Initial POC bootstrapped using Hyperledger Fabric and Hyperledger Composer for ease of use and shortened onboarding time. However, after delving deeper into the tooling and the stack, some shortcomings were identified with regard to the current Hyperledger Fabric implementation that will complicate their MVP roadmap. Greenstream is currently finishing the MVP on Hyperledger Burrow and making good progress.
Hyperledger Burrow was chosen for the following reasons:
– Currently in sprint for version 1.0
– Built on top of Tendermint consensus protocol
– Strongly deterministic smart contract engine for operating complex industrial processes makes it perfect for payment rails (read future proof)
– EVM allows for elegant token design
– First to market with many non-trivial applications in production
– Development and feature ramp up coincides with our timeline, including data privacy in Q2
– Familiarity within members of our development team
– Great community support and direct contact with maintainers
Currently finishing the MVP and going alpha in the next few weeks. View the roadmap here.

MonetaGo has deployed India’s first enterprise blockchain network being used in day to day operations by multiple financial services organizations. The production system, built on Hyperledger Fabric, provides a common distributed ledger platform which is not controlled by any one financial institution. The network enables participants securely share information in real time in order to reduce fraud around receivables financing.
Receivables financing is one of the fastest growing trade finance mechanisms for small businesses to obtain credit. The Reserve Bank of India (RBI) licensed three entities to provide a more efficient venue to do this: RXIL, A.TReDS, and M1xchange. MonetaGo worked with the three exchanges to deploy the blockchain network which does not use tokens or cryptocurrencies of any kind. By implementing a common blockchain platform, these exchanges were able to eliminate instances of double financing without sharing specific elements of any invoice or client.
Keep in mind, these three Indian exchanges are competitors. Their clients are particularly sensitive about their sourcing inputs, and it is imperative that the exchanges not provide any of their client information to a shared registry controlled by any one entity. By creating a blockchain network built on Hyperledger Fabric, together with some intelligent cryptography, that concern is eliminated as the technology enables the exchanges to work together on a shared network to achieve shared goals without compromising privacy.
Initially, the distributed ledger network is being used by three TReDs exchanges in India: RXIL, A.TReDS, and M1xchange. RXIL is a joint venture promoted by National Stock Exchange of India and Small Industries Development Bank of India. A.TREDS is a joint venture of Axis Bank (India’s third largest private bank) and mjunction (the largest e-marketplace for steel in the world and also India’s largest e-commerce company which is itself a venture promoted by Tata Steel and SAIL). M1xchange is a leading global service provider in business process and technology management, offering broad spectrum of services in Finance and Accounting. More exchanges are scheduled to join the blockchain network in the coming months.
TReDS is an online mechanism for facilitating the financing of trade receivables of Micro, Small & Medium Enterprises (MSMEs) through multiple financiers. It enables discounting of invoices raised against large corporate, allowing them to reduce working capital needs.
The participating TReDs exchanges needed a common platform to prevent the customers from obtaining multiple financings against the same set of invoices. By implementing a common blockchain platform, these exchanges were able to eliminate instances of double financing without sharing specific elements of any invoice or client. The technology not only identifies when an exact duplicate has been financed, but even when a similar invoice has been financed which notifies the relevant party they may want to do further due diligence.
Increased Capital Access:
Due to the blockchain implementation, exchanges can ultimately offer better rates across the board to all of their customers, and provide access to capital for more businesses otherwise deemed too risky.
Digital Fingerprinting (Privacy):
The clients of the three competitive exchanges on the blockchain network are particularly sensitive about their sourcing inputs, and it is imperative that the exchanges not provide any of their client information to a shared registry controlled by any one entity. By creating a blockchain network built on Hyperledger Fabric combined with cryptography, that concern is eliminated. To accomplish this, MonetaGo hashes all invoice details and shares a digital fingerprint among the exchanges. As a result, no secret or private information is shared among the three competing exchanges.
Hyperledger Fabric is one of the most mature DLT platforms that does not require the use of tokens. Our use case is not designed to transfer value or ownership of any asset between participants, so the need for tokenization in our solution is absent. Fabric was designed with flexibility in mind, to meet the needs of generic enterprise DLT applications. This means the platform can be configured to fit the solution, instead of the solution being configured to fit the platform. The maturity and community behind Fabric also gives confidence in the continued progression and longevity of the platform.

