Gate News message, April 23 — Ronin, a gaming blockchain, will migrate from an Ethereum sidechain to Ethereum Layer 2 on May 12. The migration will be triggered at block height 55,577,490 and will transition Ronin to OP Stack. The mainnet will experience approximately 10 hours of downtime, from 11 a

Gate News message, April 22 — Vitalik Buterin stated during a discussion with Xiao Feng that applications need to consider what Ethereum mainnet lacks. Layer 2 solutions should focus on applications that are not already available on the mainnet, rather than duplicating existing functionality. Buter

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.

Gate News message, Scroll_ZKP experienced a significant TVL decline from $232.7M to $23.19M within two days (April 7-9), following ether_fi's migration to Optimism. Data shows that 5 out of the top 10 blockchains with the largest TVL drops over the past 30 days are Ethereum Layer-2 networks.

Gate News message, April 21 — Security researcher Doyeon Park disclosed a critical 0-day vulnerability (CVSS 7.1) in CometBFT, the consensus layer of Cosmos, according to a post on X. The flaw could cause network nodes to stall during block synchronization, disrupting system operations, but cannot d

Institutional-scale stablecoins require a mature compliance and risk-management settlement layer; banks must trust blockchain to handle legal custody and compliance, with OSL pursuing licensed, AI-enhanced control layers for efficient settlement. Abstract: Eugene Cheung at Money 20/20 Asia argues that scaling stablecoin payments to institutional levels hinges on a licensed, AI-enhanced control layer and a mature compliance and risk-management settlement layer to ensure effective handling of legal, custody, and settlement risks. This underpins OSL’s strategy for institution-grade infrastructure and aims to build an operationally robust system that can meet complex regulatory requirements.

Between 07:15 and 07:30 (UTC) on 2026-04-19, the ETH spot price fluctuated in the 2298.13 to 2322.69 USDT range, with an amplitude of 1.06% and a return of -0.76%. During this period, market attention increased; the sharp drop in price triggered widespread user focus, along with a clear surge in trading volume within a short time, indicating a sudden escalation in liquidity pressure. The main driver behind this deviation is that on-chain whale accounts actively sold ETH to repay DeFi platform borrowings in order to avoid forced liquidation. Based on on-chain tracking and fund-flow monitoring, from April 18 to 19, more than 42,000 ETH per-transaction large transfers were rapidly sent into a certain mainstream exchange, and at the same time there was a sharp spike in net inflows to the exchange. This concentrated sell pressure directly weakened spot market prices. Under proactive deleveraging behavior, selling pressure was released in the short term, creating a sudden market shock. In addition, during the period of price deviation, the ETH derivatives market saw a significant rise in passive liquidation volume, especially as leveraged long positions encountered strong liquidations during the price decline, further increasing supply pressure in the spot market. Meanwhile, ETH spot ETF funds continued to see net outflows; in mid-April, there were multiple days with single-day outflows exceeding $40-50M, with the largest single day reaching $200M. This reflects a warming of short-term institutional risk-avoidance sentiment, which led to a deeper shift downward in buy-side liquidity depth. The launch of a new public chain ecosystem also attracted some ETH liquidity migration, further weakening the capital protection layer of the mainnet. Multiple structural feedback effects amplified the downside move. At present, leverage risk in the ETH market remains prominent. Some whales still have large borrowings outstanding; if the price continues to move downward, potential liquidation risks may flare up again. ETF fund flows, on-chain large transfers, and capital-attraction moves tied to the new-chain ecosystem all need close monitoring. With increased short-term volatility risk, it is recommended to watch key support zones, exchange net inflow indicators, and DeFi on-chain liquidation dynamics in order to promptly grasp the latest market signals.

Ethereum experienced its highest quarterly transaction volume in Q1 2026 with over 200 million transactions, marking 43% growth from the previous quarter. Layer 2 solutions and stablecoin usage drove this surge, indicating a utility-focused adoption trend.

Sui, a Layer 1 blockchain project, aims to expand in South Korea by collaborating with financial institutions and technology companies. Key initiatives include developing a stablecoin pegged to the won and enhancing its developer ecosystem with the Move programming language.
