区块链的最后一公里：RPC与节点即服务
Last Mile of Blockchains: RPC and Node-as-a-service
AI总结：
该立场论文调研区块链终端用户访问方式，基于完整性、可用性、隐私性分析轻节点等方案，指出当前满足三属性的最佳访问方式仍是运行全节点，强调未来服务需兼顾这三项要求。
摘要：
尽管大量研究聚焦于保障区块链安全的各类方法，但链上信息需由终端用户访问才能发挥效用。本立场论文调研了终端用户访问区块链的不同方式。我们观察到，在运行全节点与完全使用可信第三方服务这两种极端方案之间，涌现出诸多与轻节点相关的解决方案。我们基于网络通信的三项基本属性——完整性、可用性与隐私性，对这些方案展开分析。研究得出结论：目前，在同时满足这三项属性的前提下访问区块链的最佳方式仍是运行全节点。我们认为，未来构建区块链访问服务时，必须将这三项预期纳入考量。
英文摘要：
While much research focuses on different methods to secure blockchain, information on the chain needs to be accessed by end-users to be useful. This position paper surveys different ways that end-users may access blockchains. We observe that between the two extremes of running a full node and fully utilizing a trusted third-party service, many solutions regarding light nodes are emerging. We analyze these solutions based on three basic properties of web communication: integrity, availability and privacy. We conclude that currently, the best way to access a blockchain while maintaining these three properties is still to run a full node. We consider it essential that future blockchain accessibility services should be built while considering these three expectations.
