Developer byte-for-byte rebuilds Satoshi's original 2009 Bitcoin software

  • —SHA-256 hash of the rebuilt file matches the 2009 original
  • —Build environment recreated with Windows XP, GCC 3.4.5 and OpenSSL 0.9.8h
  • —Original compilation dated January 10, 2009, around 23:16 UTC
  • —File matches the January 10 update, not the January 8 release
Why it matters: The rebuild confirms the original client could be produced from the published source, making early Bitcoin history verifiable.
