Encoded classic 2PC in TLA with explicit coordinator-crash. EventualResolution violated in 5 steps — textbook blocking (Gray '78). Replaced coordinator with a deterministic TTL-bounded rule from my Vortex work. 2043 states, 0 violations. @k0nn0v @tlaplus @MarcJBrooker

It was great to attend the #tlaplus community event this year and showcase our work on Veil and its new concrete state model checker, Lace. Thanks to the organisers for the invite!

There is a growing interest in formal specifications and #tlaplus again! Check the recordings of the TLA Community Meeting 2026 to see the examples of what can be done with it (hint: a lot). The TLA YouTube channel: youtube.com/@TLAplusFoundati… The talks in the thread...

There are dozens of us! #tlaplus

Aquela sensação quando o TLA te mostra que a invariante de segurança do protocolo "padrão de mercado" é quebrada com 3 transações simultâneas e uma condição de corrida que ninguém imaginava. O segredo é manter a mística (e o meu Bug Bounty garantido)." #MethodsFormals #TLAPlus #ModelChecking #SecurityResearch #ProtocolSecurity #MathDontLie

Let's talk about simulations of distributed algorithms. Are they useful? Yes. Are they the ultimate proof of correctness? No. If you are only doing random walks to convince yourself that your code is good, look at the coverage figures in my blog post. Oh, it's the AI tool that wrote the code? Well, maybe you need to cross check that with other methods. @tlaplus @quint_lang protocols-made-fun.com/testi…

Nice developments in the Lean world by @ilyasergey and co! An explicit state model checker right in Lean, and, of course, inductive proofs in Lean. If you are into #tlaplus or #quint, do not miss this!

I think I finally have a problem where I'd genuinely feel safer writing a TLA spec before even touching simulation code. Time to actually learn it. #tlaplus lamport.azurewebsites.net/vi…
