#EthereumSecurityInitiative
1. Proof of Stake (PoS) Security
Replaced mining with validators (The Merge).
Uses slashing to penalize bad behavior.
Makes 51% attacks more expensive and harder.
2. Smart Contract Security
Audits and formal verification before deployment.
Bug bounty programs reward finding vulnerabilities.
3. Layer 2 Rollup Security
L2s (e.g., Optimism, zkSync) use fraud/validity proofs.
Funds on L2 are backed by Ethereum L1 contracts.
4. Developer Tools & Education
Tools like Slither and Mythril detect bugs.
Devs trained in secure coding via Ethereum-funded programs.
5. Community & Governance
Security upgrades proposed via EIPs.
Multiple Ethereum clients prevent software centralization.
