摘要

侧链技术增强了区块链的可扩展性和互操作性，使包装数字资产的分散交换和跨链操作成为可能。然而，现有的PoW侧链面临着挑战，包括集中化、高通信成本和基于PoW的不完整的安全证明。本文介绍了一种安全灵活的工作量证明侧链$\mathtt{SFPoW}$，用于包装资产的跨链互操作性。$\mathtt{SFPoW}$促进了几乎所有基于PoW的加密货币的分散资产转移和令牌交换，而不需要软分叉或硬分叉或固定的PoW目标。它在侧链内建立了一个去中心化、公平的验证集，提高了适应性，减少了竞争和确认周期。提出了一种可插拔的跨链证明生成方法，有效地过滤懒惰节点，激励积极参与，并将链上验证开销最小化到200.5字节的证明大小。通过挖掘行为分析和密码约简，$\mathtt{SFPoW}$满足弱原子性和强原子性。在Ronin区块链和以太坊测试网络上的实验表明，往返成本为6.55美元，延迟为372.1-382.6秒，验证了其实用性和效率。

$\mathtt{SFPoW}$SFPoW: Constructing Secure and Flexible Proof-of-Work Sidechains for Cross-Chain Interoperability With Wrapped Assets

Sidechain techniques enhance blockchain scalability and interoperability, enabling decentralized exchanges and cross-chain operations for wrapped digital assets. However, existing PoW sidechains face challenges, including centralization, high communication costs, and incomplete PoW-based security proofs. This paper introduces

$\mathtt{SFPoW}$

facilitates decentralized asset transfers and token swaps across nearly all PoW-based cryptocurrencies without requiring soft or hard forks or fixed PoW targets. It establishes a decentralized, fair validation set within the sidechain, improving adaptability and reducing competition and confirmation periods. A pluggable cross-chain proof generation method is proposed, effectively filtering lazy nodes, incentivizing active participation, and minimizing on-chain verification overhead to a proof size of 200.5 bytes. Through mining behavior analysis and cryptographic reductions,

satisfies weak and strong atomicity. Experiments on the Ronin blockchain and an Ethereum testnet demonstrate a round-trip cost of $6.55 and latency of 372.1–382.6 seconds, confirming its practicality and efficiency.
