Solana’s Latest Network Upgrade Goes Live, Bringing New Benefits to Users

Solana has activated its Alpenglow upgrade, introducing a new consensus system designed to significantly reduce the time needed to finalize transactions. The upgrade aims to make payments and trades settle in around 150 milliseconds, replacing the multi-second delays associated with the previous mechanism.

Transaction finality is the point at which a payment is considered settled, allowing applications to treat it as complete with greater confidence. Under Solana’s former system, validators recorded their votes as blockchain transactions and gathered approvals across successive blocks.

Alpenglow changes this process by allowing validators to communicate their votes directly and combine approvals into certificates. As a result, blocks can reach finality after one or two voting rounds.

The Solana Foundation reported that the transition from the previous system took approximately 900 milliseconds. Of the network’s 654 participating validators, 446 voted to certify the block that established the starting point for the new mechanism. This measurement reflects the system transition rather than the finalization time of individual transactions.

How Alpenglow Could Improve the User Experience

Before the upgrade, many Solana applications displayed transactions as confirmed before the network had fully finalized them. Payments could appear successful almost immediately, even though applications might still need to wait for stronger settlement assurances.

Alpenglow aims to reduce that gap, allowing applications to confirm payments faster while gaining greater confidence that transactions will remain settled.

The change could benefit services that need to release funds or goods as soon as a payment arrives. Cryptocurrency exchanges, for example, could make deposits available for trading sooner. Merchants accepting stablecoins could also verify payments more quickly, reducing waiting times for customers.

However, the speed experienced by users will depend on how individual applications process and receive transaction updates. Anza, the developer behind Solana’s Agave software, told CoinDesk that some computers may receive finality information later than validators directly participating in the voting process.

The 150-millisecond figure is a target under normal network conditions, rather than a guaranteed settlement time for every transaction.

Users can continue using their existing wallets, and the upgrade does not change transaction fees or the standard process for transferring funds. The improvements come from changes to how validators communicate and coordinate their decisions.

Why Solana’s Transaction Counts Could Fall

Alpenglow also changes how validator activity is recorded, potentially affecting the transaction figures shown on blockchain explorers and analytics platforms.

Previously, validator votes appeared as individual on-chain transactions. Under the new mechanism, those votes are no longer recorded in the same way, which could cause reported transaction totals to decline.

Such a drop would not necessarily mean fewer users are making payments or trading on Solana. Instead, it could reflect the removal of validator votes from the transaction count.

To make accurate comparisons across the upgrade, analysts will need to distinguish user-generated payments and trades from the validator votes that previously contributed to reported network activity.
