Blockchain FAQ
What is blockchain in simple terms?
Blockchain is a tamper-resistant ledger shared across many nodes. Transactions are verified, grouped into blocks, and linked cryptographically so records remain transparent and hard to alter.
What is the difference between blockchain and cryptocurrency?
Blockchain is the underlying data infrastructure. Cryptocurrency is one use case of blockchain—digital assets transferred and secured by the network.
Why are smart contracts important?
Smart contracts are self-executing programs on blockchain networks. They automate agreements, enable DeFi protocols, and reduce reliance on centralized intermediaries.
