A mining block is a unit of data that contains a list of transactions recorded on a blockchain. Each block comprises several key elements, such as transaction details, a timestamp, a nonce (a random number), and the hash of the previous block, forming a chain.Miners use computational power to solve complex mathematical puzzles to validate and confirm transactions. When a miner successfully solves a puzzle, they create a new block. This block is then added to the existing chain, ensuring the integrity and security of the transaction history.Upon creating a block, miners are often rewarded with newly minted coins and transaction fees from the transactions included in the block. This incentivizes miners to continue validating and securing the network.Overall, mining blocks are essential for maintaining the decentralization, transparency, and security of the entire system, enabling users to transfer assets safely and efficiently.
