Let's Revisit How Blockchain Actually Works
Hash functions, blocks, chains, mining, wallets, and transactions — you've learned all 6 building blocks of blockchain!
🔐
Hash Functions
One-way functions that turn any data into a fixed-length unique code
📦
Block Structure
Boxes holding transaction records — made of headers, transactions, and hashes
⛓️
Chain Linking
Each block contains the previous block's hash, linking them like a chain
⛏️
Mining
The Proof-of-Work process of changing the nonce to find a valid hash
👛
Wallets & Addresses
Tools for managing coins safely using private and public keys
💳
Transactions
Records of sending and receiving coins, and the UTXO model
