Hi, i’,m trying to implement reward based on hosting file in ipfs.
I’m looked all of API, but can’t find any command, with which i can check if remote node has pinned file or caт provide it.
As i could understand by reading this forum, that findprovs can show info about nodes, but, this list updating ~24 hours, so it’s not solution to the proble.
I Thought about some crypto functions with keys, to prove, but can’t finish this idea.
Pls if someone know about some API or maybe any ideas how can i prove that node has file?