The National Association of Realtors (NAR) is America’s largest trade association, representing 1.3 million members representing approximately 1,200 local associations and 54 state and territory associations. All these organizations are independent, even though they work together. There is no centralized database containing information about members.
While sharing information about members’ engagement is important, it is difficult to get 1200 organizations to agree to contribute to one database and give up control of their data. That is where distributed ledger technology comes in.
NAR used Hyperledger Fabric to build BlockR, a blockchain-based tool for recording and sharing information about member engagement across the nation’s realtor associations. Searching for member engagement now takes seconds, where it used to take hours of emails and phone calls. In the week following the presentation of the pilot in March 2018, 51 associations asked to be part of it.
Administrators and members of the various realtor associations.
Every year, our volunteer leadership changes at all 1200 organizations. There are about 65 committees, with up to 5 persons per committee. We noticed that we ended up drawing on the same people over and over again.
Now with the easy search for member engagement, we expect that we will both dramatically cut down the time needed to draw up lists of candidates, and increase the diversity of candidates. In the end, it is about providing the best possible opportunities for our members.
Hyperledger Fabric and Hyperledger Composer
Due to the nature of our challenge, we were looking for a distributed ledger technology that is open-source and allows permission-based access. The combination of Fabric, Fabric-CA, and Composer provided tools which significantly reduced development time. Because we are early adopters, we were concerned about maintenance on the underlying business model. Composer provided an easy mechanism to update the business logic as well as support a REST API. Weighing these requirements, Hyperledger was the only contender.

Using in logistics, with IoT, commodities, implementation with own docker images by changing peer values and organization as well as orderer.
Blockchain has 3 principles:
• Transparency & collaboration
• Decentralisation & consensus
• Security Immutability & Encryption
Blockchains benefit the supply chain sector in various ways, most notably by:
1. Automating the purchase process. With blockchains, automatic contracts (smart contracts) can be set up. Once the conditions agreed upon by the users are met, these smart contracts automatically execute their terms– service payment, shipment authorization, etc.
2. Improving transaction flow. Validation times for transactions between providers and clients (contracts, signatures, orders, payments, etc.) are drastically reduced. Result: virtually real-time management of flows and relationships with business partners.
3. Securing the supply chain. Attributing a tag to each product recorded in a blockchain enables you to secure your supply chain in the blink of an eye. Origin, place of storage, authenticity, property certificates, records: all the necessary information is in a single ledger!
4. Ensuring integral traceability. Blockchains ensure the traceability of flows and goods by recording all transactions made by users. These records are indestructible and constitute a tamper-proof evidence that guarantees the integrity of information.
5. Being more reactive. Blockchains can help you detect fraud by identifying problems from the very start of the transaction (inconsistencies with validation, suspicious identity of a party, etc.). In the event of product recovery, an alert is instantly sent.
6. Streamlining internal documents. The validity of information shared among partners prevents the creation of multiple versions of a document. Each party involved in the transaction thus has access to the same data

Hyperledger Fabric considered the basic and perfect build.
I personally tend to put too much time into looking for a domain name too early in the project (because it’s fun to do, honestly). It’s much better to at the very least do serious research first (competitors, understanding and talking to possible customers, etc.), and have done proof-of-concept work for technical challenges, and done some design on your minimum-viable-product first version before worrying about a domain name, because it’s so frequent to find some serious problem during that process that will cause you to abandon the project (or perhaps realize that you don’t find it as interesting as you thought initially — if you don’t have some serious passion for solving this particular problem, it’s not likely you’ll have the motivation to get through the hard parts of building a business around it!).
I’m just working on the production level at the moment with usage of Hyperledger Caliper as to check latency rate and payload.

