Students need to get back to interacting with each other and faculty face to face in order to maximize their education experience; similarly, employees need to interact with each other from time to time in person to generate new ideas, form relationships and build the next best thing together. The post pandemic world will have the effects of the virus with us for a while, so how do we protect each other in a way that also respects our privacy? Verifiable Credentials is one way to do this in order to securely check the status of a vaccination, antibody test or virus test without having to track this in a central database. Hyperledger member company Pravici will discuss how this can be achieved and the practical limitations and issues trying to bring this technology to the fore for Covid mitigation.

They will demo examples, talk about the technology and standards and what the world can expect in the immediate future. Pravici will also touch upon the wide applicability of this technology as Self-Sovereign Identity becomes more prevalent in multiple domains.

In the “Hyperledger In-depth: An hour with… .” series, Hyperledger members share learnings from their projects and try to answer all the hard questions about the pains of working with DLTs. It is not yet another webinar: participants will be encouraged to take part, come with prepared questions and voice opinions. Expect live demos and tutorials, stories from the battle field and hopefully some heated discussions. Let’s get out of the zoom fatigue and engage to share experiences and build a stronger community.

Published Application Launch Hangs at “Connection established. Negotiating capabilities”

During session launch Citrix Profile Management Service identifies if the user should be processed and also determines the path where the User Profile is stored.

If the Policy contains any variables in the User Store profile path, these will be completed at run time. During the logon process a delay occurs for hostname resolution of the profile share during the lookup phase for the user profile path.

Indicio launches blockchain-enabled network for identity

Technology provider Indicio.tech, a public benefit corporation advancing decentralized identity software and solutions, today announced the public availability of the Indicio MainNet, a professionally-staffed decentralized identity network designed for global enterprises that need a reliable platform to develop and scale identity services and products.

The development of the Hyperledger Indy-based network follows on the successful deployment of the Indicio TestNet, a market leader in decentralized identity networks.

The Indicio MainNet uses distributed ledger technology—multiple identical databases spread across different nodes—to enable the use of privacy-preserving verifiable digital credentials. This provides the foundation for flexible, portable, and permanent digital identities that are always under the control of the identity holder—the individual—and which provide an evolutionary leap forward in security.

“Our clients asked for a stable, fully-staffed network based on Hyperledger Indy— one that could provide the Service Level Agreements their customers need for mission-critical workloads,” said Heather Dahl, CEO of Indicio. “Today, we are excited to announce that this MainNet is open for business.”

“This is the network we need to accelerate adoption of passwordless zero trust ecosystems for enterprise customers” said Mike Vesey, President of IdRamp, a leader in decentralized identity and a Genesis Node Operator on the Network. “Our customers are developing service delivery ecosystems that require world class support, and leading edge features managed by a team with deep technical experience. The Indicio network provides exactly that.”

“The Indicio Network enables GlobaliD to deliver a digital identity platform that puts you in control of your identity and your data,” says Mitja Simcic, CTO of GlobaliD, one of the first companies to use Indicio’s MainNet. “Most digital identity platforms take ownership and control of your digital identity and your data for their own purposes. For instance, social media companies make money from selling your data to unauthorized third parties. Indicio is creating an ecosystem for providers that are working to make this practice obsolete. This network is bringing real change to real people, all over the world.”

The Value of Decentralized Identity

Decentralized identity allows individuals to control their own data and solves the privacy and security issues that undermine current models for handling identity online. This privacy-preserving model for identity, where everyone controls their own information, makes it easy for companies and organizations to comply with data privacy laws, makes business partner integrations more secure, and does away with the need for third-parties to manage and hold personally identifiable information (PII).

It is important to note that as part of Indicio’s governance, no personal data, such as names, addresses, or birth dates, are written to any of the Indicio Network ledgers. Instead, machine-readable cryptographic information identifies the issuer of the credential and the details that demonstrate the credential is authentic. With just a few writes to the Indicio MainNet, millions of credentials can be issued, all pointing to the same few ledger writes making the system easily scalable.

How to use the Indicio MainNet

Anyone using technology to verify a verifiable credential that is presented to them may access the Indicio MainNet for free. Several wallets currently in production now point to the Indicio Network, enabling credentials to be issued on, and read from, the Indicio Network.

Global innovators interested in becoming part of the Indicio Network are welcome to become an Indicio Node Operator. This diverse, supportive, and collaborative network of dynamic companies, work together to support a copy of the ledger while helping to advance decentralized identity.

Hyperledger Aries identity tools graduates to active project

On Friday, enterprise alliance Hyperledger announced that Hyperledger Aries is the latest initiative to transition to active from incubation. Given the push towards COVID-19 health credentials, the timing is opportune as Aries provides a set of tools to implement decentralized identity (DID).

“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,” said Brian Behlendorf, GM for Blockchain, Healthcare and Identity at the Linux Foundation.

The production-ready Hyperledger Aries is a relatively new initiative that was motivated but another identity project, Hyperledger Indy. The two communities have the common goal of decentralized identity and verifiable credentials but focus on different technology areas.

Indy provides the network protocol and enables a limited amount of non-private data to be saved on a blockchain. For example, if a COVID-19 testing lab issues a verifiable credential for a test, you might want to check it really was them that provided the credential. To do so, your app would check the public key matches what’s on the Indy-based chain. Indy stores other information such as a list of credentials that have been revoked, for example, if a driver’s license expires.

Turning to the Hyperledger Aries project, it provides a set of tools to create decentralized identity apps. Those tools fall into three buckets, agents, DID communications and protocols.

A mobile app wallet that stores your credentials is an agent. Agents are the technology ‘actors’ that work on behalf of real people or institutions. Some people are happy with self-hosted wallets, while others use cryptocurrency exchanges and banks to store their assets. Likewise, people might decide to store their credentials in the cloud, where another set of tools is needed for this type of agent. In these examples, both the cloud and mobile agents act on behalf of credential holders. But the credential issuer – a lab or the passport office – will also need a technical ‘agent’ to issue the credentials on its behalf.

And the other part of the story is how the agents communicate with each other, which is usually one-to-one or P2P communication.

Some assume the credentials are stored on a blockchain. But with the Hyperledger protocols, that’s not the case. Instead, if a test lab issues a health credential, it would be sent directly to your wallet. For that to happen requires a secure communication method between the lab and your wallet and some agreement about the content of the messages.

Simplistically, DID Communications are the generic ways to communicate. Protocols are a layer on top that involves specific ways applications communicate. For example, how you receive your credentials from a lab, and how you can share them at the airport.

And interoperability is an important part of communication.

Another slightly confusing aspect is how Hyperledger Aries fits in with the Trust over IP Foundation (ToIP), which like Hyperledger, is also part of the Linux Foundation.

ToIP focuses on the bigger picture of what is needed to get decentralized identity more broadly adopted. So it involves the human aspects or, more specifically, the governance that’s needed for various aspects in a DID network, as well as the technology stack.

Meanwhile, ID2020 recently launched the Good Health Pass Collaborative, where both Hyperledger and ToIP are members alongside many other providers. The aim is to ensure credentials are interoperable.

Three examples of travel credentials being rolled out are the IATA Travel Pass, GE’s TrustOne, and the International Chamber of Commerce’s ICC AOKpass.
