Solana Co-Founder Says Industry Is Not Ready for Alpenglow Upgrade
Solana co-founder Anatoly Yakovenko has drawn attention to the network’s upcoming Alpenglow consensus upgrade, saying the industry is “not ready” for what is coming. His remarks followed Alpenglow’s successful migration to Solana’s developer network in late September 2026.
Alpenglow is designed to dramatically reduce Solana’s transaction finality time—from roughly 12.8 seconds to around 150 milliseconds. The upgrade replaces Solana’s existing TowerBFT consensus mechanism with Votor, which allows validators to exchange votes directly and finalize blocks in one or two rounds.
The upgrade is currently being tested on Solana’s public testnet and devnet. Its targeted speed could be particularly relevant for payments, exchanges, bridges and applications requiring near-instant settlement. However, the 150-millisecond figure remains a target, and Alpenglow has not yet been given a confirmed mainnet launch date.
Importantly, Alpenglow changes Solana’s consensus layer rather than transaction execution. According to Solana’s documentation, users will not need to change how they sign or send transactions, while developers whose applications simply send transactions and read account data generally require no migration.
The rollout still involves technical challenges. Validator software needs to support the new protocol, while applications and infrastructure that process Solana’s block data may need adjustments. The upgrade proposal itself also identifies the migration of such a major consensus system as an implementation risk.
