Abstract
A method includes: generating a hash tree representing a structured data object including a data unit, the hash tree including a root hash and a data unit hash representing the data unit; submitting a first transaction to a distributed network, the first transaction configured to generate a blockchain object including the root hash, the blockchain object configured to generate an announcement representing membership of the data unit hash in the hash tree; and submitting a second transaction to the distributed network, the second transaction configured to trigger the blockchain object to generate the announcement based on a proof of inclusion of the data unit hash within the hash tree.
