Firstly, the metadata of NFTs is compressed to save space  and improve efficiency during the transmission process. Then, these compressed metadata are stored in the index service so that users and applications can quickly search and look up. During the transmission process, the compressed metadata usually adopts secure encryption algorithms to ensure the security and integrity of the data. In addition, to achieve more efficient data storage and transmission, sharding technology and distributed ledger technology can also be adopted. Sharding technology divides the metadata into multiple fragments and stores them in different locations."}]}],"pr":"4546f509ddfb155ec6e0e9a76713030c132efda8afad0bd7073628f623cfa3c8"}
