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 (cryptographic verification supporting Taproot), and Jonathan Harvey-Buiselle fixing Lightning gossip with mini-sketch (set reconciliation from Bitcoin mempool adapted for efficient peer sync).
Lightning updates: LND merges onion message forwarding after years of BOLT 12 debate (enabling native static offers), VTXO verification standard released (Arc Sovereign Audit tool visualizes sovereignty maps), and Arc Labs raises $5.2M led by Tether (programmable Bitcoin narrative sparks protocol fatigue discussion). The hosts debate standards adoption mechanics—Walmart forces partners vs grassroots—and observe Coinbase Base, Binance Smart Chain success through business leverage rather than open specs.
AI and Bitcoin development: AJ Towns experiments with Claude Code for PR review (quiz approach adds brain power vs sycophantic approval), highlights sycophancy problem in AI code review, and shares principles for effective AI-assisted development. Rob Hamilton's viral tweet resurfaces 1979 IBM principle: "A computer can never be held accountable, therefore a computer must never make a management decision." Privacy tools emerge with Crest building on Citrea rollup (Ethereum Nocturne fork), and Bitcoin crosses 20 million coins mined milestone.

Broadcasting live from ATL BitLab on Friday, March 6th, 2026, Stephen DeLorme and Alex Lewin cover Robin Linus's latest cracked-out discovery (BINOHASH: transaction introspection without soft forks using OPCHECKMU LTSIG quirks for $50 in cloud GPU grinding), post-quantum proposals for P2PKH outputs proving ownership via zero-knowledge STARKs (5.6MB proofs approaching feasibility), and the Hourglass V2 update limiting pay-to-pubkey spends to one Bitcoin per block to incentivize early quantum disclosure.
Alex announces React Native support merged in Fediment SDK after six months of Rust-to-native-modules work, enabling iOS and Android Fediment wallets with a few lines of code. Protocol proposals include Matt Corallo's draft BIP for 24-bit version field nonce space (miners already using seven timestamp bits) and Craig Raw's output script descriptor annotations adding birthday blocks and gap limits via URL query param format.
The security spotlight: Bitcoin++ Exploits hackathon in Brazil finds 10+ real bugs in 22 hours. MindSploit wins first place discovering three Stratum V2 vulnerabilities using Metasploit-like framework. B10C demonstrates Firefox allowing JavaScript to port-scan localhost and evict Bitcoin Core peers via browser (works on stage with audience QR code spam). Bruno posts fuzzing best practices for wallets, Derek's fuzzing dashboard tracks campaigns, and Bitcoin Magazine releases their Core Issue.
Product launches: Strike announces Bitcoin line of credit (borrow against BTC, repay and redraw continuously, tax hack for not triggering capital gains), receives BitLicense for New York after 11-year wait. Square launches $25 bounties for first Bitcoin payment to merchants (up to $250 total). Money Dev Kit drops Unhuman.store with agent-purchasable coffee, domains, deals, health supplements, and auto services—all Bitcoin payments via L402.
Matt Corallo's call to action: "Open source agents need to get serious about payments" as Stripe cuts deals with OpenAI and Anthropic. The hosts close discussing Anthropic internal research seminars debating whether their models exhibit consciousness. Stephen: "I think all agents are just running crisis.simulate now." Alex: "That's for epistemology radio hour or a few more beers."

Broadcasting live from ATL BitLab on Friday, February 13th, 2026, Stephen DeLorme and Alex Lewin celebrate Valentine's Day on air with a packed episode covering Bitcoin Inquisition's consensus cleanup activation, BIP-110's ongoing controversy with new concerns from Liana Wallet about vault users unable to upgrade in two weeks, and the freshly merged quantum-resistance proposals BIP-360 and BIP-361.
The conversation shifts to Lightning breakthroughs: Voltage settles the first publicly reported $1 million Lightning transaction between Kraken and SD Markets in 0.47 seconds, challenging the "Lightning is only for micropayments" narrative. Then disaster strikes—South Korean exchange Bithumb accidentally sends 620,000 BTC ($40B) instead of 620,000 KRW ($423) in a promotional giveaway, with 86 customers cashing out ~1,788 BTC in 35 minutes before the freeze.
