What is a Hard Fork? (In Blockchains)
Imagine a road where everyone agrees on the direction…
until they don’t.

A hard fork is when a blockchain changes its rules in a way that is not backward compatible.

[Olorunfemi Tayo @Highzick3]

Famous examples:
Ethereum and Ethereum Classic
Bitcoin and Bitcoin Cash
Hard forks remind us of one thing:
Blockchains are code but people decide the rules.

So in essence, Blockchain security isn’t just about smart contracts.
It’s about:
- Economics
- Networking
- Incentives
- Human mistakes
And that’s why learning the fundamentals matters.

[Olorunfemi Tayo @Highzick3]

Why Blockchains Break.

Blokchains failures do not stem primarily from hacks but from vulnerabilities baked into the system itself.

Examples:
1. Sybil Attacks & Network Resistance
Imagine a town where one person can create 10,000 fake citizens.
They vote.
They agree with themselves.
They dominate decisions.
That’s a Sybil attack.

[Olorunfemi Tayo @Highzick3]

5. Replay Attacks
A valid transaction on one chain gets replayed on another.
- Same signature.
- Different context.
- Same loss.
This is why chain IDs and replay protection matter.
