Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

The SHA-256 hash function remains a cornerstone of modern cryptographic systems, underpinning applications ranging from blockchain mining to secure communications in IoT networks. Recent advancements ...

The latest version of Linus Torvalds' Git version-control system brings experimental support for the SHA-256 cryptographic hash, moving it away from its reliance on the less safe SHA-1. Google and ...

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 ...

A breakdown of what type of risks quantum computing poses to Bitcoin, and how worried users of the network should be. In the early 2020s, quantum computing hit the public spotlight as a potential ...
