DID:STELLAR project will create a Stellar native self-sovereign decentralized and interoperable identity capability based on the W3C DID Core specification (https://www.w3.org/TR/did-core/).

Decentralized identity enables a trustless, portable, self-sovereign identity that removes reliance on centralized entities for authentication, authorization, user data and KYC/KYB.

Decentralized identity has a multitude of potential use cases, including on

Universal logins
KYC/KYB
Voting
Proof of human (sybil protection)
Lack of ID problems exploited by human trafficking and forced labour
Product provenance

DID is not a new concept, and virtually all leading blockchain platforms have implementations of the DID standard. An interoperable and portable decentralized identity implementation is one of the public goods that support effective decentralization in a privacy-preserving way while enabling interaction with advanced use cases that require some user authentication.

DIDs have seen adoption across end-user identity, organization identity and supply chain identity use cases. DID is an open an interoperable standard that is garnering adoption from both the public decentralized platforms as well as centralized entities (major financial institutions, multi-national oil and gas operators, U.S. government).

The DID:STELLAR project will implement the DID spec in general, similar to the way DID:ETHR project implements DID on the Ethereum Blockchain. More specifically, as part of this grant we will implement the following DID infrastructure:

A DID:STELLAR Method
DID method resolver
Management of the DID Document using the smart contract including Delegation, decoupling claims data from the underlying stellar address and support for existing stellar multisig capabilities.
Integration with the Universal DID Resolver

Changelog / Updates:

This proposal has been resubmitted as suggested with the following updates:

* Revised implementation effort for both DID Document, metadata attribute control and the open source js library implementation reducing overall project costs

* Wave costs of community awareness

* Added to the scope Integration with the Universal resolver to help bring traffic into Stellar

Overall resulting net cost of the project after revision and new scope went from 142K to 117K.

Deliverables

First Deliverable

As part of the first deliverable, DID:STELLAR Smart Contract, Mavennet will implement the DID Smart Contract on the Test Network. This Contract will enable resolution of a DID using existing stellar account identifiers to a DID Document.

We will rely on our experience implementing DID/VC functionality as well as deep understanding of the DID method specification to jump-start delivery and implement components right at the beginning of the project.

Reviewer instructions

The DID:STELLAR smart contract will be deployed on testnet with basic functionality including resolution to a DID Document. Any existing stellar account should be able to use this smart contract to resolve a did document that outlines its underlying public keys.
