51% Attack: A Blockchain Threat?

🌐 What is it?
A 51% attack occurs when attackers control over 50% of a blockchain’s power (Proof-of-Work) or tokens (Proof-of-Stake). This lets them:
1️⃣ Double spend coins.
2️⃣ Block transactions.
3️⃣ Disrupt networks by creating forks.

This risk applies to all blockchains, not just Bitcoin.

Who’s at Risk?
Small PoW networks like Ethereum Classic with low hash rates.
PoS blockchains where attackers control 50%+ of staked tokens.
Less decentralized systems.
Why It’s Rare
💰 High cost to control a network.
👥 Community defense through forks or rollbacks.
⚙️ Technical limits restricting attackers.

Notable Cases
Ethereum Classic (2020): Repeated 51% attacks.
Bitcoin Gold (2018): $18M stolen.
💡 Conclusion:
Small blockchains are vulnerable, but mature, decentralized networks are nearly immune to 51% attacks.
