6-Month Blockchain Roadmap for Diploma Holders:

Month 1 — JavaScript + Git
  ☐ JS fundamentals (variables, functions, objects)
  ☐ Async/await, fetch API
  ☐ Git basics: commit, push, branch
  ☐ Create GitHub account, push first repo

Month 2 — Blockchain Fundamentals
  ☐ What is a blockchain? (blocks, chains, nodes)
  ☐ Consensus: PoW vs PoS
  ☐ Wallets: public/private keys, MetaMask setup
  ☐ Gas fees and transactions
  ☐ Free resources: Alchemy University, CryptoZombies

Month 3 — Solidity Basics
  ☐ Solidity syntax: contracts, functions, modifiers
  ☐ Data types: uint, address, mapping
  ☐ Events and errors
  ☐ Deploy first contract on Remix (Sepolia testnet)

Month 4 — Hardhat + Testing
  ☐ Set up Hardhat project
  ☐ Write unit tests for contracts
  ☐ Deploy with scripts
  ☐ Understand gas optimization basics

Month 5 — Build Project 1 + 2
  ☐ ERC-20 token (your own cryptocurrency)
  ☐ Simple NFT contract (ERC-721)
  ☐ Deploy both to testnet
  ☐ Write README with contract addresses

Month 6 — Frontend + Portfolio
  ☐ Connect contract to simple React frontend
  ☐ Use Ethers.js for wallet interaction
  ☐ Polish GitHub profile
  ☐ Start applying to entry-level roles

// Your first smart contract (Solidity)
// Deploy this on Remix with Sepolia testnet

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.19;

contract SimpleStorage {
    uint256 private value;

    // Store a number on-chain
    function set(uint256 _value) public {
        value = _value;
    }

    // Read the stored number
    function get() public view returns (uint256) {
        return value;
    }
}

// What this teaches:
// ☐ Contract structure
// ☐ State variables
// ☐ Functions (public, view)
// ☐ Compilation and deployment

// Next step: add events, modifiers, and tests
// Then build an ERC-20 token contract

Project 1: Your Own Cryptocurrency (ERC-20)

What you build:
  A custom token with:
  ☐ Name, symbol, total supply
  ☐ Transfer function
  ☐ Approve and transferFrom (allowances)
  ☐ Events for transfers

Tech stack:
  ☐ Solidity
  ☐ OpenZeppelin contracts (ERC20 base)
  ☐ Hardhat for testing
  ☐ Sepolia testnet for deployment

What to put on GitHub:
  ☐ Contract code
  ☐ Deployment script
  ☐ Test file
  ☐ README with:
     - Contract address on Sepolia
     - Screenshot of token in MetaMask
     - How to run tests

This proves you can:
  ✅ Write production-pattern Solidity
  ✅ Test smart contracts
  ✅ Deploy to testnet

Project 2: NFT Collection (ERC-721)

What you build:
  A simple NFT collection with:
  ☐ Mint function (with price or free)
  ☐ Token URI pointing to IPFS metadata
  ☐ Max supply limit
  ☐ Withdrawal function for owner

Tech stack:
  ☐ Solidity + OpenZeppelin ERC721
  ☐ IPFS (Pinata or NFT.storage for metadata)
  ☐ Hardhat for deployment

What to put on GitHub:
  ☐ Contract code
  ☐ Metadata JSON files
  ☐ Deploy script
  ☐ README with:
     - Contract address
     - Link to view NFT on OpenSea testnet
     - Sample metadata JSON

This proves you can:
  ✅ Handle off-chain storage (IPFS)
  ✅ Understand NFT standards
  ✅ Build something visually demonstrable

Project 3: Simple dApp (Full Stack)

What you build:
  A minimal dApp that:
  ☐ Connects to MetaMask
  ☐ Reads data from your smart contract
  ☐ Writes data (sends a transaction)
  ☐ Shows transaction status

Tech stack:
  ☐ React (or plain HTML/JS)
  ☐ Ethers.js (v6)
  ☐ Your deployed ERC-20 or NFT contract
  ☐ Vercel / Netlify for hosting

What to put on GitHub:
  ☐ Frontend code
  ☐ Contract ABI
  ☐ README with:
     - Live demo link
     - Screenshot of wallet connection
     - Explanation of architecture

This proves you can:
  ✅ Connect frontend to blockchain
  ✅ Handle wallet interactions
  ✅ Ship a complete product

• Simple dApp with MetaMask integration (demo)

GitHub: github.com/yourname

I'm looking for an entry-level blockchain
developer role where I can contribute and
keep learning.

Would you be open to a quick chat?

Thanks,
