Data: The cryptocurrency sector generally retraced, with the Layer 2 sector leading the decline by nearly 9%, and BTC briefly fell below $105,000

ChainCatcher message indicates that, according to SoSoValue data, the crypto sector is generally experiencing a pullback, with the Layer2 sector down 8.70% in the last 24 hours. Within the sector, Arbitrum (ARB), Optimism (OP), and Starknet (STRK) fell by 11.31%, 11.43%, and 12.94% respectively. Bitcoin (BTC) dropped 2.31%, briefly falling below the $105,000 mark. Ethereum (ETH) also faced a pullback, decreasing by 4.21% and dropping below $2,600.In other sectors, the CeFi sector declined by 2.98%, with Hyperliquid (HYPE) continuing its downward trend, falling another 4.85% in 24 hours, while LEO Token (LEO) remained relatively strong, rising by 1.18%; the PayFi sector decreased by 4.34%, but Safe (SAFE) rose against the trend by 22.09%; the Layer1 sector fell by 4.83%, with TRON (TRX) and Binance Coin (BNB) finding support, decreasing by 0.51% and 2.40% respectively; the DeFi sector dropped by 7.24%, with Uniswap (UNI), which had previously seen significant gains, falling by 10.78%, and the Meme sector decreased by 8.21%, with Pepe (PEPE) and Fartcoin (FARTCOIN) dropping by 8.01% and 9.40% respectively, but SPX6900 (SPX) rose for two consecutive days, peaking at 4.46% during the session.The crypto sector indices reflecting historical market performance show that the ssiLayer2, ssiAI, and ssiDePIN indices fell by 9.05%, 8.59%, and 8.49% respectively in the last 24 hours.

Mind Network announces the integration of Circle CCTP and the launch of an encrypted transmission layer to achieve native USDC cross-chain transfer

ChainCatcher news, according to the official announcement, MindNetwork has officially integrated Circle's CCTP cross-chain protocol. By combining its FHE (Fully Homomorphic Encryption) cross-chain bridge with Chainlink's CCIP cross-chain interoperability protocol, it enables compliant privacy-protected native USDC cross-chain transfers.As the first introduction of FHE technology in CCTP, developers can achieve address and specific transaction privacy encryption on chains such as Ethereum, Arbitrum, and Polygon without changing Circle's infrastructure or existing deployments, thus providing new use cases for fields like DeFi and RWA.This feature is primarily suitable for institutional-level scenarios such as asset management, institutional settlement, and cross-chain fund scheduling, while also supporting the generation of ZK zero-knowledge proofs to meet compliance and auditing needs. An SDK has been opened, allowing developers to seamlessly integrate it into wallets, dApps, or cross-chain bridge applications for plug-and-play functionality.Mind Network is pioneering a Fully Homomorphic Encryption (FHE) infrastructure resistant to quantum attacks, driving a fully encrypted internet through secure data and AI computation. Collaborating with industry leaders, it promotes the development of the zero-trust internet protocol HTTPZ, setting new standards for trusted AI and encrypted data processing in the Web3 and AI ecosystems.

Ethereum developers activate the Pectra upgrade, which includes 11 improvements such as enhanced staking efficiency and improved Layer 2 scalability

ChainCatcher news, according to The Block, the Ethereum mainnet successfully activated the Pectra upgrade at 6:05 AM Eastern Time, marking the most significant network update since the Merge in 2022.This hard fork includes 11 EIP improvement proposals, primarily focusing on three major areas: enhancing staking efficiency, optimizing user experience, and improving Layer2 scalability. The successful deployment of the testnet Hoodi in March laid the foundation for this upgrade. Pectra sets the stage for the Fusaka upgrade, which will introduce key technologies such as Verkle Trees and PeerDAS.Among the highlights of this upgrade is the EIP-7702 account abstraction scheme, which allows regular wallets to temporarily execute smart contract functions. In the future, users will be able to experience innovative features such as third-party payment of Gas fees, batch transaction packaging, and even recovery of lost private keys through social contacts. In terms of the staking mechanism, the ETH staking limit for a single validator node has been significantly increased from 32 to 2048, allowing institutional stakers to reduce operational complexity through node merging.For Layer2 scalability, the Blob data capacity per block has doubled to 6 (peaking at 9), and the proto-danksharding technology based on last year's Dencun upgrade continues to deepen, which is expected to reduce transaction costs on Rollup chains like Arbitrum by over 90%. The technical team has also addressed several long-standing pain points: the activation time for validator nodes has been reduced from 12 hours to 13 minutes, the execution layer can directly control node exits to enhance key security, and the on-chain storage of historical block hash data has improved the reliability of decentralized oracles.
