made with Flux, Serste digital art 2 LoRa, via NightCafe', with prompt from the Arbitrum Docs: 'AnyTrust is a variant of Arbitrum Nitro technology that lowers costs by accepting a mild trust assumption. The Arbitrum protocol requires that all Arbitrum nodes, including validators (nodes that verify correctness of the chain and are prepared to stake on correct results), have access to the data of every L2 transaction in the Arbitrum chain's inbox. An Arbitrum rollup provides data access by posting the data (in batched, compressed form) on L1 Ethereum as calldata. The Ethereum gas to pay for this is the largest component of cost in Arbitrum. AnyTrust relies instead on an external Data Availability Committee (hereafter, "the Committee") to store data and provide it on demand. The Committee has N members, of which AnyTrust assumes at least two are honest. This means that if N - 1 Committee members promise to provide access to some data, at least one of the promising parties must be honest. Since there are two honest members, and only one failed to make the promise, it follows that at least one of the promisers must be honest — and that honest member will provide data when it is needed to ensure the chain can properly function.'
