As an example, consider Augur, the decentralized prediction market. Resolving markets through oracles is an important service-level function the application needs. The best place to do it is with the miners, the parties already engaged in consensus-provision.3 But the miners on Ethereum already have a function and it is set in stone: to provide network-wide consensus. Consequently, a lot of the complexity of Augur lies in creating a brand-new process around market resolution with a new set of participants who need to be separately incentivized to perform this role.
