China’s Blockchain-based Service Network (BSN) has developed RealDID, a decentralized identity system that utilizes blockchain technology to verify the identities of its 1.4 billion citizens. This system allows users to register and log in to websites anonymously using Decentralized Identifiers (DIDs) and private keys, addressing concerns related to data privacy. The RealDID initiative aims to provide a more secure and private alternative for users, aligning with global trends in digital identity management. China’s blockchain innovations are causing geopolitical implications, with concerns about data access and privacy becoming central to the discourse. Meanwhile, IOTA’s Tangle technology distinguishes itself from traditional blockchains, making it an ideal candidate for China’s RealDID system. IOTA recently introduced Identity 1.0, a decentralized identifier mechanism that empowers users with full ownership and control of their digital identities. Additionally, IOTA’s Stardust protocol upgrade expands its capabilities beyond tokenization. With its expansion into the Middle East, Africa, and Asia, IOTA demonstrates a commitment to fostering a compliant and multifaceted blockchain ecosystem globally.
