Solana cuts transaction finality from 12.8 seconds to 400 milliseconds with Alpenglow upgrade.

Solana, a layer-1 blockchain, recently upgraded its consensus mechanism from TowerBFT to Alpenglow, reducing transaction finality time from about 12.8 seconds to roughly 400 milliseconds. This improvement speeds up transaction confirmation, making transfers nearly instant compared to before. The upgrade also introduced a new voting system called Votor, enhancing network efficiency, though the block propagation rewrite (Rotor) is still pending. With 74.1% of SOL tokens staked and 656 active validators, Solana balances speed with security, but investors should consider the ongoing token issuance rate of 3.59% annually when staking or trading.

Solana's network upgrade is notable for its high staking rate of 74.1%, providing context for readers interested in blockchain technology. For readers following the broader cryptocurrency market, here is Pluang's market snapshot as of Oct 23, 2026 10:21 WIB: out of 50 major cryptocurrencies, 10 rose and 39 fell. Key movers include CRV at Rp6.609 with a 1-day change of -7.37% and a typical hold time of 62 days, SNX at Rp3.845 down 4.73%, and ATOM at Rp32.357 up 4.69%, with respective Pluang order activities showing mostly selling for CRV and ATOM, but balanced buying for SNX.
