论文摘要
公共区块链应该能够扩展节点数量和交易工作量。区块链可伸缩性三元素已非正式地猜想。这与可伸缩性，安全性和权力下放有关，指出这些方面之一的任何改进都应对至少另一个两者中的至少一项产生负面影响。实际上，尽管进行了大量的研究和实验努力，但所有已知的方法都是折衷的。我们从理论上描述了一种新的区块链体系结构，该架构只要提供了相应的节点的比例增量，该架构将缩放到任意高的工作负载。我们表明，在合理的假设下，我们的方法不需要在安全性或权力下放方面进行权衡。据我们所知，这是考虑区块链所有架构元素的可扩展性，不仅是共识协议的可扩展性，这是反驳三元素的第一个结果。尽管我们的结果目前仅是理论上的，但我们认为我们的方法可能会刺激重大的实际贡献。
Public blockchains should be able to scale with respect to the number of nodes and to the transactions workload. The blockchain scalability trilemma has been informally conjectured. This is related to scalability, security and decentralization, stating that any improvement in one of these aspects should negatively impact on at least one of the other twos. In fact, despite the large research and experimental effort, all known approaches turn out to be tradeoffs. We theoretically describe a new blockchain architecture that scales to arbitrarily high workload provided that a corresponding proportional increment of nodes is provisioned. We show that, under reasonable assumptions, our approach does not require tradeoffs on security or decentralization. To the best of our knowledge, this is the first result that disprove the trilemma considering the scalability of all architectural elements of a blockchain and not only the consensus protocol. While our result is currently only theoretic, we believe that ot our approach may stimulate significant practical contributions.
