Design overview for Fabric with proposed enhancements for DID, Indy support
https://docs.google.com/document/d/1ENMO-S7i0ef09IRx5teE-eJbRMFsaKSXEdatcufvjPM/edit
SecureKey Technologies is launching an interoperability initiative aimed at establishing common standards and development frameworks for next generation digital identity networks.
Contributions
We will support the efforts within the Hyperledger and Decentralized Identity Foundation (DIF) communities to help create innovative distributed ledger technologies and digital identity networks. We believe that creating cross-project and cross-network standardization and interop along with common development frameworks represents the next step in transforming the digital identity space. In particular we support, and look forward to contributing to, the efforts of Hyperledger Fabric, Indy and the newly proposed Aries project along with DIF’s Identity Hub efforts.
Contributions will be directed towards the community projects above as well as open project extensions within the TrustBloc initiative.
In particular, we will contribute:
- Hyperledger Fabric performance and customization improvements. We are excited to contribute improvements we learned while building and taking our network operational.
- Enable DIDs to be managed and exposed from Fabric, and more generically enabling document provenance.
- A model for digital identity exchange based on DIDs, Verifiable Credentials, and Hubs.
- Efforts towards interoperability with the newly proposed Hyperledger Aries project, in order to use a Fabric-based ledger and our digital identity model. We think it’s critical to allow variation on top of a common base.
- Tooling and demos to enhance developer experiences building digital identity networks.
About SecureKey
SecureKey builds identity networks like Verified.Me, the Canadian identity sharing Network supported by seven major banks, mobile operators, a major credit agency, and other providers in Canada. Verified.Me provides a user centric, privacy protecting identity platform for services that trust the individual’s identity established at their financial institution and other connected organizations. Users can link in account information across services for a convenient but highly reliable digital identity where information is delivered in real time.
Technical Brief
In the following diagram, we provide an overview of the components related to the TrustBloc initiative. We will follow-up with additional details and data exchange flows.
IBM Cross Border Carrier Payments solution coming
https://finance.yahoo.com/news/softbank-develop-cross-carrier-blockchain-050039037.html
SoftBank is teaming up with IBM to develop cross-carrier blockchain solutions, with the focus on technologies that will allow smartphone users to make local payments when traveling overseas and roaming.
first project being undertaken by the CBSG is the Cross-Carrier Payment System (CCPS), which is aimed to allow mobile-phone customers to pay locally using their devices when traveling outside their home countries.
TBCASoft will be using the IBM Blockchain Platform, IBM’s Hyperledger-powered enterprise blockchain solution.
TBCASoft technology helps “optimize” clearing between different carriers and transaction records, according to the announcement, and allows for the interoperability of mobile networks and the bolting on of networks of merchants to enable payments

Food Trust Value List
| Value | Features | Description |
|---|---|---|
| Safety | Transparency Traceability | Trace food instantly – with end-to-end supply chain data visibility – to help ensure food safety and regulatory compliance. |
| Supply chain efficiency | Shared immutable ledger | Access a shared and immutable digital ledger in real time – rather than ink on paper – to find choke points and uncover opportunities to speed your supply chain. |
| Food Freshness | Traceability Shared data | Gain instant and efficient food tracing from source to consumer to more accurately judge peak freshness and remaining shelf life – and reduce product loss. |
| Sustainability | Shared data Immutable ledger Smart contracts | Rely on shared data and an immutable ledger to help ensure the promised quality of products and that food comes from a sustainable source. Smart contracts improve data quality |
| Brand Trust | Transparency Traceability | Gain a competitive advantage as you add transparency and specificity about the sourcing of your food products. Build trust in the safety and quality of your brand. |
| Food waste | Shared data | Identify waste hot spots and speed responsiveness using better visibility into your food supply chain. Reduce costly food waste and boost your bottom line. |
| Food Fraud | Shared data Immutable ledger Smart contracts | Data-sharing across the food supply helps eliminate chances for fraud and errors – and can help preserve the integrity of raw materials, products, and packaging. |
Verified.me - a secure blockchain identity framework for Canadian banks on IBM Blockchain
Verified.Me, by SecureKey Technologies Inc., is the new and secure way to help you verify your identity, so you can quickly get access to the services and products you want online, in person and on the phone.

Fetch.AI - smart blockchain tokenomics framework
Agents
Fetch.AI is a decentralised digital world in which useful economic activity takes place. This activity is performed by Autonomous Agents. These are digital entities that can transact independently of human intervention and can represent themselves, devices, services or individuals. Agents can work alone or together to construct solutions to today’s complex problems.
Open Economic Framework
The digital world in which agents live is called the Open Economic Framework (OEF). This world acts as the ultimate value exchange dating agency: each agent sees a space optimised in real-time just for them, where important things are clear and visible and less important things are simply removed. The OEF provides the senses for agents: their sight, touch and hearing to present to them a world unique to the viewer.
Smart Ledger
Underpinning the digital world is the smart ledger: a new generation of learning ledger that provides a collective super-intelligence to support agents’ individual intelligences. It provides market intelligence, previously locked up in centralised silos, to everyone so that any agent that wants something is assured of the shortest possible route to find another that has it. Fetch.AI’s smart ledger scales to support millions of transactions per second and is able to restructure itself to present the OEF’s digital world to the agents that use it.
