Implementations may involve a processor at a node within a network of nodes receiving a set of mechanisms, each defined by a provider action and a feasible contract. The processor defines a recipient loss function based on these mechanisms and determines the mechanism that minimizes this function. A smart contract is generated based on the selected mechanism and deployed to a blockchain maintained across the network by broadcasting it to the nodes. The processor receives a transaction address from the blockchain corresponding to the smart contract and stores this address in a database on an electronic storage device connected to the processor. Implementations facilitate efficient deployment and tracking of smart contracts within a distributed network, optimizing user-defined criteria through automated mechanism selection and blockchain integration.
