Base Azul is live on testnet with a May 13, 2026 mainnet activation target, the first independent network upgrade; it boosts security, performance, and developer experience via multi-proof, single execution client, and Osaka; no user action needed. Base announces Azul, its first independent network upgrade, now live on testnet with a May 13, 2026 mainnet activation target. The upgrade adds a multi-proof mechanism, designates base-reth-node as the sole execution client, and adopts the Osaka execution layer specification to stay aligned with Ethereum, with no user action required. Two more upgrades are planned for late June and late August, and Base Vibenet, a public development network for testing upcoming features, will launch mid-May.

Security researcher Doyeon Park disclosed a CVSS 7.1 zero-day in Cosmos' CometBFT causing potential node freezes during sync; vendor resistance, downgrades, and disclosure led to April 21 reveal; validators should avoid restarts before patch. Abstract: Security researcher Doyeon Park disclosed a critical CVSS 7.1 zero-day vulnerability in Cosmos' CometBFT consensus layer that could cause nodes to freeze during block synchronization, potentially affecting networks securing over $8 billion in assets. The vulnerability cannot directly steal funds. Park pursued coordinated disclosure beginning Feb 22, but faced vendor resistance to public disclosure and issues with HackerOne. The vendor downgraded a related vulnerability (CVE-2025-24371) to informational on Mar 6, prompting Park to release a network-level proof-of-concept before public disclosure on Apr 21. The advisory recommends Cosmos validators avoid restarting nodes until patches are released; nodes already in consensus may continue but restart and resync could expose them to attacks by malicious peers, risking deadlock.

A certain trading platform has been awarded a Money Services Business license by the U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) for its cryptocurrency asset services. The license authorizes the platform to conduct crypto-asset business in the U.S. and other jurisdictions. The license indicates that its anti-money-laundering and user protection standards are up to par, with KYC, funds tracking, and continuous monitoring already integrated. It has deployed a multi-node infrastructure, business segregation, and real-time alerting, while risk controls have been optimized to support high-concurrency trading. It also plans to expand into emerging markets through localization and multilingual services, bringing crypto trading into the international financial system.
