data cryptographically, and generates a 256-bit (32 byte) output. The, computer History Museum in Mountain View has two working IBM 1401 mainframes. I implemented the Bitcoin hash algorithm in assembly code for the IBM 1401 and tested it on a working vintage mainframe. International Business Machines Inc. IBM 1009 Data Transmission Unit. Although each round of SHA-256 doesn't change the data much, after 64 rounds the input data will be completely scrambled, generating the unpredictable hash output.

Wt is based on the input data, slightly processed. It uses 6-bit characters and doesn't provide bit operations. But once you find an input that gives the value you want, it's easy for anyone to verify the hash. Could an IBM mainframe from the 1960s mine Bitcoin? It doesn't even handle binary arithmetic, using decimal arithmetic instead. Is becoming the biggest backer of a technology that underpins the Bitcoin digital currency.
