Bitcoin’s emergence as a global digital currency has been as revolutionary as it has been erratic. But while fledgling investors obsess over every fluctuation in the cryptocurrency market, nation-states are more interested in the underlying blockchain technology and its ability to revolutionize how business is done on the internet and beyond. VICEs Michael Moynihan travels to Russia with Vitalik Buterin, inventor of the ethereum blockchain, to get a front-row seat to the geopolitical tug of war over Internet 3.0.

Blockchain explained. Shai Rubin, CTO of Citi Innovation Lab, explains in an easy and simple way the basics of blockchain.

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 Bitcoins 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 its 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 networks algorithm ensures that each transaction is unique.