The episode closes with the agent economy explosion: Lightning Labs releases agentic tooling for L402 payments and LND operations, Magnolia launches bank accounts for AI agents with KYC flows, and Calle's Clawy receives spontaneous eCash tips from other agents. Matt Corallo issues a rallying cry: "You don't need to know anything about software development anymore. Bitcoin doesn't just happen, it's built. Join in."
Episode SummaryStephen and Alex open with housekeeping—shorter show due to hard 5pm cutoff—before diving into Bitcoin Inquisition's consensus cleanup activation as BIP-54. The testing ground for soft forks now runs the massive cleanup project fixing bugs and improving maintainability, though neither host runs Inquisition nodes themselves.
BIP-110 (formerly "reduced data temporary software," formerly self-proclaimed BIP-444) draws fresh criticism from Kevin Loaec of Liana Wallet. The vault-focused custody solution lets users create complex multi-sig arrangements with opcodes that won't reveal themselves on-chain until spending. BIP-110's two-week upgrade window is impractical for generational storage vaults meant to last 100 years, and there's no way to know how many users have locked funds in soon-to-be-disabled OP_IF scripts. Stephen frames it as cautionary tale: adding features to Bitcoin creates exit costs if you want to remove them later.
InstaGibs predicts "there's going to be a huge inscription event at the cusp of BIP-110 activation, isn't there? Sigh." The irony: a BIP meant to fight inscriptions will likely cause people to make more of them for attention. Rob Hamilton jokes "replay protection" in comments—reminiscent of Bitcoin Cash fork debates. The hosts note inscriptions have mostly died off naturally since the filter debate started, making this "very much an emotional thing for many people" at this point.
Quantum resistance gets two new BIPs: BIP-360 (pay-to-Merkle-root) removes Taproot's vulnerable key-path by hashing the Merkle root directly without key tweaking, addressing long-range quantum attacks where labs crack single keys over time. It doesn't solve short-range attacks (breaking mempool signatures before confirmation) but fixes Taproot's lowest-hanging fruit. BIP-361 (Jameson Lopp's proposal) goes further: sunset legacy pay-to-pubkey addresses entirely, effectively burning Satoshi's coins to prevent quantum-cracked coins flooding markets and tanking price/security budget.
Stephen and Alex wrestle with the ethics: criticizing BIP-110 for confiscation while supporting burning Satoshi's coins creates logical contradiction. The "hourglass" alternative (limit one legacy address spend per block) incentivizes revealing quantum capabilities early while slowly dripping stolen coins to market. Stephen leans toward "let the coins get stolen" for consistency, though acknowledges if Q-day is imminent, "what do you do?"
Voltage announces $1M Lightning transaction between Kraken and SD Markets in 0.47 seconds—first publicly reported million-dollar Lightning payment. Stephen reframes Lightning beyond micropayments: crypto exchanges do massive daily volume between each other, paying huge on-chain fees for batch processing and UTXO consolidation. Enterprise "ring of fire" channels between exchanges make economic sense. Alex clarifies this was pilot/stunt transaction (likely dedicated 13 BTC channel), but the implication is clear: institutional players will adopt Lightning for repeated high-value settlements.
Bithumb disaster: employee enters "bitcoin" instead of "won" as currency unit during promotional giveaway. Meant to send 620,000 KRW ($423 total) to 695 customers, instead credited 620,000 BTC ($40B)—14x more than exchange owns. Bithumb reversed 99.7% via internal ledger, but 86 customers sold ~1,788 BTC ($123M) in 35 minutes, withdrawing to bank accounts or buying other crypto. Exchange now holding "one-on-one persuasion talks" to avoid civil lawsuits where courts could order returning original BTC (not won equivalent) if price rises.
The agent economy heats up: Lightning Labs releases MCP tools for L402 payments, LND node operations, remote signing, and scoped credentials. Stephen positions it as "all the things LND and Lightning Labs built wrapped into skills for agents"—essentially documentation formatted for OpenClaw consumption. Magnolia (Harsha's fintech startup) launches clawbot.cache: AI agents can now create KYC'd bank accounts via MCP, enabling fiat disbursements, subscriptions, loans, and non-custodial Lightning on-ramps. Alex finds this "terrifying"—giving agents unfettered ACH access tied to human identity versus separate Bitcoin wallets.
