  "textContent": "Tendermint and Simplex are both leader-based BFT protocols for partial synchrony with optimal resilience and $3\\delta$ good-case latency. There is a subtle tradeoff between them: In the optimistic responsive model, Simplex obtains a worst-case view latency of $3\\Delta+\\delta$ while Tendermint obtains a worst-case view latency of $4\\Delta+\\delta$. On the other hand, Tendermint requires only a bounded number of certificates to make progress in each view, while in Simplex the number...\n\nBy Ittai Abraham",
