What is a Hard Fork?
🔧 Hard Fork = blockchain protocol upgrade that is not backward compatible.
How it works:
• Network splits into two versions
• Requires nodes/miners to upgrade to new version
Why hard forks happen:
• Add new features
• Fix security vulnerabilities
• Resolve governance disputes
Examples:
• Bitcoin → Bitcoin Cash (BCH)
• Ethereum → Ethereum Classic (ETC)
Risks:
• Chain splits
• Community fragmentation
