Blockchain Technology

Blockchain technology is the underlying technology used by cryptocurrencies in order to validate and keep track of transactions.

Blockchain is a record of transactions linked with cryptography that is uploaded into a digital public ledger.

A blockchain consists of a group of blocks. Every group contains transaction data, a hash of the previous block and a timestamp. Its design makes it highly resistant to data modification.

Blockchain technology has no central network, offers very low transaction time and cost.
