AlienX is a variant of Arbitrum Nitro technology that lowers costs by accepting a mild trust assumption.AlienX, a variation of Arbitrum Nitro technology, reduces costs by relying on a slight trust assumption. Unlike the Arbitrum protocol, where all nodes, including validators, need access to L2 transaction data, AlienX employs an external Data Availability Committee ("the Committee") to store and provide data upon request. The Committee consists of N members, with AlienX assuming the honesty of at least two. This ensures that even if N-1 Committee members pledge to provide access to certain data, at least one honest member will fulfill the promise. Thus, the chain can operate effectively with the assurance that necessary data will be available when required.
