“What we’re actually building is an unstoppable messenger.”

Jeff G & Gigi take a walk in Oslo.

Listen on sovereignengineering.io

In this dialogue:

• Jeff G explains how White Noise started as an attempt to build the most private messenger possible, then slowly mutated into something else: an unstoppable messenger that can survive ugly network conditions and hostile environments
• Why MLS on Nostr is mostly an ordering problem: identity and delivery are the easy parts, group-state evolution is where everything breaks
• Forked histories, missing commits, and the nightmare scenario where a group silently splits into incompatible realities without anybody noticing
• The temptation of coordinators, sequencers, and Pablo’s hilariously named Serial Killer Relay, plus the deeper question of when a relay stops being a relay and quietly becomes a server
• Calle’s Cashu headaches, NIP-60 and NIP-61 edge cases, and the “pocket with a hole” problem where balances seem to disappear, reappear, and generally behave like loose change under a couch
• Jeff G’s current bet for Marmot: a deterministic state machine, tunable convergence rules, and automatic re-init flows that make occasional desync tolerable
• Why large-group privacy degrades fast, and why “perfect privacy” stops meaning much once a chat has hundreds or thousands of people in it
• Why Pika felt more reliable than NIP-17 for one-to-one chats, and where simple tools still beat more ambitious systems
• The White Noise v2 direction: replaceable key packages, smaller app components, and decoupling Nostr identity from the transport layer so relays become just one option among many
• How FIPS pushed the design forward by making transport agility feel real: relays, Wi-Fi, Bluetooth Direct, and whatever else can move packets when the normal internet is gone
• BitChat as a useful proof that narrow, situational tools matter, especially when the internet is overloaded, absent, or simply the wrong abstraction for the problem
• Other experiments blooming around the edges: Tubestr as a weirdly great MLS-backed permission system, plus gaming demos, new clients, and other signs that the building blocks are escaping the original chat use case
• OpenClaw, Fabian’s OpenClaw NIP-17 plugin, and why cryptographic identities make one-agent-per-project workflows feel native
• Jeff G’s current AI workflow: multiple agents, multiple boxes, very little hand-written code, and a strong belief that the implementation middle is collapsing while architecture, taste, and judgment matter more than ever
• Why “build it right” is getting harder to teach and more important to teach, because now you can vibe a terrible idea into existence in an afternoon just as easily as a good one
• Apprenticeship, elders, and why people like Johnathan Corgan matter: some engineering instincts only show up after you have lived through brittle systems, bad assumptions, and real adversaries
• Notification servers that should know almost nothing, the coming KYC of the internet, and the broader goal of building systems with less data to seize and fewer chokepoints to attack
• The argument over easy abstractions at the edge of Nostr, from “Coinbase for Nostr” worries to the closing detour on onchain zaps and second-order effects. For more on that last part, see Gigi’s rebuttal, Careful, Icarus
