With all the stats and metrics out there I was surprised I could not find this out. Has anyone ever determined the highest nonce in a block?

  • Another interesting question would be: "What has been the smallest winning hash so far?"

    @Geremia: That would be 0000000000000000000000bb5b432a764ad6c7acf677dcd99161abfdf68e698e, for block 500174. Mar 11, 2018 at 4:15
  • @NateEldredge How did you determine that?

  • @Geremia: I wrote a script to scan my local copy of the blockchain. Sep 2, 2018 at 15:23

Through block 512961, the highest (little-endian) nonce value to date is 4294956079 (0xffffd42f), in block 219742.

The lowest is 1082 (0x0000043a), in block 67071.

The script I used to gather this data is at https://github.com/neldredge/bitcoin-blocks.

  • I'm jealous of your ability to look that up - thanks!
