Scaling a Blockchain System from Eventual to Full Atomicity Using Confederation Approach

Abstract

A Blockchain is a decentralized and distributed digital ledger that is used to record transactions and it is secured through cryptographic techniques. It is expected that Blockchain Technology (BCT) will continue to grow exhilaratingly and become indispensable in the architecture of distributed systems. Scaling up BCT is a never-ending race among researchers. When the number of transactions, blocks, or nodes increase, it causes severe scalability problems and stymies the thriving distributed ecosystem. In this paper, the Confederation model is used to make a scalable blockchain system with full atomicity, ensuring that updates are immediately transferred to all nodes, even in cross-zone transactions. The proposed system is flexible and can be easily administered to control network congestion and asymmetric distribution of nodes. The scalability of the proposed system is outperformed as compared to traditional Blockchain.
