When Robin Linus came out with BitVM, he believed he found the answer to this impossible problem, and has since poured his efforts into BitVM2 and BOB – a “hybrid L2” between Bitcoin and Ethereum.In this episode, we discussed:- Alexei’s long history researching Bitcoin bridges- The academic work on distributed systems- How BitVM changed t...2025-04-021h 18Bitcoin Rails | Isabel Foxen DukeDomo's Perspective & the History of BRC20 | With DomoA particularly special episode—@domodata sits down with me for his first video interview ever—to recount the unique history of the BRC20 protocol.The first Bitcoin-native token standard ever created, BRC20 came into existence almost overnight and quickly emerged as a multibillion dollar asset class in 2024.This episode covers the influences leading up to the birth of $ORDI, the roles of different players involved along the way, and how core maintainers are preparing for their next major update—affectionately dubbed “BRC 2.0” by Bitcoin educator @bobbodilyAdditionally, Domo shares his memory of key moments in BRC20 history—including:—the development of BRC20's can...2025-03-271h 14Bitcoin Rails | Isabel Foxen DukeAlkanes Are Fueling Programmable Bitcoin | With Oyl DynamicsEven after Ordinals, there’s a lot of infrastructure needed to make the Bitcoin economy work: wallets, indexers, interoperability, and programmable metaprotocols.

Despite unlocking Ordinals and BRC20, the real pathway to Bitcoin DeFi remains a mystery.
Chad Masterson – co-founder of OP_NET – believes an all-new Bitcoin L1 metaprotocol is needed for the job, which he says will “change Bitcoin without changing Bitcoin’s code.”
Today, we covered:
- Chad’s bitcoin price target this cycle
- Why Chad isn’t bullish on Bitcoin L2s yet
- How OP_NET improves on Ordinals as a metaprotocol

...2025-01-231h 08Bitcoin Rails | Isabel Foxen DukeThe Case For Lightning MaximalismAfter learning about all sorts of new Bitcoin L2s, Lisa Neigut (aka Nifty). my very first podcast guest, has returned in person to lecture me about why Lightning Network is still the best!
Lisa’s “lightning maximalism” is rooted in “payments maximalism.” If you purely intend to expand bitcoin’s utility as a payments tool, she argues that lighting – in conjunction with federated protocols and ecash mints like Fedi – can get the job done. Much to my surprise, those two worlds have been building roots together and creating synergies for some time, including through wallets like Aqua that make L...2025-01-201h 02Bitcoin Rails | Isabel Foxen DukeWe Don’t Even Need Bitcoin Bridges | With Arch’s Matt Mudano and Amine ElQaraoui (@ArchNtwrk)I spend a lot of time talking about “bridging” to L2s on my podcast, so I recently spoke to Amino and Matt from Arch to talk about why it still isn’t time to stop building for Bitcoin DeFi right on Layer 1.
Arch uses an entirely new VM inspired by Solana, but tailor-made to Bitcoin needs, including UTXOs and PSBTs. Arch can operate much like a traditional L2 that “bridges” funds for users, but can also allow programmable transactions to execute at the L1 level using Arch smart contracts, giving users a “choose your own adventure” secuirty exper...2025-01-1344 minBitcoin Rails | Isabel Foxen DukeHow Are Bitcoin Layer 2s Reviewed? | With Janus (@januszg_)As a full-time researcher of Bitcoin Season 2, Bitcoin Layers co-founder Yah-Noosh (Janus) is becoming cynical: “It’s all a massive shitcoin casino.”
Janus sat down with me for an hour in person to discuss how his research group compares and rates the swell of Bitcoin L2s now entering the fray, ranging from lightning, to rollups, to federated sidechains. As emerging BitVM and ZK-based layers fight to gain traction while remaining decentralized, he later argued why such projects will inevitably launch tokens as a reality of doing business.

David began by unpacking the history of zero-knowledge proofs, what Ethereum has already done with them, and the potential they create for allowing “rollups” on Bitcoin - a promising solution for bringing scalability, privacy, and programmability to the original chain. David and the Alpen team are currently building Strata, a “trust-minimized” ZK-based rollup on Bitcoin.
