Back in late July 2024, the Base team announced they would launch fault proofs on the Sepolia testnet. Now, they're preparing to bring them to the Base mainnet.

## What’s the Scoop?
- **Major Milestone for Base:** Base continues to dominate the L2 space with one of the highest TVLs, and now, the upcoming launch of fault proofs brings the network closer to full decentralization.
- **What’s Next?** Although there’s no official announcement, it's likely the Base team is already working on “Stage 2 – No Training Wheels,” the next step toward decentralizing Base. While “Stage 1 – Limited Training Wheels” rolled out fairly quickly, fully decentralizing Base will still be a tough challenge.

## Bankless Take:
Some might overlook this upgrade, but it’s a significant achievement in the crypto space. Fault proofs enable users to challenge any claim, a feature currently only live on Arbitrum and OP Mainnet. With fault proofs, Base is proving to be ahead of the game in the optimistic rollup space.
