What is bitcoin

Bitcoin is digital money. Physically, the currency does not exist, there are only special registries that keep track of how many bitcoins someone has and who transfers them to where. These registers are called blockchains.

It’s similar to the way cashless payments in banks are set up: when you pay with a card in a store, you don’t hand over any physical money or gold to anyone, either. It’s just somewhere in the bank register that your transaction is recorded.

Bitcoins differ from regular currency in that registries are not stored centrally in banks and payment systems, but simultaneously on all the computers that are occupied by bitcoins. Anyone can see all transactions of all bitcoins throughout history.

The registers are cryptographically protected. It is impossible to tamper with them all at once. You can’t rewrite the data in the blocks and claim that someone now has millions. Bitcoin is pretty secure in that sense. It is true that there is already an attack that allows you to pay twice with the same bitcoins, so it is impossible to say that bitcoin is absolutely secure.
