Solana Speed Upgrade Nears Mainnet Activation

Solana's major speed upgrade, dubbed Alpenglow, has cleared a critical testing milestone on its public testnet.

The update targets a reduction in transaction finality from roughly 13 seconds to 0.15 seconds and replaces the current TowerBFT consensus mechanism with Votor.

Validators running Agave 4.3 can now test the migration on a live copy of the network without risking real funds, following more than four months of trials on a dedicated test environment.

Mainnet activation is currently penciled in for around September 28.
