Optimism's Fault Proof Goes Live on Sepolia Testnet | Layer 2 Review
Optimism's Fault Proof Goes Live on Sepolia Testnet | Layer 2 ReviewQuick Reads and Hot Links Covering the People and Projects Who Are Scaling EthereumDear Frens, Is L2 season here or is it still coming? Base is turning the L2 ecosystem on its head, surpassing $4 billion in total value locked. It has become the third-largest Layer 2 network on Ethereum and still shows no sign of slowing down. The Layer 2 space continues witnessing rapid evolution, with various solutions competing and collaborating to address Ethereum's scalability challenges and unlock new possibilities. In this week’s editorial, we dive into Optimism’s fault proof system, highlighting how it enables better security and decentralization. Now live on Sepolia, integration into mainnet is not so far away. With so much happening in the Layer 2 space, there's plenty to dive into. So stay tuned as we continue to explore and uncover the potential of the Layer 2 ecosystem.

Optimism’s Fault Proof Goes Live on Sepolia TestnetAuthor: Kornekt For about two years now, Optimism, a leading Layer 2 scaling solution, has been without a functioning proof system. The fraud proof that was initially launched with the network was later disabled due to security and compatibility concerns. Since then, users have had to trust the network and a centralized security council. This centralized approach raised significant concerns about the network's security and decentralization. The lack of a functioning proof system has brought widespread criticism of the network, with many pointing out how this creates a fundamental loophole in the system. In response to these challenges, Optimism developed a new mechanism called Fault Proofs which was rolled out on the OP Goerli testnet October last year. On the path toward the final launch on the Optimism mainnet, the fault proof was deployed on the Sepolia testnet on March 19, 2024. This marked a significant milestone for Optimism, as it provided developers and security researchers the opportunity to thoroughly test the system in a simulated environment before its final implementation. Looking Into the Fault Proof SystemOptimistic rollups work with the principle that transactions are assumed valid unless proven otherwise. If someone suspects fraud, they can submit a fraud/fault proof challenging the transaction's validity. The dispute is then resolved, ensuring the transaction's integrity before finalizing it on the mainnet. Fraud/Fault proofs are crucial for ensuring the security and trustlessness of optimistic rollups, which aim to address Ethereum's scalability challenges. They foster decentralization and security, guarantee eventual finality for valid transactions, and reduce reliance on centralized entities. Optimism's fault proof system is designed with a particular focus on modularity and permissionless validation. The system comprises three key constituents: 1. Fault Proof Program (FPP): Serving as the system’s backbone, the FPP acts as a verifier by comparing outputs generated on Optimism’s Layer 2 with the original inputs submitted on the Ethereum mainnet (L1). This ensures that computations performed on the L2 chain remain consistent with the data on the main chain. 2. Fault Proof Virtual Machine (FPVM): This component plays a pivotal role in dispute resolution. By allowing the re-execution of the code used to generate L2 outputs, the FPVM verifies the accuracy of transactions and computations on the L2. In case of disputes, this feature provides a mechanism to confirm the validity of transactions. 3. Dispute Game Protocol: Empowering users to challenge potentially fraudulent activity, the Dispute Game Protocol facilitates a collaborative process between challengers and network validators. Users can submit proofs to initiate disputes, and the protocol ensures fair resolution through a consensus mechanism. Why Launch On Testnet?Before deploying the fault proof system on the mainnet, rigorous testing on a testnet is imperative for several reasons, let's find out.
The successful deployment of the Fault Proof system on the Sepolia testnet represents a crucial step forward for Optimism in enhancing the security and decentralization of its Layer 2 scaling solution for Ethereum. Mainnet Launch ExpectationsIn an interview with CoinDesk, Karl Floersch, CEO of OP Labs, hinted that the fault proof would be live on OP mainnet later this year. While the exact launch date remains unconfirmed, post-testnet development will likely focus on further optimization, to fix bugs, improve performance, and collaborate with developers and community members to ensure seamless integration. The successful deployment of the fault proof on the Sepolia testnet marks a significant milestone for Optimism. As development progresses and preparations for the mainnet launch continue, the network moves closer to achieving its goal of providing a secure and decentralized scaling solution for Ethereum. 🔭 Project WatchArbitrumTop Projects by TVL
