IoTeX launches the world's first on-chain identity solution ioID designed specifically for smart devices

ioID is revolutionizing the way identity is managed for smart devices, enabling decentralized IoT (DePIN) to authenticate devices, protect data, and unlock next-generation application scenarios within a user-owned, blockchain-agnostic ecosystem.

Recently, leading decentralized physical infrastructure ecosystem IoTeX officially announced the launch of the world’s first on-chain identity protocol for smart devices, ioID. With the explosive growth of smart devices in households, businesses, and cities worldwide, ioID addresses the urgent need for secure, verifiable, and programmable device identities, ushering in a new era of on-chain DePIN devices.

According to McKinsey’s forecast, by 2030, the number of smart devices will surpass the human population, with each person owning more than 10 smart devices and generating over 12 trillion USD in economic value annually. The intelligence of physical devices will drive them to become the foundation of the global economy, making their identity and data integrity crucial. ioID enables devices to achieve self-sovereignty, allowing them to sign and verify data on the device itself via smart contract wallets and private keys—a breakthrough in the DePIN sector.

How ioID is changing smart device identity:

• Device Sovereign Identity: Unlike traditional systems, ioID gives devices their own identity, enabling them to participate in on-chain activities like humans and to sign and verify real-world activities without relying on centralized intermediaries.
• Omnichain Compatibility: ioID is a unified solution applicable to any blockchain. Supported by omnichain compatibility technology, DePIN applications—whether energy networks, communication networks, or smart wearables—can operate compatibly on any chain.
• Tamper-Proof and Programmable: ioID is designed to resist tampering and features programmability, unlocking possibilities for device interoperability and innovation.

Since the testing phase at the beginning of 2024, ioID has been integrated with more than 10 DePIN projects, including GEODNET, Network3, Nubila, WatchX, and Envirobloq. As more projects and devices come onboard, IoTeX is able to refine ioID into a standardized, multifunctional solution that meets the diverse needs of DePIN developers globally. Through integration at the hardware, firmware, or software level, ioID makes device verifiability and interoperability accessible to all DePINs.

“ioID bridges the gap between the physical and digital worlds, providing devices with self-sovereign identity and making trust, verifiability, and programmability core features,” said IoTeX Co-founder and CEO Raullen. “This innovation changes the way devices interact with blockchains, empowering developers to unlock new application scenarios while building a secure and interoperable ecosystem.”

“ioID is not just an identity solution—it is the gateway for devices to participate in a decentralized future,” added IoTeX Co-founder and CTO Qevan. “By seamlessly integrating with the IoTeX 2.0 tech stack, ioID enables developers to create interoperable, scalable, and tamper-proof applications to address real-world challenges. This milestone reflects IoTeX’s commitment to building a more transparent and fair digital world, allowing devices and their data to serve their owners.”

The launch of ioID marks a significant milestone for IoTeX in connecting millions of real-world devices to the blockchain, enabling people to own and control their devices, data, and utility. As a key component of the IoTeX 2.0 tech stack, ioID seamlessly integrates with Decentralized Infrastructure Modules (DIMs), providing connectivity, storage, and computation between blockchain and the real world, unlocking new opportunities in the DePIN sector.
