Dolphin Network has announced its adoption of a Peer-to-Pool architecture to reuse idle GPUs, according to Foresight News. This system allows each model to operate within a GPU pool, with nodes randomly assigned tasks, eliminating direct buyer-seller bindings. Nodes receive POD token rewards from the protocol treasury based on the number of inference tokens processed. Users can purchase credits directly from the protocol using POD, ETH, BTC, USDC, XMR, and ZEC. All protocol revenue is allocated for market buybacks of POD, directly offsetting inflation. For instance, Dolphin charges users $0.7 per million tokens for Qwen 3.6 35B, which is lower than OpenRouter's $1. Of this, $0.5 is paid to nodes, generating a net buyback of $0.2. POD holders can stake their tokens in the xPOD treasury to receive automatic reinvestment dividends, daily inference quotas, and ecosystem subscription benefits. Node operators are required to stake POD bonds equivalent to four weeks of income, which are subject to forfeiture in cases of cheating. The reward multiplier mechanism can reach up to two times.

Bitcoin’s peer-to-peer network is experiencing a mysterious and unprecedented surge in node-related IP addresses, with daily unique addresses suddenly exploding from a long-standing range of roughly 30,000–60,000 to nearly 250,000 by May 2026 — a spike that has alarmed parts of the Bitcoin developer community.

RateX (RTX) is set to unlock approximately 1.23 million tokens on May 19 at 9:00 AM UTC+8. According to ChainCatcher, this token release is valued at around $1.71 million.

Quai Network is set to unlock approximately 43.02 million tokens on May 19 at 21:00 UTC+8. According to ChainCatcher, this token release is valued at around $1.2 million. The event is part of the network's ongoing token distribution plan.

Grayscale has filed an application to convert its existing Zcash Trust into a spot ETF, marking the first attempt to list a privacy coin ETF in the United States. According to ChainCatcher, this move comes as Multicoin Capital reveals its ongoing accumulation of ZEC since February. Co-founder Tushar Jain links the investment strategy to proposed U.S. wealth tax legislation, suggesting that increased government scrutiny of private financial holdings will drive demand for assets that offer regulatory shielding at a mathematical level. The application, however, raises institutional custody challenges. Approximately 30% of Zcash's supply is held in shielded address pools, a historical high, while ETF custody typically requires the use of transparent address pools to meet audit and proof-of-balance requirements. Previously, the SEC concluded a long-term review of Zcash in January 2026 without enforcement action, significantly reducing regulatory uncertainty.

According to the announcement from Binance, the platform will implement updates to the collateral ratio and Tiered Collateral Ratio for PM Pro under Portfolio Margin, effective from 2026-05-15 06:00 (UTC). The update is expected to be completed within approximately 30 minutes. The assets affected include UNI, ENA, RAY, APE, and ZEC, with collateral ratios being adjusted. For instance, UNI and ENA will see their collateral ratios decrease from 60% to 50%, while ZEC's collateral ratio will increase from 30% to 50%. In addition to these changes, Binance Futures will update the leverage and margin tiers for several USD-M Perpetual Contracts. This update is scheduled to be completed within approximately one hour. The changes will affect existing positions opened before the update, and users are advised to adjust accordingly to avoid potential issues. The leverage and margin tiers for contracts such as NAORISUSDT, ARCUSDT, MUSDT, and others will be revised. For example, the NAORISUSDT contract will see changes in leverage and maintenance margin rates across various position sizes, with leverage adjustments ranging from 1x to 20x depending on the notional value in USDT. Binance emphasizes that users should closely monitor the Unified Maintenance Margin Ratio (uniMMR) to prevent potential liquidation or losses due to the changes in collateral ratios. The platform advises users to stay informed about the updates to ensure smooth trading operations. These updates reflect Binance's ongoing efforts to optimize its trading environment and risk management protocols. Users are encouraged to review the updated trading rules and leverage guidelines to align their strategies with the new parameters.
