- IOTA Identity 1.1 supports selective disclosure with SD-JWT, enhancing user privacy.
- Introduces StatusList2021, a scalable credential revocation scheme improving security.
In the rapidly evolving landscape of digital identity and blockchain technology, the recent release of IOTA Identity 1.1 marks a significant step forward for privacy and security online.
This latest iteration of the IOTA Identity framework introduces pivotal features that enhance user control and data integrity, notably through the addition of support for selective disclosure credentials in the Self-Describing JSON Web Token (SD-JWT) format and the implementation of StatusList2021, a well-defined and scalable revocation scheme.

Understanding IOTA Identity 1.1
IOTA Identity is a decentralized identity (DID) framework developed on the IOTA Tangle, a distributed ledger technology distinct from blockchain due to its directed acyclic graph (DAG) structure. This innovative approach enables fast, scalable, and feeless transactions, making it an ideal backbone for managing digital identities.
With the release of version 1.1, IOTA Identity not only solidifies its position in the DID space but also introduces features that directly address some of the most pressing issues in digital identity management today.
Selective Disclosure Credentials with SD-JWT
One of the headline features of IOTA Identity 1.1 is its support for selective disclosure credentials using the SD-JWT format. In the context of digital identities, selective disclosure allows individuals to share specific pieces of personal information without revealing their entire identity.
For instance, a user could prove their age to access age-restricted services without disclosing their full birth date or other personal details.
The adoption of SD-JWT as the format for these credentials is particularly noteworthy. JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims between two parties.
By enhancing JWTs with self-describing capabilities (SD-JWT), IOTA Identity 1.1 allows for credentials that are not only interoperable across different systems and services but also inherently more secure and privacy-preserving. This is because SD-JWTs can contain metadata describing how to verify them, making the verification process more transparent and reliable.
StatusList2021: A Scalable Revocation Scheme
Another critical advancement in IOTA Identity 1.1 is the introduction of StatusList2021, a revocation scheme that is both well-defined and scalable. Credential revocation is a necessary feature in any DID system, allowing issuers to invalidate credentials that are no longer accurate or have been compromised. However, traditional revocation mechanisms often struggle with scalability and privacy concerns.
StatusList2021 addresses these challenges by providing a method for managing the revocation of digital credentials that is efficient and preserves the privacy of the user. It does so by utilizing a list structure to represent the status of numerous credentials succinctly, enabling quick and easy checks to determine if a credential has been revoked.
This approach significantly reduces the overhead associated with managing and verifying the revocation status of credentials, making the system more scalable and user-friendly.
The enhancements brought by IOTA Identity 1.1 are poised to have a profound impact on the digital identity landscape. By empowering users with greater control over their personal information through selective disclosure and ensuring the integrity of digital credentials with a scalable revocation scheme, IOTA Identity 1.1 addresses two of the most significant challenges facing the DID ecosystem.
For developers and organizations, the upgrade offers new tools to build more secure, privacy-respecting services that cater to the growing demand for digital identity solutions. For users, it provides a more robust framework for managing their digital identities, enhancing their privacy and security online.
On the other hand, IOTA’s native token, IOTA, has shown a bullish price performance, with a 3.3% increase over the last 24 hours, reaching a price of $0.252, which also reflects a 4.55% increase over the past week.
