论文摘要
问责制，可证明违反协议的能力，成为了对销售证明证明（POS）协议安全的主要经济论点。 Rollups是最流行的区块链缩放解决方案，通常使用POS协议作为其母链。我们为汇总定义了责任制，并提出了一项攻击，该攻击表明对现有设计没有问责制。我们提供了负责任的汇总设计并证明其安全性，包括传统的“所谓的”汇总和主权汇总，这是一种基于懒惰的区块链建立的新兴替代方案，仅负责订购和可用汇总数据。
Accountability, the ability to provably identify protocol violators, gained prominence as the main economic argument for the security of proof-of-stake (PoS) protocols. Rollups, the most popular scaling solution for blockchains, typically use PoS protocols as their parent chain. We define accountability for rollups, and present an attack that shows the absence of accountability on existing designs. We provide an accountable rollup design and prove its security, both for the traditional `enshrined' rollups and for sovereign rollups, an emergent alternative built on lazy blockchains, tasked only with ordering and availability of the rollup data.
