Abstract

The article "The Migration of Settlement Power: B18 and the Institutional Starting Point of On-Chain Banking" discusses how traditional finance relies on settlement—not just transactions—to determine ownership of funds. While transactions are instantaneous, settlement requires time, counterparties, and system confirmation, during which users do not fully control their funds. In contrast, early DeFi (decentralized finance) focused on trading and liquidity while avoiding the fundamental question of who defines settlement in the absence of banks. B18, built on Coinbase’s on-chain infrastructure and operating on Base, aims to address this gap by transforming blockchain into a system that handles time, accounting, clearing order, and finality—functions traditionally managed by banks. B18 is not a typical DeFi protocol but an attempt to decouple banking from institutions and encode it into executable rules. Its capital structure reflects this ambition, with support from Paradigm and Wintermute Ventures at the protocol level, GSR Capital for market liquidity, FuturePay for real-world payment integration, and Base Ecosystem Fund builders who design the rules for fund recording, profit recognition, and liquidation conditions. Together, these layers form a new on-chain financial order where code, not institutions, governs settlement—shifting the power dynamics of finance. B18 represents the starting point of this migration. (Note: This is a submitted article and does not re...

In the traditional financial system, what truly determines whether "money belongs to you" is not the transaction itself, but settlement. Transactions can be completed in an instant, but settlement requires time, counterparties, and system confirmation. During this process, the funds do not entirely belong to the user; they are temporarily held within the system.

Wall Street understands this well.

The banking system exists not because of transactions, but because of settlement and clearing. From SWIFT to clearing houses, from custodial institutions to central counterparties, the core of the financial system has never been liquidity, but the order of settlement. In the on-chain world, early DeFi chose to bypass this issue. They emphasized transactions, returns, and liquidity, but rarely touched upon a more fundamental question:

In the absence of banks, who defines settlement?

This is precisely the domain B18 is attempting to enter.


B18 is built on the on-chain infrastructure system promoted by Coinbase and runs on the Base execution layer.

In this system, blockchain is no longer just a transaction recording tool but begins to carry functions closer to the traditional financial system: time, accounting, clearing sequence, and finality.

B18 does not define itself as a DeFi protocol but attempts to answer a more fundamental question:

When banks are no longer institutions, how do settlement rules exist?

This question determines its capital structure. Unlike most crypto projects built around financing and valuation, B18's capital background presents a layered structure more akin to the financial system itself.

At the protocol and institutional level, B18 receives support from institutions such as Paradigm and Wintermute Ventures. These institutions have long been involved in the evolution of protocols within the Ethereum ecosystem. Their focus is not on short-term gains but on whether the on-chain financial structure can operate sustainably.


At the market level, B18 connects with institutions like GSR Capital. These participants form the foundational conditions of the on-chain market, enabling pricing, liquidity, and clearing to be validated in real environments rather than remaining theoretical.

Simultaneously, B18 introduces capital from the payment and financial infrastructure system (FuturePay). The existence of this layer holds deeper significance—it means on-chain systems are beginning to connect with the real-world settlement network. Stablecoins are no longer just assets but become units of settlement; on-chain protocols are no longer just applications but begin to assume systemic responsibilities.


At the ecosystem level, B18 operates依托 (Note: 依托 means relies on/operates based on, kept as is for context) the Base Ecosystem Fund and its network of developers. But more important than capital is another type of participant: builders.

These engineers and protocol designers from the Ethereum and Base ecosystems do not build products; they build rules.

They decide:

  • How funds are recorded
  • When returns are confirmed
  • Under what conditions清算 (liquidation/clearing) occurs

These questions, determined by banks and institutions in traditional finance, are being recoded on-chain.

Structurally, B18 is not a project but an attempt: to剥离 (strip/separate) the bank from the institution and transform it into an executable system of rules.

Its capital structure is therefore not just a source of funding but a deeper signal:

  • Protocol capital, representing the design of rules
  • Market infrastructure capital, representing price and liquidity
  • Payment system capital, representing settlement and connection to the real world
  • Builder network, representing the continuous evolution of the system

Together, these four elements constitute not a market, but an order.

