Solana will launch on Wednesday Alpenglow upgrade, with transaction finality expected to be reduced to 150 milliseconds

BlockBeats reports that,October 21，Solana will October 21 launch the Alpenglow upgrade, one of the network's largest underlying overhauls since 2020 years. The upgrade will replace the existing validator voting mechanism, aiming to reduce transaction finality from approximately 6 seconds currently to 150 milliseconds, representing an approximately 40-fold increase in speed.

At the core of the upgrade is moving validator voting from on-chain to off-chain and consolidating votes into certificates, enabling transactions to achieve finality in – rounds of consensus. If mainnet performance meets expectations,Solana transaction confirmation speeds will approach the experience of credit-card payments or centralized trading platforms, helping improve the user experience for memecoin trading, stablecoin payments, and on-chain trading platforms. The upgrade will also reduce validator costs.

Currently, validators must pay approximately 2 SOL in voting fees per day. Following the upgrade, voting fees will be eliminated and replaced by a fixed validator admission fee charged per epoch, with each approximately 24-hour epoch charged 0.8 SOL, with costs expected to decline by approximately 60%. However, the upgrade testing process was not entirely smooth. According to Galaxy Digital, since the testnet was first launched in May, the testnet has been wiped and restarted from scratch 6 times. One migration attempt caused the entire testnet migration to fail and was subsequently rolled back. A later migration ultimately succeeded, paving the way for this mainnet launch.

All of the above issues occurred on the testnet and did not involve risks to real funds. According to the announcement, the upgrade is scheduled to launch at the start of epoch 1064 on Wednesday and complete the switchover at slot 5000 after a transition period of 459,653,000 slots.

Key points

BlockBeats states that Solana will October 21 launch the Alpenglow upgrade.
The report describes this upgrade as Solana one of the network's largest underlying overhauls since 2020 years.
The upgrade aims to reduce transaction finality from approximately 6 seconds to 150 milliseconds, an approximately 40-fold increase in speed.
The upgrade proposes moving validator voting from on-chain to off-chain and consolidating votes into certificates, enabling transactions to achieve finality in – rounds of consensus.
The report states that validators currently pay approximately 2 SOL in voting fees per day; following the upgrade, voting fees are proposed to be eliminated and replaced with a fixed admission fee of 24 per approximately 0.8-hour epoch, with costs expected to decline by approximately SOL. 60%。
According to Galaxy Digital, since the testnet was first launched in May, it has been wiped and restarted from scratch 6 times. One migration failed and was rolled back; a subsequent migration ultimately succeeded.
The report explicitly states that all related issues occurred on the testnet and did not involve risks to real funds.
According to the announcement, the upgrade is scheduled to begin at epoch 1064 on Wednesday and complete the switchover at slot 5000 after a transition period of 459,653,000 slots.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

This upgrade primarily changes how validators vote to confirm transactions: votes are proposed to move off-chain and be aggregated into certificates to reduce the time required to achieve finality, while also adjusting the validator fee structure. The 150 milliseconds, approximately 40-fold speed increase, and approximately 60%cost reduction mentioned in the article are targets or expected outcomes, not mainnet results already demonstrated by the material.

Why it matters to readers

If mainnet performance meets expectations, shorter finality times may improve the user experience for memecoin trading, stablecoin payments, and on-chain trading platforms; validators' voting-related costs may also decline.

For beginners, a shorter finality time generally means that a transaction reaches a state that cannot easily be changed more quickly. However, this material describes an upgrade plan and its targets; the actual user experience still depends on mainnet performance.

Risks and unknowns

The materials do not provide direct evidence that the upgrade has been initiated or that the transition has been completed.
Whether the mainnet can achieve 150 milliseconds of finality remains unconfirmed.
Whether validator costs have actually been reduced by approximately 60% remains unconfirmed.
The testnet experienced 6 restarts, one failed migration, and a rollback; stability during the mainnet transition phase remains unknown.
