• Started in ProcessNewBlock, main.cpp:4258
  • Calls CheckBlock, defined at ab2b7c0969/src/main.cpp (L3930)
    • Calls CheckBlockHeader ab2b7c0969/src/main.cpp (L3900)
      • checks that the block version is not too old
        • this requires no information
      • checks that the equihash solution is valid
        • ab2b7c0969/src/pow.cpp (L96)
        • requires no information except n, k params
      • checks that the proof of work parameters are valid
        • requires the current proof of work amount params.powLimit
    • Checks the Merkle root
    • Checks size limits
    • Checks that the first transaction is coinbase, and the rest are not
    • Calls CheckTransaction for each transaction
    • Sum up "LegacySigOps" for each transaction and check that it's less than some maximum
