A blockchain is a digital transaction of records that’s arranged in chunks of data called blocks. These blocks then link with one another through a cryptographic validation known as a hashing function. Linked together, these blocks form an unbroken chain — a blockchain.
How does Blockchain add transactions to the chain?
For a public blockchain, the decision to add a transaction to the chain is made by consensus. This means that the majority of “nodes” (or computers in the network) must agree that the transaction is valid. The people who own the computers in the network are incentivised to verify transactions through rewards.

Before adding a transaction to their block, a miner needs to check if the transaction is eligible to be executed according to the blockchain history. If the sender’s wallet balance has sufficient funds according to the existing blockchain history, the transaction is considered valid and can be added to the block.
