An implementation of the [ZIP-317] fee calculations for UnminedTxs:
Enums§
- Error
- Errors related to ZIP-317.
Constants§
- BLOCK_
PRODUCTION_ 🔒WEIGHT_ RATIO_ CAP - The recommended weight ratio cap for ZIP-317 block production.
weight_ratio_cap
in ZIP-317. - BLOCK_
UNPAID_ ACTION_ LIMIT - If a tx has more than
BLOCK_UNPAID_ACTION_LIMIT
“unpaid actions”, it will never be mined by the Recommended algorithm for block template construction, implemented in Zebra here. - GRACE_
ACTIONS 🔒 - The number of grace logical actions allowed by the ZIP-317 fee calculation.
- MARGINAL_
FEE 🔒 - The marginal fee for the ZIP-317 fee calculation, in zatoshis per logical action.
- MEMPOOL_
TX_ FEE_ REQUIREMENT_ CAP - The fee cap for
MIN_MEMPOOL_TX_FEE_RATE
minimum required mempool fees. - MIN_
BLOCK_ 🔒PRODUCTION_ SUBSTITUTE_ FEE - The minimum fee for the block production weight ratio calculation, in zatoshis. If a transaction has a lower fee, this value is used instead.
- MIN_
MEMPOOL_ TX_ FEE_ RATE - The minimum fee per kilobyte for Zebra mempool transactions. Also used as the minimum fee for a mempool transaction.
- P2PKH_
STANDARD_ 🔒INPUT_ SIZE - The standard size of p2pkh inputs for the ZIP-317 fee calculation, in bytes.
- P2PKH_
STANDARD_ 🔒OUTPUT_ SIZE - The standard size of p2pkh outputs for the ZIP-317 fee calculation, in bytes.
