Re: protocols with trust-minimization in mind, you may be interested in Multi-Party Relays (vs. traditional VPNs which are Single-Party Relays): https://www.privacyguides.org/articles/2024/11/17/where-are-...

With Multi-Party Relays you no longer have a trust a single entity not being malicious or compromised.

Disclaimer: I run obscura.com, which does exactly this with Mullvad (our partner) as the Exit Hop.
