SwiftShard: Efficient account allocation in blockchain sharding system

Abstract

Sharding technology emerges as a scalable solution for expanding blockchain systems, preserving decentralization and security. Despite its promise, challenges such as costly cross-shard transactions and uneven shard load distribution persist. Prior research aiming to mitigate these issues with dynamic transaction allocation has seen limited success due to substantial overhead and dilution of decentralization and security. Our proposed strategy seeks to diminish cross-shard transactions and balance loads effectively at a lower cost, without sacrificing security or decentralization principles. Utilizing an efficient account allocation algorithm and a dual address mechanism for account management, our findings demonstrate that our framework reduces overhead with competitive performance compared to existing methods.
