SpaceX's IPO Filing Reveals Musk's Symbolic Salary, CEO's Total Compensation Reaches $85.8 million

April 21 — Japan Securities Clearing Corporation (JSCC), a clearing arm of Japan Exchange Group, has launched a proof-of-concept (PoC) experiment with Mizuho Bank, Nomura Securities and Digital Asset to explore blockchain technology for Japanese Government Bond (JGB) management. Per a joint statement released Monday, the experiment will use the Canton Network to integrate existing systems across multiple institutions and test on-chain transfer and management of JGBs. Its goal is to evaluate the feasibility of enabling real-time collateral transactions while complying with relevant financial instrument and transaction laws. The PoC will also explore cross-border use cases involving central counterparties (CCPs), institutional investors and other market participants. JSCC noted the experiment is part of Japan’s Ministry of Finance’s broader "Payment Innovation Project." As overseas markets like the U.S. advance testing of similar infrastructure, advancing JGB collateral management

April 21st – During the “Decoding Web 4.0: When AI Agents Take Over On-Chain Authority” roundtable, MuleRun CTO Steven Hu dove into the “Agent Moat” topic, noting the traditional idea of an AI tech moat is quickly fading. The core driver? Faster convergence of model capabilities and exponential gains in development efficiency. Hu pointed out the performance gap between mainstream large models is narrowing rapidly—especially over the past year, when the capability gap between domestic and global models has shrunk significantly. Meanwhile, exploding coding capabilities have supercharged software development: features that once took weeks or months to build now take days. This means Agent frameworks and specific functional modules can be quickly reused or replicated via open-source tools, making product-level “feature moats” increasingly fragile. In this landscape, Hu argues Agents’ future core competitiveness will hinge on two pillars: 1. **Continuous high-frequency iteration*

On April 21st, per HyperInsight monitoring (https://t.me/HyperInsight), a whale address starting with 0x616 liquidated its $4.06 million BTC short position via a stop-loss order, with a liquidation price of $76,218. The transaction incurred a minor loss of roughly $2,614. Subsequently, the address re-entered the market above the liquidation price at $76,670 and opened a new BTC short position of 52.6 BTC—valued at approximately $4.03 million—indicating an intent to reinitiate a short position. Address: 0x616f5d5db5cf8d98a8554c84492bce764c7f09b1

On April 21, at the roundtable discussion *Decoding Web 4.0: When AI Agents Take Over On-Chain Governance*, Box—Developer Relations for Monad Foundation Greater China—delved into the “Agent Moat” topic. He noted that the technical barrier to building AI agents is currently fairly low: the so-called “moat” for AI agents hinges not on the product itself, but rather on a founder or team’s understanding of AI, their ability to steer it, and their external influence. He pointed out that many agent products today are built quickly using open-source code and off-the-shelf tools, slashing development timelines. It’s not unusual to launch a product in just a few hours—but this also means the product form is easily replicated. When cloud providers or major model vendors step in, they can often replicate or even outpace these offerings in a short time, causing early-stage startups to quickly lose their competitive edge. Box further emphasized that in this landscape, the survival logic for a
