Build your own blockchain from scratch with Typescript and Node.JS

🚀 Build Your Own Blockchain from Scratch with TypeScript! 💡 Tired of only using cryptocurrencies? In this epic video series, we're diving deep to build our own complete *Blockchain Network from scratch* using *TypeScript**! You'll move beyond the hype and gain a profound understanding of the internal design that powers currencies like **Bitcoin* and **Ethereum**. This first video focuses on building the **core underlying blockchain**—the immutable digital ledger. What We'll Build & Implement: *💸 Transaction Class:* Define how value moves. Learn to implement `calculateHash()` and the crucial `signTransaction()` and `isValid()` methods using *Digital Signatures* to verify authenticity. *📦 Block Class:* Aggregate transactions and secure the ledger. Master the *Proof-of-Work (PoW)* mechanism with the `mineBlock(difficulty)` method by iteratively finding the correct `nonce`. *🔑 Wallet Class:* Manage user identity. Implement key generation using *BIP39 mnemonics* and *ECC* to create **public/private key pairs**. Learn to securely `encrypt/decryptPrivateKey` and `createTransaction()`. *⛓️ Blockchain Class (The Engine):* The heart of the network. Implement the `chain` (the ledger), `pendingTransactions`, and core logic like `minePendingTransactions()` (for mining and miner rewards) and the vital `isChainValid()` and `replaceChain()` methods for **network consensus**. 🔹 What You'll Learn: ✅ *Cryptographic Hashing (SHA-256):* The backbone of immutability. ✅ *Elliptic Curve Cryptography (ECC):* Generate keys and sign transactions. ✅ *Proof-of-Work (PoW):* Understand the mechanism that secures Bitcoin. ✅ *Digital Signatures:* Verify transaction origin and integrity. ✅ *Wallet Management:* Key generation, security, and transaction initiation. ✅ *Blockchain Consensus:* How a network agrees on a single, valid history. Practical Outcomes: A functional, hash-linked chain of blocks. Classes for secure **Transactions**, **Blocks**, and user **Wallets**. The foundational knowledge for building a complete P2P Network in the next videos! --- #blockchain #typescript #cryptocurrency #web3 #nodejs #programming #coding #crypto #P2P 💡 *Who is this for?* Developers curious about the mechanics of cryptocurrencies.
