Best known as the immutable database that runs underneath cryptocurrencies like Bitcoin and Ethereum, blockchain is poised to play a critical role in every industry imaginable as businesses seek ways to cash in on the distributed ledger technology’s promise of enabling a “trustless” consensus to validate transactions.

Smart miners need to keep electricity costs to under $0.11 per kilowatt-hour; mining with 4 GPU video cards can net you around $8.00 to $10.00 per day (depending upon the cryptocurrency you choose), or around $250-$300 per month.

Financial transactions are typically guaranteed by a trusted third party (such as PayPal) and blockchain can be used to automate that process, reducing overall costs by cutting out the middleman with autonomous smart contracts acting as trusted intermediaries between parties on the network.

A blockchain,[1][2][3] originally block chain,[4][5] is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[1][6] Each block typically contains a cryptographic hash of the previous block,[6] a timestamp and transaction data.[7] By design, a blockchain is inherently resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”.[8] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