In the traditional system, banks decide settlement; in the on-chain system, code begins to take over this duty.

As settlement migrates from institutions to protocols, the power structure of finance also changes.

And the position B18 occupies is precisely the starting point of this migration.

Sequoia Dialogue with Jensen Huang: Computing Model Undergoes a 60-Year Transformation; You Won't Be Replaced by AI, But You Will Be Dimensionality-Reduced by 'Those Who Master AI'

NVIDIA founder and CEO Jensen Huang, in a conversation with Sequoia Capital's Konstantine Buhler, argues that we are witnessing the most significant computing shift in 60 years—from retrieval-based to generative computing. Instead of just storing and retrieving data, future systems will generate highly personalized content (text, images, video) on demand, powered by massive "AI factories." Huang envisions a global "intelligence network" that will envelop the planet, following the historical patterns of energy and communication grids. He outlines a five-layer investment framework: 1) Energy, 2) Chips/Computers, 3) Infrastructure (data centers), 4) AI Models, and 5) Applications. He predicts this ecosystem will reach a scale of $20 trillion annually. Crucially, Huang pushes back against fears of AI-driven job loss. He distinguishes between specific "tasks" (e.g., typing, analyzing images) and overall "jobs" (e.g., CEO, radiologist). While AI automates tasks, it increases efficiency and demand for the higher-value problem-solving aspects of professions, thus creating more jobs and "up-leveling" careers. The real risk, he asserts, is not being replaced by AI, but being outperformed by someone who effectively leverages it. He urges everyone to embrace AI as a tool for augmented capability and innovation.

"I Don't Need a Better Model Anymore": A Panorama of AI Users Under a Reddit Hot Post

Titled "I Don't Need a Better Model Anymore": AI User Reactions on Reddit Anthropic recently released Claude Fable 5, its first publicly available 'Mythos'-tier model, achieving 80.3% on the SWE-Bench Pro benchmark and significantly outperforming its predecessor and competitors. However, a viral Reddit post titled "Claude Fable made me realize I don't need better models anymore" highlighted a growing user sentiment of "good enough." Top comments expressed "model fatigue," with users stating that earlier models like Opus 4.5/4.8 already sufficed for their workflows. High cost was a key concern, as Fable 5's API is nearly twice the price of Opus 4.8, with users questioning the return on investment and suggesting the field has hit a plateau. The most frequent complaint targeted Fable 5's stringent safety filters. Designed to intercept high-risk requests (e.g., cybersecurity), the system was perceived as overly conservative. Users reported frequent rejections for routine security-related tasks, leading to automatic fallbacks to the older Opus model. Paying users were particularly frustrated, feeling they paid a premium for a less usable product. Dissenting voices came from users with heavy, complex tasks. For workloads like high-energy physics simulations with thousands of code lines, Fable 5's improved long-context understanding and error detection represented a significant, worthwhile leap—described as moving from a "college player to an NBA starter." The debate underscores a divergence between benchmark performance and practical utility. For most users, current models meet their needs, making further advances relevant only for extreme use-cases. The discussion also raised concerns about a potential "Public AI Freeze," where the most powerful models (like the restricted Mythos 5) remain exclusive to enterprises and governments, while public offerings stagnate. The launch presents two report cards: one of technical excellence and another of user skepticism. Fable 5's ultimate reception may depend on Anthropic's ability to refine its safety filters and justify its cost for specialized, high-demand users.

When AI Traffic Surpasses Humans, How Do You Prove You're Human?

