- The privacy-oriented browser #Tor has introduced a #Proof-of-Work (PoW) defense for Onion Services with the launch of Tor 0.4.8.
- This #PoW defense is designed to counter denial-of-service (DoS) attacks by giving priority to verified network traffic.
- Tor's PoW #system is dynamic and responsive, remaining inactive during normal usage to ensure a smooth user experience.
- However, during periods of pressure on Onion Services, the mechanism activates, requiring incoming client connections to execute more complex operations.
- Users are recommended to update their #Onion Services to version 0.4.8 in order to benefit from this new defense mechanism.
