Inventorying the 15 types of DAOs: how to reshape the world?

The interface between the distributed ledger and external data is a weakness of the DeFi stack, as the blockchain cannot directly query APIs. Instead, they must rely on third-party notary services called oracles to transfer data, with varying degrees of decentralization. To completely close this gap, API3 is building a multi-chain compatible network, governed by [an Aragon-based] DAO, to incentivize API operators to serve their own oracles. This is achieved by a free and open source middleware called Airnode, which connects any web API directly to any blockchain application.
