#13curious how you'd keep all parties winning at once on the platform (supply&demand& traders maybe?) Are you planning to make money on float / spread / flat fee?

#14How do you prevent sellers from fraudulently selling future capacity they don't actually have?
Great question. When we list a capacity from a provider, the capacity lists only after it's contracted and attested, and the provider guarantee travels with the claim. If delivery fails, that's on us to remedy, not on the buyer to chase a stranger.

#15how do you deal with data security
we lock down the nodes themselves so that only the hypervisor has direct access. we take this pretty seriously.

So in other words, you're screwed?

Good question. this is something we built around from day one. Users pay 100% up front for specific nodes on the exact weeks they want. No leverage, no margin, no cash settlement. This is honestly not that much different from you booking a hotel.
What does "no cash settlement" mean? If I sell a reservation, do I not get cash?
So yes, you do get cash. when i said cash settlement, i was referring to how the contract itself ends, unrelated whether you can sell it. A cash-settled contract means it never delivers anything and at expiry it just pays out the difference between your price and an index price, which makes it a pure price bet.
on computable, whoever holds the reservation when the week arrives gets the actual nodes when they redeem for usage. so selling your reservation to someone else beforehand is no different from reselling a concert ticket. and when you sell, the buyer takes over the claim, you get their money, and the contract still ends with someone getting the GPUs.
hope that clears up.

#18Interesting approach. How do you ensure liquidity if buyers and sellers want different weeks? Is there a market maker, or is everything matched through the auction?
I imagine they’re building the supply side as well, where you can bid your fixed GPU. My question with this stuff is how do I know my data is secure on these for-rent boxes? What steps are taken to sanitize the GPU between runs etc.
we take this pretty seriously. we lock down the nodes themselves so that only the hypervisor has direct access. and between customers, we don't just sanitize disks. we actually delete them entirely and spin up a fresh VM from a clean qcow2 base image, so no prior customer data persists.
