forking

Documentation

Overview

Package forking provides services and DAG wrappers that handle alerts raised when forks are encountered.

When a fork is encountered a forking proof is constructed. The proof consists of two units created by the same process at the same height, and another unit created by the same process, which is the maximal unit created by this process that we can use as a direct parent. This last unit might be nil. This proof is then reliably multicast to all other processes.

When we want to add a unit created by a known forker to our orderer, we need a proof that it is below a unit that someone used as the third unit in their alert. For this purpose we use commitments. Commitments either refer to a raised alert directly by id, or prove that a unit is a predecessor of a unit to which we have a commitment.
