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 null OP Codes are in Bitcoin for the day a HASH vulnerability is discovered and we need to move away from SHA 256 etc. There were 10 of these. They are needed for the future.... There are real reasons for these to exist in a system expected to last 100 years“

How is SHA-256 not reversible? I.E. Why couldn't you find all acceptable values for bitcoin hashes by reverse-engineering the starting bytes?

In May 2013, Dan Kaminski, renowned security researcher, bet 10BTC against Jeff Garzik, Bitcoin core developer, about whether Bitcoin's underlying Proof-of-Work hash function (Sha-256) would be replaced within 12 months.

Hey, Jeff - did that full-of-himself Kaminski pay up?

If I somehow managed to decrypt SHA-256 hashing and used that information to mine thousands of bitcoin, would that be illegal?

Tech question: While downloading Bitcoin ABC, where are the signatures of the SHA hashes for the client?

If somebody breaks into their website and replaces the clients + hashes, you have a beautiful way to steal coins.
Bitcoin Unlimited has their hashes with 3 signatures. (As long as people make sure that their addresses don't change, it's pretty much impossible to sneak in a different SHA256 hash of the download for their client.)
Does Bitcoin ABC do anything similar? I haven't found it yet.
TIA.

I want to prove 10 years from now that I wrote a piece of text today. How can I record a SHA-512 hash of my text on the blockchain today, using only Bitcoin Core (no 3rd party online tools)?

Yeah.

Would a neural network be able to learn to mine Bitcoin (that is, learn to generate a SHA-256 hash with many leading zeroes)?

If so, what kind of neural network would be the most suitable for this kind of learning?

BitCoin verwendet den SHA-256 Hash-Algorithmus, um nachweislich “zufällige” Zahlen in einer Weise zu erzeugen, die einen vorhersehbaren CPU-Aufwand erfordert. Das Erzeugen eines SHA-256-Hash mit einem Wert kleiner als das aktuelle Ziel löst einen Block auf und gewinnt einige Coins. Hash-Rate oder Hash-Power ist etwas sehr Kritisches und integraler Bestandteil von Bitcoins Netzwerk aus ... This powerful feature of the SHA-256 hash function makes it ideal for application within the Bitcoin network. The SHA-256 hash function is utilised within the Bitcoin network in two main ways: Mining; Creation of Bitcoin addressess ; Mining. Mining is a process by which new coins are introduced into the existing circulating supply of the Bitcoin protocol, as well as a method used to secure the ... SHA steht für „Secure Hash Algorithm“ und ist tatsächlich einer der wenigen wirklich sicheren Hashalgorithmen auf der Welt. Entwickelt wurde SHA-256 als Teil des SHA-2 Algorithmus von der amerikanischen Nachrichtendienstbehörde NSA im Jahr 2001. Da die NSA diesen Algorithmus entworfen hat, fürchten besonders viele Laien, dass er deswegen unsicher ist. Diese Reaktion ist keineswegs ... Bekannte Hash-Verfahren sind z. B. CRC32, MD5, SHA-1 oder SHA-256. In den nachfolgenden Beispielen wurde das Hashverfahren CRC32 verwendet, welches sehr kurze Hashes generiert. Heutzutage verwendet man eher SHA-1 oder besser noch SHA-256, u.a. um eine Kollision (zwei unterschiedliche Eingaben führen zum selben Hashwert) zu vermeiden. SHA-3 (Secure Hash Algorithm Version 3), also called Keccak, is a unidirectional function for generating digital prints of the selected length (the standard accepts 224, 256, 384 or 512 bits) from input data of any size, developed by a group of authors led by Yoan Dimen in 2008 and adopted in 2015 as the new FIPS standard.The algorithm works by means of the mixing function with compression to ...
