ZeroNet Decentralized Website Hosting - Setup and Site Creation
ZeroNet combines Bitcoin-style public key cryptography with BitTorrent-based content distribution to create a decentralized web platform. ZeroNet sites are identified by Bitcoin public keys and distributed among visitors who also serve the content to subsequent visitors. Sites are accessible even when the original publisher's computer is offline as long as other seeders are available. This guide covers the technical setup of ZeroNet on a VPS, site creation, and the specific anonymity properties and limitations of the ZeroNet approach compared to Tor hidden services.

ZeroNet Architecture and Anonymity Properties
ZeroNet sites are identified by Bitcoin addresses (public keys). The site owner controls content updates through the corresponding private key; any update signed by the correct private key is accepted by the network and propagated to seeders. Visitors automatically become seeders of sites they visit, creating a distribution network without central hosting.
ZeroNet's anonymity properties are fundamentally weaker than Tor. By default, ZeroNet peers communicate directly, making IP addresses of both site seeders and visitors visible to each other. Optional Tor integration routes ZeroNet traffic through Tor, adding anonymity for the operator's IP address. Without Tor integration, ZeroNet provides content persistence and censorship resistance but not publisher anonymity.
The BitTorrent-like architecture means that content is openly visible to all participating peers, including law enforcement observers who can participate as regular peers. Unlike Tor hidden services where the server's location is cryptographically protected, ZeroNet sites' seeder IPs are visible to anyone connected to the network who requests the content.
Running ZeroNet with Tor Integration
Install ZeroNet from the official repository and configure Tor integration for improved anonymity:
apt install tor python3 python3-pip pip3 install msgpack gevent git clone https://github.com/HelloZeroNet/ZeroNet.git cd ZeroNet && python3 zeronet.py --tor enable --tor_proxy 127.0.0.1:9050 --tor_controller 127.0.0.1:9051
With Tor enabled, ZeroNet routes its connections through Tor, hiding the VPS IP from other ZeroNet peers. Site seeding activity is still visible to the Tor network (exit nodes see ZeroNet protocol traffic), but the VPS IP itself is not directly exposed to other ZeroNet peers. This provides meaningful anonymity for publishers compared to non-Tor ZeroNet operation.
Note that Tor integration increases latency significantly and reduces throughput compared to direct ZeroNet operation. For sites with high media content (images, video), the combination of ZeroNet's BitTorrent distribution and Tor's latency can result in slow initial load times. Text-heavy sites load more acceptably.
