Dialogue with Jia Hang | Looking Back at Two Decades of Chinese Payment Going Global

**Summary: A Conversation with Jia Hang on Two Decades of China's Payment Globalization** Jia Hang, a veteran with over twenty years in payments, reflects on China's attempts to build a global payment network through three key phases: UnionPay (card networks), Alipay+ (digital wallets), and now, stablecoins. His journey began at UnionPay International, aiming to establish China's card network abroad. While successful in following Chinese tourists ("where Chinese go, UnionPay goes"), it struggled to achieve true global scale. The core lesson: card networks like Visa/Mastercard's unassailable advantage isn't just technical standards, but their deeply entrenched **governance and profit-sharing models** that create powerful network effects. Competing as the "same species" is nearly impossible. At Ant Group, he led Alipay+, a strategy to bypass card networks by interconnecting local e-wallets worldwide. While innovative, it faced a similar ceiling. Mobile QR payments and card swipes were essentially **the same species competing for the same pie**, lacking a disruptive value proposition for users or a sustainable new incentive model to replace the card networks' established flywheel. Today, at Singapore's DCS, Jia focuses on stablecoin-based payments. He argues stablecoins represent a fundamental shift. They are not competing with Visa for consumer payments but challenging the **traditional banking and account system for value movement**. Products like "U Cards" (stablecoin-linked payment cards) are transitional, leveraging existing card networks for acceptance while building new rails. The real potential lies in stablecoins enabling seamless, low-cost global value transfer, potentially reorganizing the financial infrastructure around **accounts rather than cards**. Jia believes stablecoin adoption for local retail payments, cross-border transactions, and as high-yield savings vehicles is becoming irreversible. This could gradually reduce reliance on traditional fiat channels, especially in regions with weak currencies or capital controls. The quest for the "next global payment network" continues, now centered on whether stablecoins can successfully bridge Web2 and Web3, establish new governance, and create compelling user value beyond mere cost reduction.

Circle's Stock Price Plunges 76%, Hong Kong Dollar Stablecoin Set to Launch Within Two Weeks

Circle's stock price has plunged approximately 76% from its 2023 peak, reflecting a major market revaluation. Despite this, Circle President Heath Tarbert emphasized the company's focus on long-term execution and its dominant position with USDC's $73 billion circulation across 34 blockchains. The competitive landscape is intensifying. A new consortium-backed stablecoin, Open USD, is attempting to challenge incumbents by sharing reserve yields with partners. More significantly, Visa's new stablecoin platform, initially supporting Open USD while also being compatible with USDC, could erode Circle's network effects. In response, Circle is expanding into real-world payments through partnerships like the one with Japan's JCB. Separately, Tether (USDT) faces a two-year compliance window under new U.S. regulations, requiring it to adjust its reserve composition away from assets like Bitcoin and loans towards cash and U.S. Treasuries. Meanwhile, in Hong Kong, Standard Chartered-backed fintech firm Dian Dian is poised to launch a licensed HKD-pegged stablecoin (HKDAP), moving the industry into a phase where the real test is integrating licensed stablecoins into actual payment flows and corporate treasury systems. The sharp decline in Circle's stock underscores a broader shift: the stablecoin market is moving from a winner-takes-all dynamic to a multi-player competitive arena where execution, compliance, and real-world utility are becoming paramount.

Amidst Capital's Encirclement, Decentralization is the Sole Defense for Public Blockchains

In a landscape dominated by power and profit motives, the author argues that decentralization is not merely one desirable feature among many in blockchain design—it is the singular, non-negotiable defense against corporate and capital capture. The article adopts a Machiavellian, realist perspective on human institutions, positing that businesses will inevitably attempt to co-opt any valuable network to protect their profits and dominance. While external attacks like 51% forks are often discussed, the greater existential risk is internal capture—the gradual erosion of a protocol’s neutrality by vested interests, as seen historically with platforms like Visa and Google. The piece critiques permissioned chains, highly centralized “permissionless” layer-1s, and layer-2s without sufficient decentralization (e.g., single sequencers) as inherently vulnerable. These compromised systems, promoted by established financial players, are framed as delaying tactics to stifle truly open networks that threaten existing high-fee, inefficient business models. Real-world examples, such as closed enterprise consortiums that exclude competitors, illustrate how such systems cement oligopolies rather than foster innovation. The author concludes that while decentralized protocols like Ethereum are imperfect and costly to operate, they represent the only viable long-term equilibrium. In a market where value naturally flows to the most secure and neutral settlement layer, only maximally decentralized public blockchains can resist being subsumed by capital and powerful incumbents.

