Expand description

A GRANDPA justification for block finality, it includes a commit message and an ancestry proof including all headers routing all precommit target blocks to the commit target block. Due to the current voting strategy the precommit targets should be the same as the commit target, since honest voters don’t vote past authority set change blocks.

This is meant to be stored in the db and passed around the network to other nodes, and are used by syncing nodes to prove authority set handoffs.
