Summary
1 The invention relates to a method which aims to prevent DoS attacks. In particular, a trusted third party in the form of a certification authority (-CA-) 120 receives a request to facilitate a blockchain operation between one device 110 and another device 105, sends a message back to the requesting device that includes a prompt for the requesting device to meet one or more conditions. The CA 120 completes the requested blockchain operation when the one or more conditions are met and denies the request if they are not met. Therefore, for example where the condition is a payment of a fee, requests of entities that have not paid the fee are ignored to prevent DoS attacks. The invention was found to be lacking an inventive step and was also excluded as a method of doing business. The application was refused.
