oNFT - OmniFlix Non-Fungible Token

The oNFT module is a part of the OmniFlix Network and enables the classification and tokenization of assets.

• Assets can be classified under denoms (aka collections across various ecosystems)
• Tokenize media assets by minting NFTs

Note: This module used the irismod/nft repository for initial development and has been modified to meet the requirements of the OmniFlix Network.

Denom / Collection

A denom is a collection of NFTs. It is a unique identifier for a collection of NFTs.

message Denom {
  option (gogoproto.equal) = true;

  string id                = 1;
  string symbol            = 2;
  string name              = 3;
  string schema            = 4;
  string creator           = 5;
  string description       = 6;
  string preview_uri       = 7 [
    (gogoproto.moretags)   = "yaml:\"preview_uri\"",
    (gogoproto.customname) = "PreviewURI"
  ];
}

oNFT

oNFT is a non-fungible token that represents a unique asset

message ONFT {
  option (gogoproto.equal)                = true;

  string                    id            = 1;
  Metadata                  metadata      = 2 [(gogoproto.nullable) = false];
  string                    data          = 3;
  string                    owner         = 4;
  bool                      transferable  = 5;
  bool                      extensible    = 6;
  google.protobuf.Timestamp created_at    = 7 [
    (gogoproto.nullable) = false,
    (gogoproto.stdtime)  = true,
    (gogoproto.moretags) = "yaml:\"created_at\""
  ];
  bool                      nsfw          = 8;
  string                    royalty_share = 9 [
    (gogoproto.nullable)   = false,
    (gogoproto.moretags)   = "yaml:\"royalty_share\"",
    (gogoproto.customtype) = "github.com/cosmos/cosmos-sdk/types.Dec"
  ];
}

message Metadata {
  option (gogoproto.equal) = true;

  string name              = 1 [(gogoproto.moretags) = "yaml:\"name\""];
  string description       = 2 [(gogoproto.moretags) = "yaml:\"description\""];
  string media_uri         = 3 [
    (gogoproto.moretags)   = "yaml:\"media_uri\"",
    (gogoproto.customname) = "MediaURI"
  ];
  string preview_uri       = 4 [
    (gogoproto.moretags)   = "yaml:\"preview_uri\"",
    (gogoproto.customname) = "PreviewURI"
  ];
}

State

The state of the module is expressed by following fields

1. Collection: an object contains denom & list of NFTs
2. Params: an object contains the parameters of the module

message GenesisState {
  repeated Collection collections = 1 [(gogoproto.nullable) = false];
  Params params = 2 [(gogoproto.nullable) = false];
}

message Collection {
  option (gogoproto.equal) = true;

  Denom         denom      = 1 [(gogoproto.nullable) = false];
  repeated ONFT onfts      = 2 [(gogoproto.customname) = "ONFTs", (gogoproto.nullable) = false];
}

// module params
message Params {
  cosmos.base.v1beta1.Coin     denom_creation_fee = 1 [
    (gogoproto.moretags) = "yaml:\"denom_creation_fee\"",
    (gogoproto.customtype) = "github.com/cosmos/cosmos-sdk/types.Coin",
    (gogoproto.nullable) = false
  ];
}

The module supports the following capabilities for classification and tokenization:

• Creation of collections (denoms)
• Minting of NFTs
• Transferring of NFTs
• Burning of NFTs

Various queries are available to get details about denoms/collections, NFTs, and related metadata including but not limited to ownership. Click here to try them out by interacting with the chain.

1) Create Denom (Collection)

To create an oNFT denom, you will need to use the "onftd tx onft create" command with the following args and flags:

args: symbol: denom symbol

flags: name : name of denom/collection description: description for the denom preview-uri: display picture url for denom schema: json schema for additional properties creation-fee: denom creation-fee to create denom

Example:

    onftd tx onft create <symbol> \
     --name=<name> \
     --description=<description> \
     --preview-uri=<preview-uri> \
     --schema=<schema> \
     --creation-fee=<creation-fee> \
     --chain-id=<chain-id> \
     --fees=<fee> \
     --from=<key-name>

2) Mint an oNFT

To create an oNFT, you will need to use the "onftd tx onft mint" command with the following flags:

denom-id: the ID of the collection in which you want to mint the NFT name: the name of the NFT description: a description of the NFT media-uri: the IPFS URI of the NFT preview-uri: the preview URI of the NFT data: any additional properties for the NFT (optional) recipient: the recipient of the NFT (optional, default is the minter of the NFT) non-transferable: flag to mint a non-transferable NFT (optional, default is false) inextensible: flag to mint an inextensible NFT (optional, default is false) nsfw: flag to mark the NFT as not safe for work (optional, default is false) royalty-share: the royalty share for the NFT (optional, default is 0.00)

Example:

onftd tx onft mint <denom-id> \
--name="NFT name" \
--description="NFT description" \
--media-uri="https://ipfs.io/ipfs/...." \
--preview-uri="https://ipfs.io/ipfs/...." \
--data="{}" \
--recipient="" \
--chain-id=<chain-id> \
--fees=<fee> \
--from=<key-name> 

Optional flags:

--non-transferable 
--inextensible 
--nsfw 

For a royalty share:

--royalty-share="0.05" # 5%

3) Transfer an oNFT

To transfer an oNFT, you will need to use the "onftd tx onft transfer" command with the following flags:

recipient: the recipient's account address denom-id: the ID of the collection in which the NFT is located onft-id: the ID of the NFT to be transferred chain-id: the ID of the blockchain where the transaction will be made (required) fees: the transaction fees (required) from: the name of the key to sign the transaction with (required)

Example:

onftd tx onft transfer <recipient> <denom-id> <onft-id> \
--chain-id=<chain-id> \
--fees=<fee> \
--from=<key-name>

4) Burn an oNFT

To burn an oNFT, you will need to use the "onftd tx onft burn" command with the following flags:

denom-id: the ID of the collection in which the NFT is located onft-id: the ID of the NFT to be burned chain-id: the ID of the blockchain where the transaction will be made (required) fees: the transaction fees (required) from: the name of the key to sign the transaction with (required)

Example:

onftd tx onft burn <denom-id> <onft-id> \
--chain-id=<chain-id> \
--fees=<fee> \
--from=<key-name>
