Is this a project you guys are going forward with, or just a proposed solution to the problem?

Sorry, should have made that clearer in the main text: This is an actual project that is funded (although not very well for now).

About your concern: I think that in such a large system, the reward for finding a cheater would be magnitudes higher than the reward to carry out the computation in the first place and there are long-term deposits such rewards can be paid out from.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
