Solana presents the Alpenglow protocol to reduce transaction finality to approximately 150 ms.
The new system replaces Proof of History and Tower BFT with Votor and Rotor components.
Alpenglow testing is scheduled for late 2025 and will compete with Ethereum's recently launched Pectra upgrade.
Earlier today, Solana announced Alpenglow, a major protocol update designed to improve transaction speed and network efficiency. Presented by the infrastructure company Anza, a subsidiary of Solana Labs, the new protocol aims to replace Solana's current consensus mechanisms with a redesigned system. But the crypto community is curious: will it be as successful as the ETH Pectra upgrade?
