Module zip317

An implementation of the [ZIP-317] fee calculations for UnminedTxs:

• conventional fee
• block production transaction weight

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.
