Abstract
A computer-implemented method for authenticating requests from a client running trialware through a proof of work protocol is described. A request received from a client running trialware is analyzed. A cryptographic puzzle is generated if an authentication token is not included with the request. The cryptographic puzzle is transmitted to the client. A solution to the cryptographic puzzle received from the client is analyzed. A response to the request is generated if the received solution to the puzzle is validated.
