Blockchain is a technology used to store and transfer information on Internet transactions arranged into successive data blocks. A single block contains data on a specific transaction. Once a block fills up with data, another one is created, followed by another and yet another, until an entire chain is formed. A new block appears in a blockchain every 10 minutes on average. A block may be used to send information on multiple transactions that concern commercial deals, ownership titles, company shares, the sale and purchase of electrical energy and the purchase or sale of currencies, including cryptocurrencies (i.e. electronic currencies).
