int64_t Consensus::Params::nPowTargetTimespan

Definition at line 79 of file params.h.

◆ nRuleChangeActivationThreshold

uint32_t Consensus::Params::nRuleChangeActivationThreshold

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.

Block height at which Segwit (BIP141, BIP143 and BIP147) becomes active.

Note that segwit v0 script rules are enforced on all blocks except the BIP 16 exception blocks.

Definition at line 62 of file params.h.

◆ signet_blocks
