OP Labs, the developer of the Optimism community, launched a testnet model of its fault-proof system, in response to an Oct. 3 weblog submit. As soon as it completes testing, it’s going to enable for “a extra decentralized and environment friendly Superchain,” the submit acknowledged. The brand new system is at the moment deployed to the Optimism Goerli community.
At present, OP Stack-based networks use centralized sequencers to bundle transactions and submit them to Ethereum. Customers can not submit fraud proofs to dam the sequencer if it submits incorrect knowledge, creating the potential for fraudulent transactions being confirmed if an attacker can management it. L2Beat has warned of this danger in its report on Optimism, stating, “customers have to belief block Proposer to submit right L1 state roots.”
OP Stack-based networks like Optimism and Base are supposed to be optimistic rollups — a kind of layer 2 that depends on Ethereum for its safety. In a January 2021 essay, Ethereum co-founder Vitalik Buterin argued that optimistic rollups should enable customers to submit fraud proofs to dam fraudulent withdrawals to Ethereum. In any other case, they’re not really decentralized.
In November 2022, Buterin claimed that some rollups might have “coaching 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 aim of decentralization for OP Stack networks: “The system is designed to finally allow safe bridging with out central fallback.”

As well as, it claimed the brand new system is modular, permitting every community 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 recreation protocol.” As a result of these three parts could be carried out individually, it opens up the chance for every community to “custom-build a fault proof system.”
In line with the submit, this may create extra variety within the Optimism Superchain, in the end making the entire ecosystem safer. A community might even resolve to make use of zero-knowledge proofs (ZK-proofs) as a kind of fraud-proof, the workforce acknowledged. ZK-proofs are typically utilized in zero-knowledge rollups, however not Optimistic ones.
OP Labs has been making an attempt to construct an interconnected internet of blockchain networks known as the “Superchain.” To perform this, it created the OP Stack, a set of software program instruments that can be utilized to create {custom} blockchain networks. Avail community has created “OpEVM” software program designed to perform the identical goal whereas utilizing Avail as the bottom layer as an alternative of Ethereum. Polygon’s ZK Supernets and zero-knowledge Ethereum Digital Machine Hyperchain are different examples of Superchain opponents.
