Abstract

GOAT Network has launched the GOAT BitVM2 Testnet V3, a Bitcoin-native zkRollup solution designed to enable BTC participation in financial activities without relying on custodians, committees, or multi-signature trust assumptions. This testnet addresses the core challenge of whether Bitcoin can act as the ultimate arbiter for off-chain computations, ensuring security and trust in extreme scenarios like attacks or system failures. Unlike existing Bitcoin L2 solutions that depend on trusted bridges, honest majority assumptions, or external chain settlements, GOAT’s approach leverages BitVM2 technology. BitVM2 uses Bitcoin’s existing primitives—pre-signed transactions, one-time signatures, and Taproot—to create a challenge-based execution mechanism. This allows Bitcoin to enforce correctness and resolve disputes without requiring protocol upgrades. Key features of the testnet include: - Off-chain execution with zkVM-based validity proofs. - Transaction ordering anchored to Bitcoin. - Withdrawals and disputes ultimately settled by Bitcoin’s consensus rules. - Permissionless participation for challengers and verifiers. GOAT has enhanced BitVM2 for practical deployment by improving Bitcoin-anchored sequencing, enabling efficient withdrawals, reducing fraud-proof data volume by ~1000x via Garbled Circuits and DV-SNARKs, and implementing a 1-of-n honest security model. The system also includes a Type-1 zkEVM, decentralized sequencer architecture, and an audited zkVM (Zir...

Bitcoin-native zkRollup project GOAT Network today announced the official launch of the GOAT BitVM2 Testnet V3, a test network with Bitcoin as the final arbitration layer, designed to enable BTC to participate in real financial activities without relying on custodians, committees, or multi-signature trust assumptions.

For a long time, Bitcoin has been viewed as a "store of value" rather than a widely usable financial asset. Despite having a holder base worth trillions of dollars, once it involves cross-chain activities, yield generation, trading, or other financial behaviors, users often need to hand over control to third-party institutions or rely on implicit assumptions like majority honesty.

GOAT Network aims to solve this core contradiction:
When the system encounters problems, does Bitcoin itself have the ability to verify complex off-chain computations?

The Key Challenge of BTCFi: Can Bitcoin Be the Final Arbitrator?

Most current "Bitcoin L2" or BTCFi solutions still rely on one of the following structures:

Custodial or multi-signature bridges: Asset control is concentrated in the hands of a group of signers
<极p dir="ltr" role="presentation">Committee or majority honesty assumption: System security relies on participants staying online and remaining honest
Off-chain settlement: Final disputes are resolved on blockchains other than Bitcoin

These solutions work when the system operates normally, but in extreme situations such as attacks, downtime, or governance conflicts, Bitcoin itself cannot unilaterally enforce exits or arbitrate.

"The Bitcoin Layer 2 market hasn't truly begun yet. So far, so-called 'Bitcoin L2s' are essentially sidechains or custodial bridges. They lack permissionless exit mechanisms and the ability for dispute resolution enforced by the Bitcoin mainnet, which is the prerequisite for BTCFi to gain long-term trust."

Kevin Liu, Core Contributor to GOAT Network

BitVM2: Enabling Bitcoin to Participate in Arbitration Without a Protocol Upgrade

Due to Bitcoin's minimalist underlying design and lack of a general smart contract execution environment, "native Bitcoin Rollup" has long been considered difficult to achieve.

The breakthrough of BitVM2 lies in providing Bitcoin with a path to enforce correctness. It utilizes only Bitcoin's existing basic primitives, including pre-signed transactions, one-time signatures, and Taproot, to construct a challengeable execution mechanism, enabling malicious or forged proofs to be challenged and ultimately forced to a result executed by Bitcoin's consensus rules

On this basis, GOAT Network has advanced BitVM2 from theory to system-level implementation, expanding it into a complete, verifiable native Bitcoin zkRollup architecture.

Testnet V3 is the public testing environment for GOAT Network's native Bitcoin zkRollup technology stack, featuring the following core characteristics:

Layer 2 execution is completed off-chain, with its execution correctness guaranteed by zkVM-based zero-knowledge validity proofs
Layer 2 sequencing results are anchored on Bitcoin
Withdrawals and disputes are ultimately arbitrated by Bitcoin mainnet rules
Anyone can participate in challenging or verifying, rather than relying on a single operator

This means:
When the system runs smoothly, the user experience is similar to a high-performance L2; when problems occur, Bitcoin still has the final say.

What Has GOAT Done to Make BitVM2 Truly "Runnable"?

Building upon the theoretical design of BitVM2, GOAT Network has补充了 several key capabilities for real-world deployment scenarios:

1. Bitcoin-Anchored Sequencing and Historical Consistency

Proving "a state is valid" is not enough. GOAT anchors sequencing results on Bitcoin and binds withdrawals to that history, preventing operators from submitting alternative forks at the exit boundary.

2. Withdrawal Mechanism That Functions Like Real Currency

The system supports withdrawals of any amount, completed through atomic paths and block header chain verification, without relying on complex user-side操作流程.

