Normally the key of a map might be a simple address or id, but that doesn’t mean it was limited to those simple things. By understanding how smart contracts’ storage operates and using key permutation, we can achieve a more complex composite key that can be used to index our data in a more enhanced way and make our CosmWasm smart contract experience better.Key-Value StorageFirst, we need to understand how the underlying IAVL+ key-value storage operates.https://docs.cosmwasm.com/tutorials/stor...
