Bitcoin soft-fork debates around CTV, CSFS, OP_CAT, and OP_VAULT keep stalling — and Misha Komarov of Allocinit argues you can emulate much of that covenant behavior with cryptography instead of changing consensus.

Misha joins Stephan to unpack Bitcoin PIPEs v2: a Witness Encryption design that locks a signing key under an NP statement so a valid zero-knowledge proof decrypts the key and produces an ordinary Schnorr spend. Bitcoin L1 only checks a normal signature.

They compare PIPEs v1 (Functional Encryption / richer post-covenants) with v2 (Witness Encryption / binary pre-covenants), ciphertext sizes from ~300 TB toward single-digit terabytes, DKG and 1-of-n setup assumptions, non-custodial vault and shared-pool use cases, contrasts with cosigner models like Sigbash, and how Allocinit’s Shielded Bitcoin design differs from Shielded CSV’s client-side validation approach — plus open cryptanalysis challenges and a path toward implementable code.

Almost every public Bitcoin node still runs Bitcoin Core. Brandon Black argues that client monoculture is a systemic risk — and that automation plus AI now make independent consensus implementations more realistic than skeptics assume.

Brandon (aka reardencode) returns to Stephan Livera Podcast for the first episode in a mini-series on non-Core Bitcoin implementations. He is shipping rbitcoin, a Rust full node aimed at server-side wallet and Lightning backends, with Electrum served in-process.

They dig into why rbitcoin has no UTXO set and no Core-style dbcache, how build-time differential testing differs from satd’s in-process libbitcoinconsensus dual-eval, BIP324 v2-only P2P, archival storage tradeoffs, LibreRelay-inspired policy, and what “production-ready” means when every first-party line was written by AI under his prompting.

Brandon is blunt about maturity: the project is still early, contributors are welcome at rbitcoin.org, and listeners should treat alt clients as high-scrutiny infrastructure — not a drop-in replacement for Core tomorrow.

Most Asian markets still make buying and saving Bitcoin painfully hard. James of Ârc argues the fix is not another protocol breakthrough — it is local founders shipping simple DCA and savings products market by market.

James joins me from Mirissa Beach, Sri Lanka, where Arc is partnering with Fulgur Ventures on a continuous Bitcoin accelerator. He is a former EY advisor and Playfair Capital investor who previously built with Alexander Mann (now Fulgur GP) and later sold Consequence, an early LLM-on-databases company.

The conversation covers why the program is continuous rather than a six- or twelve-week cohort, how to apply at arc.lk/Fulgur, why Sri Lanka ranks among his top-three country bets, the South Coast talent melting pot, funding DCA apps across Asia even where operators already exist, AI agents as Bitcoin users, and why Strike expanding should not scare local founders.

Mike Belshe, co-founder and CEO of BitGo, walks through how institutional Bitcoin custody actually works in 2026: qualified custody, self-custody co-signing, and why BitGo still centers a 2-of-3 model after pioneering P2SH multisig in 2013.

BitGo now operates as a US-regulated qualified custodian and public company, while still offering the same wallet stack individuals can run in self-custody mode. The conversation covers what “institutional security” means in practice — HSM-backed co-signing, open-source recovery paths, multi-jurisdictional key storage (including how BitGo moved WBTC when US regulation looked hostile), and why on-chain multisig still beats vendor-locked MPC for cold ops.

They also dig into the political and operational risks around large Bitcoin holdings: KYC and PII as honeypots, France tying names to amounts, the war on cash reaching Bitcoin, and whether an EO 6102-style confiscation risk still belongs in the threat model. On the institutional side, Belshe pushes back on multi-custodian setups that add failure modes, explains insurance limits versus the size of the Bitcoin market, and why splitting wallets matters after events like Bybit.

Walter Maffione, CEO and co-founder of KaleidoSwap, join me to explain how the project grew from an RGB Lightning DEX into a broader swap engine and LSP stack — Lightning as rails between Liquid, Arkade, Taproot Assets, Spark, and RGB — plus KaleidoSDK, desktop app, and browser Extension.

We dig into web app and SDK integrations for merchants and unified-balance wallets, how HTLC atomicity works across layers, BOLT 12 multi-asset offers and Nostr discovery for competing providers, Bitcoin-only scope with Flashnet and Utexo bridges for external stables, and a product lineup of desktop app, browser extension, and dual SDKs.

Walter also covers agentic payments via MCP plugins, self-sovereign local models with Tether’s QVAC, fee ranges around 0.5–1%, and a one-to-three-month mainnet launch path for the extension, swap provider, and web app.

Recent attacks exposed how even large, educated Bitcoin holders remained exposed through single-vendor setups. The core lesson is that self-custody alone does not remove single points of failure; deliberate design is required.

Dhruv Bansal, co-founder and CISO of Unchained, joins to examine these incidents and the practical barriers that keep most hardware wallet users on single sig despite years of warnings.

The conversation covers the gap between theoretical multisig knowledge and actual adoption, the trade-offs between anonymity and regulated inheritance paths, why newer layers attract attacks first, and the need for human review of AI-generated code at Bitcoin firms.

Bansal argues that cryptographic hardware will become ordinary infrastructure for everyone in an AI-driven internet, not a niche Bitcoin tool, and that mature risk systems rely on fractal networks rather than centralized controls.

Lightning Labs built Wavelength to deliver self-custodial Lightning payments without forcing users to run nodes, manage channels, or handle liquidity.

Olaoluwa Osuntokun, CTO and co-founder of Lightning Labs, and Michael Levin, VP of Product, join me to detail the design choices behind their Ark implementation.

They explain why Ark was selected, how hop hints let every payment use ordinary Lightning invoices, and why the four-endpoint SDK targets AI agents and vibe coders. The conversation covers sub-dust vouchers, unilateral exits, offline payment delivery, and one-basis-point alpha pricing.

Wavelength shows that self-custodial Lightning can match the integration ease of custodial services while preserving Bitcoin sovereignty.

Old self-custody approaches collapse once Bitcoin reaches six figures, physical threats rise, and AI tools proliferate. Single hardware wallets and mattress myths no longer match the scale or risks that large holders now face.

Michael Tanguma, CEO and co-founder of Onramp, returns to examine how custody must adapt to family obligations, mortality, and market structure that turns concentrated holdings into targets.

The discussion covers why repeated exchange failures keep Bitcoin looking speculative to outsiders, how multi-institution setups reduce scam ROI, and the limits of adding more dice or vendors in an AI era. It also addresses custody pricing models and the practical question of whether any current setup survives a tenfold price increase.

Game theory now requires diversified institutional layers rather than pure self-reliance for serious stacks.