Who Decides the Rules of Bitcoin? BIP-110 Ignites Governance Debate

Bitcoin's governance is once again at the center of a heated debate, this time ignited by BIP-110, the "Reduced Data Temporary Softfork." This proposal aims to curb non-monetary data (like inscriptions and Runes) by introducing seven new consensus-layer restrictions over a year, such as limiting new output scripts to 34 bytes and restoring the OP_RETURN cap to 83 bytes. The controversy stems from BIP-110's fundamental shift: it moves the battle against "spam" from node relay and miner policies to the consensus layer, rendering currently valid transactions invalid. Supporters, arguing that default policy governance has failed (highlighted by Bitcoin Core v30's relaxation of OP_RETURN limits), see this as necessary to protect node resources and Bitcoin's monetary focus. Opponents, led by figures like Michael Saylor and Adam Back, warn it dangerously centralizes governance. Saylor listed 110 reasons against it, criticizing its low 55% miner activation threshold and potential for chain splits. Back emphasized Bitcoin's "permissionless" ethos, arguing no single group should impose value judgments via consensus rules. Further complicating matters, technical critiques suggest BIP-110 may be technically circumventable, and a "BlockSlop" vulnerability in its upgrade path poses a consensus risk. The debate has drawn in diverse stakeholders: miners (with pools like Ocean signaling support and Foundry polling clients), node operators (like Bitcoin Knots), and new players like corporate treasury holder MicroStrategy (Saylor), whose market influence adds a novel dimension. Ultimately, BIP-110 acts as a governance stress test, exposing the unresolved question: who decides Bitcoin's rules? It pits the authority of miners, node operators, developers, and capital holders against each other, with each side claiming to defend Bitcoin's core principles of neutrality and security.

Who Decides Bitcoin's Rules? BIP-110 Ignites Governance Debate

Title: Who Decides Bitcoin's Rules? BIP-110 Ignites Governance Debate A new technical proposal, BIP-110 (Reduced Data Temporary Softfork), has sparked a fundamental governance debate within the Bitcoin community. It aims to impose new consensus rules for one year to limit non-financial data (like inscriptions and Runes) on-chain, moving beyond simple node and miner policy filters to invalidate currently valid transactions. Supporters argue that default policies have failed due to workarounds, necessitating consensus-layer changes to protect Bitcoin's core monetary function from data spam. Critics, including Michael Saylor and Adam Back, contend this dangerously centralizes judgment, undermines permissionlessness, and sets a risky governance precedent. They advocate for market-based solutions like fees or Layer 2s instead. The debate exposes deeper tensions: miners are divided on activation; node operators assert their sovereignty; Bitcoin Core developers influence defaults without direct accountability; and large corporate holders like MicroStrategy now wield narrative influence. Technically, BIP-110 may not fully block data and carries a disclosed consensus bug risk. Ultimately, BIP-110 acts as a stress test, forcing the community to confront the unresolved question: who legitimately decides what Bitcoin is and how it evolves, amidst competing claims from miners, nodes, developers, and capital holders.

Zcash's New Node Zakura Goes Live: Privacy Payments Can Reach 50,000 TPS, Aiming to Rival Visa and Mastercard

Zcash, a privacy-focused cryptocurrency, has launched a new full node software called Zakura version 1.0.0. Developed by Zcash co-founder Sean Bowe and Dev Ojha, with private ZEC donations, its goal is to enable Zcash to process over 50,000 transactions per second (TPS)—matching the scale of Visa and Mastercard—while maintaining full transaction privacy and verifiability. This addresses a key bottleneck, as Zcash currently handles only about 1 private transaction per second. Zakura is a fork of the Zcash Foundation's Zebra node. It features chain pruning and snapshots, reducing disk usage and allowing new nodes to sync in under two minutes. It also offers compatibility with the legacy `zcashd` client interface. The scalability challenge stems from the large data size of privacy proofs. Bowe's Tachyon project aims to use recursive proofs to reduce consensus-layer data needs from ~500 MB/s to ~100 MB/s. For wallet scalability, Valar Group is researching Private Information Retrieval (PIR) tech to allow wallets to fetch their data privately. Zakura supports fast block propagation and the upcoming "Ironwood" network upgrade (NU6.3), scheduled for activation around July 28th. Ironwood was created to contain a critical inflation bug discovered in the Orchard shielded pool in May 2024. The fix uses "turnstiles" to trap any counterfeit ZEC created during the vulnerability period within the shielded pool, preventing it from entering circulation and restoring supply integrity.

