S4

S4 is 100% compatible S3 storage, accessed through Tor and distributed using IPFS.

Tor hides the physical location of the S4 server. IPFS makes your data permanently accessible and is impossible to take offline once it has been published. A sidecar docker container is provided to seamlessly proxy requests from your existing S3 code over Tor to S4.

Create S4 server

You can set-up your own local S4 Server in just 4 commands.

$ git clone [email protected]:Ideea-inc/S4.git

$ cd S4/

$ docker run -it --rm -v $(pwd)/data/tor:/web ideea/s4-tor-proxy generate ^s4

$ docker-compose up

Node.js AWS-SDK Example

Once you have created your local S4 server, you can test it using the included example. This demo shows the current Node.js AWS-SDK working with the sidecar docker container to proxy the AWS S3 requests over Tor back to your local S4 server.

$ cd example/

$ docker-compose up -d

$ docker exec -ti my-app node src/index.js

Architecture

Tor does not just provide anonymity, Tor acts as a DNS. S4 uses Tor hidden services, data is uploaded into an S4 bucket over Tor. This also means you can create a free .onion domain name without needing any 3rd-parties. A sidecar container is provided to seamlessly proxy requests from your existing S3 code over Tor to S4.

IPFS acts as a CDN. Each S4 bucket is published to IPFS under a separate key allowing you to address your files using any existing IPFS HTTP gateway like this https://ipfs.io/ipns/[BUCKET-KEY]/image.jpg. This link will never change or go offline, the more people who request it, the faster the data will be returned to the user.

Deploy a Cloud Node

If you want to try S4 in production or if you would like to support my work you can Deploy a Cloud S4 Node on my API platform.

Build a Node

• Install Ubuntu 20.04

• $ git clone [email protected]:Ideea-inc/S4.git

• $ cd S4

• $ ./install

• $ sudo mount /dev/XXX /mnt/ssd

• $ sed -i "" "s#S4_ROOT=.*#S4_ROOT=/mnt/ssd#" .env

• $ sed -i "" "s#ACCESS_KEY=.*#ACCESS_KEY=$(openssl rand -hex 10)#" .env

• $ sed -i "" "s#SECRET_KEY=.*#SECRET_KEY=$(openssl rand -hex 20)#" .env

• $ sudo reboot

• $ docker run -it --rm -v /mnt/ssd/tor:/web ideea/s4-tor-proxy:arm64v8 generate ^s4

• $ docker-compose up
