Cracking The Bitcoin Bridging Problem | With Alexei...

Bitcoin Rails | Isabel Foxen Duke ·

2025/04/02

Build on Bitcoin (BOB) co-founder Alexei Zamayatin is older than he looks folks: he’s been researching how to build “trustless” Bitcoin bridge architecture since 2018, long before it felt anything close to a mainstream conversation. 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

Even after Ordinals, there’s a lot of infrastructure needed to make the Bitcoin economy work: wallets, indexers, interoperability, and programmable metaprotocols. Today's guests – Oyl Dynamics co-founders Alec Taggart and Ray Pulver – are building one software suite to tackle all of these problems, including the tools for anyone to spin up their own metaprotocol!In today’s episode, we discussed:The advantages of building on Bitcoin vs EthereumThe need for interoperability between Bitcoiin

2025/03/12

There’s a few different softfork proposals floating around to build “covenants” on Bitcoin - but which one is the best? I had Janus (that’s “Yah-NOOSH”) back on the pod at ETH Denver – this time with his partner Red from Bitcoin Layers – for a technical talk on the differences between them, and the consequences of changing or NOT changing Bitcoin. In today’s episode, we discussed:- The difference between CTV, TXHash, and OP_CAT- The limited time we have to change Bitcoin- Advantages of Bitcoin

The Future Of Bitcoin DeFi | With Dan Held And FarmerJoe

Bitcoin Rails | Isabel Foxen Duke ·

2025/03/06

Bitcoin culture wasn’t always about eating red meat. The desire for L2s, DeFi, and experimentation are part of Bitcoin’s earliest roots, and those are the areas that the Asymmetric Bitcoin DeFi Venture Fund is investing in. In our chat at ETH Denver, creators Dan Held and FarmerJoe took me through the history. In this conversation, we discuss:Being early to Bitcoin DeFiWhy Dan and FJ ONLY buy into projects with tokensWhy money isn’t Bitcoin’s only use caseOld vs new Bitcoin maximalismWhether Bitcoin

CoreDao contributor Rich Rines says that Core Network provides a way for HODLers to do that – without needing to trust any bridge or custodian!In this conversation, we discussHow Core Network combines both Proof of Stake and Proof of WorkWhether CoreDao is a Bitcoin “L1” or “L2”Why Core has proven so successful with a “fair launch” tokenWhether utility tokens can make a comeback under the new

In this extra-rich TWO HOUR episode of Bitcoin Rails, Ordinal Show host and $DOG token co-founder @LeonidasNFT told me about his journey between Bitcoin and Ethereum maximalism, and what led him to launch the most successful Rune on Bitcoin. Unlike Beezy, Leo believes $DOG is a shining example of how Runes can make it, and says we ought to collectively migrate from BRC-20.We discussed:- Leo’s evolution between Bitcoin and Ethereum maximalism- His history as an NFT “archaeologist”- Leo’s distaste for

2025/02/13

With all the pain and cope in the Ordinals ecosystem lately, I needed *immediate* answers. That’s why I called up Beezy – former Galaxy researcher and walking Ordinals encyclopedia – to tell me why Ordinals needs a defibrillator to “kind of bring it back to life.”In this episode, we chat about:Why Runes are on life supportHow Runes were never optimized to be usefulWhy we should ditch Runes and return to OrdinalsWhat made Ordinals special, and what to refocus onThe role of KOLs in the Ordinals

2025/01/23

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 - Deploying smart contracts into Bitcoin L1 transactions - Why devs are

The Case For Lightning Maximalism

2025/01/20

After 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

2025/01/13

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

2025/01/09

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

2025/01/07

I just had a mind-bending discussion with David Seroy - ecosystem lead at Alpen Labs (and fellow Bitcoin Season 2 podcast host) - about the genesis of zero-knowledge cryptography on Bitcoin. 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

2024/12/16

It’s now been two years since Bitcoin’s first inscription, so I caught up with Trevor Owens – Host of The Ordinal Show – to update me on what’s going on in the world of Bitcoin NFTs. While discussing his recent Pizza Pets Ordinals airdrop, Trevor recapped how Ordinals have evolved over the past two years into an NFT market that can rival Ethereum’s. In Trevor’s view, the Bitcoin bull market hasn’t even started yet. When it does, there will be an “exponential jump” of investors' interest ...

Lisa Neigut is the founder of Bitcoin++, co-founder of Base58, and a former Lightning Network engineer at Blockstream. In this inaugural episode of Bitcoin Rails, Lisa and I chat about the explosion of so-called "Bitcoin Layer 2s" spawning across the industry, including what defines an “L2”, and what makes some L2s better than others. We talked about some of the different types of L2s including E-Cash mints and ZK layers, and how their trust assumptions compare to existing layered solutions
