System for data archival in a blockchain network and a method thereof
Summary
The USPTO granted patent US12596674B2 to National Payments Corporation of India for a blockchain data archival system. The invention enables archiver nodes and non-archiver nodes to maintain, query, and retrieve transaction data across a distributed blockchain network using specialized archival ledgers and data management modules.
What changed
The USPTO issued patent US12596674B2 for a system enabling data archival in blockchain networks. The system categorizes participating nodes as archiver nodes (maintaining complete transaction databases) or non-archiver nodes (maintaining partial archival ledgers), with a data management module that determines whether queried blocks have been discarded and retrieves transaction data accordingly.
For technology companies and blockchain developers, this patent grant establishes exclusive intellectual property rights for National Payments Corporation of India in the area of blockchain data archival and retrieval methods. The patent covers specific mechanisms for handling transaction queries across heterogeneous node types in distributed ledger systems, which may inform product development and technology licensing considerations.

Abstract
The present invention envisages a system (100) for data archival in a blockchain network (20). The blockchain network (20) comprises a plurality of participating nodes, each categorized either as an archiver node (A1-A3) or a non-archiver node (N1-N3). The archiver nodes (A1-A3) maintain a database (102) comprising transaction data corresponding to all block creation events and corresponding transaction IDs. Each of the non-archiver nodes (N1-N3) comprises a data management module (104) which maintains an archival ledger (106a) comprising transaction data corresponding to a partial list of block creation events and corresponding transaction IDs. The data management module (104) receives a request for querying a transaction from a requester-non-archiver node, checks the archival ledger (106a) to determine whether the queried block is discarded or not, and retrieves and returns the transaction data from one of the archival ledger (106a) and the database (102) based on the determination.
