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 ...
Right now there are thousands of computers connected to the Internet, dutifully calculating SHA-256 hashes and sending their results to other peers on the Bitcoin network. There’s a tremendous amount ...
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 ...
Every crypto gambler faces the same question. Is this game actually fair? A provably fair casino gives players a way to check. It doesn’t ask for trust. It offers math instead. And that math runs on ...
KiviHash-SHA-256 is an IP core implementing the SHA-256 cryptographic algorithm, an one-way hash function compliant to NIST’s FIPS 180-4 standard. It ...
Hash Value Explained: In many technology-related discussions—especially those involving memory cards, CCTV footage, or forensic evidence—you may have heard the term “hash value.” While it sounds ...
Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...
The cryptography world has been buzzing with the news that researchers at Google and CWI Amsterdam have succeeded in successfully generating a 'hash collision' for two different documents using the ...