Sony Global Education provides new educational experiences that stimulate learners’ curiosity. It has identified the need in Japan to create a more comprehensive, open, and trusted system for recording the education and training credentials of Japanese citizens. In doing so, it has also identified that this need exists across the globe. Sony Global Education prototyped a blockchain solution built on Hyperledger Fabric to develop a next-generation credentials platform. The prototype achieved all the needed functionality.
Sony Global Education is collaborating with the Japanese Ministry of Internal Affairs and Communications to demonstrate a next-generation school ICT environment for managing digital transcripts based on the prototyped and tested blockchain solution.
Sony Global Education required several capabilities that would enable a consortium of government agencies and private organizations to collaborate via a single system for storing and retrieving education and training data. Most importantly, it required the ability to keep some information hidden and the ability to manage data access.
Sony and a selected technology partner researched permissioned blockchains that could support a consortium of collaborators. They identified the need to use smart contracts for managing data access, data partitioning to keep some information hidden from some collaborators while exposing it to others, and an open source platform to avoid vendor lock in. This concluded with a decision to use Hyperledger Fabric.
it is a general-purpose business platform and open source project that can support smart contracts via chaincode and data partitioning via channels. The team had considered other platforms, but eliminated them from the running over concerns about security aspects like data access control as well as concerns about being ready to withstand actual operation. Hyperledger Fabric was also selected because it allows for more flexible data models and business logic compared to other blockchain solutions. When Hyperledger Fabric v1.0 was released, the team was confident that it could meet all of the team’s requirements.
Now in phase three, Sony Global Education plans to put the credentials platform to the test by using it to manage educational data generated by 250,000 participants in a world wide math competition called Global Math Challenge, which is held online and hosted by Sony Global Education.

NEXT Identity Platform is a hybrid-architecture Identity and Access Management (IAM) platform built on Hyperledger Sawtooth. With a Node.JS UI built to an OpenAPI Swagger, this identity platform uses a RethinkDB as a caching layer for high-speed API access, and a custom sync engine to write transactions to the blockchain back-end. Future opportunity to integrate with identity portability/verification chains such as Hyperledger Indy provide an exciting path forward for this foundational technology.
Initial customer/user is for T-Mobile internal use. Opportunity to deploy both in existing organizations to improve identity management, or in new green-field scenarios as an identity management foundation for any business or application give this project a uniquely broad deployment potential.
This solution provides a strong foundation for highly automated easy-to-use identity and access management with improved security, transparency, and auditability versus existing applications.
The Hyperledger Sawtooth foundation provides a strong blockchain with opportunity to implement PoET Consensus Algorithm and enclave-based leader election and key management.

TEKO as a corporate unit has been founded in 2014. The mission of the company is to provide a distributed processing service to accept cash and non-cash payments from customers to service providers, banks and merchants by using a blockchain technology.
In 2018 we have became a Skolkovo member with project “A distributed processing platform”. We have signed contracts with Tele2 mobile operator (more than 2500 points of sale in Russia) and major merchants like Avito and etc. Our main idea is to transfer processing system to the merchant side, providing direct integrations with payment gateways, and use distributed registry technologies as database. We hope to open our data to all participants and make reconciliations more efficient. We investigate in Hyperledger and Corda.
Service providers, banks and merchants
1. Additional nodes in the processing chains of payments are excluded. Potential points of failure are excluded. A merchant processes payments on its own side through a direct channel with a payment gateway. This technology will reduce transaction costs and offer more favorable fees, increase system resilience and payments conversion.
2. Any user has a single integration, single technical protocol and a single contract with a single bank to process all payments by all methods.
3. Any user has a complete control of all contract terms. There is no a single party of a contract that can change the financial terms of the contract by itself.
4. To guarantee a quick start of the payment system. The platform integrates by itself all the popular cash and non-cash payment providers.
5. We implement an automated reconciliation procedure. This gives us a good opportunity to increase speed and transparency of all the financial settlements. An electronic document management has been made fast, user-friendly and legal with respect to the actual Russian laws and the Government regulations.
