1. A method comprising:
obtaining a proximate payload for a proximate chain block for a proximate chain;
hashing, with a hash function, a first identifier of the proximate chain and the proximate payload to generate a second identifier of the proximate chain;
adding the proximate chain block to the proximate chain, wherein the proximate chain block comprises the first identifier, the second identifier, and the proximate payload;
transmitting a request to add the second identifier to a reporting chain; and
receiving a response indicating that the second identifier, incorporated into the proximate chain without using a consensus mechanism, is incorporated into the reporting chain using the consensus mechanism.
