蓝盒子的背后是 Bitmap Tech 团队，除了 BRC-420 协议，他们还推出了 Bitmap.Game（Bitmap 元宇宙）和 Recursiverse（基于递归协议的产品矩阵）。Bitmap 的市值最近从 300 万美元飙升至最高 2.9 亿美元，持币地址达到 3 万+，与蓝盒子一样，成为 Ordinals 生态备受关注的项目之一。

Bitmap Tech 团队在本周推出了比特币二层解决方案 Merlin Chain 的测试网，并在采访中透露其主网也将于 2024 年 2 月上线。本文旨在通过梳理 Merlin Chain 的公开信息，还原其愿景和解决路径。

旨在成为比特币二层网络的领军者

比特币一层网络的交易量在 Ordinals 生态的崛起下迅猛增长，然而设计时未充分考虑数据密集型交易，导致比特币网络拥堵不堪。为解决这一问题，近期涌现了众多比特币扩容方案，从需要自我保证安全的侧链到 DA 基于比特币一层网络的 Rollup，讨论纷纷。

在这众多方案中，以 EVM 侧链结合跨链桥的解决方案成为了立即可实施的方案，并在短期内成为比特币二层网络的标配。Bitmap Tech 团队深耕比特币生态多年，迅速投身到二层网络的开发中，推出了 Merlin Chain。

值得注意的是，改善一层网络的拥堵和降低交易手续费只是 Merlin Chain 要解决的问题之一。该团队正着眼于“比特币网络中新增用户数极少”这一更为深刻、复杂的问题。

Merlin Chain 的目标不仅仅是改善比特币一层的交易环境，更是在二层引入更多原生的应用。通过在二层实现对一层资产、协议和用户生态的赋能，比如基于 Bitmap 构建用户可轻松进入的元宇宙、基于 BRC-420 构建 DeFi 协议以最大化释放其图币二象性，来放大比特币生态整体的资产潜力。

ZK-Rollup 技术集成与资产安全保障

在技术实现路径上，Merlin Chain 采用了 ZK-Rollup 技术，将大量的交易证明压缩成一个简单的校验和，从而降低 DA 上链成本。二层的 sequencer 节点负责收集和批量处理交易，通过 zkEVM 生成压缩后的交易数据、ZK 状态根以及 Proof 证明。

压缩后的交易数据和 ZK Proof 将通过去中心化 Oracle 网络上传到比特币一层的 taproot 中，面向全网公开，以确保透明度和公正性。

其中，去中心化 Oracle 网络节点将会被要求质押 BTC，以保证其不会做恶。用户则可以基于压缩数据、ZK 状态根和 ZK Proof 发起对 ZK-Rollup 的挑战。成功挑战将导致回滚到上一验证通过状态，并罚没 Oracle 节点的锁仓资产，确保系统的安全性和可信度。

通过这些技术模块的整合，Merlin Chain 有望构建一个高效、安全、原生比特币的二层解决方案。

引领原生比特币生态的整合与扩张

除了强大的技术实力之外，Merlin Chain 与其他 Layer 2 项目的不同之处还在于，团队极为注重“比特币原生”，希望最终能为比特币的发展做出贡献。因此，作为服务比特币生态的第一步，团队通过账户抽象协议，成功实现了比特币钱包在 EVM 链上的集成。

在 Merlin Chain 上，原生比特币生态系统的用户可以继续使用他们的比特币钱包，在一层和二层网络之间自由切换，还能够体验比特币与其他资产之间的无缝互换。与此同时，之前从未接触过比特币的以太坊生态系统用户也可以使用他们熟悉的 EVM 钱包，例如 MetaMask，来进行交互，支付稳定币或以太坊、BNB、MATIC 等 EVM 系代币。通过这种方式，Merlin Chain 成功降低了比特币与以太坊两个生态系统用户之间的互动门槛，有望为比特币生态系统带来新的用户增长和活跃度。

除此之外，Merlin Chain 还支持 BRC-20、BRC-420、Bitmap、Atomicals 等铭文协议。用户可以通过跨链桥将这些原生资产转移到 Merlin Chain，甚至可以在 Merlin Chain 上以更低的价格和至少三倍的交易速度铸造比特币一层的铭文。

