Solana Prepares for Alpenglow Upgrade, Aiming to Reduce Block Confirmation Time to 150 ms

Solana is preparing validators for the Alpenglow upgrade, which aims to reduce block confirmation time from approximately 12 seconds to around 150 milliseconds. This upgrade will change how validators confirm transactions by combining multiple votes into a single digital certificate, thereby reducing the data the network needs to process. This improvement is expected to enhance transaction capacity, benefiting trading platforms, payment apps, and DeFi services during peak periods. Validators must register new BLS public keys, with the upgrade expected to roll out in stages between August and October 2026, although this timeline may change during testing. Currently, SOL trades near 77 dollars, with a market capitalization of about 45 billion dollars, ranking seventh among cryptocurrencies. The token has dropped 61% over the past year but gained nearly 5% in the last month. The activation window for Alpenglow runs from August to October 2026, contingent on sufficient validator key registrations and the activation of the Validator Admission Ticket (VAT). Analysts note that previous upgrades have sometimes led to increased trading activity, but this trend is not guaranteed.
