can enroll in “Blockchain
for Business — An Introduction to Hyperledger Technologies.” It is an
introduction to the Hyperledger ecosystem, which consists of various
frameworks. They should expect to walk away with an understanding of common
Hyperledger use cases, how to install its various frameworks and how to build
simple applications on them. One useful takeaway will be information on how to
contribute to the open-source project.
Hyperledger launched anyway and why should you care? The problem with the blockchain
is that there are no standards for it. There may be heavily adopted and
supported projects, such as the Bitcoin blockchain and Ethereum, but the Linux Foundation,
which specializes in reference implementations, wanted code that would effectively
be the Linux of the blockchain world.
agreed, because they contributed their own code to it. IBM pitched in some of
its own blockchain code, as did Intel, and Digital Asset Holdings (DAH),
financial blockchain company, also submitted code. Blockstream, which
specializes in side chains, was another supporter.
Behlendorf, who took the helm at the project in spring 2016, measures the
project’s success in part by how much interest it garners for its technical
steering committee. After all, the more companies that are using it, the more
of a hand they will want in its development.
“This year we had
360 non-trivial contributors who then formed the elector pool,” he said. “That
grew by a factor of three.” (There were a little over 100 last year.)
success is also evident in the work it has published. It has produced several frameworks,
the major one of which is Fabric. Released as version 1.0 in July 2017, this is
the production-ready, open-source distributed ledger platform — the bedrock for
Hyperledger — and it uses the IBM and DAH code.
Sawtooth: a platform based on Fabric for building business blockchain
applications and which has more user-facing services for those developers to
take advantage of. Students of the edX course will learn how to create clean
installations of both these environments and use them to build rudimentary
services, Hyperledger also has Indy, which is its identity management
framework. ID management will be an important part of most blockchain-based
services, and some use cases stand out. Behlendorf pointed to managing
identities for refugees as an example.
following the edX project will doubtless also learn about Burrow, which is a
Hyperledger foray into smart contracts. The project already supported smart
contracts written in Go, a programming language, directly in Fabric using a
Docker container, but Burrow is a smart contract interpreter that tries, in
part, to follow the specifications of the Ethereum virtual machine (EVM).
began on October 24, 2017. It lasts eight weeks and requires three to four
hours of effort each week. The Foundation has brought in trainers from
blockchain education firm DLT.Education to
steer the course, along with lawyers and fintech entrepreneurs.
edX said that
the course is aimed at both technical and non-technical types, meaning that if
you’re an entrepreneur, it will give you an idea of how blockchains work and
the kinds of use cases that they might support.
