DidRoom

DidRoom is an open-source multiplatform and multifunctional Identity DID/SSI wallet, compliant with the W3C-DID and W3C-VC standards and with the current “The European Digital Identity Wallet Architecture and Reference Framework” (EUDI – ARF, version 1.0.0 from January 2023) which is the technical core of the eIDAS 2.0 regulation. DidRoom will also have advanced cryptographic and blockchain functions, including signatures, multi-signatures and blockchain interoperability (for Ethereum, Hyperledger Fabric and Sawtooth, and Planetmint)

DidRoom is based on a stack of open-source components and middlewares implemented by the Dyne.org Foundation during several H2020 and EC-funded research projects. The relevant components of the Zenroom ecosystem are:

  • The cryptographic virtual machine “Zenroom”: a multi-platform virtual machine for
    cryptography (signatures, hashes, multisignature, zero knowledge proof, quantum proof cryptography) blockchain interoperability (Ethereum, Hyperledger Fabric and Sawtooth, Bitcoin, Planetmint), that supports W3C-DID and W3C.VC natively – https://zenroom.org/
  • Dyne.org’s W3C-DID implementation: a federated 4-levels W3C-DID method, supporting multiple storage mechanisms (filesystem, databases, blockchains, Git, IPFS) with a builtin explorer. Intro: https://forkbomb.eu/products/w3c-did/ repo:

  • Zenswarm: blockchain oracle technology built for blockchain interoperability and offchain cryptography, with a built-in off-chain consensus algorithm, using Zenroom at its core and developed within the EBSI PCP, intro: https://forkbomb.eu/products/zenswarmrepo: https://github.com/dyne/zenswarm
  • Signroom: Open source, modular, easy to extend, web-based service, leveraging Zenroom’s cryptographic capabilities, allowing users sign documents and objects, using W3C-DID identities.

  • Motivation for the project: Didroom is component of the Zenroom ecosystem, based on the award winning Zenroom virtual machine. Zenroom offers unprecedented cryptographic and blockhain interoperability capabilities, which will be translated in features for identity/SSI solution via the Didroom wallet. Didroom is entirely open source, and built with modularity and expandability in mind, making it a very solid based for a third party to implement e feature-rich solution.
  • Generic use case description: We have a first generic use-case, where users create DIDs, and can receive credentials of different kinds from issuers, created by the platform. Users can also sign different data objects and get signatures verified. We have also collaboration with different partners for specific use cases, which will be announced shortly.
  • Essential functionalities: The creation of DIDs ; The creation of credential issuers; Issuing credentials (W3C-VC, Coconut, BBS); Verifying credentials; Signatures of data using different signature algorithms; Verifications of credentials and signatures via a blockchain oracle; Perform different operations on blockchain.
  • How these functionalities can be integrated within the software ecosystem: Through different strategies: 1. Integrating the Didroom front-end or back-end into existing solutions 2. Integrating Zenroom into existing solutions; 3. Using the Zenswarm Oracle for various cryptographic functions.
  • Gap being addressed: Every other wallet in the world is based on 3rd party libraries, which are typically blockchain or feature specific, and written for a specific platform or software toolchain. Didroom can perform very advance cryptography and blockchain interoperability, using our own Zenroom virtual machine: this is a unique technological advantage, allowing to expand the wallet capabilities to an unprecedented level.
  • Expected benefits achieved with the novel technology building blocks: Extended cryptographic capabilities Extended blockchain interoperability Superior ease of integration and interoperability thanks to the Zenswarm Oracle capabilities
  • Potential demonstration scenario: For example, a user can:
    - Create a DID, scan a QR code and received a W3C-VC;
    - Sign an object or a document, verify signatures;
    - Use/spend a credential, like a W3C-VC or a zero-knowledge proof;
    - Start a multisignature process using BLS-based homomorphic multisignature;
    - Execute smart-contracts on blockchainStore data in db, Redis, IPFS

    An issuer can:
    - Create several credential issuers with different capabilities;
    - Invite users to receive credentials;
    - Verify credentials;
    - Control the DIDs of issuers of lower hierarchical level.
