Smart Contracts Developer with NFT (non-fungible token) Salary in 2024

Where is NFT (non-fungible token) used?

Digital Art Galleries

• Gone are the days of wine and cheese at art shows! NFTs let you hoard digital Picassos in virtual galleries, where the only spilled red is pixel paint.

Exclusive Club Memberships

• Forget secret handshakes; owning a unique NFT is your VIP pass to clubs cooler than a polar bear's toenails.

Online Gaming Swag

• With NFTs, your sword in a game isn't just epic, it's one-of-a-kind. Because why just defeat dragons when you can do it in exclusive style?

Historic Tweets

• Ever wanted to own a piece of history? Now you can frame someone's 140 characters as if it's the digital Mona Lisa's smile.

NFT (non-fungible token) Alternatives

Distributed Ledgers

Similar to blockchains, distributed ledgers are databases spread across multiple sites, countries, or institutions. They do not require a central authority.

// Example: Using Hyperledger Fabric (Blockchain Framework)
const fabric = require('fabric-network');
const connection = new fabric.Network();
// Connect to ledger
connection.connect('someChannel', 'Peer1');

• Decentralization reduces the risk of centralized control and failure.


• They may not be as secure as NFTs due to varying consensus mechanisms.


• Useful for tracking assets and recording transactions.

Digital Collectibles

These are unique digital items with proof of ownership but do not necessarily use blockchain technology and may not be as securely owned as NFTs.

// Example: Digital Collectible in a Game
class Collectible {
  constructor(name, owner) {
    this.name = name;
    this.owner = owner;
  }
}
const myCollectible = new Collectible('Dragon', 'Player1');

• They provide a similar sense of ownership and collection as NFTs.


• May lack a transparent record of ownership.


• Common in online games and communities.

Hashgraph

Hashgraph is a consensus algorithm, like blockchain, that offers a way to distribute consensus without proof of work, potentially being faster and more energy-efficient than blockchains.

// Pseudo-code: Using hashgraph concept
let hashgraph = new Hashgraph();
hashgraph.addEvent('transaction', 'Alice->Bob:10');
hashgraph.gossipAboutEvents();

• Faster transaction speed compared to traditional blockchains.


• May not have the same level of adoption and thus, fewer integrations.


• Useful for creating fast, secure, and fair distributed applications.

Quick Facts about NFT (non-fungible token)

A Colorful Tale of "Token" Proportions

Behold the mighty NFT! Birthed from the tech womb in 2014, these digital unicorns are one-of-a-kind assets that can't be swapped on a whim like your regular Joe of cryptos. Created by Kevin McCoy and Anil Dash, they whipped up the first NFT named "Quantum" way before these tokens became the cool kids on the blockchain. This digital mosaic simply said, "Hello world, look at me!"

Hatching the Non-Fungible Eggs: ERC-721

Fast forward to 2017 and kaboom! A standard known as ERC-721 was proposed by William Entriken, Dieter Shirley, Jacob Evans, and Nastassia Sachs. This wasn't just a number folks, it was the Silicon blueprint—the skeleton key that unlocked the power of uniqueness in the Ethereum blockchain, setting the stage for all the CryptoKitties and pixelated punks to come. Time to breed your digital cats, folks!

pragma solidity ^0.4.20;

contract ERC721 {
  event Transfer(address indexed _from, address indexed _to, uint256 _tokenId);
  event Approval(address indexed _owner, address indexed _approved, uint256 _tokenId);

  function balanceOf(address _owner) public view returns (uint256 _balance);
  function ownerOf(uint256 _tokenId) public view returns (address _owner);
  function transfer(address _to, uint256 _tokenId) public;
  function approve(address _to, uint256 _tokenId) public;
  function takeOwnership(uint256 _tokenId) public;
}

The "Smart" Boom: Smart Contracts Galore!

And then came the "smart" part of the NFT craze. These aren't your average vending machines; they're smart contracts, people! These chunks of code live on the blockchain, making sure that when you fork over some digital dough for a pixelated masterpiece, it's yours through a transaction more secure than Fort Knox. But remember, just because it's smart, doesn't mean it understands your coffee order.

pragma solidity ^0.4.24;

contract MyNFT is ERC721 {
  // Mapping from token ID to the owner's address
  mapping(uint256 => address) private _tokenOwner;

  // Mapping from token ID to approved address
  mapping(uint256 => address) private _tokenApprovals;

  function _exists(uint256 tokenId) internal view returns (bool) {
    address owner = _tokenOwner[tokenId];
    return owner != address(0);
  }
  
  function _mint(address to, uint256 tokenId) internal virtual {
    require(to != address(0), "ERC721: mint to the zero address");
    require(!_exists(tokenId), "ERC721: token already minted");
    
    _tokenOwner[tokenId] = to;
    emit Transfer(address(0), to, tokenId);
  }
}
