Telegram Bots and Mini-Apps Developer with web3 Salary in 2024

Where is web3 used?

Decentralized Finance (DeFi)

• Imagine tossing your bank into a salad spinner and centrifuging it into a million digital pieces. That's DeFi, where blockchain gives your money a jetpack and a license to go nuts sans banks.

NFT Marketplaces

• Think of NFTs as digital snowflakes, each uniquely owned by a cyber-flaunter. Web3 platforms let you trade these like Pokemon cards on the blockchain playground.

Decentralized Autonomous Organizations (DAOs)

• DAOs are like hives run by bees with spreadsheets. Members manage projects via group chat but with more blockchain and less emoji drama.

Gaming Multiverses

• Gamers, don your virtual capes! Web3 transforms games into parallel income universes where you slay dragons for loot that pays your real rent!

Centralized Cloud Services

Centralized cloud services are managed platforms provided by companies like AWS, GCP, and Azure, offering robust infrastructure and platform services.

// AWS SDK for JavaScript example to list S3 buckets
const { S3 } = require('@aws-sdk/client-s3');
const s3 = new S3();
async function listBuckets() {
  const buckets = await s3.listBuckets({});
  console.log(buckets);
}
listBuckets();

• High reliability and uptime


• Deep feature set with managed services


• Extensive global infrastructure


• Vendor lock-in potential


• Privacy concerns with centralized control


• Cost can escalate with usage

Peer-to-Peer Networks

A decentralized network allowing direct data exchange between users without a central server. Examples include BitTorrent and IPFS (InterPlanetary File System).

// Example of adding a file to IPFS
const ipfsClient = require('ipfs-http-client');
const ipfs = ipfsClient('http://localhost:5001');
async function addFile() {
  const { path } = await ipfs.add('Hello World');
  console.log(`File added at path: ${path}`);
}
addFile();

• Resilient to censorship and outages


• Direct data transfer reduces latency


• Community-driven and open-source


• Lesser consistency and data speeds


• Scalability can be an issue


• Complexity in management and error handling

Private Blockchains

Permissioned blockchain networks like Hyperledger or Corda target business uses, providing a controlled environment for collaboration.

// Example of a chaincode function in Hyperledger Fabric
async function initLedger(ctx) {
  console.info('Instantiating ledger');
  const assets = [{ ID: 'asset1', owner: 'User1', value: '100' }];
  for (const asset of assets) {
    await ctx.stub.putState(asset.ID, Buffer.from(JSON.stringify(asset)));
  }
}

• Enhanced privacy and security controls


• Customizable to enterprise needs


• Streamlined governance processes


• Reduced transparency compared to public chains


• Network effect is limited to participants


• Can be costly to develop and maintain

Quick Facts about web3

Who spawned the Web3 web? It was Gavin Wood, not some cyberspace wizard!

Picture this: it's 2014, and this brainiac Gavin Wood thinks the internet's a bit too Google-y. He dreams up Web3, a plot twist where the users, not the tech overlords, pull the strings. Ding, ding, ding! The decentralization bell rings, and suddenly your data's your buddy, not a cash cow for mega-corporations.

Blockchain Bonanza

Gavin's gang didn't just decide to shake things up for funsies. They brought blockchain into the mix, making trust issues online kinda passé. No more middleman malarkey; Web3's got smart contracts doing deals straight up, no shifty handshakes. Just picture your computer codes pinky swearing!

// Solidity smart contract snippet - pinky swear in code
contract PinkySwear {
    function promise(string memory secretHandshake) public pure returns (string memory) {
        return string(abi.encodePacked("I pinky swear to ", secretHandshake));
    }
}

Ether-volution with Ethereum

So where's the playground for all this decentralized dazzle? Enter Ethereum, stage left, in 2015. It's not just a digital coin toss; it's a whole theatre for decentralized apps (dApps) to perform. Think of Ethereum as a Swiss Army knife, but instead of little scissors and a toothpick, you get your very own dApp toolkit!

// Example of a simple Ethereum dApp
pragma solidity ^0.8.0;

contract HelloWorld {
    string public greet = "Hello, Ethereum World!";
}

Top 10 web3 Related Tech

1. 
   

   Solidity

   
   

   
   Take a stroll through the blockchain park and you’ll bump into Solidity, the rockstar of smart contract programming. It’s like JavaScript’s distant cousin who got super into cryptoeconomics. If you whisper the right hexadecimal spells into its ear, you can get Ethereum to do your bidding.
   

   
   function helloWorld() public pure returns (string memory) {
       return "Hello, blockchain!";
   }
               

   
   
   
   


2. 
   

   Ethereum Virtual Machine (EVM)

   
   

   
   The grand theater where Solidity’s plays are performed. It’s kind of big deal in the web3 realm; think of it as the JavaScript engine of the blockchain. It’s meticulous, a bit of a perfectionist, and absolutely adores executing those snazzy smart contracts.
   

   
   


3. 
   

   Web3.js / Ethers.js

   
   

   
   These JavaScript libraries are like the Swiss Army knives for Ethereum-blockchain interactions. Web3.js walks into a bar, and suddenly, your browser becomes a blockchain genius. And Ethers.js? It's more like the hipster barista - slightly more modern, with a few extra garnishes.
   

   
   


4. 
   

   IPFS

   
   

   
   Imagine if the web was a giant, decentralized game of pass-the-parcel with data. IPFS makes it possible to store and share files across a distributed network of computers. It's like Airbnb for your digital stuff, but instead of renting out your spare room, you're sharing your spare hard drive space.
   

   
   


5. 
   

   Truffle Suite

   
   

   
   This is the chocolate box toolkit of the Ethereum world. Developing, testing, and deploying your decentralized apps (DApps) can be as delightful as snacking on truffles, thanks to this suite. It includes Truffle, Ganache, and Drizzle – it’s not a dessert menu, I promise.
   

   
   truffle init
   truffle compile
   truffle migrate

   Infura

   
   

   
   You want to connect to the Ethereum network, but you don’t want to run your own node, 'cause that's like throwing a blockchain party and only serving water. Infura is your cloud-based gateway that says, "I'll handle the node stuff, you go have fun!"
   

   
   


8. 
   

   Decentralized Autonomous Organizations (DAOs)

   
   

   
   When smart contracts and group chats have a baby, you get DAOs. They’re online clubs with their own piggy banks, and instead of having a boss, everyone votes on how to spend the money. It's like the ultimate group project where everyone actually participates.
   

   
   


9. 
   

   Non-Fungible Tokens (NFTs)

   
   

   
   These are like the shiny Pokémon cards of the digital world. Each NFT is unique and can prove ownership of digital assets. They’re all the rave for artists and creators. You can be like, "See this pixelated avatar? It’s mine. There’s not another one like it. Cool, huh?"
