Blockchain is poised to change IT in much the same way open-source software did a quarter of a century ago. And in the same way that Linux took more than a decade to become a cornerstone in modern application development, Blockchain will take years to become a lower cost, more efficient way to share information between open and private networks.
But the hype around this seemingly new, secure electronic ledger is real. In essence, blockchain represents a new paradigm for the way information is shared and tech vendors and companies are rushing to figure out how they can use the distributed ledger technology to save time and admin costs. Numerous companies this year have been rolling out pilot programs and real-world projects across a variety of industries – everything from financial services to healthcare to mobile payments.
It’s unlikely to be a wholly disruptive technology that attacks traditional business models with a lower-cost solution that overtakes other networking technology quickly, according to Karim Lakhani, a professor of business administration at the Harvard Business School. Instead, Blockchain is a foundational technology, with the potential to create new foundations for economic and social systems, Lakhani said in The Truth About Blockchain, which he co-authored.

Blockchain adoption is expected be slow and steady, as the changes it brings gain momentum, according Lakhani, a principal investigator of the Crowd Innovation Lab and NASA Tournament Lab at the Harvard Institute for Quantitative Social Science. “Conceptionally, this is TCP/IP applied to the world of business and transactions,” Lakhani said in an interview. “In the ’70s and ’80s, TCP/IP was not imaginable to be as robust and scalable as it was. Now, we know that TCP/IP allows us all this modern functionality that we take for granted on the web.
“Blockchain has the same potential.”
What is blockchain?
First and foremost, Blockchain is a public electronic ledger – similar to a relational database – that can be openly shared among disparate users and that creates an unchangeable record of their transactions, each one time-stamped and linked to the previous one. Each digital record or transaction in the thread is called a block (hence the name), and it allows either an open or controlled set of users to participate in the electronic ledger. Each block is linked to a specific participant.
Blockchain can only be updated by consensus between participants in the system, and when new data is entered, it can never be erased. The blockchain contains a true and verifiable record of each and every transaction ever made in the system.
The Linux Foundation has created tools for building out blockchain collaboration networks. And in July, the open-source developer unveiled Hyperledger Fabric 1.0, a collaboration tool for building blockchain distributed ledger business networks, such as smart contracts.
Eén van de initiatiefnemers, Mitchell Hettema, raakt er niet over uitgepraat. <a The Rooftop moet de allernieuwste hippe hotspot van de Maasstad worden. Een plek waar 7 dagen per week van 16.00 tot 23.00 uur geborreld kan worden en een vorkje kan worden mee geprikt van een joekel van een barbecue. ,,Ik heb gehoord dat je er in een uur tijd 2200 hamburgers op kunt grillen,’’ grijnst Hettema
