Odaily News Ink, the Ethereum Layer-2 scaling solution incubated by Kraken, will enable a permissionless fault proof mechanism this Thursday, which is an important technological advancement in its rapid development. Ink became the first super chain network to launch a multi-"challenger" mechanism after the Optimism mainnet test. In the early stage, the challenger system was operated by the smart contract automation protocol Gelato and Kraken respectively. Fault proof is an important function of Optimistic Rollups, allowing users to question the validity of transactions and correct erroneous states. Ink's initial challenger funds were provided by Kraken with 49 ETH (about 156,000 US dollars), and users can also participate in the challenge by staking ETH, thereby promoting decentralization of the chain.
