* A record of the proof key a node had in a particular address book. Necessary to keep at each point history so that nodes can verify the correct key was used to sign in transitions starting from the current address book; no matter how keys have been rotated from the time the address book was created.

Used in: LedgerIdPublicationTransactionBody

• uint64 node_id = 1

  * The node id.

• uint64 weight = 2

  * The node's consensus weight when the ledger id was published.

• bytes history_proof_key = 3

  * The public key the node used to contribute to history proofs when the ledger id was published.

* A system initiated transaction to externalize the ledger id and verification key for recursive chain-of-trust proofs extending from the new ledger id. This transaction SHALL be issued whenever the ledger id changes.<br/> This transaction MUST NOT be sent by a client and SHALL be rejected if received by any node.<br/> This transaction SHALL be present in the record stream or block stream. ### Block Stream Effects None

Used in: proto.TransactionBody

• bytes ledger_id = 1

  * The new ledger id.

• bytes history_proof_verification_key = 2

  * The key to use when verifying recursive chain-of-trust proofs that extend from this ledger id.

• repeated LedgerIdNodeContribution node_contributions = 3

  * The node-specific contributions made to the new ledger id.
