AuthenticatedValidator

espresso_types::v0::v0_3

Struct AuthenticatedValidator 

Source 
pub struct AuthenticatedValidator<KEY: SignatureKey>(RegisteredValidator<KEY>);
Expand description

Validator eligible for consensus participation. Guaranteed to have valid BLS and Schnorr signatures. This is a newtype wrapper around RegisteredValidator that guarantees authenticated=true.

§0: RegisteredValidator<KEY>

Implementations§

Source§

impl<KEY: SignatureKey> AuthenticatedValidator<KEY>

Source

pub fn into_inner(self) -> RegisteredValidator<KEY>

Source

pub fn ensure_eligible( &self, protocol_version: Version, ) -> Result<(), IneligibleValidator>

Checks that this validator can participate in consensus at protocol_version.

Encodes only protocol-version-gated requirements; stake and delegation checks live in select_active_validator_set.

The contract only checks the port of a p2p address, so the address is also checked with NetAddr::validate: one that fails it cannot be dialed.

§Liveness during the CLIQUENET upgrade transition

The active validator set for epoch N is selected at the epoch root header in epoch N-2, using that root header’s protocol version (see Fetcher::fetch). When CLIQUENET activates at some epoch K, the roots for epochs K and K+1 are pre-CLIQUENET headers, so those active sets were selected without this filter and may include validators missing x25519_key or p2p_addr.

In epochs K and K+1, the cliquenet network silently skips peers without connect info (no panic, no error), but they still count toward the quorum threshold. Liveness through the transition therefore requires the eligible subset of validators to hold >= 2/3 of total active stake. From epoch K+2 onward, roots are post-CLIQUENET and this filter applies.

Operators are warned at startup on the version immediately preceding NEW_PROTOCOL if their on-chain entry is missing network info.
