Episode 3 of TheCoordinate is about one of the most ambitious protocol upgrades in crypto right now: AlpenGlow, a redesign of Solana's consensus + data propagation stack.
I sat down with Roger Wattenhofer, Kobi and Quentin Kniep from Anza Labs to break down:
what was structurally limited in TowerBFT + PoH?
how AlpenGlow works end-to-end: Rotor (erasure-coded dissemination via relays) + Voter (a dance of fast and slow paths)
why they are optimizing for a 20% Byzantine + 20% crash-fault model?
what changes for validators + RPCs when votes move off-chain (VAT/fee mechanics, different cost structure, and a smaller ledger footprint)?
what 100s-of-ms finality means in practice for MEV, remote validators, and upcoming multi-proposer designs?
If you’re building or operating on Solana, this is one of those quiet-but-fundamental stack shifts and you may wanna listen to this episode to learn how this upgrade touches you.
This is Episode 3 of TheCoordinate. Hope you enjoy it.
