Welcome to the world of blockchain technology! 🌐⛓️ This tutorial will break down the fundamental concepts that make blockchain a revolutionary innovation.
What is Blockchain?
Blockchain is a decentralized digital ledger that records transactions across many computers. Here's how it works:
- Decentralized Network: No single entity controls the entire system. Instead, it's maintained by a distributed network of nodes. 🌍
- Immutable Records: Once data is added to the blockchain, it cannot be altered or deleted. 🔒
- Cryptographic Security: Each block is secured using cryptographic hash functions. 🔐
- Smart Contracts: Self-executing contracts with the terms directly written into code. 📜
How Does Blockchain Work?
- Transaction Initiation: A user initiates a transaction, which is broadcast to the network. 📡
- Verification: Nodes verify the transaction using consensus algorithms. 👥
- Block Creation: Verified transactions are grouped into blocks. 🧱
- Block Addition: Blocks are added to the chain via cryptographic hashing. 🔗
- Finalization: The blockchain is updated, and the transaction is complete. ✅
Use Cases
