To buy, store, and manage cryptocurrencies, you need something called a wallet. A crypto wallet is a program that generates two important keys: a public key and a private key. These keys are made up of unique sets of letters and numbers.
- The public key acts like your wallet’s address. It’s the destination where others can send you digital assets, and it's visible to anyone who wants to send you funds.
- The private key is your personal key to unlock your wallet. It creates a digital signature on the blockchain that confirms your right to send and receive transactions.
Protecting Your Private Key
In the world of blockchain, control over an address belongs to the person who has the private key. If you lose your private key, you lose access to your wallet—and any crypto funds in it. That’s why it's crucial to protect your private key. If someone else gains access to it, they can transfer your assets out of your wallet.
Both the public and private keys work hand in hand. The public key is needed for others to initiate a transaction with you, while the private key allows you to confirm and decrypt the transaction.
