Traditional blockchain technology poses challenges to implementing practical and sustainable decentralized identity solutions, such as scalability issues, high transaction fees, and energy consumption. However, Decentralized Identifiers (DIDs) with IOTA’s Tangle technology offer a promising solution to these challenges. This paper explores IOTA’s recent version Chrysalis, which provides a more energy-efficient and scalable infrastructure for implementing DIDs, particularly for heterogeneous IoT devices. The system enables these devices to create tamper-proof digital identities that are easily verified and used in various IoT applications. Additionally, the system is highly secure and cost-effective, with low transaction fees and minimal resource requirements. We discuss the current status of the work and provide a future vision for the IOTA-based DID system. This technology offers a more secure, efficient, and sustainable approach to decentralized identity management than traditional systems. The potential of IOTA’s DID system for IoT devices is significant, and we anticipate that it will lead to innovative use cases and solutions in the future.
