Multiplexing refers to the process of combining multiple data streams into a single signal for transmission. In the case of blockchain and digital currencies, it allows for improved efficiency and scalability.By using multiplexing techniques, multiple transactions can be bundled and processed together. This reduces the number of individual transactions that need to be recorded on the blockchain. The result is quicker processing times and lower fees, as fewer resources are used to verify each transaction.Multiplexing can also apply to the use of various sidechains or layers, where multiple types of transactions or smart contracts are handled simultaneously without congesting the main blockchain. This approach allows for greater flexibility and enables decentralized applications to scale more effectively.Overall, multiplexing helps to enhance the performance of blockchain networks, making them more adaptable to higher volumes of user activity while maintaining security and reliability.
