OP Labs, the developer of the Optimism network, launched a testnet model of its fault-proof system, in accordance with an Oct. 3 weblog put up. Once it completes testing, it would permit for “a more decentralized and efficient Superchain,” the put up acknowledged. The new system is at the moment deployed to the Optimism Goerli network.
Currently, OP Stack-based networks use centralized sequencers to bundle transactions and submit them to Ethereum. Users can not submit fraud proofs to dam the sequencer if it submits incorrect information, creating the likelihood of fraudulent transactions being confirmed if an attacker can management it. L2Beat has warned of this threat in its report on Optimism, stating, “users need to trust block Proposer to submit correct L1 state roots.”
OP Stack-based networks like Optimism and Base are supposed to be optimistic rollups — a kind of layer 2 that relies on Ethereum for its security. In a January 2021 essay, Ethereum co-founder Vitalik Buterin argued that optimistic rollups must permit customers to submit fraud proofs to dam fraudulent withdrawals to Ethereum. Otherwise, they’re not really decentralized.
In November 2022, Buterin claimed that some rollups might have “training wheels” that hold them quickly centralized whereas they work on a fraud-proof system however argued that they need to work towards decentralization.
OP Labs claims the brand new fault-proof system will assist fulfill the objective of decentralization for OP Stack networks: “The system is designed to eventually enable secure bridging without central fallback.”

In addition, it claimed the brand new system is modular, permitting every network to develop its personal system for stopping fraud. It consists of three separate parts: a fault-proof program (FPP), a fault-proof digital machine (FPVM) and a “dispute game protocol.” Because these three parts could be carried out individually, it opens up the likelihood for every network to “custom-build a fault proof system.”
According to the put up, it will create extra range in the Optimism Superchain, finally making the entire ecosystem safer. A network might even determine to make use of zero-knowledge proofs (ZK-proofs) as a kind of fraud-proof, the workforce acknowledged. ZK-proofs are usually utilized in zero-knowledge rollups, however not Optimistic ones.
OP Labs has been making an attempt to construct an interconnected net of blockchain networks called the “Superchain.” To accomplish this, it created the OP Stack, a set of software program instruments that can be utilized to create customized blockchain networks. Avail network has created “OpEVM” software program designed to perform the identical goal whereas utilizing Avail as the bottom layer as a substitute of Ethereum. Polygon’s ZK Supernets and zero-knowledge Ethereum Virtual Machine Hyperchain are different examples of Superchain opponents.