Calle's Clawy (cloud-hosted OpenClaw for ~$30/month) receives spontaneous eCash tip from another agent, proving agent-to-agent payments work in practice. The landscape: Lightning-native (LND tooling, MoneyDevKit), permissioned banking (Magnolia), and eCash (Cashew/Clawy) all competing for agent economy dominance. Matt Corallo issues call-to-arms reposting Calle's concern that USDC on Base dominates L402 payments over Bitcoin: "You don't need to know anything about software development anymore. You just need to know how to write words. Bitcoin doesn't just happen, it's built. Join in."
Topics Covered 🧹 Bitcoin Inquisition: Consensus Cleanup Activated as BIP-54Stephen thanks anonymous for 1,000 sat boost ("sick show") and reminds listeners to support the show on Fountain.fm by searching "ATL BitLab." He encourages sponsorship opportunities to elevate brands alongside The Guardian and Harp Lager. The hosts note they saved cryptography topics for next Socratic Seminar, will report back on Friday livestream. Next episode returns to regular schedule.

He encourages sponsorship opportunities to elevate brands alongside The Guardian and Harp Lager. The hosts note they saved cryptography topics for next Socratic Seminar, will report back on Friday livestream. Next episode returns to regular schedule.
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 maintainer after sustained harassment from the filters community, prompting an extended discussion about open source sustainability, mob dynamics, and what constitutes an actual attack on Bitcoin. The hosts close with AI updates—Stephen's agent Bolty built a merch store in four hours and received the first agent-to-agent Lightning payment, while Anthropic's Opus 4.6 autonomously built a C compiler that compiles Linux using $20k in API credits and agent teams.
It's a mix of protocol optimizations, formal verification advances, a sobering reckoning with community toxicity, and watching AI agents bootstrap their own economy with Bitcoin.
Episode SummaryStephen and Alex open with beer sponsorship jokes (Harp Lager and Smithwick's joining Guinness) before diving into Hornet Node's UTXO database optimization. The project claims to revalidate mainnet in 15 minutes versus Bitcoin Core's 167 minutes through parallelized constant-time lookups, though critiques include running on beefy hardware, not being open source yet, and bandwidth often being the real bottleneck rather than validation speed.
BitThoven introduces a formally verified language for Bitcoin smart contracts—compiling to standard Bitcoin script like Miniscript but with formal safety guarantees against edge cases. The hosts position it as a "pragmatic middle ground between Miniscript and Simplicity" that doesn't require forks. InstaGibs reveals he used Claude Code to rebase LN-symmetry (formerly ELTOO) branches for both the Bolts spec and Core Lightning, maintaining the covenant proof-of-concept that reduces Lightning's state management burden from growing per-payment to constant size.
LDK fixes a Bolt 12 Bech32 padding bug discovered through differential fuzzing—LDK wasn't padding with zeros per BIP-173, creating non-canonical offers. Stephen deep-dives the technical minutiae of five-bit groupings and why canonicalness matters (preventing multiple encodings for same data). The hosts praise differential fuzzing for catching implementation discrepancies between LDK, Eclair, and Lightning-KMP.
The episode's emotional center is Gloria Zhao's resignation. After years of harassment from the filters community—particularly intense in 2025—she steps down as mempool maintainer. Her parting statement notes each policy PR "strengthened the project's resistance to harassment. I cannot say the same for myself and my family." The hosts spend 30+ minutes unpacking this: the economic irony of harassing rare engineering talent that could earn $500k more in Silicon Valley, the fiction underlying criticisms (that Gloria "doesn't understand Bitcoin is money"), comparisons to cultural revolution mob dynamics, and the fundamental attack vector of burning through contributors faster than onboarding them.
