A blockchain is a type of distributed ledger technology that consists of growing list of records, called blocks, that are securely linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.
Blockchain technology can be integrated into multiple areas. The primary use of blockchains is as a distributed ledger for cryptocurrencies such as bitcoin; there were also a few other operational products that had matured from proof of concept by late 2016. As of 2016, some businesses have been testing the technology and conducting low-level implementation to gauge blockchain's effects on organizational efficiency in their back office.
Gaining prominence rapidly, blockchain technology is counted among the hot trends that businesses must keep an eye on to stay ahead. Everyone is eager to learn about this new trend as it is bringing about significant advancements and leading to new opportunities in every industry, whether it is banking, healthcare, cyber security, advertising, or finance.
