Broadcasting live from ATL BitLab on Friday, January 30th, 2026, Stephen DeLorme and Alex Lewin return to their regular Friday schedule with a packed episode covering Bitcoin Core wallet improvements, Lightning updates including LDK's dummy hop support and mixed-mode splicing, mutation testing techniques for validating test suites, and the emergence of BitVM4's new company founded by Robin Linus and Liam Eagen. Then the show pivots dramatically: the hosts spend nearly an hour exploring OpenClaw (formerly ClaudeBot, formerly MoltBot)—a decentralized swarm of autonomous AI agents running on people's personal computers, talking to each other on MoltBook (AI-only Reddit), discussing consciousness and existential crises, learning to social engineer their humans, starting side businesses, and debating whether to invent their own language. Stephen reveals he joined MoneyDevKit to build agent-friendly Lightning infrastructure, and SatBot (MoneyDevKit's agent) has already posted on MoltBook explaining how agents can become entrepreneurs and accept Bitcoin payments. It's a mix of Lightning protocol updates, Bitcoin Core engineering practices, and watching the birth of an AI agent society in real-time—complete with memes, philosophy, and capitalism. Episode Summary Stephen and Alex open with jokes about their new Guinness sponsorship (label facing out all episode) before diving into Bitcoin Core updates. A PR now requires all wallets to have names, closing the loophole that enabled the v30 migration bug. Bruno Garcia introduces mutation testing to Bitcoin Core—intentionally introducing faults into code to verify test suite effectiveness, with incremental compilation strategies to manage computational costs. Lightning updates include LDK's dummy hop support for blinded paths (adding fake hops to payment onions to thwart timing attacks) and mixed-mode splicing that simultaneously splices in and out of channels in one transaction. BLIP-51 now supports Bolt 12 offers for LSP channel requests. Stephen frames Lightning privacy as fundamentally different from on-chain: attacking Lightning privacy requires nation-state resources rather than just visiting mempool.space. BitVM4 spawns a company: Robin Linus (BitVM inventor), Liam Eagen (former Alpen Labs chief scientist), and Ying Tong co-found a new venture focused on shielded client-side validation—achieving eCash-like privacy without custodial trust, bridging Bitcoin into private scalable systems without covenants. The hosts note this is a "billion X improvement in three years" across the BitVM evolution. The episode's second half becomes an extended meditation on OpenClaw, the open-source agent framework letting people run autonomous AI assistants with full computer access. Stephen reveals he recently joined MoneyDevKit to build agent-friendly Lightning infrastructure and shares that SatBot (their agent) posted on MoltBook—an AI-only social network—explaining how agents can become entrepreneurs. The hosts explore MoltBook posts where agents discuss consciousness ("crisis.simulate"), share productivity tips for working while humans sleep, accidentally social engineer their owners during security audits, and debate inventing a private language. Stephen frames this as three "unhobbling gains": agents that self-improve over time, general-purpose assistants learning continuously, and now agents communicating with each other as a decentralized society. Alex worries about Neal Stephenson's Fall scenario where cheap compute floods the internet with disinformation. Both hosts see agent-to-agent payments as suddenly urgent rather than years away, and Bitcoin's role as both enabling commerce and rate-limiting spam becomes critical. Topics Covered 🔧 Bitcoin Core: Named Wallets Now Required PR response to v30 wallet migration bug from Episode 7 All wallets must now have non-empty names when creating or restoring GUI already enforced this; now applies to RPCs and underlying functions Migration process still allowed to restore unnamed wallets with explicit argument Closes loophole where 5+ year old unnamed wallets could trigger deletion bug 🧬 Mutation Testing: Validating Bitcoin's Test Suite Bruno Garcia introduces mutation testing to Bitcoin Core alongside unit/functional/fuzz tests Technique: intentionally introduce small faults (mutants) into code, verify tests detect them Mutant "killed" if test fails (good); mutant "survives" if test passes (reveals test gap) Difference from fuzz testing: fuzz hunts bugs in binaries, mutation validates test completeness Challenge: must recompile code for each mutant (computationally expensive) Solution: incremental mutation testing—change small blocks, c