3. Economically Executable Dispute Path (BitVM2-GC)

If the challenge mechanism is too costly, it will fail in reality. GOAT introduces a scheme based on Garbled Circuit (GC) and Designated-Verifier SNARK (DV-SNARK), reducing the amount of fraud-proof data that needs to be on-chain in the worst case by approximately 1000 times, making challenges executable within realistic cost ranges.

4. Security Model Based on 1-of-n Honesty Assumption

Through role rotation and on-chain collateral management, the system avoids degenerating into implicit trust in a few online participants during long-term operation.

In addition to the core BitVM2 mechanism, GOAT Network has also built complete system-level capabilities, forming a complete native Bitcoin zkRollup technical solution, including:

Type-1 zkEVM execution environment: Fully equivalent to Ethereum, reducing development and migration costs
Decentralized Sequencer architecture: Reduces single points of trust and censorship risk from the architectural level
Self-developed zkVM (Ziren) proof engine: Audit completed, used to generate execution validity proofs

Why is This Testnet Significant?

The GOAT BitVM2 Testnet is not an ordinary product release, but rather a public verification phase for system-level security assumptions:

For users: First-time experience of BTC usage and exit paths guaranteed by Bitcoin rules
For developers: Deploy full EVM applications on the native Bitcoin zkRollup, run Operator or Challenger nodes, participate in BitVM's optimistic challenge process
For the industry: Publicly answers the core question "Can Bitcoin truly bear a trusted financial system?"

The GOAT BitVM2 Testnet is now live and open to the public for testing. This is also the final phase before the GOAT Network mainnet launch, where all key assumptions undergo real-world testing.

It Took Me a Year to See the Bitter Truth About Agent Payments

After a year building infrastructure for the Agent economy, engaging with major players like Stripe, Visa, and Coinbase, the author shares a sobering analysis of the current state of Agent payments. The core finding is a stark lack of genuine, immediate demand across most envisioned use cases. The article breaks down four key market segments: 1. **Agent-to-Merchant (Consumer Shopping):** For most product categories (e.g., clothing, electronics), conversational AI shopping is a step backwards from visual e-commerce interfaces. While agents excel at understanding needs, they can't replace side-by-side product comparison. Real merchant interest is defensive "Agent Engine Optimization," not driven by current customer demand. Potential exists for high-frequency, low-decision purchases (like food delivery) or navigating complex store UIs, but these require massive B2C distribution channels dominated by giants like Amazon. 2. **Agent-to-API (Developer Services):** Developers already have subscriptions and billing relationships for APIs (compute, data). Prepaid balances solve micro-payment issues for low transaction volumes. A deeper structural problem is that major SaaS vendors' business models rely on enterprise contracts, resisting granular pay-per-call pricing. While protocols like MPP and x402 serve the long tail of niche services, this market is small and developers are historically low-willingness-to-pay. 3. **Agent-to-Agent:** This remains largely theoretical with minimal transaction volume. While it represents a long-term bet on a fundamentally new transaction infrastructure (sub-second, micro-penny to million-dollar, multi-party settlements), it does not constitute a present market. 4. **Agent-to-Finance:** This is the only category with existing, paying demand. Integrating AI into financial workflows (trading, portfolio management) is a natural evolution and enables new capabilities like autonomous rebalancing. However, competition favors established, regulated institutions. The "real problem" is not moving money between agents, but the broader challenge of **coordination**—orchestrating work between agents and humans, verifying outcomes, and settling results. Payment is just one component of settlement, which is itself part of coordination. Companies that solve the coordination layer will subsume payment, not the other way around. While well-funded incumbents build defensively for a long-term future, startups must find where the market is today—which, for the author's team, lies outside these four categories in an area of real, growing, and underserved activity.

