The testnet launch of OP Stack’s fault proof system is preparing for zero-knowledge proofs and a more secure ecosystem.
Posted October 3, 2023 at 4:41 pm EST.
The OP Stack’s Fault Proof System, the technology behind the Base blockchain from crypto exchange Coinbase, went live on the OP Goerli testnet on Monday.
The launch aims to close a criticized security weakness, while also potentially preparing zero-knowledge (zk) proofs on the ecosystem.
The OP Stack’s first fault proof system is live as an alpha on OP Goerli Testnet!
This system leverages the power of the OP Stack’s modular design to lay the foundation to build out a multi-proof dispute system that can include ZK proofs.https://t.co/tqSr6EZHZd

In July, Optimism announced it was moving forward with two proposals from Web3 firm O(1) Labs and zk-rollup infrastructure provider RISC Zero to bring zk-proofs to the blockchain.
Zk-proofs are a cryptographic method where one party can prove to another that an underlying value or statement is true without revealing any other information about that value, which preserves privacy and security. Both proposals, which were in response to Optimism’s request for designs that tackled efficient,secure cross-chain communications, suggested that Optimism make improvements to its fault-proof systems.
The new Fault Proof System in testnet has three core components: a Fault Proof Program (FPP), a Fault Proof Virtual Machine (FPVM), and a dispute game protocol. The parts work together to detect and handle malicious activities to better secure the OP Chains and OP Stack Chains in the ecosystem.
Due to the modular nature of OP Stack, FPP and FPVM can also operate independently .In time, developers will eventually be able to create custom-built fault proof systems, such as validity proofs like zk rollups or zero-knowledge virtual machines (ZKVM).
