Struct AttestedTransactionEncryptionKey 

pub struct AttestedTransactionEncryptionKey {
    pub scheme: u32,
    pub key_id: Vec<u8>,
    pub public_key: Vec<u8>,
    pub attestations: Vec<ValidatorAttestation>,
    pub next_key: Option<NextTransactionEncryptionKey>,
}

A transaction encryption key exactly as the node served it, before it is trusted.

Deliberately not usable for sealing. Self::verify is the only way to turn it into a TransactionEncryptionKey, so a key served by an untrusted RPC cannot reach the seal path without a validator attestation checking out first.

Fields are kept in their served wire form because the attestation commitment is computed over exactly those bytes.

Fields

scheme: u32

Wire identifier of the key’s IES scheme.

key_id: Vec<u8>

Opaque identifier of the key.

public_key: Vec<u8>

Raw public key bytes.

attestations: Vec<ValidatorAttestation>

Validator attestations over attestation_commitment.

next_key: Option<NextTransactionEncryptionKey>

The next key, when a rotation is scheduled.

Implementations

impl AttestedTransactionEncryptionKey

pub fn verify( self, genesis_commitment: Word, validator_keys: &ValidatorKeys, ) -> Result<TransactionEncryptionKey, RpcError>

Verifies the served key and returns it in usable form.

Requires at least one attestation whose validator key is present in validator_keys – the set committed in a block header this client trusts – and whose signature covers the commitment recomputed from the served fields. Every validator vouches for the same key, so one verifiable attestation from a chain-recognized validator is sufficient.

Errors

Returns an error if the scheme is unsupported, the public key does not decode, or no attestation from a recognized validator verifies.
