Bitcoin Builds New Tools as AI Lowers Barriers

Sunday, March 15, 2026 · from 4 podcasts
Bitcoin OptechTFTC: A Bitcoin PodcastCitadel DispatchStacker News Live
  • AI has lowered the technical barrier to building Bitcoin apps, letting non-coders turn ideas into functional software just as the race for automated 'agentic payments' begins.
  • New Layer 2 protocols like ARK create novel 'half-key' sovereignty challenges, prompting independent verification tools to safeguard users in a rapidly innovating ecosystem.
  • Growth is tangible, with merchant adoption surging 74% in 2025, even as builders stress-test network security in exploit-focused hackathons.

The tools to build on Bitcoin are now in everyone's hands. According to Matt Corallo on TFTC: A Bitcoin Podcast, the last three months of AI advancement mean you no longer need to be a developer. Anyone with an idea can now use models like Claude 3.5 to construct real software, from mobile apps to payment rails.

This democratization arrives at a pivotal moment. A new frontier of commerce is opening with AI agents that will autonomously make purchases. Legacy payment networks like Visa are incompatible with this bot-driven future. Matt Corallo argues this levels the playing field. For the first time, Bitcoin isn't trying to displace a dominant incumbent. Everyone, from Google to Stripe, is starting from zero to build the standard for agentic payments.

The Bitcoin community's advantage is its density of early adopters eager to experiment. The race is on now, and the capability to build is no longer the limiting factor.

Parallel to this building boom, the protocol itself is evolving in complex ways. New Layer 2 solutions like ARK introduce sophisticated trade-offs. As explained on Bitcoin Optech, ARK creates a 'half-key problem' where a user needs both a private key and a specific map to their funds to exit unilaterally. This complexity demands new forms of verification.

Projects like VPAC are emerging as independent audit layers for different ARK implementations. They provide a neutral check on the complex transaction trees being built, ensuring users maintain sovereignty as the underlying code changes rapidly. This reflects a maturing ecosystem that is proactively addressing the security implications of its own innovation.

While builders work on the future, current adoption is accelerating in measurable terms. River Financial's annual report, discussed on Stacker News Live, showed global merchant adoption grew 74% in 2025, led by a 192% surge in North America. This economic growth happens alongside a relentless focus on security, evidenced by exploit-focused hackathons like Bitcoin++ that reward finding and fixing network vulnerabilities.

The narrative is converging. Lowered barriers are unleashing a wave of builders just as the protocol wars for the next generation of payments begin. The infrastructure is simultaneously hardening for security and simplifying for users, creating the foundation for the next phase of utility.

Matt Corallo, TFTC: A Bitcoin Podcast:

- For agentic payments everyone's starting from zero and so we have a shot to actually build something that people use.

- The race is starting now uh there's three or four or five different competing standards now being pushed by various payment companies ai labs whatever um and we need to be a part of that fight.

Bitcoin Optech: Newsletter #395 Recap • Mar 11

  • Bitcoin's ARK Layer 2 protocol creates a sovereignty gap where users cannot exit funds using only their private key.
  • John from VPAC describes the ARK exit challenge as a 'half-key problem', requiring both a private key and a specific map to locate a user's virtual unspent transaction output.
  • VPAC is a new verification standard designed to act as an independent audit layer for ARK implementations like Arcade and Bark.
  • VPAC verifies the existence of a user's exit path within the complex Taproot transaction tree of an ARK implementation.
  • John argues VPAC provides a crucial second set of eyes on rapidly evolving ARK code, ensuring no hidden backdoors exist in the tree structure.
  • VPAC aims to become a neutral standard across divergent ARK implementations, maintaining user sovereignty as Layer 2 innovations accelerate.
  • John applied for OpenSats funding to continue work on path exclusivity verification for VPAC.
  • Future VPAC development goals include hardware wallet integration and transaction broadcasting tools for worst-case scenario exits.
  • John notes that future Bitcoin covenants like TxHash or CSFS could simplify VPAC's verification job by reducing ambiguity about fund destinations.

CD194: SIDESWAP - LIQUID PREDICTION MARKETS • Mar 9

  • The Liquid sidechain is Bitcoin's underutilized layer for asset issuance and confidential transactions, struggling against custodial models and flashier smart contract alternatives.
  • Scott explains that Sideswap functions as a bulletin board and order book where dealers compete to set prices, aiming for better pricing and trustless settlement.
  • Scott says deeper infrastructure includes a peg service for bridging chains and open dealing software for market makers.
  • Scott attributes Liquid's slow growth to Bitcoin's single-asset nature and the initial allure of chains offering easier smart contracts, and notes major custodians like Fireblocks haven't integrated Liquid.
  • Scott says adoption is creeping forward organically, with Brazilian stablecoin Depix leading in transaction count on their platform, though Tether dominates total volume.

Also from this episode:

Custody (3)
  • Scott, cofounder of Sideswap, built a noncustodial wallet and swap market based on atomic swaps, allowing two parties to trade directly without an intermediary.
  • Odell notes that for average users, Sideswap simplifies moving between mainchain Bitcoin, Liquid Bitcoin, and Liquid Tether.
  • Scott notes Sideswap's cash-flow-positive, quiet build contrasts with the custodial, opaque swap services that dominate the space.
Privacy (1)
  • Scott believes Liquid's path forward relies on organic growth and products that leverage its privacy features, like wallets using it as a base layer for Lightning payments.

#723: The Battle for the Agentic Economy with Matt Corallo • Mar 8

  • Matt Corallo argues that recent AI models like Claude 3.5 have crossed a threshold in the last three months, enabling the creation of functional software, from front ends to mobile apps, without human coding.
  • According to Matt Corallo, this leap in AI model quality removes the technical skill barrier for the Bitcoin community, allowing anyone with an idea and the will to execute to build Bitcoin applications.
  • Matt Corallo says the emerging agentic economy presents a major opportunity for autonomous AI payments, where agents will handle routine purchases like reordering household supplies, representing a genuine slice of future consumer spend.
  • Matt Corallo states that legacy payment networks like Visa are useless for agentic commerce, as their systems are fundamentally anti-bot by design to prevent fraud.
  • Matt Corallo notes that stablecoins also fail to serve the agentic payment need due to a lack of merchant integration and usability for automated transactions.
  • Matt Corallo argues the race to build the default payment rail for AI agents is wide open, with entities like Google, Stripe, Visa, and crypto projects all pushing competing protocols from a starting point of zero.
  • According to Matt Corallo, this represents a unique shot for Bitcoin to achieve mainstream merchant adoption, as it is not trying to displace a 10x better incumbent but is competing in a newly forming market.
  • Matt Corallo concludes that winning the agentic payment protocol war requires the Bitcoin community to step up and build, using the newly available AI tools to turn weekend ideas into working products.
