What is the importance of private key?
The public and private key system is one of the innovations in cryptography that makes digital currencies possible and secure. Here's how they work.
- Cryptocurrencies like Bitcoin and Ethereum are decentralized — meaning there is no bank or any other institution in the middle holding your digital currency. Instead, your cryptocurrency is distributed across a network of computers through a technology called blockchain. A characteristic of encrypted blockchains is that they are open: all public keys and transaction information are available for anyone to view.
- Through some complex math, your public key is actually generated from your private key, which makes them a pair. When you use your public key to make a transaction, you verify that it is really you by using your private key.
- Although everything is public, it's also anonymous -- you don't need to give your name or address or any other information to use cryptocurrency.
- Take bitcoin for example. Even though any curious observer can see when bitcoins are bought, sold or used, only the holder of the private key can make those transactions.
