Member Data Documentation

◆ ALWAYS_ACTIVE

constexpr int64_t Consensus::BIP9Deployment::ALWAYS_ACTIVE = -1
staticconstexpr

Special value for nStartTime indicating that the deployment is always active.

This is useful for testing, as it means tests don't need to deal with the activation process (which takes at least 3 BIP9 intervals). Only tests that specifically test the behaviour during activation cannot use this.

Definition at line 59 of file params.h.

◆ bit

int Consensus::BIP9Deployment::bit

Bit position to select the particular bit in nVersion.

Definition at line 41 of file params.h.

◆ min_activation_height

int Consensus::BIP9Deployment::min_activation_height {0}

If lock in occurs, delay activation until at least this block height.

Note that activation will only occur on a retarget boundary.

Definition at line 50 of file params.h.

◆ NEVER_ACTIVE

constexpr int64_t Consensus::BIP9Deployment::NEVER_ACTIVE = -2
staticconstexpr

Special value for nStartTime indicating that the deployment is never active.

This is useful for integrating the code changes for a new feature prior to deploying it on some or all networks.

Definition at line 64 of file params.h.

◆ NO_TIMEOUT

constexpr int64_t Consensus::BIP9Deployment::NO_TIMEOUT = std::numeric_limits<int64_t>::max()
staticconstexpr

Constant for nTimeout very far in the future.

Definition at line 53 of file params.h.

◆ nStartTime

int64_t Consensus::BIP9Deployment::nStartTime

Start MedianTime for version bits miner confirmation.

Can be a date in the past

Definition at line 43 of file params.h.

◆ nTimeout

int64_t Consensus::BIP9Deployment::nTimeout

Timeout/expiry MedianTime for the deployment attempt.

Definition at line 45 of file params.h.
