Summary

Anja proposed the possibility of replacing Solana's existing system through a new Proof-of-Stake based consensus protocol called Alpenglow.
The Votor engine is said to act as a consensus engine that minimizes network delays and enhances resilience.
With the application of Alpenglow, Solana is explained to secure Web2-level responsiveness and finalize blocks within 150 milliseconds.

Attention is drawn to whether a new Proof-of-Stake (PoS) based consensus protocol can emerge from Solana (SOL).

On the 19th (local time), according to the cryptocurrency specialized media Cointelegraph, Solana Labs' subsidiary Anja introduced the new protocol Alpenglow through a blog.

Anja stated about Alpenglow, "It is a protocol that can replace the existing Tower BFT and Proof of History (POH) systems, and it will bring the biggest change in Solana's history."

The engine of Alpenglow consists of Votor and Rotor. First, Votor is a consensus engine that replaces Tower BFT, finalizing a single voting round in one round if 80% of the stake participates, and finalizing the block in two rounds if only 60% of the stake participates. Anja said, "This can minimize network delays and enhance resilience."

Next, Rotor is a data propagation protocol that replaces the existing POH system, maximizing data transmission speed so that all nodes can quickly agree on the network state. This is explained to significantly reduce consensus delays.

Anja explained, "If Alpenglow is applied, Solana can finalize blocks within 150 milliseconds," adding, "This secures a level of responsiveness similar to Web2."
