  > A JWT is a structured security token format used to encode JSON data. The main reason to use JWT is to exchange JSON data in a way that can be cryptographically verified. There are two types of JWTs:
> - JSON Web Signature (JWS)
> - JSON Web Encryption (JWE)
> The data in a JWS is public—meaning anyone with the token can read the data—whereas a JWE is encrypted and private. To read data contained within a JWE, you need both the token and a secret key.

  > rLogin allows web application developers to integrate blockchain technologies giving the user the power of data portability. After integrating rLogin you achieve:

- A back-end authenticating users by their wallet addressed - their Decentralized Identifiers.
- A registration model capable of requesting users for data stored in its user-centric cloud storage, the Data Vault.
- A front-end capable of interacting with any wallet that the user chooses, with a pre-designed user experience for registration and login.
- Compatibility with a unified platform where the user can control their identity and information, the RIF Identity Manager.

This article shows how use verifiable credentials stored on a digital wallet to verify a digital identity and use in an application. For this to work, a trust needs to exist between the verifiable credential issuer and the application which requires the verifiable credentials to verify. A blockchain decentralized database is used and MATTR is used as a access layer to this ledger and blockchain. The applications are implemented in ASP.NET Core.
* [Gordian QR Tool Supports Vaccine Records, 2FAs, Cryptoseeds, and More](https://www.blockchaincommons.com/projects/Releasing-QRTool/) Blockchain Commons
  > Some possible architectural issues arise from using QR codes for confidential data, such as the fact that you’re actually transmitting the data (not a proof of the data), that the QRs tend to contain all of the data (not just a selection), and that there’s no way to rescind a QR or expire it. Those issues will have to be dealt with at a foundational level as we figure out what can safely be encoded as a QR — and more importantly how to offer restricted proofs rather than complete information.
* [Build an SSI proof of concept in <30 minutes](https://iiw.idcommons.net/21G/_Build_an_SSI_proof_of_concept_in_30_minutes) by Riley Hughes

The session began with a short introduction to SSI, an introduction to Trinsic, and an overview of how to get started. Then, everybody present starting building an SSI proof of concept, creating issuers, verifiers, and schemas to learn first-hand how it all works.

This session had the objective to present a solution to the problem of forking when developing new mobile agents. With the current starting kits available in the community it is very easy to start a path where it is almost impossible to retrofit updates to the kit back into our custom agent.

The solution consists in using a framework-first approach and ensuring that custom code can reside exclusively outside of the framework, thus ensuring updates can be executed more easily.

The following link can be used as the public url for the project:

Once deployed in a future version of the protocol, it will allow Ceramic to be fully compatible with the new Sign-in with Ethereum (SIWE) specification as well as provide advanced data flow control features for resources stored on the Ceramic network.

- The [Tezos DID Method](https://did-tezos-draft.spruceid.com/) specifies how Tezos can be used for DID creation and management, compatible with the issuance, storage, and verification of Verifiable Credentials.
- [DIDKit](https://sprucesystems.medium.com/introducing-didkit-an-identity-toolkit-e0dfa292f53d) is a cross-platform toolkit for working with W3C Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs).
- [Credible](https://medium.com/@sprucesystems/spruce-developer-update-2-484368f87ee9) is Spruce’s native credential wallet for the consumption, storage, and presentation of Verifiable Credentials on Android and iOS.
- Keylink is Spruce’s tool to link existing enterprise accounts to keypairs.
- Intake is a smarter onboarding tool for businesses via secure document collection and processing. These artifacts can then be used as evidence to generate and issue credentials to the counterparty that originally uploaded them.

Inspiration - for folks engaging with new code

As a frequent open source maintainer and contributor, I’m often asked: where do you start? How do you approach a new project with the goal of making meaningful changes? How can you possibly understand the internals of a complex project?

At the most superficial level, we know that the expectations of board members drive decisions.  The decisions we take link to incentives, rewards and motivations and our shared values.

* [Are Transactional Relationships Enough?](https://www.windley.com/archives/2022/03/are_transactional_relationships_enough.shtml) Phil WIndley

Our online relationships are almost all transactional. A purely transaction digital life can't feel as rich and satisfying as one based on interactional relationships. As more of our relationships are intermediated by technology, finding ways to support interactional relationships will allow us to live authentic digital lives.

* [Verifiable Actions for signing and verifying VCs with DIDs](https://medium.com/@Transmute/verifiable-actions-for-signing-and-verifying-vcs-with-dids-a4176fb5ba3f) Transmute

Building better, more human-centric solutions in smart cities starts by realising that citizens and their digital footprints are not merely aspects to monitor and evaluate. They are active participants in the cities we live and work together and need to be engaged in designing better cities and managing the data about themselves. This is not important only for respecting citizens’ rights, but it is crucial to building sustainable services and humane cities.

we want to explain what we talk about when we talk about Open Recognition. It builds on this [previous post](https://blog.weareopen.coop/what-is-open-recognition-anyway-9f38ec1f8629), and aims to move from the abstract to practicalities.

this article describes a simple approach to revoke verifiable credentials and a decentralized and efficient way to index and query those revoked credentials using the [Graph protocol](https://thegraph.com/en/).

We consider the knowledge of Self-Sovereign Identity (SSI) and rudimentary knowledge of the [Ethr DID method](https://github.com/decentralized-identity/ethr-did-resolver/blob/master/doc/did-method-spec.md) as a requirement for understanding this article.

TL;DR: chapi.io is a site that helps developers integrate Verifiable Credential issuance, holding, and presentation into their applications. It includes a playground that can issue arbitrary VCs to digital wallets (web and native). It also includes tutorials on how Web Developers can add CHAPI integration to their websites. All you need to try it out is a web browser.

Summary: Building a better internet won't happen by chance or simply maximizing freedom. We have to build systems that support justice. How can we do that? Philosophy discussions are the black hole of identity. Once you get in, you can't get out. Nevertheless, I find that I'm drawn to them
