Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for implementing a mutual aid network. One of the methods includes maintaining a particular blockchain specifically for handling requests for aid from a group of members; receiving transaction data encoding user responses to queries from the blockchain network for requesting the user responses regarding a particular request for aid; executing the smart contract using the particular blockchain to process the transaction data; in response to response results indicating that sufficient user responses have been received from the members of the subset of the group, and that a sufficient percentage of the subset of the group have agreed to the particular request for aid, computing an amount of contribution due to each member of the group; and instructing a gateway to trigger the amount of contribution to originate from each member of the group.
