论文摘要
区块链应用的开发增加了对区块链性能的需求。在许多区块链扩展解决方案的尝试中，碎片可以提高性能并减少每个节点的存储要求。碎片增强了整个区块链的吞吐量。大多数碎片解决方案都有固定数量的碎片。我们提出更广泛的链条，并按帐户划分。碎片数量增加到无限。同时，更宽结合了汇总的想法并保留主链以确认子链的状态。该设计可以避免散落到子链的工作计算能力证明，并确保区块链的安全性。
The development of blockchain applications increased the demand for blockchain performance. Among the attempts of many blockchain scale-out solutions, sharding can improve performance and reduce the storage requirements of each node. Sharding enhances the throughput of the entire blockchain. Most sharding solutions have a fixed number of shards. We propose Wider chain with sharding by account. The number of shards is increased to unlimited. Meanwhile, Wider combines the idea of rollup and retains the main chain to confirm the status of the subchains. This design can avoid the Proof of Work computing power being scattered to the subchains and ensure the security of the blockchain.
