unsafe_signer_recv: Receiver<Address>

A Receiver to monitor changes to the unsafe block signer.

blocks_v1_topic: IdentTopic

The libp2p topic for pre Canyon/Shangai blocks.

blocks_v2_topic: IdentTopic

The libp2p topic for Canyon/Delta blocks.

blocks_v3_topic: IdentTopic

The libp2p topic for Ecotone V3 blocks.

Implementations

impl BlockHandler

pub fn new( chain_id: u64, unsafe_recv: Receiver<Address>, ) -> (Self, Receiver<ExecutionPayload>)

Creates a new BlockHandler and opens a channel

pub fn block_valid(&self, envelope: &OpNetworkPayloadEnvelope) -> bool

Determines if a block is valid.

True if the block is less than 1 minute old, and correctly signed by the unsafe block signer.
