Описание: What Is Hyperledger? The Most Comprehensive Video Series!

Hyperledger Fabric is one of the most widely used private blockchains, but what is it used for, and how does it work?

What is Hyperledger? Let’s start with what Hyperledger is not: Not a company. Not a cryptocurrency. Not a blockchain. Hyperledger is rather something like a hub for open industrial blockchain development. On its website Hyperledger explains: “Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing, and Technology.” Hyperledger does not support Bitcoin or any other cryptocurrency. But the platform is thrilled by blockchain technology. Not since the Web itself, the website tells, “has a technology promised broader and more fundamental revolution than blockchain technology.” Blockchains has the potential to “build a new generation of transactional applications that establishes trust, accountability, and transparency at their core while streamlining business processes and legal constraints.” So we have a lot of promises – and we have Hyperledger. With it, the Linux Foundation aims to create an environment in which communities of software developer and companies meet and coordinate to build blockchain frameworks. The Linux Foundation founded the platform in December 2015. In February 2016 it announced the first founding members, in March 2016 ten more members joined. Today Hyperledger has an impressive list of more than 100 members. The list covers a wide scope of well know industry leaders. It includes mobility tech giants like Airbus and Daimler, IT-companies like IBM, Fujitsu, SAP, Huawei, Nokia, Intel and Samsung, financial institutions like Deutsche Börse, American Express, J.P. Morgan, BBVA, BNP Paribas and Well Fargo, as well as Blockchain startups like Blockstream, Netki, Lykke, Factom, bloq and Consensys. A lot of the world’s largest companies in Tech and Finance meet at Hyperledger with some of the hottest blockchain startups.
