How does IPFS prevent DDOS attacks?
I recently came across information suggesting that IPFS has been utilized as a defense against DDOS attacks. While I have a basic understanding of how DDOS attacks function in Web2, I am curious to learn how IPFS contributes to preventing such attacks. Could someone please provide a concise explanation of how IPFS helps in mitigating DDOS attacks? Thank you in advance for your insights.

1A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal functioning of a website or online service by overwhelming it with a flood of internet traffic. In such an attack, the attacker aims to render the targeted website or service inaccessible to its intended users. However, when it comes to IPFS (InterPlanetary File System), the nature of the system prevents DDoS attacks from being effective. Here's why:
-
Location-address vs Content-address: In traditional systems, websites are location-addressed, meaning they are identified by their IP address. This makes them vulnerable to DDoS attacks, as attackers can flood the IP address with traffic, causing the website to become inaccessible. However, IPFS is content-addressed, which means that files are identified by their content, not their location. Each file is assigned a unique cryptographic hash, which serves as its address. This decentralized approach makes it extremely difficult for attackers to target and disrupt specific websites or services.
-
Decentralization and Distribution: IPFS operates on a peer-to-peer network, where files are distributed across multiple nodes. When a user requests a file, it is fetched from multiple nodes simultaneously, making it highly resilient to DDoS attacks. Even if one or more nodes are targeted, the file can still be retrieved from other nodes in the network. This distributed nature of IPFS ensures that no single point of failure exists, making it challenging for attackers to overwhelm the system.
-
Traffic Distribution: IPFS utilizes a distributed hash table (DHT) to store and retrieve files. This DHT ensures that files are evenly distributed across the network, preventing any single node from becoming a bottleneck. As a result, even if an attacker tries to flood a specific node with traffic, the load is distributed among other nodes, preventing the targeted node from being overwhelmed.
In conclusion, the content-addressed and decentralized nature of IPFS makes it highly resistant to DDoS attacks. By eliminating the reliance on specific IP addresses and distributing files across multiple nodes, IPFS ensures that websites and services remain accessible even in the face of malicious attempts to disrupt them.
