Hyperledger
DIDs Fabric and Decentralized Networking
-
DEON is a new Hyperledger project focused in off-line communication networks, independent of internet infrastructure. This could be used to enable networks of devices to communicate peer-to-peer (without the need to ‘phone home’ over the internet), inter-enterprise consortia networks, and enabling user-centric data sharing in a more secure and private fashion. 2020-11-05

Add support for "did:indy" to Hyperledger Indy Node and Indy VDR </>Code With Us
Accpting Applications until 1/10 4:00 PM PST
The total funding for the challenge is $70,000CDN and is divided into 4 phases. The first 3 phases require the use of Python working on the Indy Node.

The current credential verification process relies on transaction processing by a ledger with transaction processing bottlenecks, which may constrain the ideal of non-repudiation.

First we’re going to create a holder Agent, this will be the Agent that receives the membership credential. During their life, the holder will collect many different verifiable credentials. Memberships, ID-cards, even purchasing records.

In this video, we will demonstrate how to create new Verifiable Credentials with custom schemas using the NB Orbit enterprise app. Once the credential schema is created and the attribute fields specified, the enterprise user can then publish a credential definition to whatever root of trust they are using, in our case a Hyperledger Indy network.

Declaring that blockchain has “gone mainstream,” Forbes today released its 2021 “Blockchain 50,” featuring companies that have at least $1 billion in revenues or are valued at $1 billion or more and “lead in employing distributed ledger technology.” And, once again, half of the companies on the list are using Hyperledger technology.* Why Distributed Ledger Technology (DLT) for Identity? Hyperledger 2021-04-21 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.

There was some discussion about the way to present such a profile, especially the way it is currently implemented as an endpoint in the did document pointing to a https ressource (json-ld document served using normal https).
One alternative, to create a DIDcomm-based protocol for public profile was discussed and would be a good alternative at the cost of every client having to be able to speak DIDcomm.
- Investing in Verifiable Credentials, Technical Interoperability and Open Source Hyperledger 2022-08-23
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.

IDunion Introduction and AMA (there will be another one tomorrow!) by Andre Kudra + available IDunion crew!
-
IDunion enables self-determined identities based on Self-Sovereign Identity (SSI) technologies Hyperledger Indy and Hyperledger Aries. The aim of the IDunion organisation is to create an open ecosystem for decentralised identity management, which can be used worldwide and is based on European values and regulations. IDunion is also a project co-funded by the German Federal Ministry of Economic Affairs (BMWi) as part of the Showcases Secure Digital Identities program. 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

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

IdRamp presented with Oracle at Hyperledger Global Forum June 2021. The event focused on enterprise use of blockchain technologies using the 15 projects that fall under the Hyperledger “greenhouse”. Keynotes and speakers shared their insights on the current state of enterprise blockchain adoption across several hot topics including central bank digital currencies (CBDCs), non fungible tokens (NFTs), and most importantly– identity.
Here, we go through how we went about standing up our Indico node. In brief:
- 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.
- 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.
- Getting Internet Identity Right 30 Years On Money ReImagined with Brian Behlendorf.
Michael Casey and Sheila Warren talk to Hyperledger Executive Director Brian Behlendorf about self-sovereign identity, the topic of this week's column. A developer whose three-decade career has seen him deeply involved in efforts to foster a more open internet, Brian grasps, like few others, the nuances of how human beings should live within a rapidly changing digital economy.
- Hyperledger completes development of DID:Indy Method and advances toward a network of networks Howland & Bluhm - Linux Foundation 2022-05-02
With the groundwork complete, networks and agent frameworks now need to incorporate the Indy:DID Method. This community adoption will increase the viability of the Indy and Aries project stack and position it to be the globally dominant way to issue and share verifiable credentials in a multi-ledger world.

- Technical Design and Development of a Self-Sovereign Identity Management Platform for Patient-Centric Healthcare Using Blockchain Technology Blockchain Healthcare Today
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).
