OIP-7 is designed to optimize and improve IPFS to adapt to the blockchain environment, thereby enhancing the efficiency of data storage and transmission. By canceling block height and timestamp, OIP-7 makes the storage and access of data more flexible in the blockchain network, reduces the coupling  degree of data, and enhances the independence of data. Meanwhile, this also helps to reduce the congestion of the blockchain network and improve system performance."}]}],"pr":"cdabcff7d9a6e2fe7323de3accb2ab50c8a7618828b798e3519747e072305ca5"}
