1/ Liveness is an important concept in the Interchain Stack, affecting operational reliability, scalability, and performance.
Yet, the inherent challenges of decentralized blockchain development make it challenging to provide liveness guarantees at the protocol level today.

9/10 In summary, Tendermint is classified as optimistically responsive, meaning it performs well under favorable conditions, but its speed is limited when faced with faulty leaders or network asynchrony (a standard assumption).

10/10 We hope you've found this thread helpful. Make sure you follow @cometbft for future announcements.
Like & Repost the quote below, thanks for your support!
1/10 🧵 In the past we wrote about responsiveness in consensus algorithms and why it's a critical property.
Despite its popularity, questions persist about the responsiveness of the Tendermint consensus algorithm.
For everyone in doubt 👇