Replicating the "DeepSeek Moment"? Wall Street Unanimously Says: Kimi K3 Instead Strengthens Computing Power Demand

Title: Wall Street Sees Kimi K3 as a Catalyst for Compute Demand, Not a "DeepSeek Moment 2.0" Summary: Following the release of Moonshot AI's powerful open-source model Kimi K3, initial market reaction mirrored the "DeepSeek moment" that sparked a sell-off in compute stocks earlier in 2025, fearing reduced demand for AI infrastructure. However, major Wall Street banks including UBS, Nomura, BofA, and Citi argue the opposite: K3 will accelerate, not weaken, demand for compute, memory, storage, and networking. Their analysis centers on K3's specifications—2.8 trillion parameters, 1M token context, and MoE architecture—which represent a "scale" story rather than a pure "efficiency" one like DeepSeek R1. These features increase pressure on inference, memory (especially KV cache), and storage. Analysts invoke Jevons Paradox: as high-quality models become more affordable (K3 is cheaper than top closed models but not the cheapest), usage and token volumes expand, ultimately increasing total compute consumption. The reports highlight that competition will force leading US AI labs (OpenAI, Anthropic, Google) to invest more in training and iteration to maintain their edge. Furthermore, the rise of capable open-source models like K3 is expanding the global AI developer ecosystem, with Chinese models now accounting for over 45% of developer traffic. Key beneficiaries identified across the AI infrastructure chain include memory/storage players (e.g., Micron, Samsung), compute leaders (Nvidia, TSMC), networking suppliers (due to "super-node" cluster needs for deploying K3), and cloud platforms (e.g., Alibaba) that host diverse model ecosystems. The consensus is that stronger open-source models are an entry point for the next wave of infrastructure demand diffusion, provided workload growth outpaces efficiency gains.

Prediction Markets Witness $200 Million in Suspicious Insider Trading Over Six Months, Who's Reaping the Profits?

Prediction markets are booming, with monthly trading volume exceeding $210 billion as of 2026. However, a Bloomberg investigation analyzing data from August 2025 to June 2026 reveals a parallel surge in suspicious trading, totaling roughly $200 million in the first half of 2026 on Polymarket alone. These potentially illicit trades are concentrated in geopolitical and military events, with 57% of the highest-earning wallets created less than 24 hours before trading. The analysis, using AI-driven platform Polysights, found profits are highly concentrated: the top 1% of wallets captured over half the gains. A significant portion (71%) of funds for marked trades originated from U.S.-regulated crypto exchanges, despite Polymarket's ban on U.S. users. Traders are increasingly using coordinated clusters of wallets and focusing on smaller markets to avoid detection. Two major criminal cases highlight the risks: a U.S. Army sergeant was charged for using classified information on a Venezuela operation to profit nearly $410,000, and an Israeli reservist allegedly leaked details of an Iran strike for a $128,400 gain. Regulatory scrutiny is intensifying. The CFTC is investigating Polymarket, congressional bills aim to ban insiders from trading, and major firms like Goldman Sachs have restricted employee participation. In response, Polymarket has updated its rules against insider trading and provided wallet data to authorities. The core challenge remains distinguishing between skilled research and trading on non-public information in a market designed to price such knowledge.

Trump Backs Down on Ethics Provision, as 'CLARITY Act' Enters Senate's Critical Window

On July 21st, sources report President Trump has agreed to include ethics provisions in the *CLARITY Act*, a major digital asset market structure bill, clearing a key obstacle after months of negotiation. The bill, which has already passed the House, aims to establish federal regulatory clarity for crypto by defining SEC and CFTC roles. The text is expected imminently, with a narrow window for Senate passage before the August recess. However, passage remains uncertain due to potential Democratic opposition over the ethics rules and the absence of key Republican senators. The ethics clause, a major sticking point, seeks to restrict federal officials, including the president, from profiting from digital assets while in office. This directly addresses controversies around Trump's own crypto holdings. While industry lobbyists urge Congress not to let ethics derail the broader bill, several Democratic senators have demanded stricter provisions covering family members and stronger consumer protections. Amid this legislative push, on-chain data shows significant Bitcoin accumulation by large holders ("whales") in recent weeks. After extended outflows, U.S. Bitcoin and Ethereum spot ETFs have seen two consecutive weeks of net inflows. Major corporate holders like Strategy and Metaplanet continue to accumulate or hold significant Bitcoin reserves. Notably, BitMEX co-founder Arthur Hayes recently made substantial Ethereum purchases, expressing a view that while AI is absorbing market liquidity, crypto markets have room for a rebound.
