Solana Promises 150-Millisecond Transaction Finality

Alpenglow upgrade is designed to speed up Solana transaction finalization, but its mainnet activation timing is unclear.

Alpenglo's upgrade is designed to reduce Solana's transaction finalization time to around 150 milliseconds; But this figure is still the technical goal of promotion, not a result that has been proven in the main network and real market conditions. According to CoinDesk, the upgrade was activated on Solana's public testnets.

Finalization is when a transaction is no longer considered practically reversible. Reducing this time can reduce the wait for exchanges to confirm a deposit, cross-chain bridges to release assets, and payment programs to complete settlements. Faster speed alone does not guarantee higher SOL prices or increased network usage.

Alpenglo is supposed to replace the current consensus mechanism with a new method. In this model, validators exchange their votes directly with each other, instead of all votes being recorded in blocks like transactions. This change can shorten the time required for an agreement.

A report available on CoinDesk on September 26 said that Alpenglo had been activated on the devnet and testnet, but no specific date had been announced for the move to the mainnet. Also, the targeted speed had not yet been consistently measured in live network conditions.

This distinction is important for users and traders: successful testing on the testnet is not the same as public activation. In addition, the processing time of wallets and the verification policy of each exchange can make the actual deposit and withdrawal experience longer than the finalization time of the network itself.

Reducing transaction finalization time can improve the experience of Solana-based exchanges, bridges, and payments, but the 150ms number is currently a technical goal, not a guarantee of mainnet performance. Traders should check the exchange's upgrade status and notification before withdrawing or depositing. The change in the number of transactions after removing the vote of validators does not necessarily mean a decrease in user activity, in real conditions.
