To mark the launch of user-programmable smart contracts on the Filecoin Virtual Machine (FVM), the drand team is excited to release a three-part blog series on using randomness on the FVM! In this first part, we dive into the prevrandao EVM opcode (the FVM fully supports EVM bytecode!), a sample Solidity contract using it, a UI to interact with it, and some other necessary plumbing to make it all work.

🎲 drand & 🛰️ CryptoSat: Pioneering Space-Based Randomness

drand is the next generation distributed randomness service. It requires several independent organizations to run a node that contributes a part of the randomness to the network. So far, all of the nodes that participate in the League of Entropy’s drand network have been placed on Earth. But this has just changed! Temporarily for now, but hopefully more permanently in the near future. Read on to find out all the details.

Monitoring distributed systems is a challenge. While there are established patterns and solutions for monitoring the most common types of applications, there is usually no silver bullet. In this blog post, we outline the challenges that we faced when implementing monitoring for one such system, drand.
