Abstract
A multi-tier blockchain-based method for document transformation and accountability is provided. A set of transaction documents for transfer of real property is received. At least a portion of the transaction documents is processed by providing the transaction documents to a tier of supernodes and selecting one of the supernodes. The transaction documents are added via the selected supernode to a blockchain maintained by each supernode. An immutable record of the transaction documents is transmitted from the selected supernode to a different tier of network nodes. One of the network nodes is identified to commit the immutable record of the transaction documents to a blockchain of the different tier. The immutable record of the transaction documents is committed to copies of the blockchain stored by the other network nodes.
