Service Dist0rtion Protocol

SDP offers different services to its members.

SDPFS private network

SDPFS is Social Dist0rtion Protocol File System. SDFPS is a private network of IPFS nodes. The network is private because we might share information about the future that would modify the course of events, causing a fork of our current branch of reality.

Prerequisite: install IPFS and the pre-shared key

Download the latest IPFS version from:

• https://dist.ipfs.io/#go-ipfs

Unpack it, run ./install.sh or put it somewhere in your $PATH.

Create the sdpfs command by copying this script somewhere in your $PATH:

#!/usr/bin/env bash

LIBP2P_FORCE_PNET=1 IPFS_PATH=~/.sdp/ipfs ipfs "$@"

Private network setup

Create the home directory for sdpfs

mkdir -p .sdp/ipfs

Get the swarm key from another member and put it in ~/.sdp/ipfs/swarm.key.

Now run the following:

# Init the sdpfs repository
sdpfs init

# Enable experimental feature to not duplicate files
sdpfs config --json Experimental.FilestoreEnabled true

# Remove the bootstrap nodes, we have a private network
sdpfs bootstrap rm --all

# Add a new bootstrap endpoint
sdpfs bootstrap add /ip4/138.201.174.111/tcp/4001/ipfs/QmYuqXRt6HGEnD8vp5bcrDQJdhwt9q9innSWfU35d62qWD

Use sdpfs

Now you can use sdpfs as you would use ipfs. For example if you want to start the daemon run:

sdpfs daemon

And visit a member homepage by opening this friendly URL:

• http://localhost:8080/ipns/QmQK5P4pXeUeEsd7mBMCZcd18Ta3qBcG71tEa8fyPchVHU/

Bootstrapping a private network

You don't need to to this, someone else did it already.

Network bootstrap

A private network needs a pre-shared secret called swarm key. The key is generated once and shared across all members' nodes. To generate the key, run:

echo -e "/key/swarm/psk/1.0.0/\n/base16/\n`tr -dc 'a-f0-9' < /dev/urandom | head -c64`" > ~/.sdp/ipfs/swarm.key

Then share ~/.sdp/ipfs/swarm.key with SDP members.
