UCAN-powered Multi-DID Integration Platform

Expert Rating

n/a

Overview

Abstracting over multiple identifier-schemes and identity systems requires a robust aggregation layer with sub-IDs, attentive to the different properties of (and deduplication or honesty guarantees lost between) multiple incompatible systems. We propose using IPFS for both generated and external documents and UCANs to power the Authorization thereof, making sub-IDs, verifiable credentials, and notarized public data all part of a cohesive hierarchical system.

The goal of this project is to conduct research on solutions and requirements for a decentralized digital identity (DDI) hub tailored to the needs of the SingularityNET ecosystem and its reputation system. This will include research into how existing DDI solutions can be integrated into a single hub that will allow for the creation of reputation scores that can be tied to unique verifiable identities while maintaining privacy. Part of the RFP is the definition of 2 or 3 RFPs for development of the envisioned system. This RFP is closely connected to the Reputation Platform RFP, and should be guiding the data privacy and identity integration solution of that RFP.

Milestone 1 - Validation of proposal

Description

Extensive research to validate: 1. each targeted use-case (some may be deferred if they cannot be adequately validated) 2. each considered sub-ID/DID-system and external data-source (including on-chain and KYC systems) 3. WaLT's feasibility to power aggregation of the above, including its ability to produce, verify, and track UCAN-based authorizations

Deliverables

Detailed report, with 5-10 pages for each included use-case, 1-2 for any deferred ones, 2-4 for each proposed sub-ID and data source, and 10 pages on WaLT and SNet/DeepFunding

Budget

$40,000 USD

Success Criterion

Confidence moving forward here is key, so clarity and readability are key in this document.

Milestone 2 - Prototyping and Iterating (with Reputation Team)

Description

Minimum-viable implementation of the DDI Aggregator-Hub, which can produce an end-to-end journey with dummy data for a few actors. Some steps may need to be postman and/or CLI. Aligning and coordinating with the design of the Reputation team will be critical here. Security, privacy, and KYC/legal-validity features will not be provided, but their implementability should be assessable from the prototype.

Deliverables

Running code with stubs and documentation for everything not yet implemented.

Budget

$55,000 USD

Success Criterion

Intelligibility to other teams and to milestone 3 are pivotal here, so taking good notes along the way is more important than the featureset at delivery.

Milestone 3 - Assessment and Future Work

Description

Lengthy report referring back to the earlier one to detail the fitness-for-purpose of each component and use-case applicability. May include RFPs for ongoing work to extend, replace, or iterate components prototyped in Milestone 2, ZK components, or KYC/legal outputs.

Deliverables

Same structure as Milestone 1 report, with additional sections for Reputation and ZK.

Budget

$25,000 USD

Success Criterion

Presenting this work at the Decentralized Identity Foundation and/or the Credentials Community Group of the W3C would trigger iterative/ongoing expert review and maximize the quality of submissions for future RFPs related to this project, so we would work backwards from this goal.
