Blockchain Verification

Verification is the process by which new transactions are added to blockchains. Transactions are added as blocks, which represent discrete units of transaction data. The authentication process involves the use of public and private encrypted digital signatures, which link transactions and corresponding digital assets to particular individuals or parties. Transactions are verified and added to blockchains through consensus mechanisms. A consensus mechanism is a complex algorithm that authenticates the validity of a transaction and renders fraudulent activity financially untenable. Miners are responsible for this process and are usually rewarded with digital currency for expending the resources necessary for verification.
