> This is the official SDK for Hyperledger Indy, which provides a distributed-ledger-based foundation for self-sovereign identity. Indy provides a software ecosystem for private, secure, and powerful identity, and the Indy SDK enables clients for it. The major artifact of the SDK is a C-callable library; there are also convenience wrappers for various programming languages and Indy CLI tool.

> You can store your identities in a location where you can edit or delete them. After giving the location of your identities, the Indy platform lists your location with a globally identifiable name. When someone wants to read your identity data, the Indy platform points out the location of your identities. Let’s look into the details of how it works.

> Indy is all about giving identity owners independent control of their personal data and relationships. Indy is built so that the owner of the identity is structurally part of transactions made about that identity. Pairwise identifiers not only prevent correlation, but they stop third parties from transacting without the identity owner taking part since the identity owner is the only place pairwise identifiers can be correlated.

> To manage patient’s self-sovereign identity, we leveraged the Hyperledger Indy blockchain framework to store patient’s decentralized identifiers (DIDs) and the schemas or format for each credential type. In contrast, the credentials containing patient data are stored “off-ledger” in each person’s wallet and accessible via a computer or smartphone. We used Hyperledger Aries as a middleware layer (API) to connect Hyperledger Indy with the front-end, which was developed using a JavaScript framework, ReactJS (Web Application) and React Native (iOS Application).

* [Welcome Hyperledger Ursa!](https://www.hyperledger.org/blog/2018/12/04/welcome-hyperledger-ursa)
> Ursa aims to include things like a comprehensive library of modular signatures and symmetric-key primitives built on top of existing implementations, so blockchain developers can choose and modify their cryptographic schemes with a simple configuration file change. Ursa will also have implementations of newer, fancier cryptography, including things like pairing-based signatures, threshold signatures, and aggregate signatures, and also zero-knowledge primitives like SNARKs.
* [Sovrin contributes to Hyperledger Ursa: A win for cryptography, security, and interoperability](https://sovrin.org/sovrin-contributes-to-hyperledger-ursa-a-win-for-cryptography-security-and-interoperability/)
> Ursa is a library for cryptography and the result of a collaborative effort from teams at ACM, Bitwise, DFINITY, Evernym, Fujitsu, Intel, the Linux Foundation, the Sovrin Foundation, and State Street. Duplication among blockchain project features heightens security risks. Ursa, however, gathers up crypto implementations across projects and compiles them into a single metalibrary, creating a central repository for crypto code. This way, projects can select sources of code from Ursa, instead of the original source, decreasing duplication security risks and boosting interoperability among projects.

> Kiva Protocol is built using Hyperledger Indy, Aries, and Ursa, and as implemented in Sierra Leone, allows citizens to perform electronic Know Your Customer (eKYC) verifications in about 11 seconds, using just their national ID number and a fingerprint. With this verification, it is possible for the nation’s unbanked to open a savings account and move into the formally banked population.

## Sovrin Stewards
## [Sovrin Stewards](https://sovrin.org/stewards/)
The Sovrin ledger is operated by Stewards, trusted organizations within the ecosystem who have agreed to abide by the requirements in the [Sovrin Trust Framework](https://sovrin.org/library/sovrin-governance-framework/) and are responsible for operation the nodes that maintain the Sovrin distributed ledger.
Stewards also, as a group, accept or reject any changes to the ledger-specific portions of the Sovrin open source code by virtue of that role. They thus provide a counterbalance to the Sovrin architects who maintain the Indy code base.

> Much more can be done. For example, in the identity area, the Fabric team has developed an attribute-based identity verification mechanism called Identity Mixer that uses zero-knowledge proofs to demonstrate possession of digital signatures and private keys. Using this technology, Mixer allows you to prove you can do something without revealing who you are. On the other hand, if the goal is identity masking without attribute claims, the Ethereum community has been using a much simpler technique called Hierarchical Deterministic Wallet (HD-Wallet), which originated in the Bitcoin community so that you never reuse a digital identifier more than once. This eliminates any ability to correlate transactions over time, while all private keys are derived from a single root secret.\
> [...]\
> On the identity front, ideally the identities of an organization would not need to be re-built from scratch each time it joins a new consortium. Using a common decentralized identity system, whether it’s based on Hyperledger Indy or Ethereum uPort, or even based on links to legacy federated SSO systems such as ActiveDirectory or LDAP, makes this possible. Certainly more work is required to make this a reality.

> To understand why DLT is useful for identity, we need to go back to the basics—paper credentials, how that model has worked for 1000s of years, and how the use of DLTs with verifiable credentials allows us to transition the great parts—security and privacy—of that model to the digital age.

A few open-source libraries exist to sidestep this infrastructural lock-in, but these are more like primitives for assembling an SSI toolkit than ready-to-go, developer-friendly libraries. DIDKit, on the other hand, is ready to start processing real-world VCs with non-repudiable signatures right out the box.

