In cryptocurrencies, a transaction refers to the transfer of digital assets between two parties over the blockchain network. Transactions can involve the transfer of cryptocurrencies, such as Bitcoin or Ethereum, or the transfer of other digital assets, such as tokens.
Each transaction in a cryptocurrency network contains specific information, including:
- Sender’s public key: This is the public key of the sender’s wallet address.
- Receiver’s public key: This is the public key of the receiver’s wallet address.
- Transaction amount: This is the amount of cryptocurrency being transferred.
- Transaction fee: This is a small fee paid by the sender to incentivize miners to add the transaction to the blockchain.
- Transaction ID: This is a unique identifier assigned to each transaction.
Once a transaction is initiated, it is broadcasted to the blockchain network for validation and confirmation by network nodes, also known as miners. Miners validate the transaction by verifying that the sender has sufficient funds to complete the transaction and that the transaction is legitimate.
Once a transaction is validated, it is added to a block and becomes a part of the blockchain. Transactions on the blockchain are transparent and publicly visible, but they are also secure and protected by encryption and cryptography.
Overall, transactions are a fundamental component of cryptocurrencies, allowing for secure and decentralized transfer of digital assets between parties without the need for intermediaries such as banks or financial institutions.
