论文摘要
区块链的可扩展性问题之一是增加其大小，这可以防止用户存储它们，从而贡献了分散工作。最近的作品开发了编码区块链的概念，该概念使用户只能存储一些区块链的一些编码片段。但是，该解决方案不受可能传播错误的编码片段的恶意节点的保护。 我们在论文中建议为该系统添加同构哈希。这允许瞬时检测错误的片段，从而避免使用错误的数据解码。我们描述了该机制在编码区块链中的整合，并通过模拟评估了其复杂性。
One of the scalability issues of blockchains is the increase of their sizes which can prevent users from storing them and thus from contributing to the decentralization effort. Recent works developed the concept of coded blockchains, which allow users to store only some coded fragments of the blockchains. However, this solution is not protected against malicious nodes that can propagate erroneous coded fragments. We propose in the paper to add homomorphic hashes to this system. This allows for instantaneous detection of erroneous fragments and thus avoids decoding with wrong data. We describe the integration of this mechanism in coded blockchains and we evaluate its complexity theoretically and by simulation.
