Optimism network launches testnet fault-proof system in pursuit of decentralization

OP Labs, the developer of the Optimism network, launched a testnet mentation of its fault-proof system, according to an Oct. 3 blog post. Once it completes testing, it volition let for “a much decentralized and efficient Superchain,” the station stated. The caller strategy is presently deployed to the Optimism Goerli network.

Currently, OP Stack-based networks usage centralized sequencers to bundle transactions and taxable them to Ethereum. Users cannot taxable fraud proofs to artifact the sequencer if it submits incorrect data, creating the anticipation of fraudulent transactions being confirmed if an attacker tin power it. L2Beat has warned of this hazard successful its study connected Optimism, stating, “users request to spot artifact Proposer to taxable close L1 authorities roots.”

OP Stack-based networks similar Optimism and Base are intended to beryllium optimistic rollups — a benignant of furniture 2 that relies connected Ethereum for its security. In a January 2021 essay, Ethereum co-founder Vitalik Buterin argued that optimistic rollups must let users to taxable fraud proofs to artifact fraudulent withdrawals to Ethereum. Otherwise, they’re not genuinely decentralized.

In November 2022, Buterin claimed that immoderate rollups could person “training wheels” that support them temporarily centralized portion they enactment connected a fraud-proof strategy but argued that they should enactment toward decentralization.

OP Labs claims the caller fault-proof strategy volition assistance fulfill the extremity of decentralization for OP Stack networks: “The strategy is designed to yet alteration unafraid bridging without cardinal fallback.”

In addition, it claimed the caller strategy is modular, allowing each web to make its ain strategy for preventing fraud. It consists of 3 abstracted components: a fault-proof programme (FPP), a fault-proof virtual instrumentality (FPVM) and a “dispute crippled protocol.” Because these 3 components tin beryllium implemented separately, it opens up the anticipation for each web to “custom-build a responsibility impervious system.”

According to the post, this volition make much diverseness successful the Optimism Superchain, yet making the full ecosystem much secure. A web could adjacent determine to usage zero-knowledge proofs (ZK-proofs) arsenic a benignant of fraud-proof, the squad stated. ZK-proofs are mostly utilized successful zero-knowledge rollups, but not Optimistic ones.

OP Labs has been trying to physique an interconnected web of blockchain networks called the “Superchain.” To execute this, it created the OP Stack, a acceptable of bundle tools that tin beryllium utilized to make customized blockchain networks. Avail web has created “OpEVM” bundle designed to execute the aforesaid nonsubjective portion utilizing Avail arsenic the basal furniture alternatively of Ethereum. Polygon’s ZK Supernets and zero-knowledge Ethereum Virtual Machine Hyperchain are different examples of Superchain competitors.
