NFT Demo

This is a NFT Blockchain application created using Version 5 of lisk-sdk.

This demonstrates On-Chain and Off-Chain architecture of lisk-sdk. We will be building an NFT Token to cover up following requirements.

• A blockchain app which have support for.
  • NFT Token
    • It have an initial value
    • It have a purchase margin for auto purchase
    • It have only one owner at a time
    • Purchase margin can be set to zero meant non-purchasable
    • Anyone can create a non-fungible token if he has enough balance
    • Owner can transfer token to someone without any profit
    • Anyone can purchase a NFT if satisfy given purchase margin
• List of available Non-Fungible Tokens should be accessible

Install dependencies

cd blockchain_app && npm i --registry https://npm.lisk.io
cd frontend_app && npm i --registry https://npm.lisk.io

Start node

cd blockchain_app; node index.js

Start frontend

cd frontend_app; npm start

Test transactions

Follow these steps to test it:

1. In the UI from speed dial, click on first option to get some random account.
2. Copy the address and passphrase to somewhere else.
3. Now choose second option from speed dial and transfer funds to that account. You can use genesis account passphrase for it.
4. Repeat the above steps to create another account.
5. Now choose third option from speed dial to create an NFT Token.
6. Provide initial value, purchase margin, fee and the passphrase of first account to sign the transaction.
7. Once that is done and you refresh the page, you will see an NFT token on the home page.
8. Later you can click on the purchase button of the token test the purchase transaction.

Caveat

1. Note the frontend app is not auto-refreshed right now. Once you notice the block height change you have to refresh it manually.
2. The frontend app is not keeping track of account nonce, so try to sending one transaction from one account in a block.
3. The NFT token transfer transaction is not yet implemented in frontend, feel free to contribute.