目前，Merlin Chain 已经公布了的生态伙伴涵盖了 DEX、DeFi、游戏、社交等多个领域，预计在主网上线后将进一步扩大其生态规模。

坚守比特币原生信仰，践行去中心化治理

在代币经济方面，Merlin Chain 坚持对“比特币原生”的信仰，否定了使用以太坊资产作为比特币二层网络治理代币的构想，转而选择采用原生的 BRC-20 协议。作为对去中心化理念的遵循，Merlin Chain 的治理代币会根据链上用户的质押和活动情况，把绝大部分代币都释放给用户和社区。

The Impossible Trilemma Is Basically a Pseudo-Problem

The article argues that the core limitation of blockchain technology is not the scalability trilemma, but its fundamental lack of privacy, which acts as a barrier to institutional capital. It defines blockchain as a slow, expensive, shared computer whose primary value is "permissionlessness" (no administrator) and verifiable trust. While this is ideal for native financial assets like stable币, which now process trillions, two critical flaws remain for mainstream adoption: regulatory legitimacy and a default transparency that leaks all financial activity. The author contends that transparency is not a feature but a tax, quantified through MEV extraction, making the public ledger unusable for serious institutions. However, modern cryptography, specifically zero-knowledge proofs, now offers a solution: "provable privacy." This allows users to prove compliance (e.g., solvency, KYC) without revealing underlying data. This fusion of privacy and auditability resolves the transparency-compliant privacy-compliance dichotomy, enabling a purely upgraded system where transactions are verified but not broadcasted. Closing these flaws is presented as the essential bridge to onboard the next wave of trillions in capital.

The "Impossible Triad" Is Fundamentally a Pseudo-Problem

The article argues that blockchain's fundamental limitation is not the scalability trilemma (decentralization, scalability, security), which has been largely solved, but the lack of **privacy** and, until recently, clear **legitimacy**. Blockchain is described as a slow, expensive, globally shared computer whose core value is censorship resistance and verifiability. While ideal for native digital assets like money (e.g., stablecoins), its default transparency acts as a **tax**, exposing all transactions and enabling MEV extraction, which deters serious institutional capital. Simultaneously, its permissionless nature created regulatory ambiguity. The piece contends that **privacy** is the missing critical feature. It rejects the false choice between total transparency and complete anonymity. Modern cryptography (like zero-knowledge proofs) enables **compliant privacy**: users can prove facts (solvency, KYC status, compliance) without revealing the underlying sensitive data (specific holdings, identities). This preserves auditability for regulators and eliminates the leak of financial information. With recent regulatory progress (e.g., the GENIUS Act) addressing legitimacy, adding default, provably compliant privacy becomes a pure upgrade. It transforms blockchain from a costly, public ledger into a confidential settlement layer, finally bridging the gap to mainstream institutional and individual adoption of on-chain finance.

Optical Chips: Collective Capacity Expansion

The global optical chip industry is experiencing a massive wave of expansion driven by surging AI data center demand. Major players across the US, Japan, Europe, and China are aggressively investing to ramp up production capacity. In the US, Coherent is expanding its 6-inch Indium Phosphide (InP) semiconductor fab in Texas, supported by CHIPS Act funding and a $2 billion strategic investment from NVIDIA. Lumentum is building a new factory for InP optical devices, and Nokia is scaling its advanced photonic chip packaging and testing capabilities. NVIDIA's investments aim to secure future supply of critical lasers and optical interconnect products for AI infrastructure. Japan's JX Advanced Metals, a leading InP substrate supplier, plans a multi-billion yen investment to increase its capacity 7-10 times, strengthening its grip on the crucial upstream materials market. In Europe, IQE and Tower Semiconductor settled a patent dispute and signed a multi-year InP epitaxial wafer supply agreement, highlighting that next-generation silicon photonics platforms will integrate high-performance InP components. STMicroelectronics and Sivers Semiconductors are also expanding silicon photonics production and partnerships. China is rapidly building out its domestic supply chain. Dongshan Precision's subsidiary, Source Photonics, announced a $12 billion project to expand optical chip and module production. Companies like Sanan Optoelectronics and Yunnan Germanium are scaling up InP chip manufacturing and substrate production, moving towards vertical integration from materials to modules. While debate continues around the exact future architecture—whether CPO (Co-Packaged Optics), NPO, or pluggables will dominate—analysts like Morgan Stanley argue the underlying driver is unchangeable: the explosive growth in bandwidth demand. This will inevitably increase the volume of optical engines, lasers, and related content per GPU, regardless of the final technical path. The competition for "more light" in the AI era has intensified into a global, full-chain capacity race.

