The volume of traffic generated by modern Distributed Denial-of-Service (DDoS) attacks suggests that centralized defenses are not the most effective approach to counter these attacks. An alternative to reduce the burden of detection and mitigation is to combine centralized defense systems, creating a global and cooperative protection system. However, existing approaches suffer from the complexity of deployment and operation across different systems. Blockchains appear in this scenario as an alternative to simplify the exchange of information in a cooperative defense. This work evaluates in both local and global experimentations the performance of the blockchain system proposed in concerning the latency to perform the signaling of blacklisted addresses.
