This week, we’re proud to announce the v0.2.1 release of DIDKit on Cargo, and DIDKit-WASM v0.1.7 on npm.
DIDKit is a cross-platform toolkit for working with W3C Verifiable Credentials and Decentralized Identifiers. It has SDKs in JavaScript, Java, Python, and more, and it even runs in the browser frontend. It supports a variety of cryptographic algorithms allowing it to seamlessly bridge trust across different blockchains and public key infrastructures, including traditional X.509 and TLS.
We wrote DIDKit in Rust due to its memory safety, expressive type system, and suitability across a variety of systems and environments. For example, the Rust…
We’re excited to announce the alpha launch of Tezos Profiles (TZP), which can be found at tzprofiles.com.
TZP is a web application that helps users regain control of their digital identity for use across platforms, and enables the creation of portable verified profiles by demonstrating control over public social media accounts and by self-attesting information. These verified profiles are then linked to Tezos accounts, allowing any platform to resolve and establish trusted information to mitigate identity fraud.
We encourage users to start creating and launching their profiles as we begin integrating Tezos Profiles support across the Tezos ecosystem. Currently, we…
At Spruce, we’re building the most secure and convenient way for developers to share authentic data. Here’s the latest from our development efforts:
Tezos Profiles & Kepler
Tezos Profiles (TZP) is an in-development web application that helps users regain control of their digital identity for use across platforms. It allows users to create portable verified profiles by demonstrating control over their public social media accounts, and by associating self-attested basic profile information. These verified profiles are then linked to Tezos accounts, allowing any platform to resolve and establish trusted information to mitigate identity fraud.
Tezos Profiles uses Kepler. Kepler provides an IPFS-like storage system…

Loss of Trust, Loss of Connection
With the accelerated growth of NFT adoption, creator impersonation and copyminting have unfortunately become widespread, with many buyers unsure if an NFT is being…

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
At Spruce, we’re building a product suite to manage all aspects of the data supply chain. Here’s the latest from our development efforts:
The Tezos DID Method
A DID Method geared for privacy, formal verification, and scaling to billions of identifiers by using off-chain updates.
Spruce and TQ Tezos are jointly releasing the draft specification and initial implementation of Decentralized Identifiers (DIDs) based on the Tezos blockchain. We began our collaboration with TQ Tezos and the wider Tezos ecosystem in August to take full advantage of Tezos’ production-tested proof-of-stake consensus mechanism, ability to perform protocol upgrades, and toolsets for formal methods.
We welcome review of our Tezos DID Method specification, TZIP-019 companion specification, and open-source implementation based on DIDKit. …
Credible v0.1 pushed to GitHub with its core functionality enabled, documentation, and is moving towards stability for white-labeling.
Today, Spruce is open-sourcing under the Apache 2.0 license an early developer release of Credible (GitHub repository here), a native mobile wallet for W3C Verifiable Credentials and Decentralized Identifiers built on DIDKit and Flutter. We were able to package the DIDKit library written in Rust into a Flutter application running on both Android and iOS, using C bindings and Dart’s FFI capabilities. …

DIDKit v0.1 pushed to GitHub with its core features, documentation, and interfaces intact.
DIDKit is a lightweight set of Rust libraries containing a command-line interface and an HTTP interface. Both interfaces expose the core Verifiable Credential-handling capabilities of Spruce’s ssi library. Both ssi and didkit are being open-sourced this week to allow “early access” to the core source code, for review and consideration in advance of a substantial third-party audit.
But what exactly are “VC capabilities,” or for that matter, “DID capabilities”? Why is it so hard to find pluggable libraries that bring them to your project?
