Blockchain technology is a system that allows data to be stored across multiple computers. It works like a public ledger that is shared across a network of computers. 

Key Features of Blockchain

• Decentralisation: Blockchain is spread across many computers. This reduces the risk of data tampering.
• Transparency: All transactions are open to everyone on the network, which helps build trust among users.
• Security: Once information is added, it cannot be changed without consensus from the network.

How Does Blockchain Work?

Here’s how blockchain transactions work:

1. Initiation: A user initiates a transaction request.
2. Verification: Network participants, known as nodes, verify the transaction.
3. Block Formation: Verified transactions are combined into a block.
4. Chain Integration: The new block is added to the existing blockchain.
5. Completion: The transaction is finalised and permanently recorded.
