There’s Tendermint: https://tendermint.com/, which is gaining popularity in distributed systems projects. It’s Byzantine fault tolerant, unlike Raft and Paxos.
Raft is not designed for adversarial use; while it is fault-tolerant, it is not Byzantine fault tolerant. Raft (or Paxos et al) are better suited for wholly-owned distributed databases, where a BFT consensus algorithm like Tendermint would usually be inappropriate because of the overhead of cryptographic operations. If you think a large number of your nodes might get hacked, though, you may want a blockchain anyways :)
No, Tendermint is not useful where Raft is. This is such a crass category error it makes me wonder what your actual skillset is.
