Base advances to 'stage 1' rollup decentralization, introducing fault proofs and decentralized governance. 

## **What’s the Scoop?**
- **Vitalik’s Rollup Model**: Base achieves 'stage 1' in Vitalik Buterin’s decentralization framework, reducing centralized dependencies.
- **Fault Proofs Enabled**: Permissionless fault proofs allow users to challenge invalid transactions, improving security and transparency.
- **Security Council Introduced**: A decentralized security council of 10 members oversees network upgrades, requiring 75% consensus for changes.
