Cisco says blockchain ledger technology has networking role – TechTarget

Cisco predicts blockchain ledger technology could play a role in managing networks built on switches, firewalls and other appliances from multiple vendors.

Cisco believes blockchain is likely to play a significant role in network management with early adopters of the distributed ledger technology surfacing within three years.

Cisco is helping to steer blockchain’s ascendancy in networking through membership in industry development efforts. Last week, the company joined the governing board of the Linux Foundation’s Hyperledger Project, an open source initiative to develop cross-industry blockchain technologies. The 18-member board includes big names in finance, banking, manufacturing and technology. Other tech vendors in the blockchain ledger effort include IBM, Intel and SAP.

Today, blockchain is used to create a permanent, tamper-proof ledger of cryptocurrency transactions. The virtual currency that uses blockchain for record keeping includes Bitcoin, Litecoin and Namecoin.

But the record-keeping capabilities of blockchain ledger technology also make it useful in managing network appliances built by different vendors. Examples include switches, routers, firewalls and internet of things gateways. “[Basically,] any device that has the ability to host a blockchain client,” said Anoop Nannra, the head of Cisco’s blockchain effort.

Fujitsu develops technology to accelerate transaction processing on blockchain – EconoTimes

Fujitsu Laboratories Ltd., a wholly owned subsidiary of leading Japanese information and communication technology (ICT) company Fujitsu Limited, has announced the development of a technology that speeds up transaction processing for Hyperledger Fabric, one of the Hyperledger blockchain frameworks hosted by The Linux Foundation.

The newly developed technology accelerates transaction processing by making the processing of communications between applications and the blockchain platform more efficient. According to the official release, a trial in which this technology was implemented in Hyperledger Fabric v0.6.1(1), resulted in an increased transaction performance by approximately 2.7 times compared to the previous method.

Fujitsu noted that the number of transactions that can be executed per unit of time is currently limited by communication bottlenecks through the blockchain network. This makes it difficult to apply the technology to online transaction systems, which demand to process large volumes of transactions.

In order to overcome this limitation, Fujitsu Laboratories developed two technologies to improve transaction performance speed by reducing the number of communications between the applications and the blockchain platform. Features of the newly developed technologies include:

  • Differential Update State (DUS) Functionality: Fujitsu Laboratories has developed functionality that executes only differential computations on the specified data, in one processing action on the blockchain platform, and functionality that reduces the number of computations directly linked with the number of communications.
  • Compound Request (CR) Functionality: Fujitsu Laboratories has developed functionality to aggregate multiple processes to send to the blockchain platform for batch execution. This functionality makes processing on the blockchain platform more efficient by aggregating multiple processes and also reduces the number of communications.

R3’s Richard Brown: IBM should adopt Corda – International Business Times

Richard Gendal Brown, chief technology officer at R3, was previously executive architect for banking and financial markets at IBM.

Richard Gendal Brown, the chief technology officer at R3, believes IBM should adopt Corda, the shared ledger platform his engineering team has built for its 80-plus member banks.

Brown, who was formerly executive architect for banking and financial markets at IBM and worked there for over 15 years before joining R3, does not make this statement lightly; it follows a close examination of the latest version of Hyperledger Fabric, the open source consortium platform which is IBM’s preferred blockchain.

He makes it clear it’s not his policy to be critical of another project until he has studied it closely and identified what he considers to be fundamental problems with its design. And he recently published his analysis of Fabric, paying particular attention to its privacy channels solution.

IBM-Backed Hyperledger Releases New Blockchain Code ‘Fabric’

Companies of all sorts are scrambling to create standardized versions of blockchain software and, on Tuesday, one group of them reached a major milestone in the space by releasing its vision of blockchain to the public.

The software, known as Fabric 1.0, has been stitched together over the last year by an outfit called Hyperledger, which represents the efforts of IBM and other companies to deploy a blockchain tool that can do things like track food shipments or keep track of diamond sources.

If you’re unfamiliar, blockchain is a software-based ledger system that uses multiple computers to create an indelible, tamper-proof record of transactions.

The most famous example of blockchain in action is the cryptocurrency bitcoin but companies of all sorts—including banks, tech firms, and retailers—have been building their own “chains” in the belief they will dramatically improve supply chains and lower the cost of record keeping.

Hyperledger Brings Healthcare Blockchain Closer with Fabric 1.0 – HealthIT Analytics

Hyperledger has released the first version of a blockchain development platform, opening up opportunities for the technology to find a home in healthcare.

July 11, 2017 – Developers interested in bringing blockchain applications to the healthcare industry have a new arrow in their quiver with the release of Hyperledger Fabric 1.0.0, the first publically available version of the consortium’s open source blockchain framework.

Fabric creates a plug-and-play environment for building blockchain applications, allowing developers to take advantage of a module architecture for components such as membership services.

“Hyperledger Fabric 1.0 is a true milestone for our community,” said Brian Behlendorf, Executive Director, Hyperledger.

“After over a year of public collaboration, testing, and validation in the form of POCs and pilots, consumers and vendors of technology based on Hyperledger Fabric can now advance to production deployment and operations. I look forward to seeing even more products and services being powered by Hyperledger Fabric in the next year and beyond.”

The framework is the first of eight projects being incubated by Hyperledger, and is the first to move into “active” status earlier this year.

More than 200 engineers, writers, and testers from dozens of organizations participated in the development and testing of Fabric 1.0, which represents an initial springboard for application developers in healthcare, finance, manufacturing, and countless other industries.

Linux for Everyone–All 7.5 Billion of Us – Linux Journal

Linux has long since proven it’s possible for one operating system to work for everyone—also that there’s an approach to development that opens and frees code so everyone can use it, improve it and assure its freedoms spread to everyone doing the same.

This has been great for computing at all scales. But, it hasn’t been great for everybody, yet, because not everybody has access to hardware or software, but we can still help them out, our way.

. . .

It hurts that we chose client-server (which might as well be called slave-master) as the defaulted way to deploy the World Wide Web in the first place, and still today. Brian Behlendorf of the Linux Foundation’s Hyperledger project, called client-server “the original sin” of the web when he spoke to Quartz’s The Next Billion conference last October. Hyperledger is a global “open-source collaborative effort created to advance cross-industry blockchain technologies”. It also “incubates and promotes a range of business blockchain technologies, including distributed ledger frameworks, smart contract engines, client libraries, graphical interfaces, utility libraries and sample applications”.

Among Hyperledger’s projects and frameworks is one called Indy that uses what it calls a universal trust framework to provide “accessible provenance for trust transactions”. More specifically, it supports “user-controlled exchange of verifiable claims about an identifier” and “has a rock-solid revocation model for cases where those claims are no longer true”, adding “Verifiable claims are a key component of Indy’s ability to serve as a universal platform for exchanging trustworthy claims about identifiers.”
