Module polkadot_statement_table::generic

The statement table: generic implementation.

This stores messages other authorities issue about candidates.

These messages are used to create a proposal submitted to a BFT consensus process.

Each parachain is associated with a committee of authorities, who issue statements indicating whether the candidate is valid or invalid. Once a threshold of the committee has signed validity statements, the candidate may be marked includable.
