论文摘要
尽管区块链是比特币和各种加密货币的支持技术，但为众多应用提供了一个潜在的有效框架，但它仍然受到了不可能三角形的不利影响。区块链的性能，安全性和权力下放通常不会与网络中的参与者数量同时扩展。 Li等人最近在碎片区块链中引入了误差校正代码。部分地解决了这三个三元素，在不损害安全性和权力下放的情况下增强了吞吐量。在本文中，我们通过三种方式改进了编码的碎片计划。首先，我们提出了一种新颖的二维碎片策略，该策略固有地支持交叉交易，从而减轻了对复杂碎片间交流协议的需求。其次，我们在块的传播中采用分布式存储技术，从而改善了受限带宽下的延迟。最后，我们结合了低度的多项式加密原始图，这将编码的区块链技术带入了可行的现实世界参数的领域。
Although blockchain, the supporting technology of Bitcoin and various cryptocurrencies, has offered a potentially effective framework for numerous applications, it still suffers from the adverse affects of the impossibility triangle. Performance, security, and decentralization of blockchains normally do not scale simultaneously with the number of participants in the network. The recent introduction of error correcting codes in sharded blockchain by Li et al. partially settles this trilemma, boosting throughput without compromising security and decentralization. In this paper, we improve the coded sharding scheme in three ways. First, we propose a novel 2-Dimensional Sharding strategy, which inherently supports cross-shard transactions, alleviating the need for complicated inter-shard communication protocols. Second, we employ distributed storage techniques in the propagation of blocks, improving latency under restricted bandwidth. Finally, we incorporate polynomial cryptographic primitives of low degree, which brings coded blockchain techniques into the realm of feasible real-world parameters.
