Preventing DDoS Attacks

The domain registration information in a blockchain-based DNS is stored on a distributed ledger. This eliminates the single focal point targeted by DDoS attacks. Blockchain networks have a distributed architecture, spreading the load across multiple nodes. This makes it difficult for attackers to overwhelm a single node and disrupt the system.

A blockchain-based DNS can resist and mitigate the impact of DDoS attacks by spreading the load. Each node in the network has a copy of the blockchain, ensuring that even if some nodes are targeted, others can still provide DNS resolution.

Organizations can control access to the blockchain through a permissioned network. This ensures that only authorized individuals or entities can view or participate in transactions. Privacy of sensitive data is maintained by granting permissions based on factors like identity verification or specific roles within the network.
