FAQs
Q: What’s the difference between a hard fork and a soft fork?
A: A hard fork creates a permanent blockchain split (e.g., Bitcoin Cash), while a soft fork introduces backward-compatible updates.
Q: How does staking work in proof-of-stake blockchains?
A: Validators lock up tokens to secure the network and earn rewards, replacing energy-intensive mining.
Q: Why is decentralization important?
A: It eliminates single points of failure, censorship, and third-party control over data or funds.
Q: Can blockchain transactions be reversed?
A: Typically no—transactions are immutable once confirmed, though some chains offer "reversible" features.
Q: What’s the role of gas in Ethereum?
A: Gas fees pay for computation and storage, preventing spam and prioritizing transactions.
