Remote computation has numerous use cases such as cloud computing, client-side web applications or volunteer computing. Typically, these computations are executed inside a sandboxed environment for two reasons: first, to isolate the execution in order to protect the host environment from unauthorised access, and second to control and restrict resource usage. Often, there is mutual distrust between entities providing the code and the ones executing it, owing to concerns over three potential problems: (i) loss of control over code and data by the providing entity, (ii) uncertainty of the integrity of the execution environment for customers, and (iii) a missing mutually trusted accounting of resource usage.
