You might be familiar with spreadsheets or databases. A blockchain is somewhat similar because it is a database where information is entered and stored. But the key difference between a traditional database or spreadsheet and a blockchain is how the data is structured and accessed.
Transaction Process
Transactions follow a specific process, depending on the blockchain they are taking place on. For example, on Bitcoin’s blockchain, if you initiate a transaction using your cryptocurrency wallet — the application that provides an interface for the blockchain — it starts a sequence of events.
In Bitcoin, your transaction is sent to a memory pool, where it is stored and queued until a miner or validator picks it up. Once it is entered into a block and the block fills up with transactions, it is closed and encrypted using an encryption algorithm. Then, the mining begins.
The entire network works simultaneously, trying to “solve” the hash. Each one generates a random hash except for the “nonce,” short for number used once.
Every miner starts with a nonce of zero, which is appended to their randomly-generated hash. If that number isn’t equal to or less than the target hash, a value of one is added to the nonce, and a new block hash is generated. This continues until a miner generates a valid hash, winning the race and receiving the reward.
