Free learning resources have democratized access to blockchain knowledge, allowing anyone with an internet connection to start their journey, regardless of their financial resources.
Chapter 1: Understanding Blockchain Fundamentals
Before diving into development or specialized applications, it’s crucial to grasp the basics of blockchain. This includes understanding decentralized ledgers, nodes, blocks, consensus mechanisms, and the difference between public and private blockchains.
Key Concepts in Blockchain
- Decentralized Ledger Technology (DLT): Blockchain stores data across multiple nodes in a network, ensuring no single point of failure.
- Blocks and Chains: Transactions are grouped into blocks, which are linked chronologically to form a chain.
- Consensus Mechanisms: Methods like Proof of Work (PoW) and Proof of Stake (PoS) validate transactions securely.
- Smart Contracts: Self-executing contracts with predefined rules coded on a blockchain.
- Tokens and Cryptocurrencies: Digital assets that represent value or utility on blockchain platforms.
