近年来，人们对构建基于区块链的去中心化应用程序（DApps）越来越感兴趣。由于编写区块链智能合约的成本和高延迟，开发dapp面临许多挑战。我们提出了WedgeBlock，一个安全的dapp数据记录基础设施。WedgeBlock的设计降低了dapp的性能和货币成本，其主要技术创新被称为惰性最小信任（LMT）。LMT结合了以下特点：(1)off-chain存储组件；(2)它惰性地写入数据摘要而不是链上的所有数据，以最大限度地降低成本；(3)它集成了信任机制，以确保Offchain Node检测和惩罚恶意行为。我们的实验表明，WedgeBlock比直接在链上写入的基准解决方案快1470倍，便宜310倍。
Over the recent years, there has been a growing interest in building blockchain-based decentralized applications (DApps). Developing DApps faces many challenges due to the cost and high-latency of writing to a blockchain smart contract. We pro-pose WedgeBlock , a secure data logging infrastructure for DApps. WedgeBlock ’s design reduces the performance and monetary cost of DApps with its main technical innovation called lazy-minimum trust (LMT). LMT combines the following features: (1) off-chain storage component, (2) it lazily writes digests of data—rather than all data—on-chain to minimize costs, and (3) it integrates a trust mechanism to ensure the detection and punishment of malicious acts by the Offchain Node . Our experiments show that WedgeBlock is up to 1470× faster and 310× cheaper than a baseline solution of writing directly on chain.
