PVF Pre-checking
⚠️ This runtime API was added in v2.
There are two main runtime APIs to work with PVF pre-checking.
The first runtime API is designed to fetch all PVFs that require pre-checking voting. The PVFs are identified by their code hashes. As soon as the PVF gains required support, the runtime API will not return the PVF anymore.
fn pvfs_require_precheck() -> Vec<ValidationCodeHash>;
The second runtime API is needed to submit the judgement for a PVF, whether it is approved or not. The voting process
uses unsigned transactions. The PvfCheckStatement is circulated through the network via
gossip similar to a normal transaction. At some point the validator will include the statement in the block, where it
will be processed by the runtime. If that was the last vote before gaining the super-majority, this PVF will not be
returned by pvfs_require_precheck anymore.
fn submit_pvf_check_statement(stmt: PvfCheckStatement, signature: ValidatorSignature);
