Four documents, the same five questions.
No throughput league table and no yield. The cells are what this library is willing to say about the text.
| Question | Practical Byzantine Fault Tolerance |
|---|---|
| What the text proposes | The paper that made a Byzantine quorum practical: a known set of replicas, three phases, and a view change when the leader is useless. Tendermint and HotStuff inherit the shape. Open membership is a different problem. |
| Who may write | Miguel Castro and Barbara Liskov |
| What is settled | Safety if fewer than one third of replicas are faulty. |
| Load-bearing assumption | A permissioned quorum is not a public chain. Citing PBFT does not make a validator set open. |
| What this library says afterwards | Liveness still needs some period when messages get through. Safety does not. |
