Parameters that influence chain consensus.

Fields

network: Network

Network for which parameters are valid.

bip16_time: u32

Time when BIP16 becomes active.

bip34_height: u32

Block height at which BIP34 becomes active.

bip65_height: u32

Block height at which BIP65 becomes active.

bip66_height: u32

Block height at which BIP66 becomes active.

rule_change_activation_threshold: u32

Minimum blocks including miner confirmation of the total of 2016 blocks in a retargeting period, (nPowTargetTimespan / nPowTargetSpacing) which is also used for BIP9 deployments. Examples: 1916 for 95%, 1512 for testchains.

miner_confirmation_window: u32

Number of blocks with the same set of rules.

pow_limit: Uint256

Proof of work limit value. It contains the lowest possible difficulty.

pow_target_spacing: u64

Expected amount of time to mine one block.

pow_target_timespan: u64

Difficulty recalculation interval.

allow_min_difficulty_blocks: bool

Determines whether minimal difficulty may be used for blocks or not.

no_pow_retargeting: bool

Determines whether retargeting is disabled for this network or not.

Methods

impl Params

pub fn new(network: Network) -> Self
