Learn more about Blockchain

Blockchain upends traditional economic models by taking regulatory power away from centralized banks, and putting it in the hands of individual owners, where self-interest and a peer-to-peer network of “blocks” ensures security. The proliferation of cryptocurrencies has made blockchain a revolutionary new concept.

Frequently asked questions
A blockchain is a certain kind of database, and like all databases, it is a collection of structured information. However, a blockchain stores information in blocks, which are chained together. Every piece of new data that comes into the blockchain gets put into a new block. These blocks get filled up with data, and after a block is filled, it is chained to the block that came before it. In this way, data is chained in chronological order. In the context of cryptocurrencies, blockchains are used as ledgers that keep track of financial transactions. They are also used to mine new cryptocurrencies. Nodes, which are computers run by individuals or organizations, solve mathematical puzzles, and when they are verified as accurate and legitimate, they get added to the blockchain. With bitcoin, for instance, the blockchain generates about 12.5 new bitcoins every 10 minutes.
