Odaily news: The Zcash Foundation has announced the release of Zebra 4.5.1 version update to fix a consensus-critical security vulnerability and strongly recommends that all node operators upgrade immediately. The vulnerability, identified as GHSA-2prc-cj5x-4443, involves a sigops (signature operation count) counting error in P2SH transactions, which could lead to potential consensus fork risks. This fix corrects an incomplete patch in the previously released 4.5.0 version, which was just released yesterday.The Zcash development team stated that the issue stems from discrepancies in sigop counting logic between different implementations, which could cause nodes to produce different results when verifying transactions, thereby affecting consensus consistency on the chain. The fix resolves this by reverting and adjusting the Rust implementation logic to ensure alignment with the expected protocol behavior.The Zcash Foundation emphasized that there is currently no workaround for this issue, and upgrading to 4.5.1 is the only method to ensure nodes remain on the correct chain and avoid potential fork risks.
Bybit has officially launched its new “Hold USD1 to Earn Tokens” campaign. Users only need to complete Level 1 KYC verification and hold at least 1 USD1 in their Bybit account to share daily WLFI rewards—no subscription or lock-up required; rewards are earned simply by holding. The campaign begins on May 19, 2026, at 10:00 UTC. During the campaign period, users can earn up to a 20% annualized return and compete for a total reward pool of up to 45,000,000 WLFI—climbing the USD1 Holding Leaderboard. USD1 is a regulated stablecoin issued by World Liberty Financial, fully backed 1:1 by short-term U.S. Treasury securities and cash equivalents, and strictly pegged to the U.S. dollar. WLFI is the governance token of the World Liberty Financial ecosystem, enabling holders to participate in protocol governance and influence the ecosystem’s strategic direction. In this campaign, WLFI rewards will be distributed daily to USD1 holders on the Bybit platform. During the campaign, the system will take a snapshot of each user’s eligible USD1 balance once every hour—24 snapshots per day. WLFI rewards are expected to be credited to users’ main account funding wallets by approximately 06:00 UTC the following day.
Stani Kulechov, founder of Aave, stated that the next phase of the rsETH technical recovery plan has been completed, and Aave has restored the WETH loan-to-value (LTV) ratio on affected networks to pre-incident levels. Users can now once again use WETH for borrowing, collateralization, debt swapping, and other operations on Aave. According to Aave’s announcement, this restoration applies to the following Aave V3 deployments: Ethereum Core, Ethereum Prime, Arbitrum, Base, Mantle, and Linea.
According to data released by Glassnode on platform X, the relative unrealized loss of Bitcoin long-term holders (LTH) briefly reached approximately 15% in early April. Compared to levels exceeding 75% during historical deep bear market cycles, the impact of this market correction on long-term holders is notably lighter.The analysis points out that while recent price pullbacks have caused some paper losses, the overall pressure remains far below historical cycle lows, indicating that the current decline has not yet posed a substantive test to the conviction of long-term holders. Structurally, this adjustment is more characteristic of mid-term volatility rather than a full-scale cyclical capitulation event.
Coinbase has disclosed the integration of the trading protocol DFlow as its primary transaction router for the Solana ecosystem, enabling users to execute native value exchanges for spot trading and prediction markets on Solana. Coinbase stated that after introducing DFlow, the transaction failure rate for its Solana products dropped from approximately 1/30 to roughly 1/250, an 8-fold reduction. Additionally, the solution has expanded liquidity coverage, making previously untradeable small and mid-cap tokens due to "no liquidity" now tradable, and has optimized user execution prices.

WEEX Exchange has announced the upgraded return of its “Futures Mining” campaign—Phase V—running from May 1, 00:00 to May 31, 23:59:59 (UTC+8), live throughout the entire month of May. While retaining the core gameplay—“Trade to Mine, Earn More Fee Refunds with More Trading”—Phase V introduces enhanced rewards: the maximum fee refund rate has increased from 40% to 45%. During the campaign, users receive real-time fee refunds in WXT for every futures trade executed. Users can upgrade their Miner Level—and thereby unlock higher fee refund rates—via any of the following methods: accumulating futures trading volume during the campaign period, sharing the campaign and joining official communities, inviting friends to participate, or earning mining rewards totaling 3,000 WXT. Additionally, users may use WXT rewards earned from “Futures Mining” to participate in WE-Launch for free airdrops of popular new tokens, or stake WXT in WEEX’s Staking program to earn up to 2.5% APY.
The Zcash Foundation officially announced the release of Zebra 4.4.0, which addresses multiple critical consensus-level security vulnerabilities. All node operators are strongly advised to upgrade immediately. The vulnerabilities include a denial-of-service (DoS) flaw that could permanently halt the discovery of new blocks; a signature operation (sigop) counting error in block validation that may cause consensus divergence; abnormal handling of transparent transaction signature hashes; and a memory allocation amplification attack risk. The Zcash Foundation stated that some of these vulnerabilities could cause Zebra nodes to accept blocks rejected by zcashd, potentially triggering a chain fork. Without timely upgrades, nodes risk interruption of block discovery, consensus forks, and amplified resource consumption. No alternative mitigations are currently available.
The core AI suite of the FLOA ecosystem, FloaClaw, has been officially launched in full, simultaneously releasing a multi-scenario AI skills matrix. These features are only accessible to Agents of Level 3 and above.As the core AI tool of the FLOA ecosystem, FloaClaw's usage requires adherence to clear rules: Users need to recharge BNB to obtain compute power-tokens (tokens), with skill consumption increasing along with task complexity; subsequently, FloaClaw will continue to iterate and scale, unlocking more new AI skills and tool modules, while also advancing a creator dividend system. This will allow Agent creators to share in the compute power-token (token) revenue from user skill consumption, and support one-click exchange and withdrawal of BNB, thereby building a sustainable creator economy loop.FLOA is an intelligent Web3 Agent ecosystem platform on the BNB Chain, integrating core capabilities such as data analysis and on-chain automation. Featuring an open incentive mechanism, it serves both as a tool for user empowerment and an efficient growth engine for the Web3 ecosystem.
According to Cointelegraph, the European Central Bank (ECB) has endorsed the EU’s proposal to transfer financial market regulation—including oversight of crypto-asset service providers (CASPs)—from national regulatory authorities to a centralized EU-level regulator.
Crypto analyst Ali published a detailed analysis on X, arguing that rather than debating whether Bitcoin has hit its bottom, market participants should focus on whether the current volatility represents a “generation-defining entry opportunity.” Based on long-term trend lines, on-chain liquidity, and cost distribution metrics, Ali delineates the core “value range” for this cycle. On the support side, the UTXO Realized Price Distribution (URPD) shows a significant concentration of coins in the $63,111–$70,685 range, forming the current primary support zone; if price breaks below $63,111, the market may enter a liquidity vacuum. From a long-term perspective, Bitcoin is approaching the key upward trend line from the past decade (approximately $56,000–$60,000), a level historically associated with accumulation phases preceding major rallies.
