• IOTA has launched the latest version of its decentralized identity (DID) tool, IOTA Identity 1.0, incorporating the advancements from the Stardust protocol upgrade.
• The upgrade introduces Alias Outputs on Layer 1, enabling innovative interactions and expanding IOTA Identity’s capabilities.

IOTA, the innovative blockchain network, has officially introduced the latest version of its decentralized identity (DID) tool, IOTA Identity 1.0, following the successful integration of the Stardust protocol upgrade. The Stardust upgrade, initially introduced in September on the staging network, Shimmer, has undergone rigorous testing and refinement. Now, with its integration into the broader IOTA network, IOTA Identity 1.0 boasts enhanced capabilities.

Originally launched in 2018, IOTA Identity serves as a decentralized identity method, accompanied by a library. These components leverage the unique features of the IOTA ledger, enabling seamless integration of digital identities into both new and existing applications.

The latest iteration of IOTA Identity reflects a comprehensive technical revamp aligned with the Stardust version of the protocol. The process involves a complete rethinking of how identities are created, updated, and resolved. Alias Outputs, representing identities, now leverage the capabilities of the Stardust ledger, allowing interactions with other Layer 1 entities like fungible and non-fungible tokens (NFTs).

Technically, the storage of DID documents has been optimized by placing them in the state metadata field of Alias Outputs. This ensures accessibility for resolution across all nodes, utilizing Layer 1 access control mechanisms for ownership and permissions management. These enhancements mark a significant step forward in advancing IOTA’s decentralized identity capabilities and expanding its utility within the broader blockchain ecosystem.

Unlocking New Opportunities With IOTA Identity

In a groundbreaking move, the introduction of Alias Outputs on Layer 1 is set to transform interactions among entities, paving the way for innovative applications. This novel feature allows the control of one identity by another, establishing hierarchical structures for entities like company subsidiaries or human custodians.

The governing entity, referred to as the governor appoints a state controller to determine updates to an identity, shaping scenarios such as company relationships.

Crucially, Alias Outputs can currently have a single state controller, but plans for future protocol updates aim to enable multiple controllers, fostering increased flexibility and collaboration between entities. This advancement holds significant potential for identity management in diverse contexts.

Moreover, Alias Outputs prove instrumental in financial transactions, as they can hold tokens and convert any Decentralized Identifier (DID) into an address. This functionality ensures secure fund transfers, with the Alias Output serving as the unlock condition for basic outputs.

The Stardust protocol upgrade introduces a new dimension by facilitating the minting and transfer of Non-Fungible Tokens (NFTs) on Layer 1 through dedicated NFT Outputs. Entities like Phonemkr can leverage DIDs to authenticate the identity of NFT issuers, adding an extra layer of trust to digital interactions.

NFTs, unlockable and transferable to DIDs, offer a unique opportunity for ownership representation. This functionality extends beyond individuals to entities or organizations, allowing seamless transfer of ownership and corresponding identity in a single, efficient interaction. However, it is emphasized that such practices are not generally recommended for human identities.

The Stardust protocol upgrade marks a significant stride towards enhanced security, flexibility, and innovation on Layer 1, opening doors to a new era of decentralized interactions.
