• Logging and RPC

  • Bitcoin Core now reports a debug message explaining why transaction inputs are non-standard.

  • This information is now returned in the responses of the transaction-sending RPCs submitpackage, sendrawtransaction, and testmempoolaccept, and is also logged to debug.log (if mempoolrej

• debug category is enabled) when such transactions are received over the P2P network.

• This does not change the existing error code bad-txns-nonstandard-inputs, but instead adds additional debug information to it.