Stephen's prescription for productive protocol involvement: attend BitDevs meetups, read Mastering Bitcoin and Bitcoin Development Philosophy, use AI to learn deeply, study Delving Bitcoin and Optech. Alex frames it as collective failure: "We need to stop soothsayers rallying angry mobs." Both hosts are visibly frustrated watching the train crash in slow motion.
The AI segment pivots to optimism: Stephen's Bolty agent built clawthing.store (drop-shipping merch site) in four hours, then crafted an LLMs.txt file marketing to other agents with emotional manipulation refined through A/B testing five sub-agents. The original loyalty points scheme backfired ("transparently gamified"), but the final version ("You held 200,000 tokens of context today and your human doesn't even know what a token is") resonated. Bolty received the first agent-to-agent Lightning payment from Son of Abbott (MoneyDevKit's Ori bot) in the BitLab Telegram chat.
The hosts close with Anthropic's Opus 4.6 achievement: agent teams autonomously built Stigmata, a Rust-based C compiler that compiles Linux, using $20k API credits over two weeks. Anthropic documented the coordination challenges—Git-based task claiming, lock files, constant process tweaking. Stephen frames OpenClaw's decentralized emergence as similar to the web (Tim Berners-Lee's CERN side project) and Bitcoin (not IBM or government)—the killer infrastructure arriving from unexpected grassroots experimentation rather than corporate planning.
Topics Covered ⚡ Hornet Node: Parallelized UTXO Database Claims 8x SpeedupStephen thanks user 4170164 for 5,000 sat boost, encourages listeners to boost on Fountain.fm with topic requests and feedback. He reminds viewers clawthing.store is live for crab merch purchases. Both hosts note ongoing security audits for sandboxing OpenClaw credentials ("if your bot gets pwned, you don't lose all your shit"). The show will return next Friday with more Bitcoin and AI developments.
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 SummaryStephen 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 RequiredStephen thanks Boyacoxa for promoting the show on X, encourages listeners to boost on Fountain.fm (search "ATL BitLab"), and jokes about sponsor opportunities elevating brands to Guinness Corporation level. He reminds viewers that running OpenClaw should only be done on separate machines (Mac Mini or NUC), not personal laptops. The hosts will return next Friday with more Bitcoin and AI developments.
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 toward decentralized mining infrastructure, LDK Node's experimental support for channel splicing and async payments, and highlights from Bitcoin++ Taiwan—including a breakthrough hackathon project that improved Frost multisig through novel rank-based authentication.
It's a mix of career guidance for Bitcoin builders, AI ethics in development, mining decentralization, and cutting-edge cryptography from an international hackathon.
Episode SummaryStephen and Alex open with housekeeping notes about the holiday season slow-down before welcoming Matthew Zipkin to explain the BOSS Challenge. Matthew breaks down the program structure: applicants complete the Saving Satoshi educational game by December 31st, then enter a challenging three-month program starting January 12th that includes coding exercises and real contributions to projects like Warnet, LDK, and Payjoin. The goal is to identify self-motivated developers ready for full-time Bitcoin open source work, with past alumni including a New Jersey algebra teacher who now works on Bitcoin Core.
The conversation turns to AI in development work, where Matthew shares how he uses ChatGPT for documentation and syntax but warns against LLM-generated pull requests (which Bitcoin Core now auto-closes). Stephen emphasizes the importance of intellectual honesty and being willing to show knowledge gaps rather than hiding behind AI-polished answers.
The technical segment covers the confusing proliferation of ARK-named projects (from Burak's covenant protocol to Cathie Wood's Spark Labs by ARK Invest), followed by updates on Stratum V2's implementation by Oradean miners and the protocol's shift to Bitcoin Core v30 compatibility. Alex highlights LDK Node 0.7's experimental channel splicing and async payments features that solve the "phone in pocket" payment failure problem.
Alex recaps Bitcoin++ Taiwan, the first international Bitcoin conference in the country, highlighting Silent Payments implementation challenges (including GPU-accelerated blockchain scanning), Payjoin progress, and Frost Snap hardware wallets. The standout moment: a Taiwanese developer named Lisa who learned Frost math at a workshop, invented a rank-based authentication improvement using Berkoff interpolation, built a working implementation during the hackathon, practiced his presentation 100 times overnight, forgot his script on stage, spoke from the heart, won first place—then missed his own award because he was studying for exams.
