- An Introduction to Hyperledger
Hyperledger began in 2015 when many different companies interested in blockchain technology realized they could achieve more by working together than by working separately.
These firms decided to pool their resources and create open-source blockchain technology that anyone could use. These far-sighted companies are helping blockchain to become a more popular and industry-standard technology.
Hyperledger was put under the guardianship of the Linux Foundation (for a host of reasons that we’ll talk about later) and has grown rapidly in the last few years.
As of publication date, Hyperledger has more than 230 organizations as members—from Airbus to VMware—as well as 10 projects with 3.6 million lines of code, 10 active working groups, and close to 28,000 participants who have come to 110+ meetups around the world. Through 2017, the project was mentioned in the press an average of 1,500 times a month.
Those of us involved with Hyperledger think the future of blockchain will involve modular, open-source platforms that are easy to use. With Hyperledger, we aim to create an environment that enables us to make this vision a reality.
- Tensions Emerge Between Hyperledger Blockchain Group’s Biggest Supporters
From the sidelines of the enterprise blockchain world, it looks like a tug-of-war has broken out, with IBM and its favored Hyperledger implementation, known as Fabric, on the one side, and the Intel-backed Sawtooth on the other. The latter team also has a budding champion in the form of newly appointed TSC chair, and Sawtooth lead maintainer, Dan Middleton of Intel.

Brian Behlendorf, the executive director of Hyperledger, explains why Hyperledger and the Enterprise Ethereum Alliance have joined each other’s organizations.
- Software Giants Microsoft And Salesforce Flock To Hyperledger Blockchain Consortium > "Yes, THAT SalesForce" @by_caballero
Hyperledger Blockchain Consortium is growing to new heights with two software giants, Microsoft and Salesforce, coming aboard. It is a big move for blockchain, but also for the enterprises buying in.

- Inaugural Hyperledger Global Forum Showcases Strong Community Momentum
For Hyperledger, a project of The Linux Foundation that started less than three years ago, the event is a time to reflect on milestones. Hyperledger has surpassed 260 members, with more than a dozen new members including Citi and Alibaba Cloud announced today. In the last year, Hyperledger launched its 11th project, Ursa, and released development updates to the Hyperledger Burrow, Hyperledger Fabric and Sawtooth frameworks. Additionally, Hyperledger and the Enterprise Ethereum Alliance jointly announced membership in each other’s communities as a way to further bolster enterprise blockchain adoption.

EdX Courses
- Introduction to Hyperledger Blockchain Technologies
This introductory course is carefully curated for nontechnical, business-oriented audiences. It examines blockchains for the enterprise and a number of pertinent use cases from Hyperledger, a global cross-industry community of communities hosted by The Linux Foundation and advancing business blockchain technologies. Hyperledger is incubating and promoting enterprise grade, open source business blockchain software, on top of which anyone can set up apps to meet cross-industry needs.
- Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa EdX - Linux Foundation
Learn how Hyperledger Aries, Indy and Ursa add a necessary layer of trust to the Internet, creating and using independent digital identities rooted on blockchains or other distributed ledgers.
- Becoming a Hyperledger Aries Developer
Develop blockchain-based production-ready identity applications with Hyperledger Aries.
- Developing Blockchain-Based Identity Applications
- Understand the problems with existing Internet identity/trust mechanisms today and learn how a distributed ledger, such as Hyperledger Indy, can be used for identity.
- Discuss the purpose, scope, and relationship between Aries, Indy, and Ursa and understand how these open source blockchain technologies provide reliable self-sovereign identity solutions that add a necessary layer of trust to the Internet.
- Understand the Aries architecture and its components, as well as the DIDComm protocol for peer-to-peer messages.
- Deploy instances of Aries agents and establish a connection between two or more Aries agents.
- Create from scratch or extend Aries agents to add business logic and understand the possibilities available through the implementation of Aries agents.

- Verified.Me is a service offered by SecureKey Technologies Inc., in conjunction with a consortium of seven of Canada’s major financial institutions – BMO, CIBC, Desjardins, National Bank of Canada, RBC, Scotiabank and TD. (Fabric)
- What the EEA and Hyperledger Collaboration Means for Enterprise Blockchain Development
Much more can be done. For example, in the identity area, the Fabric team has developed an attribute-based identity verification mechanism called Identity Mixer that uses zero-knowledge proofs to demonstrate possession of digital signatures and private keys. Using this technology, Mixer allows you to prove you can do something without revealing who you are. On the other hand, if the goal is identity masking without attribute claims, the Ethereum community has been using a much simpler technique called Hierarchical Deterministic Wallet (HD-Wallet), which originated in the Bitcoin community so that you never reuse a digital identifier more than once. This eliminates any ability to correlate transactions over time, while all private keys are derived from a single root secret.
[...]
On the identity front, ideally the identities of an organization would not need to be re-built from scratch each time it joins a new consortium. Using a common decentralized identity system, whether it’s based on Hyperledger Indy or Ethereum uPort, or even based on links to legacy federated SSO systems such as ActiveDirectory or LDAP, makes this possible. Certainly more work is required to make this a reality.
