Solana Alpenglow Proposal Enters Voting Stage for Consensus Overhaul
Solana developers are advancing the Alpenglow proposal, now in the validator voting stage. Key points include:
- Over 10% of validators support the upgrade; over 88% have yet to vote.
- The proposal aims to replace Proof-of-History and TowerBFT with two new components: Votor and Rotor.
- Votor reduces transaction finalization time from over 12 seconds to approximately 150 milliseconds.
- Rotor will enhance network efficiency by minimizing data transfer between validators, benefiting high-activity applications like DeFi and gaming.
- The “20+20” resilience model ensures chain operation even with 20% of validators adversarial and another 20% offline.
- The proposal focuses on faster speeds while improving security and fairness for validators.