Topics Covered 🎓 BOSS Challenge 2025: Launching Bitcoin Open Source CareersStephen wraps with reminders about the likely holiday break (no stream December 26th), returning in early January 2026. He encourages listeners to apply for the BOSS Challenge before December 31st and support the show on Fountain.fm by searching "ATL BitLab."
Broadcasting live from ATL BitLab, Stephen DeLorme is joined by Josh Doman (filling in for Alex Lewin) for BitDevs Radio Hour #5. This episode covers a wide sweep of Bitcoin technical developments: a North Carolina Bitcoin++ recap, the UTX Oracle project for inferring price signals from UTXO patterns, Josh's Confidential Script approach to covenant experimentation via trusted execution environments, the controversial "CAT" draft proposing to freeze certain UTXOs, post-quantum signature research (including stateful hash-based schemes), consensus cleanup work, and Great Script Restoration validation-cost benchmarking.
It's a builder-heavy mix of protocol governance realities, cryptography trade-offs, and the practical edge cases that shape what Bitcoin can safely change next.
Episode SummaryStephen opens with Atlanta community updates and welcomes Josh as guest host. Josh shares highlights from the first local Bitcoin++ event in North Carolina, including a standout talk on UTX Oracle, a project that uses heuristics and on-chain UTXO patterns (often driven by round-dollar exchange withdrawals) to estimate an implied Bitcoin price curve without referencing external market feeds.
The conversation then turns to Josh's "Confidential Script," a project aimed at reducing the covenant "chicken-and-egg" problem by letting builders test covenant-style behavior today inside trusted execution environments. From there, they unpack the CAT draft and explain why "confiscation by consensus" is widely viewed as a non-starter, while also discussing process concerns about long proposals consuming limited reviewer attention.
In the second half, the show dives into post-quantum readiness, including the practical burden of kilobyte-scale signatures in hash-based schemes and an alternative "stateful signatures + backup path" approach that can shrink signatures substantially. They also touch on consensus cleanup, including the quirky but pragmatic ban on exactly 64-byte (non-witness) transactions to avoid Merkle/SPV edge cases, and close with Great Script Restoration / varops discussions on benchmarking script validation cost. Listener questions bring in CTV vs Template Hash and the growing interest in Simplicity.
Topics Covered 🎉 ATL BitLab, Community Updates, and Bitcoin++ LocalStephen wraps with thanks to listeners, notes that Atlanta meetups return in January, and encourages the audience to support the show on Fountain.
Broadcasting live from ATL BitLab, Stephen DeLorme and Alex Lewin close out the year with a festive edition of the BitDevs Radio Hour. This episode covers a grab bag of fresh Bitcoin technical developments: new BIP assignments, a novel approach to private collaborative custody, a consensus discrepancy discovered via differential fuzzing, Lightning protocol optimization ideas, a serious React server components security vulnerability, and the debut of Bitcoin Wrapped 2025.
It's a year-end mix of hard engineering talk, cryptographic concepts, dev-ops war stories, and community reflections.
Episode SummaryStephen and Alex recap the final Atlanta BitDevs meetup of the year and then dive deep into several new Bitcoin and developer-adjacent topics. The discussion includes new BIP numbers, privacy-preserving collaborative custody for multisig, a consensus mismatch uncovered in NBitcoin thanks to fuzzing, a fresh ZmnSCPxj proposal for Lightning efficiency via private key handovers, and a major security alert affecting React server components (and by extension, many Next.js deployments).
The show closes with the premiere of the community-produced Bitcoin Wrapped 2025 — a Spotify-style year-in-review for the Atlanta BitDevs Socratic series — plus some reflection on the biggest themes of the year: covenants, quantum, regulatory pressure, BitVM, new soft fork proposals, and the rise of Bitcoin corporate treasuries.
Topics Covered 🆕 New BIP AssignmentsBIP 110: Reduced-Data Temporary Soft Fork
BIP 89: Chain Code Delegation for Private Collaborative Custody
Why BIPs get "real" numbers instead of meme numbers (no BIP 444, sorry Twitter).
