abstract = "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 propose 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.",
