Manipulation of credits, indeed, does take place. It's not just collatz.

I mentioned it on Perfect Cuboid in yoyo@home, when using ubuntu boosted credit of atom z3735 to Xeon e5560 bug looks like was just ignored by gridcoin community, yoyo admin "fixed" it by limiting maximum credit (using double check didn't help, all your needed was your wingman running ubuntu too).

Another example is when someone managed to boost his Celeron G1620 (2 threads) RAC to 26000 (~4x Xeon(R) CPU E7- 4870 @ 2.40GHz (80 threads)) in Rosetta@home, won't post link to his profile here, but you can find him in top participants if you want, he crunches for biblepay.

Gridcoin isnt Boinc? Projects assign credit, not Gridcoin. Gridcoin just takes your RAC compares it to the rest of the team's total RAC and gives you a percentage of the project's magnitude for that project.

The only power Gridcoin has in this manner is blacklisting/greylisting a project and communicate with the devs to warn them that there's a problem with their project.

Ah well, that's a shame. But while I ultimately do not agree with this decision, I can understand it to some extent and respect it.

I wonder, though; is the double-check system not considered a sufficient safeguard for cheaters?

A quick zoom around some forums revealed a lot of Gridcoiners abort CPU assigned Genefer21 tasks.

This only show that they were only in it for the Coin and not the Science.

Or their CPU are already occupied with other projects. There's no point keeping tasks that are going to expire before they're even started. I do WCG on CPU and collatz on GPU personally.


I dont really care personally. I wasnt crunching Primegrid anyway but it was clear from the get go that Michael Goetz had a severe hatred for Gridcoin mixed in with a lack of knowledge related to some claims he's made. Now that this decision is made, I'm sure you'll remove GRC from your donation page, right? Or is the hypocrisy small enough for you to swallow it?

If there were unlimited money available, do you think someone would be able to find a way past the double checks?

There's a lot of smart people out there. Jim and I sometimes spend time trying to figure out how someone could cheat here if the wanted to. Usually, most of the "possible" ways are much too difficult for anyone to ever try just to get higher on the leader boards.

Again, you dont know enough about Gridcoin to make an educated statement on this and end up generating FUD. There's a hard limit of how many GRC can be minted in a day. (Most days, it's not reached.) in the past 24 hours, 28k GRC were minted split evenly between the 22 whitelisted projects. ~1200 GRC were or rather would have been generated on Primegrid had it not been greylisted. Now how many people do you think would go out of their way to cheat the system for 12$/day?
