We compare web vs. crypto service models across two dimensions: the production model (from centralized to decentralized) and the data model (from custodial to non-custodial). The more decentralized and non-custodial a service, the more distributed its cost structure. This is important because markets tend to allocate value along the line of costs. So the more we decentralize the cost structure of a service, the more broadly we distribute its value.
