Public and Private Keys

In blockchain technology, public and private keys play a very important role in securing transactions and ensuring the safety of user data. But what are they exactly? How do they work? And why do they matter?

We will start by explaining what public and private keys are and how they differ from each other. Then we will discuss how they are used to secure transactions on the blockchain. Finally, we will give some examples of how public and private keys are being used in real-life applications today. We will end with a discussion of the future of blockchain technology and the role that public and private keys will play in its development.

Some definitions for better understanding:

Cryptocurrency Wallet: A digital or physical container that stores your public and private keys.

Public Key: The "address" that you give to people when you want them to be able to send you cryptocurrency.

Private Key: The key that allows you to access your cryptocurrency. It is important to keep this key safe and secure, as it gives anyone who has it access to your funds.

Transaction: A transfer of cryptocurrency from one Wallet to another. In order for a transaction to be completed, the sender needs the receiver's public key.

How does this all work together?

In order for someone to send you cryptocurrency, they need your public key. Think of it as your cryptocurrency address. Just like your email address, you can give it to anyone who wants to send you an email - and they can do so without knowing your private key.

Your private key is what allows you to access your cryptocurrency. This is what you use when you want to send cryptocurrency to someone else. When you make a transaction, you use your private key to sign it. This proves that the transaction came from you and that it hasn't been tampered with.

Why are these important?

Interacting with the blockchain requires knowledge of how to use a crypto wallet and how to manage your keys. It is extremely important to keep your private keys safe and use them for signing transactions. Remember any interaction with any smart contract is a data transaction and requires a signature for execution.  Due to this, we highly recommend checking what you are signing before you accept the data transaction.
