What is a blockchain and why does it matter?
A blockchain is a shared record that securely tracks crypto transactions — without a bank in the middle.
A blockchain is a public digital ledger that records every crypto transaction.
Instead of one company controlling it, the ledger is maintained by a global network of computers.
Why that matters:
- No single company controls your money
- Transactions are recorded publicly
- Records can’t be changed
This is what makes crypto decentralized. Unlike bank transfers, which rely on the bank to act as the middleman, crypto can move directly person to person.
