x/nft

Contents

Abstract

x/nft is an implementation of a Cosmos SDK module, per ADR 43, that allows you to create nft classification, create nft, transfer nft, update nft, and support various queries by integrating the module. It is fully compatible with the ERC721 specification.

Concepts

Class

x/nft module defines a struct Class to describe the common characteristics of a class of nft, under this class, you can create a variety of nft, which is equivalent to an erc721 contract for Ethereum. The design is defined in the ADR 043.

NFT

The full name of NFT is Non-Fungible Tokens. Because of the irreplaceable nature of NFT, it means that it can be used to represent unique things. The nft implemented by this module is fully compatible with Ethereum ERC721 standard.

State

Class

Class is mainly composed of id, name, symbol, description, uri, uri_hash,data where id is the unique identifier of the class, similar to the Ethereum ERC721 contract address, the others are optional.

  • Class: 0x01 | classID | -> ProtocolBuffer(Class)

NFT

NFT is mainly composed of class_id, id, uri, uri_hash and data. Among them, class_id and id are two-tuples that identify the uniqueness of nft, uri and uri_hash is optional, which identifies the off-chain storage location of the nft, and data is an Any type. Use Any chain of x/nft modules can be customized by extending this field

  • NFT: 0x02 | classID | 0x00 | nftID |-> ProtocolBuffer(NFT)

NFTOfClassByOwner

NFTOfClassByOwner is mainly to realize the function of querying all nfts using classID and owner, without other redundant functions.

  • NFTOfClassByOwner: 0x03 | owner | 0x00 | classID | 0x00 | nftID |-> 0x01

Owner

Since there is no extra field in NFT to indicate the owner of nft, an additional key-value pair is used to save the ownership of nft. With the transfer of nft, the key-value pair is updated synchronously.

  • OwnerKey: 0x04 | classID | 0x00 | nftID |-> owner

TotalSupply

TotalSupply is responsible for tracking the number of all nfts under a certain class. Mint operation is performed under the changed class, supply increases by one, burn operation, and supply decreases by one.

  • OwnerKey: 0x05 | classID |-> totalSupply

Messages

In this section we describe the processing of messages for the NFT module.

:::warning The validation of ClassID and NftID is left to the app developer.
The SDK does not provide any validation for these fields. :::

MsgSend

You can use the MsgSend message to transfer the ownership of nft. This is a function provided by the x/nft module. Of course, you can use the Transfer method to implement your own transfer logic, but you need to pay extra attention to the transfer permissions.

The message handling should fail if:

  • provided ClassID does not exist.
  • provided Id does not exist.
  • provided Sender does not the owner of nft.

Events

The nft module emits proto events defined in the Protobuf reference.

Overview

Package nft is a reverse proxy.

It translates gRPC into RESTful JSON APIs.

Functions

func RegisterInterfaces 

func RegisterInterfaces(registry types.InterfaceRegistry)

RegisterInterfaces registers the interfaces types with the interface registry.

func RegisterMsgServer 

func RegisterMsgServer(s grpc1.Server, srv MsgServer)

func RegisterQueryHandler 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer 

func RegisterQueryServer(s grpc1.Server, srv QueryServer)

func ValidateGenesis 

func ValidateGenesis(data GenesisState) error

ValidateGenesis checks that the given genesis state has no integrity issues
