How to Create New Verifiable Credentials with Customizable Schemas
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.
- Anonymous Credential Part 1: Brief Overview and History
An anonymous credential (Anoncred), which is also known as an attribute-based credential (ABC), is a concept for a digital credential that provides a credential holder maximal privacy and an ability to selectively disclose their personal information.
- Anonymous Credential Part 2: Selective Disclosure and CL Signature
selective disclosure and an anonymous credential (Anoncred) relies on an efficient signature scheme that supports multiple messages with a single signature. One such signature scheme is known as CL signature that is named after its Jan Camenisch and Anna Lysyanskaya […] CL signature popularized Anoncreds, and it also served as a cryptographic building block in Identity Mixer (Idemix) and Hyperledger Indy projects.
- Forbes “Blockchain 50” Shows Enterprise Blockchain’s Footprint and Impact, with Hyperledger Tech Leading The Pack
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 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.

- Become a Node Operator Indicio
we’ve seen a rapid rise in demand for robust, stable, and professionally maintained networks to support decentralized identity solutions. It’s not a surprise: decentralized identity’s moment has arrived. That’s why we’ve been hard at work creating Hyperledger Indy networks upon which developers all over the world are building, testing, and launching their solutions.
- Hyperledger Ursa code review Hyperledger
Rooted in a “trust but verify” mindset, several Canadian public sector entities and Interac (Canada’s interbank network) sponsored a project at the Digital Identity Laboratory of Canada (IDLab) to perform a security and cryptography code review of Hyperledger Ursa (full report is available here).
The new Hyperledger Aries Framework JavaScript release (0.2.0) contains some incredible steps forward. Especially in our goal to make the framework AIP 2.0 compliant. AIP 2.0 compliance will not only ensure the framework supports the latest standards and protocols, but it will also greatly increase interoperability and make it more useful outside of the Hyperledger Indy ecosystem.
“This approval is further evidence that Hyperledger Aries is a breakout success for the Hyperledger community,” said Brian Behlendorf, General Manager for Blockchain, Healthcare and Identity at the Linux Foundation. “Convergence on common libraries for the exchange of credentials will help speed the development of urgently-needed solutions and systems, ranging from education to finance to the fight against the pandemic. Aries is key to that convergence.”
The TSC commended the Aries project during the meeting for the project’s highly diverse contributors. Achieving a high number of organizations contributing to a project at Hyperledger is often a challenge. Congratulations are due to those participating in and supporting the Aries Project.

- Indicio Wins British Columbia Code With Us Challenge to Upgrade Hyperledger Indy
Most of Hyperledger Indy’s development occurred prior to the completion of the standard DID Specification by the W3C and, as a result, identifiers written to one network are currently not resolvable on other networks. A new did:indy DID Method will fix that and make it easier for decentralized identity products and services to interoperate across different Indy networks.
- Hyperledger SSI Ecosystem Jakubkoci
There are three projects under the Hyperledger umbrella related to digital identity. Hyperledger Indy, Aries, and Ursa. [...] describe their purpose and how they’re related to each other.
Aries \ Indy \ AnonCreds the dialogue continues
Standards such as OIDC and mDL are all now in dialogue with W3C, AnonCreds, Aries, etc. Mobile is a predominant technology, just like the way laptops were once upon a time. To reduce consumer friction and drive adoption, convergence of all these different technologies is required inside a mobile environment
The Indy DID Method paves the way for Hyperledger Indy credentials to scale globally by allowing Indy networks to seamlessly interoperate and create a “network-of-networks” effect.
- Our Approach to Resources on-ledger: Using the capabilities of the DID Core specification for standards-compliant resource lookup
Decentralised Identifiers (DIDs): are often stored on ledgers (e.g., cheqd, Hyperledger Indy, distributed storage (e.g., IPFS in Sidetree), or non-ledger distributed systems (e.g., KERI). Yet, DIDs can be stored on traditional centralised-storage endpoints (e.g., did:web, did:git).
While no technology runs perfectly on every device, a signal strength of Aries, AnonCreds, and Indy is that they work on the vast majority of current devices and systems, including $35 smart phones and low powered IOT/embedded devices. They represent the most inclusive way into this technology, which is an important factor in their popularity.
- AnonCreds Indy-Pendence Cheqd
Part 1: Decoupling the reliance on Hyperledger Indy and creating more extensible AnonCreds Objects with cheqd.
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 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.
The Hyperledger Mentorship Program is a structured hands-on learning opportunity for new developers who may otherwise lack the opportunity to gain exposure to Hyperledger open source development and entry to the technical community.

- 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).
