Optimistic Network Launches Testnet Fault-Proof System to Pursue Decentralization
OP Labs, the developer of the Optimism network, launched a testnet version of its bug-proofing system, in an October 3rd blog post. Once it completes testing, it will “allow for a more decentralized and efficient superchain,” he wrote. The new system is currently being rolled out to the Optimism Goerli network.
Currently, OP Stack-based networks use a centralized order to process transactions and submit them to Ethereum. Users cannot provide evidence of fraud to block followers if they provide false information, which creates the possibility of fraudulent transactions being verified if an attacker gains control. L2Beat warned of this risk in its report on Optimism, saying, “Users should trust BlockProposer to provide accurate L1 state routing.”
Networks based on the OP Stack, such as Optimism and Base, are intended to be Optimistic wrappers – a type of Layer 2 that relies on Ethereum for its security. In the year In a January 2021 article, Ethereum founder Vitalik Buterin argued that optimistic summaries should allow users to submit proof of fraud to block fraudulent transactions into Ethereum. Otherwise, they are not properly decentralized.
In the year In November 2022, Buterin argued that some scrolls could have “training wheels” that would keep them temporarily centralized while working on anti-fraud systems, but should work toward decentralization.
OP Labs says the new fault-tolerant system will help achieve the decentralization goal for OP Stack networks: “The system is designed to eventually enable a reliable bridge without central failure.”

He also said that the new system is a module that allows each network to develop its own system to prevent fraud. It consists of three distinct components: Fault-Preventing Program (FPP), Fault-Proof Virtual Machine (FPVM), and the “Argument Game Protocol”. Since these three components can be implemented independently, it opens up the possibility of “customizing the error proofing system” for each network.
According to the post, this will make more difference in the Optimism Superchain, ultimately making the entire ecosystem more secure. A network may decide to use zero-knowledge proofs (ZK-proofs) as fraud-proof, the team explained. ZK-proofs are generally used in zero-knowledge scrolls, but they are not optimistic ones.
OP Labs is trying to build a “superchain” of interconnected blockchain networks. To achieve this, he created the OP Stack, a set of software tools used to create custom blockchain networks. Avail Network has created “OpEVM” software designed to achieve the same goal while using Avail as the base layer instead of Ethereum. Polygon ZK Supernets and Zero Knowledge Ethereum Virtual Machine Hyperchain are other examples of superchain competitors.
