Expand description

Consensus is a protocol that chooses canonical chain.

Required Methods§

fn validate_body_against_header( &self, body: &B, header: &SealedHeader<H>, ) -> Result<(), ConsensusError>

Ensures that body field values match the header.

fn validate_block_pre_execution( &self, block: &SealedBlock<H, B>, ) -> Result<(), ConsensusError>

Validate a block disregarding world state, i.e. things that can be checked before sender recovery and execution.

See the Yellow Paper sections 4.3.2 “Holistic Validity”, 4.3.4 “Block Header Validity”, and 11.1 “Ommer Validation”.

This should not be called for the genesis block.

Note: validating blocks does not include other validations of the Consensus

fn validate_block_post_execution( &self, block: &BlockWithSenders, input: PostExecutionInput<'_>, ) -> Result<(), ConsensusError>

Validate a block considering world state, i.e. things that can not be checked before execution.

See the Yellow Paper sections 4.3.2 “Holistic Validity”.

Note: validating blocks does not include other validations of the Consensus