With AI-generated web traffic surpassing human activity, websites face a crisis as AI agents bypass ads, avoid clicks, and scrape data without generating revenue. This disrupts the ad-based internet economy, diverting traffic and reducing site visits. In response, sites are blocking AI crawlers and deploying traps like Cloudflare's "honeypot" pages. Traditional CAPTCHAs are now ineffective against advanced AI. The focus has shifted to behavioral biometrics—analyzing unique human patterns such as cursor movement, typing rhythm, and keystroke dynamics. Companies like IBM and BioCatch use this data to distinguish humans from bots, even detecting fraud through behavioral inconsistencies. Two competing approaches aim to verify human identity centrally. Sam Altman’s World (formerly Worldcoin) uses iris scanning to create unique credentials, though it faces privacy concerns and regulatory bans. Alternatively, cryptographic zero-knowledge proofs offer anonymous verification without revealing personal data, championed by Vitalik Buterin to avoid centralized surveillance. However, both systems have flaws. Centralized solutions risk biometric data misuse, while decentralized models may be exploited through identity rental markets in economically unequal regions. Despite challenges, the author favors cryptographic methods for preserving privacy over pervasive behavioral monitoring that permanently captures and controls personal biometric data.

2026 Landscape of Decentralized AI: Why is Blockchain the Inevitable "Antidote" for AI?

**The 2026 Landscape of Decentralized AI: Why Blockchain is the "Cure" AI Cannot Ignore** Decentralized AI addresses fundamental bottlenecks of centralized AI: scarce and expensive computational resources, excessive control concentration, unverifiable model outputs, and increasing difficulty in acquiring training data due to privacy and regulation. Blockchain offers a path to make intelligence open, verifiable, and economically accessible. The technical stack comprises three layers: 1. **Applications & Services**: The main crypto use cases are "Agentic Finance" (converting natural language into on-chain actions) and "Agentic Payments" for machine-to-machine commerce. Projects like Giza, Infinity Labs, Coinvest AI, and x402 (handling 173M+ transactions) are key players. 2. **Middleware**: This coordination layer enables agents to discover, identify, and transact. Notable projects include Gokite AI (specialized L1), Virtuals (an OS for the agent economy), and especially Bittensor—a network of specialized subnets forming competitive AI micro-economies. 3. **Infrastructure**: The capital-intensive layer providing raw resources. It includes decentralized compute (Akash, Render, Aethir), verifiable inference (Venice AI, OpenGradient), distributed training (Prime Intellect, Templar AI), decentralized storage (Filecoin, Walrus), and privacy/verification layers (Nillion, Arcium, Phala Network) using technologies like ZKPs, MPC, and TEEs. The outlook for 2026-2027 indicates AI demand outpacing infrastructure, with AI agents as a primary growth engine. Computation is becoming an asset class, with on-chain markets as its financial layer. Tokenomics is emerging as a structural advantage for coordinating capital, compute, and data in decentralized AI networks. While still early—with adoption uneven and revenue often trailing token incentives—projects like Bittensor, NEAR, and Virtuals demonstrate a shift from speculative narrative to a new model for coordinating intelligence.

a16z Crypto Partner: Cash Flow is the Moat

Cash Flow as the Moat: A Playbook for Crypto Founders Historically, the most enduring businesses have been built by positioning themselves within the "flow of funds"—facilitating the creation and transfer of value in a network and extracting a portion of it. Cryptocurrency is the first modern technology natively built for this purpose. For startups, failing to architect products and businesses to leverage these principles means missing a major opportunity. Blockchains are inherently network businesses. Each transaction settles on a shared ledger, and every new participant strengthens the underlying network for all. Well-designed network tokens amplify this by aligning users, developers, and validators around growing the network, with value flowing back to contributors in a transparent feedback loop. This model is not new; companies from railroads and Standard Oil to Google, Meta, and AWS have thrived by inserting themselves into critical flows of value (goods, attention, compute). Financial markets make it even clearer: firms like Visa and major market makers generate immense revenue not by predicting markets but by being in the path of transactions. The combination of fund flow and network effects creates one of the most durable business structures. The high margins in traditional finance (payments, custody, lending, FX) represent prime targets. Crypto founders have the opportunity to build the next version—programmable, instant, global, and natively in the flow of funds. The frontier extends beyond finance to areas like computing/GPUs, AI training data, energy, robotics, and space—markets without entrenched intermediaries, ripe for building new, efficient value rails on programmable infrastructure. Founders should ask: Are you in the flow of funds today? Does your revenue scale 10x with the value of activity on your platform? Where in your target market are profit margins highest relative to value created? The opportunity is clear: embed your startup into the new flows of value and let the network effects accumulate.
