Hyperledger is a collective of open-source blockchains and tools hosted by the Linux Foundation and aimed at enabling enterprises to create their own distributed ledgers. Because Hyperledger is open-source, others can freely build on top of it. Large-scale enterprises such as IBM, Walmart and Fujitsu have developed projects using Hyperledger."

The Hyperledger Foundation has released the second version of its open-source distributed ledger (DLT) platform, Hyperledger Fabric.

The Hyperledger Capital Markets Special Interest Group (CMSIG) represents industry professionals working together to study how Hyperledger DLTs interact with Capital Markets use cases. This covers issuance and trading of instruments to continued market-making, management of risk, program-trading, regulations, capital requirements, traceability, post trade settlement, custody including corporate actions and more. This group also explores architecture, identity and performance related considerations specific to Capital Markets and DLTs.

The choice of Stellar is a bit surprising given that IBM has been working with the Linux Foundation on Hyperledger Fabric for years. But Hyperledger Fabric is permissioned, private distributed-ledger technology. IBM wanted something more open that any organization could join if it met certain criteria. In World Wire, IBM has created kind of a virtual private network within Stellar. Organizations can register assets and become part of the network, but IBM carefully vets each participant and validator. By contrast, Ripple says it does not know who runs the validator nodes on its distributed ledger. It's really about knowing the validators, but without creating this walled garden that you have to have special permission to join.

IBM has doubled the number of its employees on the technical steering committee (TSC) of Hyperledger, stoking concerns about the tech giant's influence on the enterprise blockchain consortium.

It seems like Hyperledger and Quorum are currently in their own race to see who will become the leader of the crowd. It turns out, the final verdict may rest in a number of projects including Besu and Adhara.

There are multiple possibilities for distributed ledger technology. This introductory article compares Corda, Hyperledger Fabric, Quorum, Ethereum and Bitcoin, relative to them fighting it out in a battle to determine what would be best suited to the use case of processing distributed transactions in the insurance domain. The considerations include data privacy, scalability and ease of programming.

The National Bank of Cambodia (NBC) partnered with Soramitsu to modernize the country's legacy retail payments using the Hyperledger Iroha blockchain framework. The project, called Bakong, allows users to transfer money and buy from merchants with a simple smartphone app. Merchants gain a fast, cashless, and secure payments system. And banks can do interbank transfers at much lower cost. A pilot project went live in July 2019 and ran successfully with more than 10,000 users. The next step is to let everyone in the country know that the system is available and working, and launch country-wide later in 2020.

The Belarus government-owned Center of Bank Technologies has reportedly initiated the construction of a central bank digital currency (CBDC) platform. The Center also posted a job vacancy for backend developers with expertise in Hyperledger Fabric and smart contract development experience. Plus, last week the National Bank of Belarus Deputy Chairman of the Board reportedly called the digital ruble project a "significant areas of development in the payment sector." https://neg.by/novosti/otkrytj/v-belarusi-nachalas-razrabotka-platformy-dlya-tsifrovogo-rublya/

CIP, a facilitator of Brazilian banking and financial infrastructure, has officially launched its blockchain ID platform via a partnership with IBM using Hyperledger Fabric.

The Eastern Caribbean Central Bank (ECCB) is completing the final testing and assurance exercises following several system upgrades and will make the DCash platform available for public use during the week of March 7. The DCash system has been down since January 14. The interruption was due to an expiring certificate on the version of the Hyperledger Fabric that hosts the DCash ledger, and not to any external intervention. It has taken longer than expected to fix the problem because the ECCB took the opportunity to undertake several upgrades platform including enhancing the system's certificate management processes, and updating the version of Hyperledger Fabric. Other upgrades will allow the platform to process government disbursements to individuals and permit commercial websites to accept DCash. The ECCB says that the security and integrity of all DCash data, applications and architecture, including all central bank, financial institutions, merchant and wallet apps remain secure and intact.

The National Bank of Cambodia's Project Bakong is a Hyperledger Iroha-based payment system renewal project. A pilot with dozens of banks will soon be launched. The ultimate target is to provide instant payments via a mobile app.

IBM is upgrading its enterprise Blockchain Platform to carry over changes in Hyperledger Fabric 2.0 (its base layer) that will improve performance and data privacy, and allow transaction parties to propose and amend smart contract parameters.

Blockchain startup Digital Asset is open sourcing its Digital Asset Modelling Language, the heart of projects like the partial ASX re-plumbing. This will include its source code, runtime system, and software development kit, all under an Apache 2.0 license.

The ECCB CBDC pilot involves a digital version of the EC dollar (DXCD) distributed by licensed ECCU financial institutions. The DXCD will be used for transactions between consumers and merchants, between people, all using smart devices. IBM Hyperledger Fabric was selected as the blockchain platform.

Brazilian banks will be implementing a new standardized blockchain identity solution co-developed by IBM and the central bank, CIP. It is reportedly to be integrated into the Brazilian Payment System.

This article details how CBDC can be implemented, comparing three possible DLT-based options (Corda, Hyperledger Fabric, and Quorum) on privacy, scalability/performance, resiliency and finality.

Blockchain service firm Chainstack recently published a report about developer activity on six major enterprise blockchains, showing that Fabric has overtaken Corda in regard to dev activity on its repository. A chart included in the report shows that Fabric developer activity exceeded Corda's in Q4 2019.

IBM and Hyperledger executives talk about blockchain's potential to create a better supply system.

Ethereum studio ConsenSys will reportedly integrate Quorum into the China state-sanctioned Blockchain Service Network (BSN). The BSN is a service infrastructure that allows developers to build decentralized applications on top of blockchains that it supports, like Hyperledger Fabric, Ethereum, and Polkadot. It is backed by the State Information Center of China, a think tank under the country's cabinet-level economic planning agency, the National Development and Reform Commission. Beijing-based Red Date Technology oversees the operations and development of the platform.
