How To Create Digital Assets

Examples Showing How To Create Digital Assets (NFTs) On Blockchain

STEP 1. Register A New Digital Asset Collection

NFTRegisterCollection transaction enables us to register a new type of digital asset by defining its structure. The structure is defined in the form of a standard JSONSchema (see example below). After the digital asset collection is registered we can create (mine) tokens with the help of NFTCreate transaction type. We need to define:

• asset name

• asset description

• maximum supply (optional)

• jsonSchema - structure of the digital asset

• allowedIssuers - if empty anyone can create/mine a new asset

NFT RegisterCollection Runnable Example

Initialization

import { Builders } from "@protokol/nft-base-crypto";

NFTRegisterCollection - Builder

new Builders.NFTRegisterCollectionBuilder()
    .NFTRegisterCollectionAsset({
        name: "FIFA-20-PLAYERS",
        description: "FIFA 2020 Players",
        maximumSupply: 100,
        jsonSchema: {
            properties: {
                name: {
                    type: "string",
                },
                pac: {
                    type: "number",
                },
                sho: {
                    type: "number",
                },
                pas: {
                    type: "number",
                },
                dri: {
                    type: "number",
                },
                def: {
                    type: "number",
                },
                phy: {
                    type: "number",
                },
            },
        },
    })
    .nonce("1")
    .sign("SENDER_PASSPHRASE");

STEP 2. Create New Digital Assets

We can create (mine) new digital assets from the genesis wallet (the wallet that registered the new collection in STEP 1). To create a digital asset we need to comply with the asset type - that is the collection we registered with NFTRegisterCollection transaction. We need to specify:

• collectionId

• token attributes - need to comply with the registered JSONSchema

After token is created it lives inside the genesis wallet, until it is transferred to a trading address, or to a new owner with the NFTTransfer Transaction.

NFTCreateAsset Runnable Example

NFTCreateAsset - Builder

new Builders.NFTCreateBuilder()
        .NFTCreateToken({
            collectionId: "c23b4a9e07329861422df43631d7aa72153cabcca3067941b94a69016ae8723b",
            attributes: {
                name: "Kalvin Phillips",
                pac: 90,
                sho: 89,
                pas: 60,
                dri: 57,
                def: 75,
                phy: 87,
            },
        })
        .nonce("1")
        .sign("SENDER_PASSPHRASE");

STEP 3. Transfer Digital Assets

We can transfer multiple owned digital assets. See example below for NFT Transfer Transaction Type.

NFTTransfer Runnable Example

NFTTransfer - Builder

new Builders.NFTTransferBuilder()
        .NFTTransferAsset({
            recipientId: "RECIPIENT_ADDRESS",
            nftIds: ["7373bbe5524898faec40bfcd12c6161981771f3be6426404208784831f4b0d02"],
        })
        .nonce("1")
        .sign("SENDER_PASSPHRASE");

STEP 4. Burn Digital Assets (optional)

Our NFT plugin set also enables burning capability for digital assets. This is useful with loyalty programs and expiring trading cards or gaming card functionality - where the asset is destroyed when used. Only token owners can burn/destroy a digital asset. Digital asset or usage history is still visible on the blockchain.
