Abstract
A method includes, by a first node in a distributed network: 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; accessing a non-interactive proof of inclusion representing membership of the data unit hash within the hash tree; generating a transaction configured to generate a blockchain object including the root hash; and transmitting the transaction and the non-interactive proof of inclusion to a second data node in the distributed network.
