Hash Game

Hash Game allows you to push your hardware and software ideas to the limit and set new records in the world of hashing. All you have to do is find a message m such that hash(m) is very small or very large. Being able to efficiently produce such hashes would have a huge impact on both security[1] and proof-of-work based cryptocurrencies[2], such as Bitcoin.
This page is heavly inspired by this page which is sadly no longer available. All the old records have been imported.
