 - **TTL** (uint64)
   - A hint for how long (in nanoseconds) the record should be cached before going back to, for instance the DHT, in order to check if it has been updated.
   - Implementations MUST include this value in both `IpnsEntry.ttl` and inside the DAG-CBOR document at `IpnsEntry.data[ttl]`.

 - **Public Key** (bytes)
   - Public key used to sign this record.
     - If public key is small enough to fit in IPNS name (e.g., Ed25519 keys inlined using `identity` multihash), `IpnsEntry.pubKey` field is redundant and MAY be skipped to save space.
