An aggregated signature combines multiple individual signatures into a single, more compact signature. This helps save space and improve efficiency, especially in applications where many signatures are required for validating transactions or messages.In a typical scenario, each participant in a network generates their own signature for a transaction. Instead of storing all these signatures separately, they can be aggregated into one. This reduces the amount of data that needs to be processed and stored.Aggregated signatures also enhance privacy because they can obscure the number of signatures involved and make it harder to trace specific individual signatures back to their owners. This technique is especially useful for scalability, allowing blockchains to handle more transactions without significantly increasing the size of the blockchain.Overall, aggregated signatures improve both the speed and efficiency of transaction verification while maintaining security and privacy. This makes them a valuable tool in the development of more scalable blockchain solutions.
