Solution Highlights

• Attacks like Distributed Denial-of-Service (DDoS) pose a growing threat to computer networks and internet services.
• Existing strategies for mitigating DDoS attacks are inefficient because of lacking resources and inflexibility.
• Ethereum blockchain enable new ways to fight DDoS attacks: Using smart contracts, IP addresses of attackers can be singalized without additional infrastructure.
• Using multiple smart contracts for signalisation of DDoS attacks and compares them.
• The solution advice about the performance and costs and evaluates the overall feasibility and effectivity for fighting DDoS attacks.
• Thesolutin support a larger number of addresses with a bloom filter.
• Customer Certified IPv4() to allow more hierarchies to map subnets accordingly.
