Module bitcoin::blockdata::constants

Blockdata constants

This module provides various constants relating to the blockchain and consensus code. In particular, it defines the genesis block and its single transaction

Constants

COIN_VALUE	How many satoshis are in "one bitcoin"
DIFFCHANGE_INTERVAL	How many blocks between diffchanges
DIFFCHANGE_TIMESPAN	How much time on average should occur between diffchanges
MAX_BLOCK_WEIGHT	The maximum allowed weight for a block, see BIP 141 (network rule)
MAX_SEQUENCE	The maximum allowable sequence number
MIN_TRANSACTION_WEIGHT	The minimum transaction weight for a valid serialized transaction
TARGET_BLOCK_SPACING	How many seconds between blocks we expect on average
WITNESS_SCALE_FACTOR	The factor that non-witness serialization data is multiplied by during weight calculation

Functions

genesis_block	Constructs and returns the genesis block
max_money	The maximum value allowed in an output (useful for sanity checking, since keeping everything below this value should prevent overflows if you are doing anything remotely sane with monetary values).
max_target	In Bitcoind this is insanely described as ~((u256)0 >> 32)
