Blockchain uses

Even though the word blockchain wasn’t used in Satoshi Nakamoto’blockchain uses whitepaper, it has become quite the buzzword. A blockchain is a data structure that makes it possible to create a digital ledger of transactions and share it among a distributed network of computers. It uses cryptography to allow each participant on the network to manipulate the ledger in a secure way without the need for a central authority.

A blockchain is essentially a secure, distributed, and shared database. Even Bitcoin matches this definition: it is nothing more than a shared ledger of data. With Bitcoin, Satoshi Nakamoto demonstrated how a blockchain could be applied to currency. Some of the world’s wealthiest and smartest are betting big on this technology’s ability to disrupt other industries, just like Bitcoin has done with currency.
