Solana brings Alpenglow to a second public test network, targeting 150 ms finality

Solana’s planned Alpenglow consensus upgrade is now live on both devnet and testnet, giving application teams a place to test before any move on chains handling real funds. Anza, the Solana development company, said on Sept. 25 that the developer network had completed its transition, while testnet had moved over a day earlier. The Solana Foundation’s upgrade page shows Alpenglow activated on both networks. The upgrade is designed to cut transaction finality from about 12.8 seconds to roughly 150 milliseconds. That would reduce the wait time for actions such as releasing deposits after a transaction or letting payment apps tell merchants that a payment has been completed. Alpenglow changes how validators reach consensus on the network record. Instead of embedding votes as transactions inside blocks, validators exchange votes directly, reducing the process to one or two voting rounds. One side effect is that some Solana activity charts may show lower figures, because total transaction counts that include validator votes will fall even if actual payments and transaction volume stay the same.

Solana Moves to Cut Transaction Finality to 150 Milliseconds

Solana is moving forward with the Alpenglow consensus upgrade, which aims to reduce transaction finality time from roughly 12.8 seconds to around 150 milliseconds. The upgrade is expected to activate through Agave 4.3 in October. Co-founder Anatoly Yakovenko says the change is most significant for large-value payments, while ordinary users might not feel much difference. Finality, he explains, is stronger than typical transaction confirmation because it guarantees state changes cannot be undone.

Kaia Advances KaiaBFT Consensus Upgrade: Testnet Hits 10,900 TPS, Targeting Institutional Stablecoins

Kaia (formerly Klaytn) has announced the KaiaBFT consensus upgrade, achieving ~10,900 TPS, 1-second block intervals, and zero transaction failures on its devnet. The performance leap is driven by parallelized consensus and execution, extended execution time windows, and client-side optimizations. Running for over seven years, the public blockchain plans to deploy the upgrade to mainnet in the coming months, prioritizing institutional stablecoin issuance and on-chain financial products.
