Tor hidden service

Tor hidden service routes requests to Blockfrost's API, acting as a privacy-respecting bridge. This allows anonymous, secure access to Cardano services.

By utilizing Tor hidden services, you can mask you online identity and anonymize your connection to Blockfrost and Blockfrost API. This added layer of privacy ensures that sensitive information, such as transaction details or account information, remains confidential.

For those of you extra concerned about privacy.
