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.

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 Thread for Q&A questions: http://3b1b.co/questions 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 a 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?

Взлом Биткоина или уязвимость Супер-криптовалюты. Мифы о надёжности Bitcoin.
 
08:45
ВЗЛОМ BITCOIN ИЛИ УЯЗВИМОСТЬ СУПЕР КРИПТОВАЛЮТЫ. НАДЁЖНОСТЬ БИТКОИНА. 1. Уязвимость всей надстройки такая же, как и у обычной цифровой валюты. 2. После того, как похищение осуществили, данную транзакцию невозможно остановить или развернуть. Кроме того, невозможно отследить и последующее движение денег. 3. Алгоритм SHA-1. В 1995 г., примерно через десять лет после обнародования SHA-1, он был объявлен ненадежным, а в этом 2017 году был взломан. Алгоритм SHA-256 вероятно будет взломан через 10 лет. 4. Для любого адреса биткоина существует множество подходящих пар частных/публичных ключей. 5. Нахождения ключа с минимальным количеством значений. 6. Алгоритмов без уязвимостей не существует. 7. При осуществлении обманной транзакции достаточно поменять только некую ее часть, подпись под которой будет соответствовать оригинальной.

Это лучшие пулы для майнинга, которые объединены в один общий мультипул (multipool), на котором можно добывать такие монеты, как биткоин (bitcoin), лайткоин (litecoin), дэш (dash) и др. Майнинг на пуле, в настоящее время, это единственный способ добывать криптовалюту с небольшим количеством хэшрейта. Сайт называется mining dutch. На нем есть как непосредственно сам пул для майнинга биткоинов, так и другие пулы для майнинга bitcoin, но посредством обмена на биржах. В видео я покажу доходность этого пула на примере добычи лайткоин. Многие предлагают лучшие пулы, но среди них сложно выбрать действительно хороший пул, т.к. не только сам майнинг пул (mining pool) определяет доходность bitcoin mining. У себя на канале Rich Man - заработок в интернете, я рассказываю не только о том, как заработать, но и как майнить. Майнинг биткоинов (как и другой майнинг криптовалюты) сейчас стал очень популярен, также, как и сама криптовалюта. Логично, что все хотят узнать, что же такое майнинг (mining), а вместе с тем и пул.

Биткоин на данный момент использует следующие криптографические алгоритмы: ECDSA, SHA-256 и RIPEMD-160.

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.

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.

What is Incakoin? Incakoin is an experimental new digital currency that enables instant payments to anyone, anywhere in the world. Like Bitcoin, Incakoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Forked from Bitcoin reference wallet 0.8.5 Incakoin Wallet on Github Wallet Source Files Incakoin version v1.0.0.0-oro Incakoin-256(optimized) faster than Scrypt and faster than SHA-256 in Sphlib C code The algorithm was written as a candidate for SHA-4, Based on three layers using two candidate code from the Sphlib 2.1 library and reduced the round function to 4 rounds. Incakoin Specifications: Block reward is 420 NKA coin + inflation (square root of (var-difficulty + block height)) Halfing of block reward every 3 months Cap in place to reduce the difficulty jumps upwards Block and retarget time is 30 seconds 190 Million coins Block maturity 5000 www.incakoin.com

Who generates the nonce? What makes it random? How is nonce-guessing important to the competitive process of mining? What happens if the hashing algorithm (SHA-256) was compromised? Is quantum computing a threat? More on nonces and the mining process: https://github.com/bitcoinbook/bitcoinbook/blob/8ae3c056fb257111bda8883d9d204e8476f9870c/ch09.asciidoc More about the SHA-1 collision: https://security.googleblog.com/2017/02/announcing-first-sha1-collision.html More about SHA-1 and Bitcoin: https://bitcoin.stackexchange.com/questions/75135/is-sha-1-used-in-bitcoin CORRECTION: At 5:53, I described what a collision was. However, the definition I outlined was actually for a pre-image attack, which is distinct from collision attacks. The subtitles have been edited to include the correction. https://en.wikipedia.org/wiki/Preimage_attack These questions are from the MOOC 7.2 and 9.2, which took place on February 26th 2017 and February 23rd 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.
