Solana sets Oct. 21 for Alpenglow upgrade targeting 150-millisecond finality

Solana has scheduled its Alpenglow upgrade for October 21, which aims to achieve 150-millisecond transaction finality by replacing the existing validator voting system and removing vote transactions from blocks. This could significantly improve network performance and scalability, making Solana more competitive with other high-throughput blockchains. Traders may view the upgrade as a positive catalyst for SOL, though the actual impact on user activity and transaction counts remains uncertain.
