Derived addresses are generated based on the main address through a certain algorithm, and they can be used for receiving and sending transactions while maintaining high privacy and security. By using derived addresses, users can conduct blockchain  transactions without revealing their true identities. Additionally, derived addresses can enable features such as multi-signature and witness isolation, improving the scalability and reliability of the system."}]}],"pr":"ef0e9cd2bfbcc7f73fc7b128ca0d18bfcd11ee63c8384ff200d4ac613df9132e"}
