Data Security Storage Mechanism Based on Blockchain Network

With the rapid development of information technology, blockchain technology has also been deeply impacted. When performing block verification in network, if all transactions are verified on chain, this will cause accumulation data resulting storage problems. At same time, security is challenged, which put enormous pressure block, extremely low communication efficiency block. The traditional system uses Merkle Tree method to store data. While verifying integrity and correctness data, amount proof large, it impossible verify batches. A large greatly impact efficiency, end-to-end delays seriously affect system’s stability, security. In order solve problem, paper proposes replace tree with polynomial commitments, take advantage properties polynomials reduce size consumption. By realizing ingenious use aggregated smart contracts, blocks improved, node reduced.
