This is a half-baked idea about preventing torture through cryptography

As a way to combat torture, rather than owning and controlling access to your own private key, the end access to the key is controlled by majority vote by a large network that must allow the key usage, perhaps after seeing a message from the individual requesting access.

In this setup, there’d be no motivation by a captor to torture someone in order to get access to their private key (and thus all their secrets) - assuming a passphrase that only the captive knows. The entire network would have to consent to the access, which they wouldn’t do if the subject was captured.

But couldn’t the captives torture the victim into recording some sort of “legit” plea to their network to release access? Hm..
