Release Date: 12/10/2024
ATL BitLab Podcast
Broadcasting live from ATL BitLab on Friday, March 13th, 2026, Stephen DeLorme and Alex Lewin cover Matt Corallo's 24-bit nonce space BIP moving to draft PR (fast-tracking good ideas), Dahlia's cross-input signature aggregation accepted at Eurocrypt (holy grail cryptography), and BDK 3.0 release candidate after years of development (SQLite migration unlocking new features). Protocol developments include Rusty Russell requesting BIP numbers for Great Script Restoration proposals (reactivating opcodes with var ops budget for safe execution), Cold Card's proof of reserves feature via BIP 322...

Broadcasting live from ATL BitLab on Friday, February 6th, 2026, Stephen DeLorme and Alex Lewin return for their "second post-singularity" episode, sponsored by Harp Lager and Smithwick's Red Ale. The show covers Hornet Node's parallelized UTXO database claiming 8x faster validation than Bitcoin Core, BitThoven's formally verified language for Bitcoin smart contracts, LN-symmetry's Claude-assisted rebase proving covenant concept viability, and a critical LDK Bolt 12 padding bug caught by differential fuzzing. Then the episode shifts tone dramatically: Gloria Zhao steps down as Bitcoin Core...

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...

Broadcasting live from ATL BitLab on Thursday, January 15th, 2026, Stephen DeLorme and Alex Lewin return from holiday break to cover Bitcoin technical developments. The episode opens with BIP-3's deployment—a major overhaul to the Bitcoin Improvement Proposal editorial process after two years of debate. The hosts then dive deep into René Pickhardt's new mathematical theory of payment channels, exploring how geometric modeling reveals fundamental limits on Lightning Network feasibility and why channel factories become necessary for scaling. The conversation shifts to speculative financial...

Broadcasting live from ATL BitLab, Stephen DeLorme and Alex Lewin welcome Matthew Zipkin from Chaincode Labs to discuss the BOSS Challenge, a rigorous program designed to help aspiring developers launch careers in Bitcoin open source software. The conversation explores what it takes to become a Bitcoin protocol developer, the appropriate use of AI in learning and development, and how the program identifies serious contributors through a three-month gauntlet. The episode then shifts to technical updates: the proliferation of "ARK" naming conflicts across Bitcoin projects, Stratum V2's progress...
