Performing the read call may include reading a list of registered addresses stored on the blockchain, determining whether the list includes the signing address; and providing an output indicating whether the list includes the signing address. The method may further include executing, by the at least one distributed node, a registry contract stored on the blockchain to perform a read call from the DApp contract, the read call including an identifier of the decentralized application. Performing the read call may include reading a list of registered applications stored on the blockchain; determining whether the list includes the identifier; and if so, providing an output indicating an address of the entitlement contract.
