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.

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.

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.

This talk was given at a local TEDx event, produced independently of the TED Conferences. Tech entrepreneur and mathematician Charles Hoskinson says Bitcoin-related technology is about to revolutionise property rights, banking, remote education, private law and crowd-funding for the developing world.
Charles Hoskinson is Chief Executive Officer at Thanatos Holdings, Director at The Bitcoin Education Project, and President at the Hoskinson Content Group LLC.
Charles is a Colorado based technology entrepreneur and mathematician. He attended University of Colorado, Boulder to study analytic number theory in graduate school before moving into cryptography and social network theory.
His professional experience includes work with NoSQL and Bigdata using MongoDB and Hadoop for several data mining projects involving crowdsource research and also development of web spiders. He is the author of several white papers on the design and deployment of low bandwidth prolog based semantical web scraping bots as well as analysis of metamorphic computer viruses through a case study on Zmist.
His current projects focus on evangelism and education for Bitcoin and fully homomorphic encryption schemes.
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
The blockchain is a distributed ledger technology that underlies cryptocurrencies like Bitcoin and platforms like Ethereum. It provides a way to record and transfer data that is transparent, safe, auditable, and resistant to outages. The blockchain has the ability to make the organizations that use it transparent, democratic, decentralized, efficient, and secure. It's a technology that holds a lot of promise for the future, and it is already disrupting many industries.