IDunion is also a [project](https://www.digitale-technologien.de/DT/Redaktion/DE/Standardartikel/SchaufensterSichereDigIdentProjekte/Schaufensterprojekte/sdi-projekt_idunion.html) co-funded by the [German Federal Ministry of Economic Affairs (BMWi)](https://www.bmwi.de/Navigation/EN/Home/home.html) as part of the [Showcases Secure Digital Identities program](https://www.digitale-technologien.de/DT/Navigation/DE/ProgrammeProjekte/AktuelleTechnologieprogramme/Sichere_Digitale_Identitaeten/sichere_digitale_ident.html). We gave an introduction covering
- The IDunion consortium consists of 37 partners - other major partners have already signaled interest in participating
- Our solution is enabled by the distributed ledger technology (DLT) and the concept of self-sovereign identities (SSI)
- Instead of a central authority, trust is organized via a DLT network, which works as a decentralized PKI system
- In recent months, in addition to intensive research, we have developed a DLT test network including governance structure, 35+ use cases and numerous software components for the allocation, verification and management of digital identity data developed
- In the future, the identity network will be managed by a European cooperative in which every institution in the EU can participate
- In total, we are working on 35 use cases in the areas of eGovernment, education, finance, industry/IOT, eCommerce/mobility, IAM, and eHealth

Practical session, what we are actually building today using the hyper ledger Aries tools
Some interesting points
- Viewing organizations as Issuers, Verifiers and Holders
- Talked about the complexity of defining a verifiable credential, I.e. what are you attesting to?
- Went over the need to make it easier for users to be able to create credential schemas and credential definitions without having to gain understanding about the tech.
- Question was asked about where do we start, do we have to bootstrap the first credential? And we went over being able to start with existing governance structures, and the trust that is already accepted there to issue the first credentials.
- I gave a demo of our prototype that shows three actors (Mine, Bank, Verifier) doing a credential exchange flow between them

> As our approach evolves, we also remain keen to support open source solutions that interoperate with other national and international efforts. There is no dominant design yet, no one network or technology, so we must remain nimble and flexible in our exploration. We also need to coexist with existing identity solutions that millions of British Columbians already rely upon.

Business partner agent, credential management, issuers, verifiers, holders, digital wallet
Practical session, what we are actually building today using the hyper ledger Aries tools
Some interesting points
- Viewing organizations as Issuers, Verifiers and Holders
- Talked about the complexity of defining a verifiable credential, I.e. what are you attesting to?
- Went over the need to make it easier for users to be able to create credential schemas and credential definitions without having to gain understanding about the tech.
- Question was asked about where do we start, do we have to bootstrap the first credential? And we went over being able to start with existing governance structures, and the trust that is already accepted there to issue the first credentials.
- I gave a demo of our prototype that shows three actors (Mine, Bank, Verifier) doing a credential exchange flow between them

> - The Indicio MainNet is an enterprise-grade ledger for use by decentralized identity applications.
> - We brought up the node using AWS Elastic Cloud Computing (EC2) instances within a Virtual Private Cloud (VPC).
> - We pulled the validator algorithms from the open-source project, [Hyperledger Indy](https://www.hyperledger.org/use/hyperledger-indy).
> - A supporting machine operates the command line interface used to perform steward operations onthe ledger.
> - We used security groups at the network interface level to create a firewall.
> - We set up monitoring in AWS CloudWatch using a variety of bash scripting in conjunction with Ubuntu and AWS provided utilities.
> - We created a regular maintenance schedule.

> To manage patient’s self-sovereign identity, we leveraged the Hyperledger Indy blockchain framework to store patient’s decentralized identifiers (DIDs) and the schemas or format for each credential type. In contrast, the credentials containing patient data are stored “off-ledger” in each person’s wallet and accessible via a computer or smartphone. We used Hyperledger Aries as a middleware layer (API) to connect Hyperledger Indy with the front-end, which was developed using a JavaScript framework, ReactJS (Web Application) and React Native (iOS Application).

## Schema
* [Announcing Schema Markup Validator: validator.schema.org (beta)](http://blog.schema.org/2021/05/announcing-schema-markup-validator.html)
SDTT is a tool from Google which began life as the [Rich Snippets Testing Tool](https://developers.google.com/search/blog/2010/09/rich-snippets-testing-tool-improvements) back in 2010. Last year Google [announced plans](https://developers.google.com/search/blog/2020/07/rich-results-test-out-of-beta) to migrate from SDTT to successor tooling, the [Rich Results Test](https://search.google.com/test/rich-results), alongside plans to "deprecate the Structured Data Testing Tool". The newer Google tooling is focused on helping publishers who are targeting specific schema.org-powered [search features](https://developers.google.com/search/docs/guides/search-gallery) offered by Google, and for these purposes is a huge improvement as it contextualizes many warnings and errors to a specific target application.
## Semantics
* [The Importance of Data Inputs and Semantics for SSI with Paul Knowles [Podcast]](https://northernblock.io/semantics-for-ssi-with-paul-knowles/)
> The platform was an incredibly federated platform when I built it because I didn’t know that SSI existed. So as soon as I found that ecosystem, I tore up the rulebook and said, “This isn’t going to work; I have to rebuild it.”
## QR
* [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.
## Mobile Agent Dev
* [App Framework for Mobile Agent Dev - “No more forking”](https://iiw.idcommons.net/22A/_App_Framework_for_Mobile_Agent_Dev_-_%22No_more_forking%22) by Horacio Nunez
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:

Digital Caribou shares their thoughts on [Digital Transformation and inclusion](https://medium.com/caribou-digital/transformation-in-a-digital-age-9068338fd778) - very good thinking for all of us working on digital identity.
> We believe that the emphasis on transformation as both process and effects is particularly important, especially as although digitization and digitalization are well underway, accelerated by the response to COVID-19 (remote working, payments, etc.), these are not inevitable processes. They are the results of human decisions. Similarly, the effects of these are not inevitable, either.
