    Interface ChallengeBinding

    Binding identifies the (purpose, resource, subject) trio the challenge is scoped to. btxd also embeds hashes + anchor info for replay protection.

    interface ChallengeBinding {
        anchor_hash: string;
        anchor_height: number;
        chain: string;
        challenge_id_rule?: string;
        purpose: string;
        resource: string;
        resource_hash: string;
        salt: string;
        seed_derivation_rule?: string;
        subject: string;
        subject_hash: string;
        [k: string]: unknown;
    }
