Abstract
A single-tier blockchain-based system and method for document transformation and accountability is provided. Transaction documents including document templates relating to a transfer of real property are maintained. Each template includes form elements. The form elements are each associated with a data field identifier and a data value. A data model is maintained for the transaction documents and includes the data field identifiers and the data values for the form elements. A request is received for the transaction documents. The form elements of the transaction documents are automatically populated with the data values via the data model in response to the request. Compliance checking is performed on the data values populating the form elements. A cryptographic hash of the transaction documents is committed to a blockchain copy stored by one or more network nodes in a single-tier when no errors are identified in the data values during the compliance checking.
