- Solana's Alpenglow Upgrade Reduces Transaction Finality to 150 Milliseconds — this brief
Solana has activated its much-anticipated Alpenglow upgrade, which introduces a new consensus system designed to significantly reduce transaction finality time on the network. The upgrade aims to cut finality from approximately six seconds to just 150 milliseconds by moving validator voting off-chain.
The Alpenglow upgrade also brings changes to the fee structure for validators. It removes the previous system of daily voting fees and replaces it with a fixed validator admission ticket priced at 0.8 SOL per epoch. This change is intended to provide more predictable costs for validators and reduce the overall cost of operating on the network.
The development of the Alpenglow upgrade included extensive testing before its launch, as reported by Crypto Economy. This suggests that the Solana team has taken steps to ensure the upgrade is robust and ready for implementation on the live network.
The upgrade comes at a time when the broader cryptocurrency market is experiencing a period of growth, with the total market cap at $2.86 trillion and 
Bitcoin up 2.28% in the past 24 hours. Solana's native token, SOL, has also seen a 2.25% increase in the same period, reaching a price of $106.38.
The reduction in transaction finality time and the restructuring of validator fees could make Solana more attractive to users and developers, potentially leading to increased adoption of the network. As the upgrade is implemented, it will be important to monitor its impact on network performance and the broader market.
Since this brief published about 45 minutes ago, Solana (SOL) has moved from $106.38 to $106.49 — +0.10%.
