Wallets store public and private keys for cryptocurrency transactions; passwords become a hashed account ID, the private key stays secret, and the public key enables payments via sha 2256.
Learn how to initialize a blockchain database, define the blocks data model, validate and organize block data, and seed a genesis block for a functional blockchain.
Learn to run a blockchain app, set up the blockchain service, generate the genesis block, and create APIs to fetch blocks by hash, index, and last block using Next.js.
Build a key pairs system for wallets by generating secret and public keys via elliptic curves, using password-based key derivation and organizing key pairs in a wallet array.
Explore linking a password hash to a wallet's public/private key pairs by generating addresses, validating the wallet password via headers, and exposing post APIs to create and manage keys.
Verify blockchain integrity by implementing a chain check function that validates genesis block, indices, hashes, difficulty, and transactions, including balance and double spending checks across nodes.
Test and debug blockchain APIs, mine blocks, manage wallets and transactions, and validate blocks across a multi-node network using Node.js and Solidity concepts.
Explore decentralized applications on blockchain, and compare public, private, permissioned, and hybrid cryptocurrencies with real projects like Ripple, XRP, and Binance.
Welcome to the exciting world of blockchain! In this comprehensive course, you'll delve into the fascinating theory and programming behind one of the most revolutionary technologies of our time. Follow this course if your dream job is to get into companies like FACEBOOK, DISNEY, AMAZON, GOLDMAN SACHS which are early adopters of Blockchain Technology.
I have a decade of experience in Software development and I will guide you through the intricacies of blockchain, from its origins and underlying concepts to its practical applications and potential future developments.
