Build a Blockchain from Scratch in Python | DLT Implementation

Learn how blockchains work by building one from scratch in Python! This hands-on lab session covers the core concepts of Distributed Ledger Technology (DLT) — from creating blocks and SHA-256 hashing to Proof of Work mining, Merkle trees, P2P network simulation, and fork resolution. 🔹 What you'll learn: • Block class design with SHA-256 cryptographic hashing • Proof of Work implementation & mining simulation • Genesis block creation (with Bitcoin's real genesis block story) • Chain validation & tamper detection • Transaction lifecycle & mining rewards • Merkle root calculation for efficient verification • Peer-to-Peer network simulation & block propagation • Nakamoto Consensus — the longest chain rule • Fork detection & resolution • Building a blockchain explorer with Flask • Setting up Hardhat, MetaMask 💻 Tools used: Python, Hardhat, Node.js, MetaMask, Flask #Blockchain #Python #DLT #ProofOfWork #CryptographicHashing #SHA256 #MerkleTree #P2P #Hardhat #MetaMask #Web3 #BlockchainDevelopment #Cryptocurrency #DecentralizedLedger #CodingTutorial #LearnBlockchain #PythonBlockchain #BlockchainFromScratch