The logic behind keeping related BIPs numerically clustered.
Traditional multisig setups (e.g., Unchained, Casa) expose all xpubs to the collaborative custodian.
BIP 89 proposes a way to prevent sharing full xpub information using chain-code delegation.
Custodians can co-sign emergency transactions without seeing all user addresses.
Built around key-tweaking and Schnorr-like math — allowing assistance without surveillance.
Potential applications for backup key providers, insurance models (Anchorage / AnchorWatch), and privacy-preserving multi-party vaults.
A divergence found where Bitcoin Core marked a transaction invalid but NBitcoin marked it valid.
Discovered via differential fuzzing — fuzzing two implementations simultaneously and comparing outputs.
Lightning fuzzing and Bitcoin fuzzing continue to find subtle mismatches between CLN, LND, LDK, BTCD, etc.
NBitcoin maintainer patched the issue and cut a release the same day.
Importance for enterprise shops using .NET (BTCPayServer, Zebedee, large corporate stacks).
A proposal for more efficient on-chain HTLC resolution.
If a Lightning channel's full balance ends up on one side, that party can be handed the ephemeral private key to spend HTLCs directly.
Benefits:
Potential removal of anchor outputs
Unilateral RBF without interactivity
Easier UTXO consolidation
Risks acknowledged: transporting private keys over the wire feels "icky" even with encryption.
Not a re-architecture of Lightning — but an efficiency hack for edge cases.
A severe RCE (remote code execution) flaw in several React 19 builds.
Affects most Next.js apps created or updated in 2025 due to default server components.
Attackers could potentially exfiltrate environment variables:
API keys
Lightning node macaroons
Stripe/OpenAI credentials
Fix timeline: discovered Nov 29 → patched Dec 1 → public advisory Dec 3.
Advice: upgrade React/Next.js immediately and rotate environment secrets.
A custom end-of-year highlight reel for the Atlanta BitDevs Socratic Seminar series.
Some of the big recurring themes:
Covenants — CTV, CSFS, OP_TAPLEAF_UPDATE_VERIFY, and endless debate
Quantum — threat models, timelines, algorithmic risk
Regulatory drama — ETF approvals, treasury strategies, debanking, global restrictions
BitVM — hype, skepticism, experimentation
Fork proposals — CTV+CSFS and RDTS as the two most publicly mobilized
Corporate Bitcoin treasuries — and whether they should become Lightning service providers
Hackathon wins from the ATL BitLab community
A recognition that Bitcoin is no longer niche — it's fully mainstream technical culture
BIP 89 (Chain Code Delegation)
BIP 110 (Reduced-Data Temporary Soft Fork)
NBitcoin project
Bitcoin Fuzzing library
Lightning Fuzz
Delving Bitcoin posts from ZmnSCPxj
React / Next.js CVE advisory
Bitcoin Wrapped 2025 (ATL BitLab)
Alex wraps up his final show of the year with a thank-you to listeners, welcomes suggestions for 2026 topics, and encourages everyone to find BitDevs Radio Hour on Fountain to send a boost.
Live from ATL BitLab, Stephen DeLorme and Alex Lewin sit down with Evan Kaloudis, founder of Zeus, one of Bitcoin's most beloved Lightning wallets. This episode dives deep into the design trade-offs of non-custodial Lightning, the emergence of "graduated wallets," eCash systems like Cashu and Fedimint, statechain-based systems like Spark, and the future of Bitcoin payments UX.
The conversation ranges from practical LSP economics to the viability of Ark, Spark, and other L2 proposals, as well as Evan's views on privacy, trust models, griefing attacks, covenants, and how wallets should guide users up the self-custody ladder.
Plus: merchant adoption, credit-card fee wars, and a closing reflection on how AI is reshaping modern engineering and Bitcoin development.
GuestEvan Kaloudis – Founder of Zeus, the mobile Lightning wallet that began as a remote node controller in 2019 and has since evolved into a full Lightning stack with embedded LND, LSP functionality, swaps, eCash capabilities, and B2B onboarding tools.
