I created a small canister that tests how well the IC can keep a secret. The canister running behind https://6b4pv-sqaaa-aaaah-qaava-cai.raw.ic0.app/ has used the Internet Computer’s random tape to get a random value and keep it in memory. If you find a way to obtain that secret value (or manage gue…

Great challenge. Would like to know how i can call the http_request from the local machine ? http://localhost:8000/?canisterId=qoctq-giaaa-aaaaa-aaaea-cai&id=qoctq-giaaa-aaaaa-aaaea-cai

Good question, but maybe worth a separate thread on this forum, to keep this one a bit topical?

Hope you will explain the answer. I only incremented the failed attempts counter :sweat_smile:

I won’t be able to reveal the answer - this would require a bug to surface, and I don’t know of such a bug yet! :slight_smile:

Could you all work on(or direct me to) the source for the front end asset canister code? It would be interesting to get at the url parsing code that I don’t want to have to rewrite.

The foundation and ICA should seriously consider something like this with A LOT more ICP in it. You could fill it with a bunch of cycles and let the foundation be the controller such that when the canister dies it refunds the foundation. (I think that is what happens if I remember correctly). This…

[image] skilesare: and let the foundation be the controller Too late, I am not longer the controller of this one. The foundation is free to run their own capture-the-token challenge :slight_smile: Otherwise I agree, up-ing the stakes here would be interesting and worthwhile. Although I am no…

The canister signature feature is now enabled system-wide, so the 1 ICP held by the canister is actually redeemable
