How does Private Key work?

• Private keys work using a concept called asymmetric cryptography. Asymmetric cryptography have two keys: a public key and a private key. The public key encrypts the data, whereas the private key is used to decrypt it.
  

• In terms of cryptocurrency, the public key is your wallet address. Anyone can send a cryptocurrency to your wallet address, but only you can decrypt the transaction using your private key.
  

• While creating a cryptocurrency wallet, a random number is generated and used to create your public key and private key. The public key is made public, while the private key is kept secret.
  

• To send cryptocurrency, you need to use your private key to confirm the transaction. This proves that you’re the owner of the cryptocurrency that is being transferred. The transaction is then broadcast to the network, and it is verified by the miners.
  

• If the transaction is verified, it is added to the blockchain. The blockchain is a public ledger that records all cryptocurrency transactions. Once the transaction is added to the blockchain, it is irreversible.
