◆ BuriedDeployment

A buried deployment is one where the height of the activation has been hardcoded into the client implementation long after the consensus change has activated.

See BIP 90.

Function Documentation

◆ CheckTxInputs()

bool Consensus::CheckTxInputs ( const CTransaction tx,
TxValidationState state,
const CCoinsViewCache inputs,
int  nSpendHeight,
CAmount txfee 
)

Check whether all inputs of this transaction are valid (no double spends and amounts) This does not modify the UTXO set.

This does not check scripts and sigs.

Parameters
[out]txfeeSet to the transaction fee if successful. Preconditions: tx.IsCoinBase() is false.
