An Efficient Bandwidth Based on the Cryptographic Technique of the RSA Accumulator in Block Chain Networks

Blockchain technology is a cryptographic technique that enables users to maintain their data in a decentralized way in a non-editable form without an arbitrator. Data integrity is a significant challenge in blockchain systems. Increasing connectivity will substantially increase the bandwidth and time complexity used by the transaction dissemination or authentication protocol in the blockchain using the Merkle tree, making it prohibitively expensive to operate a full node. The primary goal of this paper is to propose and compare a new transaction authentication technique based on the cryptographic RSA accumulator (ACC) model to the Merkle tree. A proposed ACC model for transaction authentication and proofing has effectively delivered all simulation tests and provided better performance than Merkle tree-SHA256 and Merkle tree-BLAKE256 in blockchain networks.
