Template containing all coinbase transaction fields that are set by our miner code. Clients are expected to add their own outputs and typically also expand the scriptSig.
Declared in <node/mining_types.h>
struct CoinbaseTx;| Name | Description |
|---|---|
block_reward_remaining | Block subsidy plus fees, minus any non-zero required_outputs. |
lock_time | The coinbase transaction's locktime (nLockTime). |
required_outputs | To be included as the last outputs in the coinbase transaction. Currently this is only the witness commitment OP_RETURN, but future softforks or a custom mining patch could add more. |
script_sig_prefix | Prefix which needs to be placed at the beginning of the scriptSig. Clients may append extra data to this as long as the overall scriptSig size is 100 bytes or less, to avoid the block being rejected with "bad-cb-length" error. At heights <= 16 the BIP 34 height push is only one byte long, so clients must append at least one additional byte to meet the consensus minimum scriptSig length of two bytes. |
sequence | The nSequence value for the only coinbase transaction input. |
version | The coinbase transaction's version number (nVersion). |
witness | The first (and only) witness stack element of the coinbase input. |
