alt Hacker Newsetcd has had numerous liveness and safety bugs, with one happening as recently as December of 2025. Would you consider that a correct implementation?
You may be interested in knowing that the largest managed Kubernetes service in the world (AWS EKS) ripped out etcd for in favor of their homegrown consensus service for large scale EKS clusters: https://aws.amazon.com/blogs/containers/under-the-hood-amazo...

Sorry to pile on, but yeah, I wanted to use etcd during 2021 and 2022, around v3.5, but etcd had serious issues including silent data corruption. If you are curious, ask gemini flash "there were a number of etcd releases years ago where it seems a new wave of developers came in and started breaking everything"
I'd like to know what you base your statement on that the Raft implementations in etcd or CockroachDB are incorrect. Your original paper does not mention those implementations, so where does that claim come from?
etcd is some of the most amateur code I've ever seen, despite being one of the oldest and presumably most mature "infrastructure" projects written in Go.
goBGP is arguably even worse.
I don't have a third place in mind that's even worth mentioning relative to these two.
