Improving the Scalability of Blockchain Based on Trust Practical Byzantine Fault Tolerance Algorithm (tPBFT)

Since Bitcoin's inception, the non-custodial financial and programmable aspects of blockchain technology have garnered significant global attention, akin to other groundbreaking innovations. Blockchain is a transparent and decentralized ledger that prioritizes immutability, transparency, decentralization, and privacy. Its potential extends to large-scale, beneficial applications across various sectors, encompassing healthcare, supply chain management, logistics, the Internet of Things (IoT), and more. Many industrial applications make use of permissioned blockchains. However, blockchain still faces inherent and external challenges. While permissioned blockchains are suitable for many use cases, they do have limitations, especially in terms of scalability and throughput. In this paper, the authors propose implementing the proposed method by Swathi and Venkatesan using tPBFT (trust Practical Byzantine Fault Tolerance) instead of PBFT (Practical Byzantine Fault Tolerance) to improve the scalability and performance of the blockchain. The Hyperledger Fabric framework is conducted for the proposed method within the assessment of scalability, considering varying transaction volumes, and it demonstrates an enhancement in scalability. This work addresses the need for blockchain systems to evolve and adapt to meet the demands of various industries and applications, acknowledging that scalability is a key factor in their success.
