ZeroNet is a decentralized and open source web platform. Its based on BitTorrent(p2p) technology and BitCoin cryptography. The contents published by users can never be deleted because theyre distributed directly to other visitors without any central server. The content remains online so long as at least one user serves it. It’s impossible to shut down websites in the ZeroNet. It is always online with no downtime and can be accessible if your internet is unavailable if you have visited the website previously.”]