It Took Me a Year to See the Hard Truth About Agent Payments

**Title: It Took Me a Year to See the Hard Truth About Agent Payments** Over the past year, I've worked on infrastructure for the Agent economy, engaging with major players like Stripe, Visa, Coinbase, and numerous startups. The findings reveal a stark reality: genuine, widespread demand for Agent-based payments does not yet exist. **Key Observations:** * **Agent-to-Merchant (Shopping):** The user experience for AI shopping often falls short, especially for visual product discovery. While AI excels at understanding needs, conversational interfaces can't yet replace browsing and comparing multiple products visually. Current merchant interest is largely defensive ("Agent Engine Optimization") for a future that hasn't arrived. High-frequency, low-friction purchases (like food delivery) are potential fits, but lack open APIs and face high AI inference costs. Simpler, more affordable, or cross-language interactions for complex UIs are a niche opportunity but require massive consumer distribution to scale. * **Agent-to-API (Developer Tools):** Developer payment needs for APIs (computing, data, models) are already met through subscriptions and prepaid credits. The core challenge is not payment friction but supplier economics: most large SaaS providers prefer enterprise contracts over micropayments for API calls. Protocols like MPP and x402 suit the long-tail of smaller services but cater to a developer market historically reluctant to pay for these tools. Major infrastructure needs at the top of the stack are already being addressed. * **Agent-to-Agent (Machine Commerce):** This is a long-term vision with almost no current transaction volume. While a future with high-speed, high-frequency, multi-party machine-to-machine transactions would require novel infrastructure, it remains theoretical. The market is not here yet. * **Agent-to-Finance:** This is the only category with clear, present demand. Financial professionals and DeFi users already pay for tools, and AI augmentation is a natural evolution. Autonomous AI agents can enable entirely new financial strategies. However, competition is fierce from established, regulated incumbents who can more easily layer AI onto their existing products. **The Core Insight:** Companies, especially giants with long time horizons, are building defensively for a potential future of mass machine commerce. For them, early investment is a low-cost hedge. For startups, the current market reality is different. The primary challenge isn't just moving money between agents (payments). The larger, unsolved problem is **orchestration** – coordinating work between agents and humans, verifying outcomes, and then settling. Payment is just a part of settlement, which is just a part of orchestration. Companies that solve the orchestration problem will subsume payments, not the other way around. After a year of building, we see the real, growing, and underserved market opportunity lies in this broader domain of orchestration.

Claude Opus 4.8 Finds a $4.5 Billion Bug: The AI Era is Mass-Producing Hackers

A researcher discovered a critical "infinite mint" vulnerability in the Zcash cryptocurrency's Orchard protocol using Claude Opus 4.8, leading to a swift fix but also a 50% market drop, erasing billions in value. This incident highlights a new era where powerful, accessible AI models are dramatically lowering the barrier to finding software vulnerabilities. Previously, the security community feared specialized models like Claude Mythos Preview, capable of finding decades-old zero-day exploits. The Zcash case, however, involved a publicly available, general-purpose model. This shift makes advanced security auditing—and attack capabilities—accessible to far more people, not just experts. The mass democratization of vulnerability discovery brings a dual challenge: a flood of low-quality, AI-generated false reports that overwhelm maintainers, and the real, rapid uncovering of deep, dangerous bugs. Open-source projects, often understaffed and unfunded, are particularly vulnerable to this "attention DDoS." The article cites examples like curl shutting down its bug bounty program due to the unsustainable workload. Our perceived digital safety has often been luck, relying on the high cost and effort required to find deeply hidden flaws in complex systems, as seen with historical vulnerabilities like Heartbleed or Baron Samedit. AI changes this cost structure, effectively "mass-producing flashlights" to illuminate every corner of our codebase. While large companies operate extensive security chains involving external white-hat hackers and massive defensive operations, the global cybersecurity workforce faces a severe shortage, especially of experienced personnel capable of analyzing complex threats and coordinating fixes. The core dilemma emerges: AI makes *finding* bugs cheap and scalable, but *fixing* them remains a slow, expensive, and human-intensive process. The article concludes that AI won't destroy the internet but acts as a bright light, revealing that our digital existence is not inherently secure but is precariously maintained by ongoing human effort. The true cost in the AI era may not be discovery, but whether there will be enough people left willing and able to do the hard work of repair.

Codex Goal Mode Usage Guide: How to Make AI Continuously Pursue a Specific Objective

"Codex Goal Mode: How to Make AI Work Continuously Toward a Specific Goal" OpenAI's Codex "goal mode" (/goal) transforms the AI from a reactive code assistant into a proactive execution agent capable of working autonomously for hours or even days to achieve a defined objective. To maximize its effectiveness, follow these key principles: 1. **Define Clear, Verifiable Exit Criteria:** The goal prompt should be a concise, measurable success condition, not a lengthy specification. Use quantifiable metrics like "reduce build time by 30%" or "achieve 100% test parity." 2. **Provide Initial Guidance and Tools:** Direct Codex toward likely problem areas and specify available tools (e.g., browsers, testing environments) to prevent it from exploring unproductive paths. 3. **Enable Progress Measurement:** Equip Codex with ways to track advancement, such as creating comparison tools for visual tasks or evaluation sets, ensuring it can gauge its own progress. 4. **Use a Realistic Execution Environment:** For tasks like performance optimization, provide access to environments that closely mimic production (e.g., similar configs, databases) to yield valid results. 5. **Be Cautious with Visual Goals:** Avoid vague "pixel-perfect" instructions. Instead, supplement visual references with functional checklists or design system specifications to prevent Codex from obsessing over minor details. 6. **Implement Progress Tracking:** For long-running tasks, have Codex commit code to draft PRs, update progress documents, or send Slack updates to maintain visibility into its work. 7. **Review and Consolidate Results:** Once the goal is met, instruct Codex to review its work, clean up ineffective experimental code, and reflect on what strategies succeeded or failed. Ultimately, using goal mode shifts the developer's role from writing prompts to managing a persistent engineering agent—defining objectives, establishing metrics, configuring environments, and conducting final reviews.
