Solana's Alpenglow consensus migration is scheduled for Oct. 21 and will remove validator vote transactions from blocks. Co-founder Anatoly Yakovenko says a simpler vote-program change could have halved development time. Validators will pay a flat burned fee per epoch instead of per-vote fees.
Solana co-founder Anatoly Yakovenko said Alpenglow could have shipped in half the time through a simpler vote-program change, just ahead of the Oct. 21 consensus migration. The migration will remove validator vote transactions from blocks. Crypto Briefing reports that more than 90% of validators are ready for the transition.
Vote transactions leave blocks
The Solana Foundation's migration guidance tells explorers and analytics services to reset transaction-count and TPS baselines because vote transactions will disappear from blocks. A total that includes votes will fall even if payments, trades, and other non-vote transactions stay unchanged.
Alpenglow also targets speed. Crypto Briefing says the upgrade reduces finality to approximately 150 milliseconds from the current 12.8 seconds.
Validators pay a flat burned fee
Removing on-chain votes ends fees on individual vote transactions. Each validator instead pays a flat 0.8 SOL admission charge per epoch, and the entire amount is burned.
Payment comes one epoch ahead. The first charge at the start of epoch 1064 covers participation in epoch 1065, and a validator that cannot pay loses permission to vote or produce blocks in the following epoch.
Some nodes may see finality later
Anza's operator documentation qualifies the 150-millisecond finality target. Nodes outside the admitted validator set may receive the result later, learning finality from certificates in a subsequent block.
Anza says that path can add up to one produced-block interval, with longer waits when blocks are skipped or delayed.
