◆ nMinerConfirmationWindow

uint32_t Consensus::Params::nMinerConfirmationWindow

Definition at line 106 of file params.h.

◆ nMinimumChainWork

uint256 Consensus::Params::nMinimumChainWork

The best chain should have at least this much work.

Definition at line 120 of file params.h.

◆ nPowTargetSpacing

int64_t Consensus::Params::nPowTargetSpacing

Definition at line 112 of file params.h.

◆ nPowTargetTimespan

int64_t Consensus::Params::nPowTargetTimespan

Definition at line 113 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.

Definition at line 105 of file params.h.

std::map<uint256, uint32_t> Consensus::Params::script_flag_exceptions

Hashes of blocks that.

  • are known to be consensus valid, and
  • buried in the chain, and
  • fail if the default script verify flags are applied.

Definition at line 83 of file params.h.

◆ SegwitHeight

int Consensus::Params::SegwitHeight

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 96 of file params.h.
