Tor adds another layer to the onion with a new relay encryption algorithm - boosting resilience and security across the board

Tor Browser.

• Tor dumps tor1 and moves to a stronger, research-driven relay encryption system
• CGO introduces modern protections that block tagging attacks across the network
• Wide-block encryption makes modified cells unrecoverable and stops predictable interception attempts

Tor has introduced a new relay encryption system called Counter Galois Onion (CGO) to replace the older tor1 algorithm.
