At Spruce, we’re building the most secure and convenient way for developers to share authentic data. Here’s the latest from our open source development efforts:
Work-in-Progress: Creator Authenticity
We are currently working on a project that will enable creator authenticity for digital assets including NFTs. The initial smart contracts are written, as well as a CLI/library to interact with web applications. We plan on alpha testing the application this week.
Formally Verifying the Tezos DID Method
The Tezos DID method is a DID method that optimizes for privacy, enables formal verification, and scales to billions of identifiers by using “off-chain updates,” which allow private networks to extend and update on-chain data. A lot of our current work is focused on advancing did-tezos as the first formally verified DID Method.
We’ve continued work on improving the DID method’s core smart contract for on-chain updates. A first version of the formal proof has also been written, and a CI pipeline has been established.
DIDKit is a cross-platform toolkit for working with W3C Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs).
- Added a Python package.
- Added a Django example app.
- Added a Flask example app.
- Added a JavaServer Pages (JSP) example app.
- Added a Svelte example CHAPI wallet.
- We’ve enabled DID Methods to use HTTP(S) on WASM and Android.
- Conducted a test with the VC HTTP API v0.0.2 test suite. Test report.
- Worked on support for Relative DID URLs.
- Improved DID URL dereferencing to support more DID documents.
- Support publicKeyBase58 for Ed25519.
- Implement did:onion.
- (WIP) Implement did:pkh — a DID method for deterministic handling of public key hashes by curve.
- Released ssi v0.2.0.
- Published to crates.io: ssi, ssi-contexts, did-web, did-method-key, did-tz, did-sol, did-pkh, did-ethr, did-onion.
- General bug fixes.
Credible is a credential wallet for the verification, storage, and presentation of Verifiable Credentials using Decentralized Identifiers. In addition to our native mobile editions, we’ve since written a browser extension version of Credible along with an SDK to enhance any web application with decentralized identity.
