнинга bitcoin.

What is Hashing on the Blockchain?
 
04:48
What is Hashing on the Blockchain? https://blockgeeks.com/guides/what-is-hashing/ Cryptographic hashing is a key feature in the security and efficiency of blockchains. If you've ever wondered how so much data can be stored securely on every node in the network, hashing is a big part of the answer! We'll cover all the basics you need to know in this video! For more blockchain guides, courses, and videos, visit us at blockgeeks.com! Cryptographic hash functions A cryptographic hash function is a special class of hash functions which has various properties making it ideal for cryptography. There are certain properties that a cryptographic hash function needs to have in order to be considered secure. Let’s run through them one by one. Property 1: Deterministic This means that no matter how many times you parse through a particular input through a hash function you will always get the same result. This is critical because if you get different hashes every single time it will be impossible to keep track of the input. Property 2: Quick Computation The hash function should be capable of returning the hash of an input quickly. If the process isn’t fast enough then the system simply won’t be efficient. Property 3: Pre-Image Resistance What pre-image resistance states is that given H(A) it is infeasible to determine A, where A is the input and H(A) is the output hash. Notice the use of the word “infeasible” instead of “impossible”. We already know that it is not impossible to determine the original input from its hash value. Let’s take an example. Suppose you are rolling a dice and the output is the hash of the number that comes up from the dice. How will you be able to determine what the original number was? It’s simple all that you have to do is to find out the hashes of all numbers from 1-6 and compare. Since hash functions are deterministic, the hash of a particular input will always be the same, so you can simply compare the hashes and find out the original input. But this only works when the given amount of data is very less. What happens when you have a huge amount of data? Suppose you are dealing with a 128-bit hash. The only method that you have to find the original input is by using the “brute-force method”. Brute-force method basically means that you have to pick up a random input, hash it and then compare the output with the target hash and repeat until you find a match.

In the early days of bitcoin mining, it was feasible to use a powerful CPU. Once the mining software was modified to support graphic cards, GPUs became the new preferred form of mining hardware. Eventually, FPGAs and ASICs took over. By making use of these application-specific integrated circuits, mining bitcoin has become a very expensive process. These machines require a lot of electricity, even though they have become more energy-efficient as of late. #SHA-256 #Algorithm #SHA #256

What the Hash? - How Bitcoin and Blockchains use Hash Functions
 
05:55
Learn what a hash function does and how it is used in bitcoin and blockchains in general. Leave questions in the comments and we'll do our best to answer! One way hash functions are used in the bitcoin network is to help secure transactions. They do this by creating a very difficult mathematical problem that miners must try and solve which in turn creates proof-of-work (POW) which leads to consensus across the network.

Bitcoin Q&A: Migrating to post-quantum cryptography
 
06:47
Keywords/phrases: Quantum cryptography, quantum cryptoanalysis, quantum computing. Bitcoin uses SHA-256. In cryptography there is a 20-30 year lifecycle for an algorithm before it gets exceeded by new technologies and developments in mathematics. Both the signing and hashing algorithms can be upgraded in Bitcoin if there is a need to do that. Quantum cryptography represents a threat only if unevenly distributed in commercial sectors. If it is available to only one actor, and not all actors, they are unlikely to use it against Bitcoin; instead they're going to keep it secret and use it when they're threatened by ex. cryptographically secure nuclear weapons. Intelligence agencies who have that kind of significant computing advantage don't use it until there is a dire emergency, because once you use it everyone will know you have it. After that all the algorithms get changed, so you better make it good. If it is widely available, all the miners update to quantum computers and we're going to be looking at several orders of magnitude in improvement, because running one is neither free nor easy. We don't know what the economics will be yet, but we will solve problems when it's necessary. Corporations and governments are not going to be happy with Bitcoin. Kings were not happy and yet the revolution happened anyway. Bitcoin is a global and technological revolution. They have adapted to new technologies for hundreds of years. The fact that they won't be happy doesn't concern me, because Bitcoin is a system that doesn't require their permission, approval, or cooperation. They can pretend it's going away but it isn't. We can talk all day about whether the government should or shouldn't regulate Bitcoin, but the real question is whether they can. They can regulate at the edge, the behaviour of users, but they can't regulate Bitcoin itself. Bitcoin is exciting because it introduces a new choice; it's not saying you can't do the old way (hierarchical central banking, border-restricted jurisdictions for currencies ), it's saying we can also do this.
