The developerWorks TV team has been working hard on our blockchain topic page the past few weeks and it’s really starting to pay off. With so much hype being written about blockchain these days we wanted to create a topic page that will separate the fact from the hype and give people a sincere and thoughtful look at blockchain technology, how it works, what it means for business and what it means for developers.

Here are some of my favorite highlights from the Blockchain topic page:

Developer Perspectives on Blockchain


blockchain developer perspectives

This eight part series features three of IBM’s blockchain developers discussing their views on blockchain technology in a chalk-talk style setting. I am particularly proud that dW TV is able to host the “What Is Blockchain” video on that page. It is, in my honest opinion, the most clear and concise explanation of blockchain technology I’ve ever seen anywhere. The three developers discuss their favorite blockchain applications they’ve seen at recent hackathons including a ground-breaking utility energy app and an interesting supply chain app that inspired them. They also talk about the realities of getting started with blockchain from a developer’s perspective.  I highly recommend this series for anyone who wants a developer-to-developer discussion on blockchain.

Architect Perspectives on Blockchain

In parallel with the series on developer perspectives, we also have the Architect perspectives on blockchain. This extended interview features IBM’s John Wolpert, who serves as IBM’s BM Blockchain Operating Director and Kelly Olson, who is Director of the Distributed Ledger Technology Group at Intel. The interview was held at FinTech week in San Francisco and they have a very frank and open discussion about blockchain. They discuss bandwidth issues that the technology generates. They discuss the need for not only open source, but open governance in blockchain fabrics. They also discuss the Hyperledger Proejct at the Linux Foundation as well as R3. They discuss approaches to dealing with “bad actors” in a blockchain distributed ledger and offer guidance to companies who want to take a first step toward the technology.

Blockchain Demo Videos

The blockchain topic page also has an excellent collection of use case scenario demos that will inspire you and spark your imagination on how you can use the technology:

The Blockchain Car Lease Demo: This is the prototypical supply chain scenario for blockchain. You’ve got large, physical, expensive assets that need to be tracked throughout their lifecycle from the manufacturing line to the scrap heap. There are hundreds of types of actors that have and interest and stake in the ownership, makeup, and current condition of the assets and all of the actors can benefit from a transparent, yet permissioned distributed ledger.

The Trading Commercial Paper Demo: This demo looks at blockchain from a wildly different perspective, one where the assets are not physical, but are financial instruments. Here the issues have more to do with tracking ownership and making sure transactions are cleared in a timely and efficient way.

The System z Accelerator Demo: This demo looks at the comuptational underpinnigns of blockchain technology and show how the “big iron” systems have the specialty hardware and corresponding compute power to handle even the longest blockchains so that validation of transactions is handled at the best possible speed.

Discussion Videos

The blockchain topic page also has a wide variety of videos from IBM luminaries who will show you where and how IBM is contributing to the success of blockchain at enterprise scale.
