The hype is well-deserved. The Automated Reasoning Group is doing some remarkable things. Zelkova[1] is making policy compliance a breeze. And the institutional support for Dafny[2] -- a verification aware programming language -- is bringing program verification to the masses. Really envious of them.

- wiz21c 4y agoThis Dafny thing seems absolutely cool. I didn't check the details but a 30 seconds read tells me that if it could generate rust code (it can Java, C, so it's not unbelievable), then we're in for a better world !
- picardo 4y agoDafny's verification system can be too rigorous for high performance and rapidly changing codebases. S3 team had a paper[1] last year on how they verified ShardStore using a lightweight formal verification system. Since the system was written in Rust, they wrote their verifier in Rust, as well.
