Abstract

Blockchain technology innovatively realizes data trusted verification and traceability through the chain structure. But meanwhile, the constant growth of blockchain causes a serious state bloat, becoming a critical challenge restricting the scalability of blockchain. The stateless blockchain, eliminating the necessity of storing the entire state by compressing it into a commitment, is a promising solution to address the state bloat problem. However, current stateless blockchains for unspent transaction output (UTXO) model suffer from poor performance and scalability. In this paper, we present TerseChain, a sharding stateless UTXO-based blockchain that can effectively balance storage, computation, and communication overhead. Specifically, TerseChain innovatively decouples the cross-shard transaction processing into local validation, global ordering, and parallel execution by stateless verification, improving scalability while guaranteeing security. More importantly, our enhanced algorithms markedly increase the efficiency of stateless verification within each shard, necessitating only a constant overhead in storage. Through rigorous theoretical analysis and extensive experimental results, we demonstrate that TerseChain provides high processing capacity that scales favorably with the expansion of the network. TerseChain not only addresses the scalability issues of stateless blockchains but also provides a foundation for AI-enhanced blockchain scalability solutions.

TerseChain：一个无状态的基于utxo的区块链，支持分片

区块链技术创新地通过链式结构实现数据可信验证和可追溯性。但与此同时，区块链的不断增长导致了严重的状态膨胀，成为限制区块链可扩展性的关键挑战。无状态区块链通过将整个状态压缩到一个承诺中，消除了存储整个状态的必要性，是解决状态膨胀问题的一个很有希望的解决方案。然而，目前用于未使用交易输出（UTXO）模型的无状态区块链存在性能和可扩展性差的问题。在本文中，我们提出了TerseChain，这是一种基于无状态utxo的分片区块链，可以有效地平衡存储，计算和通信开销。具体来说，TerseChain创新性地将跨分片事务处理通过无状态验证解耦为本地验证、全局排序和并行执行，在保证安全性的同时提高了可扩展性。更重要的是，我们的增强算法显著提高了每个分片内无状态验证的效率，只需要恒定的存储开销。通过严格的理论分析和广泛的实验结果，我们证明了TerseChain提供了高处理能力，随着网络的扩展而有利地扩展。TerseChain不仅解决了无状态区块链的可扩展性问题，还为ai增强的区块链可扩展性解决方案提供了基础。

期刊介绍： The proposed journal, called the IEEE Transactions on Network Science and Engineering (TNSE), is committed to timely publishing of peer-reviewed technical articles that deal with the theory and applications of network science and the interconnections among the elements in a system that form a network. In particular, the IEEE Transactions on Network Science and Engineering publishes articles on understanding, prediction, and control of structures and behaviors of networks at the fundamental level. The types of networks covered include physical or engineered networks, information networks, biological networks, semantic networks, economic networks, social networks, and ecological networks. Aimed at discovering common principles that govern network structures, network functionalities and behaviors of networks, the journal seeks articles on understanding, prediction, and control of structures and behaviors of networks. Another trans-disciplinary focus of the IEEE Transactions on Network Science and Engineering is the interactions between and co-evolution of different genres of networks.
