Blockchain Fundamentals
Master the core concepts that power all blockchain networks. These principles apply whether you're working with Bitcoin, Ethereum, Solana, or any other blockchain.
Core Concepts
Cryptographic Hashing
The mathematical foundation that makes blockchains tamper-proof. Learn how SHA-256, Keccak, and other hash functions secure different networks.
Digital Signatures
How blockchain networks verify ownership and authorize transactions without central authorities.
Consensus Mechanisms
Compare Proof of Work (Bitcoin), Proof of Stake (Ethereum 2.0), and other consensus algorithms.
Network Architecture
Distributed Networks
Understanding peer-to-peer networks, node types, and how blockchains achieve decentralization.
Block Structure
The anatomy of a block: headers, transactions, and how blocks link together across different chains.
State Management
How different blockchains track balances, smart contract state, and transaction history.
Compare Blockchain Networks
Each blockchain makes different trade-offs between speed, security, and decentralization. Understanding these differences helps you choose the right platform for your needs.
Bitcoin
- • Proof of Work
- • ~10 min blocks
- • Maximum security
- • Limited scripting
Ethereum
- • Proof of Stake
- • ~12 sec blocks
- • Smart contracts
- • EVM compatible
Solana
- • Proof of History
- • ~400ms blocks
- • High throughput
- • Rust programs
