SHA256d proof of work

The proof-of-work algorithm is SHA256(SHA256(header bytes)).

  • Initial / minimum: 18 leading-zero bits
  • Maximum: 40 leading-zero bits
  • Target interval: 60 seconds

The node reports current bits as powLeadingZeroBits in nvc_getConsensusInfo. Hash rate is not a consensus field and is not published as a protocol statistic.
