Quantum computers would need to become around one million times larger than they are today in order to break the SHA-256 algorithm that secures bitcoin. For a while, there has been talk that bit ...

Google is encouraging businesses and security practitioners to utilize cryptographic hashes like SHA-256, a Secure Hash Algorithm which serves as the basis of the Bitcoin network’s proof of work ...

Cryptocurrency has undeniably transformed the financial landscape, with Bitcoin and Litecoin emerging as trailblazers in the realm of decentralized digital currencies. At the heart of these blockchain ...

The first Secure Hash Algorithm (SHA) was originally developed by the NSA and there are many different versions now (Bitcoin uses SHA256). It’s a set of instructions for how to jumble up the data in a ...

Could an IBM mainframe from the 1960s mine Bitcoin? The idea seemed crazy, so I decided to find out. I implemented the Bitcoin hash algorithm in assembly code for the IBM 1401 and tested it on a ...

The SHA-256 hash function used for Bitcoin isn’t really that hard to work out by hand. The problem, though, is that it takes a 64 byte value, sends it through an algorithm, and repeats that ...

It's important to stress that the cryptography underpinning the bitcoin network, which makes use of the more secure SHA256 algorithm, is not directly affected by the discovery.

Bitcoin ( mining behemoth Bitmain has officially released two new 7nm (nanometer) “Antminer” crypto mining machines, designed to mine with the SHA256 algorithm.
