Cryptocurrency exchanges are saved via blockchain.
Essentially, a blockchain is a collection of records stored electronically.
Blocks that make up a blockchain are what contain valuable information.
When one block reaches its storage limit, it links to a new block in a “chain.”
No blockchain exists in a singular place, however.
Because cryptocurrency is decentralized, transaction records are not stored in a bank or with the government as a typical money exchange would be.
To access one’s cryptocurrencies, a crypto wallet can come into play.
A crypto wallet keeps one’s private keys – a term essentially meaning password – accessible and safe.
