Solana Alpenglow Consensus Upgrade Reaches Live Testing: 150ms Finality in Sight

Alpenglow addresses Solana's core architectural limitation by reducing finality from 12.8 seconds to 150ms and freeing 75% of block space currently used for internal coordination. This structural improvement positions Solana to compete more effectively with alternative blockchains on throughput and user experience. With near-universal validator support and successful test-cluster activation, the upgrade represents a technically credible solution to recent network headwinds.
