Japan's February tertiary industry activity index showed a monthly decrease of 0.4%, according to Jin10. This decline was slightly better than the anticipated drop of 0.5%. The previous month's index had recorded a significant increase of 1.70%, highlighting a notable shift in economic activity.

A recent survey conducted by the Bank of Japan reveals that Japanese households anticipate an average inflation rate of 11.4% over the next year. According to Jin10, the median expectation for inflation stands at 10.0%. This survey highlights the growing concerns among Japanese households regarding rising prices and their potential impact on the economy. The findings come amid ongoing discussions about inflationary pressures and economic policies in Japan.

LayerZero Labs 在 X 平台发文表示，4 月 18 日 KelpDAO 遭受攻击导致损失约 2.9 亿美元，初步判断攻击者为 Lazarus Group。攻击通过投毒 KelpDAO 去中心化验证网络（DVN）依赖的下游 RPC 基础设施实现，攻击者控制部分 RPC 节点并配合 DDoS 攻击诱导系统切换至恶意节点，从而伪造跨链交易。目前受影响 RPC 节点已全部下线并替换，DVN 已恢复运行。LayerZero 强调，此次事件仅限于 KelpDAO 的 rsETH 应用配置，未对其他资产或应用造成影响。KelpDAO 因采用单一 DVN 架构且未使用多 DVN 冗余机制，导致无法识别伪造消息。LayerZero 协议本身未出现漏洞，多 DVN 配置的应用未受波及。LayerZero 将推动所有单 DVN 配置项目迁移至多 DVN 架构，并已暂停为 1/1 配置应用提供签名与验证服务，同时正协助执法机构追踪被盗资金。

Crypto analyst Ansem has expressed concerns about Ethereum's position in 2026, suggesting it is less favorable than in 2023. According to NS3.AI, Ansem believes the Ethereum thesis has been weakening over the years. He attributes this to Solana's growing retail presence, Hyperliquid's dominance in perpetual futures, limited progress in rollup adoption, and the recent Aave rsETH exploit. Despite Ansem's perspective, other community members have contested his assessment, indicating differing opinions on Ethereum's future trajectory.

On April 20, LayerZero Labs released a statement regarding an attack on KelpDAO that occurred on April 18, resulting in a loss of approximately $2.9 billion. According to BlockBeats, the attack is believed to have been carried out by the Lazarus Group, specifically TraderTraitor, with ties to North Korea. The attackers compromised the decentralized verification network (DVN) by poisoning the downstream RPC infrastructure, controlling some RPC nodes, and using DDoS attacks to redirect the system to malicious nodes, thereby forging cross-chain transactions. All affected RPC nodes have been taken offline and replaced, and the DVN is now operational again. LayerZero emphasized that the incident was limited to KelpDAO's rsETH application configuration and did not impact other assets or applications. The vulnerability arose because KelpDAO used a single DVN (1/1) architecture, lacking the redundancy of multiple DVNs as officially recommended, which would have provided independent verification nodes to detect forged messages. LayerZero clarified that its protocol did not have any inherent flaws, and applications configured with multiple DVNs were unaffected, indicating no systemic contagion risk. LayerZero announced plans to expedite the migration of all projects using single DVN configurations to a multi-DVN architecture and has suspended signature and verification services for 1/1 configured applications. The company is collaborating with global law enforcement agencies to investigate the incident and assist industry partners in tracking the stolen funds. LayerZero stated that the event highlights the importance of modular security architecture and serves as a reminder to the industry about potential security risks in RPC verification pathways.

Ethereum co-founder Vitalik Buterin outlined the future roadmap for Ethereum over the next five years during his keynote speech at the 2026 Hong Kong Web3 Carnival. According to Foresight News, Buterin emphasized Ethereum's dual core functions: serving as a 'public bulletin board' for applications to publish messages and ensuring user self-sovereignty, verifiability, and fair participation through shared digital objects controlled by code. The short-term protocol goals include five key areas: short-term scaling, the launch of ZK-EVM promotion, early post-quantum readiness, improvements in block construction pipeline, and privacy support. The next hard fork will incorporate several Ethereum Improvement Proposals (EIPs), such as parallelized block-level access lists, gas repricing, extended block verification time for ePBS, and node state synchronization improvements. EIP-8141 (account abstraction) will treat transactions as a series of calls, natively supporting smart contract wallets, gas payment, quantum-resistant signatures, and privacy protocols. Quantum-resistant signature algorithms, existing for 20 years, face efficiency challenges, with signature sizes reaching 2–3 KB and on-chain gas consumption around 200,000 gas. Solutions include hash-based signatures and 'lattice + vectorization' schemes. Mid-term goals focus on the state layer, which is more challenging to scale than the execution layer, requiring state tree optimization and exploring solutions that do not require permanent storage of all states. Long-term protocol goals include maximizing secure consensus (tolerating 49% node failure in synchronous networks and maintaining a 33% finality safety threshold in asynchronous networks), formal verification of all content (using AI-generated mathematical proofs), comprehensive quantum resistance, maximal simplicity, and forward-looking security even without the core developer team (via the walkaway test). Lean Consensus will merge the advantages of Bitcoin-style 'available chain' and BFT-style 'finality' mechanisms, offering quantum resistance and rapid finality (expected within 1–3 slots, approximately 10–20 seconds). By 2025, ZK-EVM is expected to achieve 'sufficient speed' for real-time EVM execution proofing; by 2026, it aims for 'sufficient security' with partial node usage (e.g., independent stakers); and by around 2028, ZK-EVM will become the primary method for chain verification.
