Blockchain
Transactions go into blocks linked in a chain. Once recorded, the history can’t be rewritten, which makes fraud practically unfeasible.
Beginner’s guide
What is cryptocurrency
Cryptocurrency is digital money that exists only on the internet and works without a central bank or government in charge. Transactions are recorded on a public network called blockchain, which makes everything transparent and virtually impossible to forge.

Concept
Cryptocurrency in one sentence
Cryptocurrency is a way to store and transfer value that lives 100% digitally, without relying on a bank or a country.
Bitcoin was the first, created in 2009, but today there are thousands, each with its own function. What they all have in common is the blockchain: a public, distributed record that can’t be rewritten, showing who owns what.
How does a cryptocurrency work?
Three pillars explain almost everything.
Decentralization
There is no central server. Thousands of computers around the world store the same copy of the ledger and verify one another.
Cryptography
It’s the mathematical protection that ensures only the owner can move their own balance. That’s where the name "crypto" comes from.
Different from traditional money
Cryptocurrency doesn’t depend on banks or business hours: it runs on the internet, all the time.
Use cases
What is a cryptocurrency used for?
