剛剛再睇過確認 IPFS 係要有人做 seed 長放啲資料
所以 IPFS 係一個工具去令中國無法封禁,但唔好理解為可以免費長放
//IPFS will not automatically distribute your data on other nodes. It’s more like bittorrent, it’ll creates a global filesystem namespace where you can add files on your machine, tell others about them (e.g., /ipfs/Qm…) and they can then use the IPFS network to (a) find where the files are stored (your machine) and (b) fetch them.
If you want to actually get others to store your files, you’ll have to pay them out of band. If you google “IPFS pinning service”, you’ll find some existing services willing to do this.
