SUMMARY:Abhishek Singh: WedgeBlock - An Off-Chain Secure Logging Platform for Blockchain Applications
DESCRIPTION:Abstract\n\n\nIn recent years\, there has been a growing interest in building blockchain-based decentralized applications (DApps). DApps typically consist of two components: an on-chain component that implements the logic of the application and runs on blockchain as a smart contract\, and an off-chain component that runs on a regular server to receive and process user requests while coordinating with the on-chain component. Developing DApps faces many challenges due to the cost and high latency of writing to a blockchain smart contract. In addition to the cost and latency\, DApps also face security challenges in maintaining logs and other data. \nWe propose WedgeBlock\, a secure data logging infrastructure for DApps. Logging is one of the most essential building blocks of data management systems and applications. Thus we envision that WedgeBlock would be used as a foundation to implement various DApps. WedgeBlock’s design reduces the performance and monetary cost of DApps with its main technical innovation called lazy-minimum trust (LMT). In LMT\, we show that we can combine the following features in one design: (1) it has an off-chain component for storage\, (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 performed by the Offchain Node.\n\nSpeaker Bio\n\nAbhishek Singh is a 5th-year PhD student in the Computer Science Department at UC Irvine. His current research interests include transaction processing in decentralized data management systems.
