Cryptocurrency
In short
Digital assets that use blockchain technology to record transactions securely across a network of computers. These assets rely on consensus mechanisms like proof of work or proof of stake to manage ownership and new coin creation.
In plain words
It is digital money that does not need a bank to work. Instead, a shared digital list called a blockchain keeps track of who owns what. This makes it very hard for anyone to cheat the system.
A simple example
If you send one Bitcoin to a friend, the network updates a public ledger to show you have less and they have more. No central bank needs to approve this transfer.
Why it matters
It allows people to send value globally without relying on traditional banks or governments. This can provide financial tools to people who do not have access to standard banking services.
Easy to mix up
Do not confuse cryptocurrency with digital banking, which is just seeing your traditional pounds or dollars on a screen.
