With the right malware, your CPU rents itself as part of a Botnet.

I remember doing the Seti at Home and Folding at Home projects as a screen saver that used CPU time to solve problems. That was for charity.

How is this different than mining for Bitcoin or any other virtual currency? I want to make sure my CPU is not used for illegal means and then the FBI busted down my door because my CPU was part of a peer to peer network serving kiddie porn?

Just some observations: - I don't have any info on how this works from the repo. 99% of people will click on the repo and click back because of the lack of this. I went on google and found a [this]( https://sideprojects.net/posts/NB697xnBrWQioywoP/rentmycpu-r... ) link, but still no information. - How are payments processed? Do you need to trust the other party a good amount? As a cpu cycle seller, how do I know I'll…

This reminds me of homomorphic encryption: you can perform computations on data while it remains encrypted, which would solve the trust problems you mention afaict. This seems like it would have enormous potential to change the cloud landscape. https://en.m.wikipedia.org/wiki/Homomorphic_encryption

My understanding (which is admittedly very little) though is that homomorphic encryption requires many times more computations compared to running on unencrypted data, so that could dampen it's usefulness.

Well, it's WebAssembly, so there can't possibly be any exploits!

Wait, is WebAssembly known to be insecure? This is news to me.

There have been several PoCs of microarchitectural attacks, such as Rowhammer or Meltdown/ Spectre/ MDS, implemented in webassembly.

Earlier quoted context omitted.

I'd be worried about offering storage to random people, but what kind of compute are you worried about doing? I guess someone could use this as a kind of proxy, right? Like have your system perform some attack or send some communication.

> I'd be worried about offering storage to random people Isn’t that precisely how IPFS works?

IPFS mostly functions with people choosing specific files to keep available.

How is that different from mining ETH, which is basically running others' programs (smart contracts) in exchange for ETH.

Every Ethereum smart contact is validated (run) on every node in the Ethereum network, in order to achieve distributed consensus. It should be possible to be thousands of times more efficient than that (which suggests they could achieve much lower prices for buyers combined with greater rewards for CPU owners).

I would love to be able to rent people's spare gpu compute. It's be a lot cheaper than aws or any other cloud service

Not necessarily.

If your workload can be split, in many cases the amount of places to bring your data to would mean expensive and slow data transfer - N times to N points vs once to AWS.

In 2007 when distributed computing was still a New Kid On The Block, I shared an idea with a colleague for what I considered to be a good idea at the time: Distributed computing for hire. Families around the world have reasonable amounts of computing power that sits mostly unused; why not make a few bucks doing things similar to Folding@Home Seti@Home, but for a price? Get paid for your computations. Of course this w…

Can't agree more on this :)
