News: Alpenglow lands today

- Replaces TowerBFT in epoch 1064, est. ~7:20 AM CDMX
- Finality: ~12.8 s today, ~150 ms target
- Switches at slot 459,653,000 after ~18 min
Why it matters
- Near-instant settlement, e.g. instant point-of-sale confirmation (Solana)
- Merchants and bridges can act on payments sooner (CoinDesk)
- Votes leave blocks: ~1 SOL/epoch vote fees become a flat 0.8 SOL (Solana)
For analysts: votes leave blocks, so TPS drops; expect a ~2-slot gap. Check getAgGenesisCert. More: CoinDesk · Triton guide

Chart of the Week, powered by Allium
Chart: Faster blocks, same user activity
Caption: Solana blocks/day vs non-vote txs/day · Sep 15 – Oct 20 · Allium Explorer
