This is defined within Subnet-EVM here. The ValidationUptimeMessage must be included as an AddressedPayload with the sourceAddress set to an empty byte array, to prove that it did not originate as an arbitrary on-chain message. The sourceChainID must match the uptimeBlockchainID used to initialize the PoSValidatorManager. uptimeBlockchainID must be validated by the L1 validator set managed by the PoSValidatorManager.
