Latencies

Abacus block finality latency configuration.
Validators must wait a certain number of blocks to be mined before they are considered valid and reorg-safe. Without this, validators could be slashed since they may have signed a checkpoint that is no longer valid.
Refer to the following sections for block finality configuration used by the Abacus Works validators.
