Kraken's incubation layer two network Ink has partnered with Optimism to introduce permissionless fault proofs

according to The Block, Kraken's Ethereum Layer-2 scaling solution Ink will enable a permissionless fraud proof mechanism this Thursday, marking an important technological advancement in its rapid development.

Ink becomes the first superchain network to launch a multi-"challenger" mechanism after testing on the Optimism mainnet, initially operated by the automated protocol Gelato and Kraken running the challenger system. Fraud proofs are a crucial feature of Optimistic Rollups, allowing users to challenge the validity of transactions and correct erroneous states.

The initial challenger fund for Ink is provided by Kraken with 49 ETH (approximately $156,000), and users can also participate in challenges by staking ETH, thereby promoting on-chain decentralization.
