IsPreBellatrixVersion returns true if input version is before bellatrix fork.

IsSlashableAttestationData verifies a slashing against the Casper Proof of Stake FFG rules.

IsValidDepositSignature returns whether deposit_data is valid def is_valid_deposit_signature(pubkey: BLSPubkey, withdrawal_credentials: Bytes32, amount: uint64, signature: BLSSignature) -> bool: deposit_message = DepositMessage( pubkey=pubkey, withdrawal_credentials=withdrawal_credentials, amount=amount, ) domain = compute_domain(DOMAIN_DEPOSIT) # Fork-agnostic domain since deposits are valid across forks signing_root = compute_signing_root(deposit_message, domain) return bls.Verify(pubkey, signing_root, signature).

NewGenesisBlock returns the canonical, genesis block for the beacon chain protocol.

ProcessAttestationNoVerifySignature processes the attestation without verifying the attestation signature.

ProcessAttestationsNoVerifySignature applies processing operations to a block's inner attestation records.

ProcessAttesterSlashing processes individual attester slashing.

ProcessAttesterSlashings is one of the operations performed on each processed beacon block to slash attesters based on Casper FFG slashing conditions if any slashable events occurred.

ProcessBlockHeader validates a block by its header.

ProcessBlockHeaderNoVerify validates a block by its header but skips proposer signature verification.

ProcessBLSToExecutionChanges processes a list of BLS Changes and validates them.

ProcessEth1DataInBlock is an operation performed on each beacon block to ensure the ETH1 data votes are processed into the beacon state.

ProcessPayload processes input execution payload using beacon state.

ProcessProposerSlashing processes individual proposer slashing.

ProcessProposerSlashings is one of the operations performed on each processed beacon block to slash proposers based on slashing conditions if any slashable events occurred.

ProcessRandao checks the block proposer's randao commitment and generates a new randao mix to update in the beacon state's latest randao mixes slice.

ProcessRandaoNoVerify generates a new randao mix to update in the beacon state's latest randao mixes slice.

ProcessVoluntaryExits is one of the operations performed on each processed beacon block to determine which validators should exit the state's validator registry.

ProcessWithdrawals processes the validator withdrawals from the provided execution payload into the beacon state.

RandaoSignatureBatch retrieves the relevant randao specific signature batch object from a block and its corresponding state.

SlashableAttesterIndices returns the intersection of attester indices from both attestations in this slashing.

ValidateBLSToExecutionChange validates the execution change message against the state and returns the validator referenced by the message.

ValidatePayload validates if payload is valid versus input beacon state.
