Base reaches Stage 1 decentralisation with permissionless fault proofs and a Security Council

Coinbase/Base

Base reached 'stage 1' on the rollup decentralisation scale: fault proofs became permissionless (anyone can challenge invalid states), and a Security Council of ten independent organisations now approves upgrades. At the time, Base held ~$11.7B in total value locked, the largest rollup.

• Permissionless fault proofs enable anyone to verify and challenge transaction states; removes reliance on single trusted proposer.
• Security Council of ten independent global entities approves upgrades; decentralizes governance.
• Aligns with Vitalik Buterin's rollup decentralization framework; stage 1 status earns Buterin's public support for L2s.
• Base is the largest rollup by value locked; stage 1 represents major decentralization milestone.
