Transaction (Tx)
| A transaction refers to the process where users exchange cryptocurrencies on a blockchain. Transactions are how cryptocurrencies are moved from one person to another and how new units of a cryptocurrency are created. Transactions are completed through the use of a wallet, which stores the user's private and public keys. The public key is what is used to create a cryptocurrency address, which is where the user's funds are stored. The private key is what is used to sign off on a transaction, which verifies that the user is the owner of the funds being sent. When a user wants to send cryptocurrency to another user, they create a transaction. This transaction is then broadcast to the network of computers that make up the blockchain. These computers, called nodes, then verify the transaction. Once a transaction is verified, it is added to the blockchain as a new block. The process of verification is important because it ensures that no one can spend the same cryptocurrency twice. This is known as the double-spending problem and is one of the main issues that cryptocurrencies aim to solve. Once a transaction is added to the blockchain, it is permanent and cannot be reversed. This is why it is important to make sure that you are sending the correct amount of cryptocurrency to the correct address. If you make a mistake, there is no way to get your funds back. Transactions are an important part of how cryptocurrencies work and are one of the main reasons why they are so popular. They are fast, secure, and irreversible, which makes them perfect for online payments. |
