Randamu's most recent innovation is Timevault, a time-lock encryption tool deployed live on the Sui Network (https://timevault.drand.love/) as well as easy to learn and deploy developer libraries for integrating it into other projects: https://github.com/drand/tlock-js

Time-lock encryption has unlocked many new use cases for Web3 distributed networks including sealed bid auctions, verifiable voting for governance, and other similar use cases.
