More about Alpenglow

The proposal, SIMD 326, has attracted a lot of bullish sentiment from ecosystem participants. 

Mainly, it’s down to Alpenglow’s key technical feature – a consensus mechanism aimed at bringing a 100x speed boost to transaction processing on Solana. If implemented, the upgrade will see Solana’s transaction latency drop from 12 seconds to 150ms.

Alpenglow seeks to achieve this via two consensus aspects – Votor and Rotor.

These will replace the current Proof-of-History and Tower Byzantine Fault Tolerance, or TowerBFT. On the Solana network, Proof-of-History allows for timestamping of transactions to ensure blockchain security and efficiency, while TowerBFT powers the validator process.

The Alpenglow upgrade will activate Votor to slash transaction finality times, replacing TowerBFT. Meanwhile, Rotor is set to replace PoH’s timestamping system, implementing a new data dissemination model that drastically cuts the time nodes take to agree on network status.

Anza, a Solana-focused development firm, unveiled the proposal in May 2025.

While a timeline for mainnet rollout is yet to be announced, the expectation is that as a major protocol upgrade, Alpenglow will catapult Solana to the next level of adoption across payments, trading, and gaming, among other use cases.
