ChainCatcher message, Blockfence has issued a reminder that due to a security vulnerability being frequently exploited, Apple has released emergency updates for macOS, iOS, iPadOS, tvOS, and watchOS. Please update to the following versions as soon as possible: iOS 17.2.1, iPadOS 17.2, macOS 14.2.1, tvOS 17.2, watchOS 10.2.

ChainCatcher news, according to official sources, the cryptographic technology provider PADO Labs completed a $3 million seed round financing six months ago and announced that its Beta version product is about to launch for internal testing.It is reported that PADO will utilize cryptographic algorithms, through technologies such as Interactive Zero-Knowledge Proofs (IZK) and Secure Multi-Party Computation (MPC), to be the first to integrate off-chain data into the on-chain world. This ensures compliant, secure, private, and verifiable links, facilitating the creation of interconnected and composable user credit credentials. PADO's vision is to establish a fully decentralized credit protocol centered around users.

ChianCatcher news, according to an official tweet, the distributed credit protocol PADO has partnered with ZAN to provide users with a user-friendly, privacy-protecting lightweight eKYC service based on POV (Proof of Verification). Once users complete an eKYC certification, they can flexibly choose how to use the certification results through ZK credential verification. The certification results of POV can also be combined with PADO's services to provide users with RWA (Real World Asset) proof, offering richer real credit credentials for the Web3 community. This service has supported on-chain proof service frameworks for EAS and Polygon ID.It is reported that PADO is a service provider of cryptographic algorithm technology, aiming to build a reliable and secure distributed credit protocol. By using MPC-TLS technology to verify the authenticity of user access data while protecting user privacy, it combines IZK to provide users with various on-chain data proofs.ZAN, supported by AntChain OpenLab, is dedicated to protecting and optimizing Web3 applications, platforms, and businesses. ZAN provides a comprehensive range of technologies, products, and solutions for the Web3 ecosystem, including smart contract auditing (SCR), KYT (Know Your Transaction), KYC, node services, POV (privacy-preserving oriented identity authentication), and other customized services.
