Consensus::Params

Name

Description

DeploymentHeight

Returns the activation height of a buried deployment.

DifficultyAdjustmentInterval

Returns the number of blocks in one difficulty retargeting interval.

PowTargetSpacing

Returns the target spacing between blocks.

Name

Description

BIP34Hash

Hash of the block at which BIP34 becomes active.

BIP34Height

Block height and hash at which BIP34 becomes active

BIP65Height

Block height at which BIP65 becomes active

BIP66Height

Block height at which BIP66 becomes active

CSVHeight

Block height at which CSV (BIP68, BIP112 and BIP113) becomes active

MinBIP9WarningHeight

Don't warn about unknown BIP 9 activations below this height. This prevents us from warning about the CSV, segwit and taproot activations.

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.

defaultAssumeValid

By default assume that the signatures in ancestors of this block are valid

enforce_BIP94

Enforce BIP94 timewarp attack mitigation. On testnet4 this also enforces the block storm mitigation.

fPowAllowMinDifficultyBlocks

If true, allow minimum‐difficulty blocks after a long gap (used on test chains).

fPowNoRetargeting

If true, disable difficulty retargeting (used on the regression test chain).

hashGenesisBlock

Hash of the genesis block for this chain.

nMinimumChainWork

The best chain should have at least this much work

nPowTargetSpacing

Target spacing between blocks, in seconds.

nPowTargetTimespan

Length of a difficulty retargeting window, in seconds.

nSubsidyHalvingInterval

Number of blocks between successive halvings of the block subsidy.

powLimit

Proof of work parameters

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.

signet_blocks

If true, witness commitments contain a payload equal to a Bitcoin Script solution to the signet challenge. See BIP325.

signet_challenge

Bitcoin Script challenge that signet block witness commitments must solve (BIP325).

vDeployments

Per‐deployment BIP9 version‐bits parameters, indexed by DeploymentPos.

Name

Description

::DeploymentEnabled

Determine if a version‐bits deployment is enabled (can ever be active).

::DeploymentEnabled

Determine if a deployment is enabled (can ever be active)

::PermittedDifficultyTransition

Return false if the proof‐of‐work requirement specified by new_nbits at a given height is not possible, given the proof‐of‐work on the prior block as specified by old_nbits.
