Tendermint doesn't use Proof of Work (PoW). PoW is hard to test with Jepsen because it only supports probabilistic safety, which means the chain can constantly reorganize. If I'm not mistaken, Jepsen would consider PoW's routine reorgs as linearizeability failures. That said, Jepsen could potentially be modified to support this better, for instance only considering something accepted if its buried X blocks deep.
