论文摘要
本文回顾并强调了如何使用编码方案来解决区块链系统中的各种问题。具体而言，这些问题与扩展区块链有关数据存储，计算和通信成本以及安全性有关。为此，本文考虑了使用编码的块或碎片的使用，这些块或碎片使参与者只能存储总区块链的一小部分，防止因节点留下区块链系统而导致的恶意节点或擦除，从而确保数据可用性，以促进透明度，并扩大碎片块链的安全性。此外，它有助于降低传播块时的沟通成本，这对于引导新节点至关重要，并有助于加快块的共识。对于每个类别的解决方案，我们强调了促使其设计和编码使用的问题。此外，我们对它们的存储，通信和计算成本进行定性分析。
This paper reviews and highlights how coding schemes have been used to solve various problems in blockchain systems. Specifically, these problems relate to scaling blockchains in terms of their data storage, computation and communication cost, as well as security. To this end, this paper considers the use of coded blocks or shards that allows participants to store only a fraction of the total blockchain, protect against malicious nodes or erasures due to nodes leaving a blockchain system, ensure data availability in order to promote transparency, and scale the security of sharded blockchains. Further, it helps reduce communication cost when disseminating blocks, which is critical to bootstrapping new nodes and helps speed up consensus of blocks. For each category of solutions, we highlight problems and issues that motivated their designs and use of coding. Moreover, we provide a qualitative analysis of their storage, communication and computation cost.
