可互操作区块链的蓝图
A Blueprint for Interoperable Blockchains
摘要：
区块链系统的研究主要集中在提高安全性和弥合区块链和数据库之间的性能差距。尽管有许多有希望的结果，但我们观察到一个令人担忧的趋势，即区块链格局是分散的，其中许多系统存在于孤岛中。除了少数通用区块链（如以太坊或Hyperledger Fabric）外，还有数百种其他专为特定应用程序设计的区块链，它们通常不会相互通信。在本文中，我们描述了我们对可互操作区块链的愿景。我们认为，支持不同区块链之间的交互需要克服超越数据标准化的挑战。根本问题是允许在不同区块链中运行的智能合约进行通信。我们讨论了三个开放的问题：访问控制，一般的跨链事务和跨链通信。我们在文献中描述了这些问题的部分解决方案。最后，我们提出了一种新的设计来克服这些挑战。
英文摘要：
Research in blockchain systems has mainly focused on improving security and bridging the performance gaps between blockchains and databases. Despite many promising results, we observe a worrying trend that the blockchain landscape is fragmented in which many systems exist in silos. Apart from a handful of general-purpose blockchains, such as Ethereum or Hyperledger Fabric, there are hundreds of others designed for specific applications and typically do not talk to each other. In this paper, we describe our vision of interoperable blockchains. We argue that supporting interaction among different blockchains requires overcoming challenges that go beyond data standardization. The underlying problem is to allow smart contracts running in different blockchains to communicate. We discuss three open problems: access control, general cross-chain transactions, and cross-chain communication. We describe partial solutions to some of these problems in the literature. Finally, we propose a novel design to overcome these challenges.
