Why is this related to crypto?
Instead of trusting one entity, such as a bank, to control our money, decentralized systems maintain a permanent record that can verify our operations.
Operations
The details of your operations are saved in a block.
New blocks generation
New operations generate new blocks. This requires computing power to solve complex mathematical problems, so some operations can take time.
Blockchains benefits!
Once the block is generated, your operation benefits from blockchain transparency and security.
