IOTA Identity Alpha Release

Secure, Decentralized, and Scalable Digital Identity

TL;DR:
IOTA Identity is a decentralized identity framework that brings self-sovereign identity, verifiable credentials, and privacy-first digital interactions to the upcoming IOTA Mainnet. Now in Alpha Release, it migrates from the previous Stardust VM to the more powerful MoveVM, offering enhanced on-chain programmability while allowing privacy through off-chain verifiable credentials. Built on W3C’s DID standards, IOTA Identity delivers the best of both worlds: immutable, decentralized infrastructure paired with user-centric control over personal data.

In a digital world, data moves freely across borders, devices, and systems, forming the foundation of countless interactions. However, trust in digital data is difficult to maintain. Information can be manipulated or issued by unverified sources, threatening everything from e-commerce security to identity verification.

The problem centers on two key aspects: data integrity (ensuring information remains unaltered) and data authenticity (verifying the source of a claim). Without these guarantees, businesses, individuals, and machines struggle to establish trust, leading to inefficiencies, fraud, and security risks. Centralized identity systems attempt to address these issues but introduce gatekeepers, restrict user control, and increase vulnerability to single points of failure.

Solving the Trust Problem with Decentralization

To establish digital trust, two innovations enable verifiable, self-sovereign identities for secure digital interactions:

W3C Decentralized Identity Standards: The World Wide Web Consortium (W3C) has set a global, tech-agnostic standard for digital identity management, eliminating reliance on centralized databases. Decentralized Identifiers (DIDs) allow individuals, organizations, and devices to create, own, and control their digital identities, secured by cryptographic keys that ensure authenticity and prevent unauthorized changes.

Public Blockchain Infrastructure: A decentralized, tamper-proof ledger ensures the integrity of identity-related interactions. Public blockchains give users full control over their identities and assets by enabling self-sovereign ownership and verifiable attestations. Unlike centralized systems, a decentralized and permissionless ledger guarantees that identity proofs remain publicly auditable and resistant to censorship.

IOTA Identity: Redefining Digital Identity with Blockchain

The alpha release of IOTA Identity, now available on the MoveVM-based IOTA Testnet, marks a major step toward securing digital interactions with verifiable, tamper-proof identities. By combining W3C standards with the highly scalable, deterministic, and secure IOTA MoveVM, it provides a framework for authentication, verification, and secure data exchange.

IOTA Identity ensures data integrity on an immutable ledger while keeping verifiable credentials (VCs) off-chain for privacy and user control. Cryptographic verification ensures authenticity, while standardized formats enable seamless interoperability. Whether for personal credentials, business transactions, or IoT authentication, IOTA Identity fosters cross-platform trust with a user-centric model.

IOTA Identity delivers secure and verifiable interactions across multiple sectors:

Finance: KYC compliance, digital signatures, and fraud prevention.
Supply Chain: Verified product provenance and audit trails.
Healthcare: Secure patient records and privacy-preserving data sharing.
IoT & Smart Infrastructure: Device authentication and trusted machine-to-machine communication.
Governments & Enterprises: E-government services and corporate identity management.

By integrating self-sovereign identity (SSI) with a decentralized ledger, IOTA Identity offers a future-proof, scalable solution for verifiable digital interactions.

One Framework. Any Identity

The IOTA Identity framework serves as a universal layer of trust for the internet. Whether it's people, organizations, or things, the framework enables digital identities, fosters trust-building through verifiable credentials, and ensures seamless interaction among different entities.

Identity for People: IOTA Identity is based on Self-Sovereign Identity (SSI), ensuring privacy and autonomy by allowing users to manage their identities without relying on third parties. Instead of corporations storing and controlling personal information, individuals create verifiable, decentralized profiles, deciding what to share and with whom. This shifts power back to users, enhancing trust and security, reducing storage risks and supports GDPR compliance. And with verifiable credentials (VCs), users can authenticate themselves securely without exposing unnecessary personal details.

Identity for Organizations: Organizations often struggle with reputation issues due to data breaches. IOTA Identity enables verifiable credentials for Know-Your-Customer and Anti-Money Laundering processes, simplifying onboarding, cutting costs, and building trust. Decentralized identities also offer a fraud-resistant way to sign documents, removing reliance on centralized providers like Google.

Identity for Things: Sensor devices, cargo shipments, and industrial equipment are just some of the many things that benefit from secure digital identities. IOTA Identity enables Digital Twins, virtual counterparts of physical objects that store real-time data such as their authenticity, location, history, and condition. These verifiable identities enhance automation, monitoring, and efficiency across industries.

Core Identity Concepts

Decentralized Identifiers (DIDs) give individuals, businesses, and devices full ownership of their identities. Each DID is unique and can be used to securely verify identity across different digital interactions, ensuring greater privacy and security.

DID Documents link to DIDs and store critical identity-related data, including verification methods and authentication mechanisms. These documents allow users to prove ownership of their identity and selectively share information while maintaining control over their data.

Verifiable Credentials (VCs) function like digital passports, enabling users to prove specific attributes – such as age, qualifications, or certifications – without revealing unnecessary details. VCs operate off-chain, with only cryptographic proofs anchored on-chain, ensuring privacy, scalability, and user control while enabling secure, verifiable authentication.

Verifiable Presentations (VPs) enable selective disclosure by allowing holders to securely share one or more VCs in response to a verifier's request. Rather than exposing raw credentials, holders can present only the necessary proofs: For example, a job applicant can prove they hold a degree without revealing other personal details.

The Trust Triangle

As described above, IOTA Identity is based on Self-Sovereign Identity (SSI), which is built upon the trust triangle. This consists of three roles:

Identity Holders control their digital identities and personal data using DIDs.
Issuers (e.g., governments or universities) provide verifiable credentials to Identity Holders.
Verifiers request proof of specific claims, such as an employer verifying a job applicant’s degree.

The trust triangle ensures that trust is distributed rather than centralized. This decentralized model removes reliance on a single authority and enhances security, privacy, and user control over digital identities.
