Driving Hyperledger was the notion of a blockchain, a distributed ledger whose roots are in digital currency Bitcoin, for the Linux ecosystem - a reference technology stack that those comfortable with a command line could experiment with and build their own blockchain systems and applications. Back in , people were just starting to create proof of concept apps using the prototypical version of what would become Fabric, the core Hyperledger blockchain system.
A lot has happened since then. The Hyperledger stack has grown. July saw the release of version 1. These include Sawtooth - contributed by Intel - for those who want to build their own ledgers. Its consensus mechanism relies on extensions in Intel processors, though, limiting it to that architecture.
The idea here is to provide a decentralized identity system, solving one of the big problems with centralized identity frameworks, which is that the system or a person with centralized access could be compromised. But is anyone actually using it? Financial settlements have been a much-lauded killer app for blockchain ledgers, because it is currently so inefficient. Another oft-cited use case is tracking the provenance of goods.
Everledger, a company that tracks high-value goods, used the IBM blockchain technology underpinning Hyperledger Fabric to create its system. It tracks diamonds across the world using their individual physical footprints, which can be digitally measured. It hopes to reduce jewellery fraud by effectively digitizing the paper-based Kimberley process diamond tracking method.
While uptake of Hyperledger might range somewhere between embryonic and uncertain, the numbers of those expressing support for Hyperledger has certainly grown. Manufacturers are in the tanks, too, with Airbus from aerospace and Daimler from automotive. There are also startup entrants from healthcare, hoping to use blockchain to manage patient records and untangle the complex web of payer settlements in the US healthcare system.
One thing that stands is representation from China. Also on board is Monax formerly Eris. This is particularly notable because Monax bought with it an Ethereum virtual machine to more closely align the Ethereum and Hyperledger communities. That now forms the basis of Burrow, a smart contract module project under the Hyperledger banner. It was already in serious conversations with banks just as Hyperledger was getting started. Ethereum started as a public-focused chain, but it is expanding.
Its launch of the Ethereum Enterprise Alliance in February this year shows that it is getting serious about permissioned chains too. Typically, Ethereum uses the GPL This sticking point alone likely nixes any closer relationships between the two. Traditionally, in this industry, the presence of lots of people in a community talking something up combined with little physical evidence of deployments have been sure signs that the subject in question is being over hyped.
Is Hyperledger, therefore, suffering from a case of hype? That future date should be when, it is hoped, most companies will have both woken up to its existence and managed their expectations about its possibilities. And that may involve engaging with regulators. That might be harder than it looks. Alan Pelz-Sharpe, founder and principal analyst at Deep Analysis and sometime Reg writer, points out a number of challenges.
Remember all those projects? Another issue is acceptance of blockchain itself in the real world, outside that of tech companies. Similarly, getting regulators in various nations to agree to use the blockchain to handle international shipping paperwork — let alone agree on the same standard — will be no mean feat.
He suggests that its heavy-hitter members could be a mixed blessing. We're three years into Hyperledger. The project has come a long way in that time while Behlendorf has form to take it further. Behlendorf sits at the intersection of technology and community building.
On that basis, over the next 18 months, we could see a rounding out of the Hyperledger technology stack and larger-scale deployment projects. Minds Mastering Machines - Call for papers now open. The Register - Independent news and views for the tech community. Part of Situation Publishing.
