Abstract
Techniques are provided for proof-of-work based on runtime compilation. Key generation code is partitioned into a set of code blocks. The key generation code generates an expected key value when compiled and executed. A shuffled set of code blocks is generated by reordering the set of code blocks. A client computing device is provided the shuffled set of code blocks and problem-solving code that, when executed at the client computing device, reconstructs the key generation code to generate a submission value by performing one or more compiling iterations. Each compiling iteration comprising reordering the shuffled set of code blocks to generate test code, and attempting to compile and execute the test code to generate the submission value. It is determined that the client computing device fully executed the problem-solving code based on the verifying the submission value.
