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.

How Litecoin Cash fork is going on

In the evening of February 18, on the block 1361111 hardfork of Litecoin Cash happened. All LTC holders were promised LCC coins in the ratio 1 LTC = 10 LCC.
The new cryptocurrency works on the Bitcoin SHA-256 hashing algorithm instead of the Scrypt from Litecoin. It will attract owners of obsolete equipment for bitcoin mining. At the same time, developers promise faster transactions than Bitcoin and Bitcoin Cash.
Litecoin Cash is now developing its own QT wallets. Now a new coin is supported by at least one purse - Coinomi.
The project site also reports that the new coin will be traded on crypto-exchangers Yobit, MercatoX, TradeSatoshi, MeanXTrade and CryptoBridge.
At the time of writing this post LCC on the Yobit exchange is worth 0.00031000 BTC, or $ 3.40. The price since the beginning of trading has more than doubled.
Litecoin founder Charlie Lee said that he has nothing to do with the project, and advised not to invest in it.

“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?

submitted by JPK314 to math [link] [comments]

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.

The claim

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?

submitted by HypoG1 to Bitcoin [link] [comments]

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?

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. 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-256 ist eine der Nachfolger-Hash-Funktionen für SHA-1 (gemeinsam als SHA-2 bezeichnet) und ist eine der stärksten verfügbaren Hash-Funktionen. SHA-256 ist nicht viel komplexer zu programmieren als SHA-1 und wurde in keiner Weise kompromittiert. Der 256-Bit-Schlüssel macht es zu einer guten Partner-Funktion für AES. Es ist im NIST (National Institute of Standards and Technology ... Bitcoin benutzt den SHA-256 Hash-Algorithmus um verifizierbare Zufallszahlen zu erzeugen, die einen vorhersagbaren Aufwand an Rechenzeit für das Erstellen benötigen. Einen SHA-265 Hash mit einem Wert kleiner als einen zuvor berechneten Hash zu erzeugen lößt einen Block und erzeugt damit einige Bitcoins.
