Blockchain, understanding how it works while creating one

Are you curious about cryptocurrency and want to understand how it really works? Whether you're a crypto beginner or a daily user, you likely have questions about the underlying technology. This course dives deep into the mechanics of blockchain technology, demystifying the complexities behind Bitcoin and other cryptocurrencies.

We'll explore fundamental concepts like:

• Understanding Blocks & the Blockchain: Learn what makes up a block on the blockchain and how these blocks are linked together to form a secure and transparent record.
• Blockchain Validation: Discover how blocks are validated and added to the blockchain, ensuring the integrity of the network.
• Cryptocurrency Wallets: Get a clear understanding of private keys and public keys and how they function in cryptocurrency wallets.
• Transaction Security: Learn how wallets sign and validate transactions using cryptographic principles.
• Decentralized Systems: Explore the concept of a decentralized system and why it's crucial to cryptocurrency.
• SHA256 Explained: Understand the role of SHA256 in Bitcoin and its significance in blockchain security.
• Proof of Work: Delve into the proof of work consensus mechanism and its impact on blockchain networks.

Through hands-on learning, you'll build a functional sample blockchain using JavaScript and React. We'll create each component step-by-step, including:

• SHA256 Hashers: Implement the core cryptographic function.
• Blocks: Understand the structure and data within each block.
• Blockchain: Assemble the blocks into a chain.
• Decentralized Blockchains: Explore the principles of decentralized networks.
• Transactions: Learn how transactions are created and recorded.
• Wallet Sign and Validate Transactions: Implement the transaction signing process.
• Signed Transactions: Understand the final stage of transaction creation.

Each class builds upon the previous one, progressively expanding your knowledge of blockchain technology. This course isn't about building a full-scale blockchain network; it's about gaining a practical understanding of how each part works. It's perfect for anyone wanting to gain a solid foundation in the inner workings of cryptocurrency and blockchain.
