Sourcify: Towards Safer Contract Interaction for Humans

Posted by Edi Sinovčić, Franziska Heintel on June 2, 2020

tl;dr: Building sensible blockchain applications for humans is hard. You can enhance the user experience of your dapp today by leveraging the power of open source. Increase awareness and give more transparency on what users are actually doing when interacting with your code on the blockchain, i.e. when signing a transaction, by publishing the source code to this decentralized repository and using metadata files, which translate “random” hex strings into human-readable language. Sourcify is a tool to help you do exactly that. If you...
