Block verification interface

Required Methods

fn verify_concurrent<BCI>( &self, parent_header: &<<Block as GenericOwnedBlock>::Header as GenericOwnedBlockHeader>::Header<'_>, parent_block_mmr_root: &Blake3Hash, header: &<<Block as GenericOwnedBlock>::Header as GenericOwnedBlockHeader>::Header<'_>, body: &<<Block as GenericOwnedBlock>::Body as GenericOwnedBlockBody>::Body<'_>, origin: &BlockOrigin, beacon_chain_info: &BCI, ) -> impl Future<Output = Result<(), BlockVerificationError>> + Send

where BCI: DeriveConsensusParametersChainInfo + ShardMembershipEntropySourceChainInfo,

Verify the provided block header/body, typically as part of the block import, without executing the block.

This method can be called concurrently even for interdependent blocks.

Expects (and doesn’t check) that parent_header corresponds to header’s parent root, header corresponds to body and is internally consistent, see:

• Block::is_internally_consistent()
• BlockHeader::is_internally_consistent()
• BlockBody::is_internally_consistent()

These invariants are not checked during verification.

Since verification doesn’t execute the block, the state root is ignored and needs to be checked separately after/if the block is re-executed.

fn verify_sequential( &self, parent_header: &<<Block as GenericOwnedBlock>::Header as GenericOwnedBlockHeader>::Header<'_>, parent_block_mmr_root: &Blake3Hash, header: &<<Block as GenericOwnedBlock>::Header as GenericOwnedBlockHeader>::Header<'_>, body: &<<Block as GenericOwnedBlock>::Body as GenericOwnedBlockBody>::Body<'_>, origin: &BlockOrigin, ) -> impl Future<Output = Result<ExtraBlockVerificationDetails, BlockVerificationError>> + Send

Complementary to Self::verify_concurrent() that expects the parent block to be already successfully imported.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
