The Ministry of Agriculture and Rural Affairs held a symposium on the development of the live pig industry, calling for strict control of new production capacity! Live pig futures have shown a strong upward trend for five consecutive days—is this the early start of a new pig cycle, or a "last hurrah" under conditions of overcapacity? Click to read more.

BlockBeats News, April 20: LayerZero Labs released an incident report stating that on April 18, KelpDAO was attacked, resulting in a loss of approximately $290 million. The preliminary assessment attributes the attack to the Lazarus Group from North Korea, specifically TraderTraitor. The attack was carried out by poisoning the decentralized validation network (DVN)'s downstream RPC infrastructure. The attacker controlled some RPC nodes, coordinated a DDoS attack, and induced the system to switch to malicious nodes, thus forging cross-chain transactions. The affected RPC nodes have all been taken offline and replaced, and the DVN is now back online. LayerZero emphasized that this incident was limited to KelpDAO's rsETH application configuration and did not impact other assets or applications. This was because KelpDAO was using a single DVN (1/1) architecture at the time and did not implement the officially recommended redundant multi-DVN mechanism, resulting in a lack of independent validation nodes to identify forged messages. LayerZero stated that its protocol itself did not have vulnerabilities, applications with multi-DVN configurations were not affected, and there is no systemic risk. LayerZero announced that it will urge all projects using a single DVN configuration to migrate to a multi-DVN architecture as soon as possible. It has also suspended signature and verification services for 1/1 configuration applications. Additionally, the company is cooperating with global law enforcement agencies in the investigation and assisting industry partners in tracking the stolen funds. LayerZero stated that this incident highlights the value of modular security architecture and reminds the industry to pay attention to the potential security risks in RPC validation pathways.

ChainCatcher live report: Ethereum co-founder Vitalik Buterin delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. He defined Ethereum as having two core functions: first, as a public bulletin board for applications to publish messages and data; second, as shared digital objects controlled by code, covering assets, NFT, ENS, and DAO. He emphasized that Ethereum's goal is not to compete with high-frequency trading platforms in speed, but to become the most secure, most decentralized, and always online trusted chain. On the short-term roadmap, he introduced the account abstraction proposal EIP-8141, which can natively support smart contract wallets, quantum-resistant signature algorithms, and privacy protocols. Regarding quantum resistance, there are currently two signature schemes—hash-based and lattice-based—and the team is significantly improving their efficiency through EVM vectorization. He revealed that ZKVM is already fast enough to prove real-time EVM execution. The goal this year is to ensure its security, with plans to start deployment on a small portion of the network, and by 2028, make it the main method for verification chains, allowing Ethereum to scale significantly without sacrificing decentralization. Regarding the long-term vision, Ethereum is actively using AI-generated mathematical proofs to formally verify software security, and pursuing full quantum safety and maximum simplicity, ensuring platform security does not depend on the continuous existence of any single team.
