Blockchain Technology

A blockchain is made of blocks, each block contains a list of transactions. When a block is fully utilized with transactions, it is added to the chain in a linear, sequential order. Every block contains a separately identifiable code called a hash, that contains the hash of the previous block, granting a secure and traceable chain of information.

Mining and Validation

In cryptocurrency like Bitcoin, mining is the process of validating transactions and adding them to the blockchain. Miners use powerful computers to solve complex mathematical problems, which validate the transactions. Once a problem is solved, the miner is rewarded with new cryptocurrency tokens. This process is known as Proof of Work (PoW).

There are other way of validation as well, such as Proof of Stake (PoS), where validator choses based on the number of coins they hold and are willing to “stake” as collateral. PoS is considered more energy-efficient than PoW.
