An object containing various state info regarding deployments of consensus changes

Fields

bit: u8

determines which bit in the version field of the block is to be used to signal the softfork lock-in and activation. It is chosen from the set {0,1,2,…,28}.

start: EpochNumber

specifies the first epoch in which the bit gains meaning.

timeout: EpochNumber

specifies an epoch at which the miner signaling ends. Once this epoch has been reached, if the softfork has not yet locked_in (excluding this epoch block’s bit state), the deployment is considered failed on all descendants of the block.

min_activation_epoch: EpochNumber

specifies the epoch at which the softfork is allowed to become active.

period: EpochNumber

the length in epochs of the signalling period

threshold: Ratio

the ratio of blocks with the version bit set required to activate the feature

since: EpochNumber

The first epoch which the current state applies

state: DeploymentState

With each epoch and softfork, we associate a deployment state. The possible states are:

• DEFINED is the first state that each softfork starts. The blocks of 0 epoch is by definition in this state for each deployment.
• STARTED for all blocks reach or past the start_epoch.
• LOCKED_IN for one period after the first period with STARTED blocks of which at least threshold has the associated bit set in version.
• ACTIVE for all blocks after the LOCKED_IN period.
• FAILED for all blocks after the timeout_epoch, if LOCKED_IN was not reached.
