Solana is rewriting its core. 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 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. ------------------------------------------------ Timestamps: 0:00 Intro: digital intelligence needs digital institutions 0:30 AlpenGlow overview + guests from Anza 1:24 Origin story: from “how to halt Solana” paper to building AlpenGlow 5:24 What was limited in TowerBFT/PoH: equivocation + why Turbine doesn’t fully solve it 7:48 The “20% Byzantine + 20% crash-fault” security model (and why) 10:39 The new stack: Rotor (propagation) + Voter (consensus) replaces PoH/gossip/tower 11:47 Rotor deep dive: blocks → slices → shreds + relays + erasure coding 22:03 Voter deep dive: yes/no voting, certificates, and skipping bad leaders fast 30:16 Fast vs slow path finality: 80% yes vs 2-round completion (and why both can win) 34:51 Validator economics + RPC implications: votes off-chain, VAT/fee, smaller ledger footprint 45:55 RPC/WebSocket implications: first-class participation vs second-hand data 47:21 Replacing “global clock” semantics for apps that relied on PoH time 49:20 Migration planning: testnets, coordination, and switching safely

Most of CT treats consensus protocols as boring and impenetrable. That’s a mistake. Under the hood, there’s an intense race to design faster, higher-throughput, and adversary-resilient consensus protocols. This work directly determines retail UX and explains why Ethereum, Solana, and other L1s obsess over consensus. For Episode 1 of TheCoordinate, I sat down with Kartik Nayak (Kartik Nayak), one of the world’s leading consensus researchers, to pull consensus out of the black box and build a first-principles mental model: how consensus actually works, how it evolved over 50 years, how today’s sprawling protocol families fit together, and what the next frontier of consensus research looks like. This is Episode 1 of TheCoordinate. Hope you enjoy it.

Ethereum’s endgame is getting rebuilt, not upgraded. With Lean Consensus (née Beamchain), Ethereum is starting from the endgame: cleaning up technical debt, pushing toward fast finality and preparing for a post-quantum future. It’s one of the most ambitious protocol workstreams for Ethereum and for crypto infrastructure overall. I had a conversation with Justin Drake to understand what Lean Ethereum really is in terms of: real-time proving, the path to higher L1 throughput and what it unlocks for rollups. Stay tuned for the full episode of TheCoordinate podcast!

AI makes intelligence digital. Crypto makes institutions digital. And if intelligence is becoming software, it’s going to need institutions that are software too. That intersection is where I’ve been spending most of my time, trying to understand, in the details, how these systems actually work: how consensus holds up, how markets are designed, how governance behaves under pressure, where privacy fits, and what tradeoffs all of it forces. But most conversation in the ecosystem stays at the level of narratives. The mechanism stays implicit. And if we’re serious about building institutions for digital intelligence, we can’t treat design like a black box. So I’m launching TheCoordinate, a long-form podcast with the researchers and builders pushing the frontier where blockchain and AI meet. Some have shaped major systems. Some wrote foundational papers. All of them are expanding what’s possible at the intersection of intelligence and institutions. The format is simple: each episode I pick a topic, do the homework (read the papers, study the systems), then sit down with the people doing the work and ask the real questions, especially the parts I’m genuinely confused about, until we can build a clear mental model. If you want rigorous conversations about how digital intelligence and digital institutions can co-evolve, subscribe to TheCoordinate. First episode tomorrow. 🎙️🔜
