Hi HN, I built Btfy, an experimental blockchain that uses weather observations as a source of unpredictability for consensus The motivation is simple. Proof of Work generates uncertainty by performing computations. I wanted to explore whether we could obtain some of that uncertainty from the real world instead. Btfy combines weather observation data with a Verifiable Delay Function (VDF): Weather Observation Data -> VDF -> Block -> Hash Chain In the current implementation, observation data is collected from multiple locations, a VDF is computed, and the result is used to generate a block.…

Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
