🚀OP Labs launches testnet for a fault-proof system, aiming to boost decentralization and efficiency in the Optimism Superchain! Key points:

- New system allows users to submit fraud proofs, blocking fraudulent transactions.

- Modular design lets each network develop its own fraud prevention system.

- More diversity in Superchain = more security.

- Zero-knowledge proofs could be used as fraud-proof option.

- Competitors include Avail's OpEVM, Polygon's ZK Supernets, and Hyperchain.

Get ready for a safer, more decentralized Optimism! 💪