Stablecoins Finally Find Real Yield: An In-Depth Look at On-Chain Reinsurance Re | A Conversation with Re Founder Karan Saroya

Stablecoin Real Yield Found: A Deep Dive into On-Chain Reinsurance with Re's Karan Saroya As stablecoin supply exceeds $170 billion, the search for sustainable, non-speculative yield intensifies. Re, an on-chain reinsurance platform, provides an answer: connecting stablecoin capital to the trillion-dollar traditional reinsurance market. Re operates as a regulated reinsurer, accepting stablecoin deposits as collateral to back US insurance companies. These insurers pay premiums, generating yield that flows back to on-chain depositors. Currently supporting 35 insurers and underwriting $500 million, Re projects scaling to over $1 billion soon. Key insights from a Bankless podcast with founder Karan Saroya and investor Avichal of Electric Capital: 1. **Uncorrelated, Real-World Yield:** Re offers stablecoin holders access to reinsurance returns (targeting 12-14%+), an asset class entirely separate from crypto or equity markets. 2. **Operational Efficiency via Smart Contracts:** Re replaces traditional, labor-intensive capital fundraising with smart contracts, allowing a ~12-person team to compete with industry giants. 3. **Regulatory Leverage:** For every $1 of collateral, regulations allow backing $5-7 in written premiums. This leverage amplifies returns from the underlying risk-free rate. 4. **DeFi Integration:** Depositors receive receipt tokens, which can be used in protocols like Morpho for "looping," potentially pushing yields to 18-20%+. 5. **The "DeFi Mullet" Model:** A compliant front-end (regulated reinsurer) paired with a decentralized back-end (smart contracts, DeFi capital markets). 6. **RE Governance Token:** Modeled on Lloyd's of London, the token governs the central capital pool's allocation, counterparty acceptance, and parameters. 7. **Real Economic Impact:** Capital funds real-world productivity (factories, clinics, businesses) via insurance, moving beyond crypto's internal loops. The discussion highlights a pivotal moment: DeFi's supply-side infrastructure is now met by real demand for productive yield, potentially kickstarting a flywheel where vast on-chain stablecoin capital seeks these real-world returns.

1996 or 1999? Walsh's First Test is 'How to View AI'

"1996 or 1999? Wall's First Big Test Is 'How to View AI'" Federal Reserve Chairman Wall's initial challenge is not whether to raise or cut rates, but a more fundamental judgment: what kind of boom is the current AI boom? This will determine the Fed's policy path and define his legacy. Economics is split between two opposing views, according to reporter Nick Timiraos. One sees imminent productivity gains that will increase supply and cool inflation, allowing the Fed to hold steady. The other argues that while productivity benefits are distant, demand shocks are here now, and waiting for data confirmation risks missing the intervention window, forcing sharper rate hikes later. Wall has signaled a leaning toward the first view, echoing 1996-era Alan Greenspan, who embraced strong, productivity-driven growth without fear of inflation. However, Wall faces a different macro environment than Greenspan did, with tariff pressures, expanding fiscal deficits, and diminishing globalization benefits, which could force more significant inflation pressures even if AI benefits materialize. Wall's logic, expressed before taking office, is that AI-driven productivity gains won't show in official data for years. If the Fed waits for confirmation, it might mistakenly tighten policy and choke off the very growth that could suppress inflation. This argues for using forward-looking narratives over lagging data. Chicago Fed President Austan Goolsbee presents a key counter-argument. He distinguishes between expected and unexpected productivity booms. A widely anticipated boom, like the current AI wave, can cause people to spend future wealth gains in advance, overheating the economy before productivity actually rises, thus requiring preemptive rate hikes. He cites rising costs for AI data centers as evidence of such overheating. Fed Governor Christopher Waller offers a rebuttal to Goolsbee, noting the "expected spending" mechanism only works if people can borrow against future income, which many households cannot do due to borrowing constraints. Wall also faces a paradox related to his desire to reduce the Fed's use of "forward guidance" (pre-announcing policy moves). This practice was established in 1999 when Greenspan began signaling hikes to avoid market shocks. If the economy follows a less optimistic path, Wall may be forced to choose between using the guidance he wants to abolish or risking market volatility by staying silent. The ultimate question defining Wall's first major test remains: Is this 1996 or 1999?
