Abstract: According to one embodiment, a blockchain service device includes an interface, a memory, and a processor. The interface receives a request to perform a blockchain service. The blockchain service includes generating a local key using a private key stored on a user device. The request includes a transaction restraint. The memory stores software used to generate an input to generate the local key. The processor generates the input in response to the request. The input is used to generate a local key that includes the at least one transaction restraint. The interface communicates the input and receives a first block in response to the communication of the input. The first block is generated using the local key and the transaction restraint. The processor inserts the first block in a blockchain, wherein inserting the first block in the blockchain preauthorizes a transaction that is limited by the transaction restraint.
