Celo Jello Hardfork Explained — OP Succinct Lite Live

Celo just hit a major milestone: the Jello hardfork is now live, activating OP Succinct Lite on Mainnet and making Celo the first chain to run this new OP Stack upgrade in production. It also becomes the first network to launch a fully auditable EigenDA data availability bridge, marking a big leap in security and scalability. The upgrade brings ZK-powered fault proofs, a new Rust-based EVM client integrated with Succinct’s SP1 prover, and a live challenger set—independent actors monitoring proposer behavior to challenge bad state submissions. This strengthens censorship resistance, trust guarantees, and decentralization from day one. For users and builders, this means better data availability, stronger security, and low-fee performance while keeping Celo aligned with mobile-first payments. For the OP Stack and the Superchain, it's real proof that OP tech, EigenDA, and ZK systems can run together in production — moving both ecosystems closer to higher throughput and Stage 2 readiness. Celo just upgraded its core security and scalability using OP tech — a win for both Celo and the broader Superchain. ⚠️ Not Financial Advice Crypto is volatile — always do your own research before making decisions. 🎙️ About The Optimism Show High-signal coverage of Base, OP Stack, and the Superchain — for builders, founders, and on-chain explorers who prefer clarity over hype. 🔔 Follow & Subscribe Subscribe for weekly Superchain updates, deep dives, and protocol-level insights that matter.
