论文摘要
我们在完整的节点和光线客户合理的环境中对无许可区块链的光线客户进行了系统的研究。在这样的游戏理论模型下，我们设计了一个超级亮点协议，以使客户能够采用一些中继的完整节点（例如两个或一个）来读取区块链。该协议是“通用”，即，可以部署它无视基本共识，而“超级灯”，即光客户端的计算成本以鉴定区块链中的（非）交易的存在变为一个小常数。由于我们的协议解决了扩大区块链技术使用的基本挑战，因此它捕获了各种重要用例，例如多链钱包，DAPP浏览器等。
We conduct a systematic study on the light client of permissionless blockchains, in the setting where the full nodes and the light clients are rational. Under such a game-theoretic model, we design a superlight-client protocol to enable a client to employ some relaying full nodes (e.g. two or one) to read the blockchain. The protocol is "generic", i.e., it can be deployed disregarding the underlying consensuses, and also "superlight", i.e., the computational cost of the light client to predicate the (non)existence of a transaction in the blockchain becomes a small constant. Since our protocol resolves a fundamental challenge of broadening the usage of blockchain technology, it captures a wide variety of important use-cases such as multi-chain wallets, DApp browsers and more.
