The InterPlanetary File System (IPFS) is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting all computing devices.
There are some privacy considerations that users should be aware of before enabling a local IPFS node:
- By accessing content over IPFS, your device becomes a host for the content for an unknown amount of time until the local cache is cleared.
- The content that your IP has accessed over IPFS is essentially public information. If your node is hosting the content, anyone can do a distributed hash table (DHT) lookup for the content and find your IP. If you aren't, the DHT node operator can still see that your IP is looking for the content.
- Since peer IDs are long-term identities, an attacker who does lookups on your peer ID can track your IP address over time.
- By visiting a page over IPFS, you give that page permission to make you a host of any resources that it loads.
