Struct ValidatorKeyAttestation 

pub struct ValidatorKeyAttestation {
    pub validator_public_key: Vec<u8>,
    pub signature: Vec<u8>,
}

A single validator’s attestation of the transaction encryption key.

Fields

validator_public_key: Vec<u8>

Public key of the attesting validator, encoded using the [miden_serde_utils::Serializable] implementation for [miden_protocol::crypto::dsa::ecdsa_k256_keccak::PublicKey]. Must match a validator signing key committed in block headers to be trusted.

signature: Vec<u8>

The validator’s signature over the attestation commitment: the Poseidon2 byte-mode hash of domain_tag || scheme || len(key_id) || key_id || genesis_commitment || len(public_key) || public_key || next_key_transcript, where domain_tag is the ASCII string MIDEN_TX_ENCRYPTION_KEY_ATTESTATION_V1, the scheme, the rotation block number, and the length prefixes are encoded as 4 bytes little-endian, and the genesis block commitment ties the attestation to one network. next_key_transcript is empty when no rotation is scheduled, or the next key’s scheme || len(key_id) || key_id || len(public_key) || public_key || rotation_block_num otherwise, binding any scheduled rotation to the signature. The canonical construction is miden_node_proto::domain::encryption.
