Blockchain is currently at the peak of the Hype Cycle. It is a simple concept, yet difficult to understand and comprehend. It is also in the same place as the Internet was in 1995 – very early, with its major applications yet to be built. Blockchain is a much a philosophy as a technology, and has the potential to change the world as the Internet did. It promises to radically transform identity, agriculture, money, energy, governance, and pretty much everything else, especially in the emerging countries. This TEDx talk demystifies blockchain as never before, and explains how it can change the world around you… Jaspreet Bindra is a digital transformation and Blockchain expert. Until very recently, he was the Chief Digital Officer of $20bn Mahindra Group; and he continues as their Digital Adviser. He speaks, writes, teaches and consults on Digital Transformation and Blockchain, and is currently building a company around the same. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

At IBM InterConnect 2016, Kathryn Guarini, Vice President, Offering Management for z Systems and LinuxONE, discusses the idea of cross-industry solutions, of which Blockchain is one. Blockchain is seen as the main technological innovation of Bitcoin, since it stands as proof of all the transactions on the network. A block is the 'current' part of a Blockchain which records some or all of the recent transactions, and once completed goes into the Blockchain as permanent database.
Ms. Guarini introduces Donna Dillenberger, IBM Fellow, who talks about Blockchain and its impact on various industries including financial technology . Ms. Dillenberger explains why you would want to run Blockchain on IBM z Systems. For more information about IBM z Systems and Blockchain visit IBM on the web at http://www.ibm.com/blockchain/z.html
Blockchain, the key technology behind Bitcoin, is a new network that helps decentralize trade, and allows for more peer-to-peer transactions. WIRED challenged political scientist and blockchain researcher Bettina Warburg to explain blockchain technology to 5 different people; a child, a teen, a college student, a grad student, and an expert.

Blockchain explained in plain English
Understanding how blockchain works and identifying myths about its powers are the first steps to developing blockchain technologies.
Blockchain is an algorithm and distributed data structure for managing electronic cash without a central administrator among people who know nothing about one another. Originally designed for the crypto-currency Bitcoin, the blockchain architecture was driven by a radical rejection of at (government-guaranteed) money and bank-controlled payments.
Blockchain is a special instance of Distributed Ledger Technologies (DLTs), almost all of which have emerged in Bitcoin's wake.
HOW DOES BLOCKCHAIN WORK?
Blockchain is a Distributed Ledger Technology (DLT) that was invented to support the Bitcoin cryptocurrency. Bitcoin was motivated by an extreme rejection of government-guaranteed money and bank-controlled payments. The developer of Bitcoin, Satoshi Nakamoto envisioned people spending money without friction, intermediaries, regulation or the need to know or trust other parties.
Technically, the original blockchain is separable from Bitcoin, but this report will show that the blockchain design is so specific to Bitcoin that it's not a good fit for much else.
The central problem in electronic cash is Double Spend. Because pure electronic money is just data, nothing stops a currency holder from trying to spend it twice. Blockchain solves the Double Spend problem without a digital reserve fund or similar form of umpire.
Blockchain monitors and verifies Bitcoin transactions by calling upon a decentralized network of volunteer-run nodes to, in effect, vote on the order in which transactions occur. The network's algorithm ensures that each transaction is unique.

Talks at Google in London were delighted to welcome Alex Tapscott to talk about his book Blockchain Revolution, looking at how the technology behind Bitcoin can reshape the world of business and transform the old order of human affairs for the better.
Alex can be found on Twitter at: @alextapscott
Book on Google Play - with free first chapter!
About the Book:
The technology likely to have the greatest impact on the future of the world economy has arrived, and it's not self-driving cars, solar energy, or artificial intelligence. It’s called the blockchain.
The first generation of the digital revolution brought us the Internet of information. The second generation powered by blockchain technology is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better.
Blockchain is the ingeniously simple, revolutionary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value. Though it's the technology that drives bitcoin and other digital currencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certificates to insurance claims and even votes.
Why should you care? Maybe you're a music lover who wants artists to make a living off their art.
And those examples are barely the tip of the iceberg. This technology is public, encrypted, and readily available for anyone to use. It's already seeing widespread adoption in a number of areas. For example, forty-two (and counting) of the world's biggest financial institutions, including Goldman Sachs, JPMorgan Chase, and Credit Suisse, have formed a consortium to investigate the blockchain for speedier and more secure transactions.
As with major paradigm shifts that preceded it, the blockchain will create winners and losers. And while opportunities abound, the risks of disruption and dislocation must not be ignored.
