Struct EthereumState 

pub struct EthereumState {
    pub last_signed_block_slot: Option<u64>,
    pub block_signing_roots: BTreeMap<u64, [u8; 32]>,
    pub highest_source_epoch: u64,
    pub highest_target_epoch: u64,
    pub attestation_history: AttestationHistory,
}

Ethereum-specific validator state

This is the existing ValidatorState fields extracted for multi-chain support.

Fields

last_signed_block_slot: Option<u64>

Highest slot for which a block was signed

block_signing_roots: BTreeMap<u64, [u8; 32]>

Map of slot -> signing_root for block proposals Used to allow idempotent re-signing of the same block

highest_source_epoch: u64

Highest source epoch in any signed attestation

highest_target_epoch: u64

Highest target epoch in any signed attestation

attestation_history: AttestationHistory

Attestation history for surround vote detection

Implementations

impl EthereumState

pub fn new() -> Self

Create a new empty Ethereum state

pub fn get_block_signing_root(&self, slot: u64) -> Option<&[u8; 32]>

Get the signing root for a block at the given slot, if any

pub fn record_block_signing(&mut self, slot: u64, signing_root: [u8; 32])

Record that a block was signed for the given slot

pub fn get_attestation_signing_root( &self, source_epoch: u64, target_epoch: u64, ) -> Option<&[u8; 32]>

Get the signing root for an attestation with the given source/target, if any

pub fn record_attestation_signing( &mut self, source_epoch: u64, target_epoch: u64, signing_root: [u8; 32], )

Record that an attestation was signed

pub fn prune(&mut self, min_slot: u64, min_epoch: u64)

Prune old entries to limit memory usage
