论文摘要
当前的区块链技术提供了非常有限的互操作性方法。特别是，使区块链能够验证其他区块链上存在数据的解决方案要么非常昂贵，要么未完全分散。为了克服这些局限性，我们引入了Testimonium，这是一种新型区块链继电计划，该方案采用了按需验证的模式和链上执行简化的付款验证，以允许跨区块链的数据验证，同时保持完全分散。评估基于以太坊的区块链的方案表明，与现有解决方案相比，证明书的成本降低了92％。因此，该方案为通用区块链互操作性奠定了坚实的基础。例如，它可以开发用于跨区块链的分布式交易的原子信号协议。
Current blockchain technologies provide very limited means of interoperability. In particular, solutions enabling blockchains to verify the existence of data on other blockchains are either very costly or are not fully decentralized. To overcome these limitations, we introduce Testimonium, a novel blockchain relay scheme that applies a validation-on-demand pattern and the on-chain execution of Simplified Payment Verifications to enable the verification of data across blockchains while remaining fully decentralized. Evaluating the scheme for Ethereum-based blockchains shows that Testimonium achieves a cost reduction of up to 92% over existing solutions. As such, the scheme lays a strong foundation for generic blockchain interoperability. For instance, it enables the development of an atomic-commit protocol for distributed transactions across blockchains.
