A transaction platform may provide access, to a distributed shared data structure, to a user device and a service provider device. The transaction platform may store, in the distributed shared data structure, user information associated with a user and service information associated with a service provider. The transaction platform may process a transaction between the user and the service provider by using a first set of processing nodes to generate a first transaction result and a second set of processing nodes is to generate a second transaction result. The transaction platform may determine whether the first transaction result and the second transaction result are the same, and may store, based on determining that the first transaction result and the second transaction result match, a smart contract, associated with the transaction, in a distributed ledger.
