Abstract
A multi-tier blockchain-based method for document transformation and accountability is provided. A set of transaction documents for a transfer of real property is received and the transfer is recorded via a multi-tier blockchain. The set of transaction documents is stored on a ledger associated with two or more supernodes in a tier of supernodes. A cryptographic hash of the set of transaction documents is provided to a different tier of nodes and stored on a ledger associated with each of the nodes in the different tier. A number of supernodes in the tier is larger than a number of the nodes in the different tier.
