Overview

StarGate is a specification to extend the IPFS gateway to support trustless, multipeer data transfer of fairly complex queries.

This repo is a prototype design and implementation of StarGate, containing a simple executable that implements a Stargate server and client (client still in development as of 1/18/2023).

For more information on how Stargate works and its core design goals see the StarGate talk from the Move The Bytes Working Group: https://www.youtube.com/watch?v=qbKZmmMZePs and the StarGate protocol specification

Setup

To install Stargate, run:

> go install github.com/ipfs/stargate/cmd/stargate@latest

Then, setup your repo with:

> stargate init

Note: You don't really have to run stargate init for the time being cause the other commands will initialize everything if it's not done.

Usage

Import data

Import the current directory, recursively:

> stargate --vv import .
Sending CID bafybeidwarsw46q7wx5jrojwzgg4smvmgvgj23chzmybidten3l7wjnrva through the Stargate!

Import a file:

> stargate --vv import ~/Downloads/testvideo.mp4 
Sending CID bafybeigkkzgkd6z33jaczjhrmjb5m3jwqyn7zbbfvmy2ekfm6dievp5kdy through the Stargate!

Run the Stargate Server

> stargate --vv server

(the server can start any time and you can import while the server is running)

Fetch (with CURL for now)

Fetch the root directory:

> curl -v http://localhost:7777/ipfs/bafybeidwarsw46q7wx5jrojwzgg4smvmgvgj23chzmybidten3l7wjnrva > root.car

Pathing:

> curl -v http://localhost:7777/ipfs/bafybeidwarsw46q7wx5jrojwzgg4smvmgvgj23chzmybidten3l7wjnrva/go.mod > go.mod.car

> curl -v http://localhost:7777/ipfs/bafybeidwarsw46q7wx5jrojwzgg4smvmgvgj23chzmybidten3l7wjnrva/pky/types.go > types.go.car

Fetch a file:

> curl -v http://localhost:7777/ipfs/bafybeigkkzgkd6z33jaczjhrmjb5m3jwqyn7zbbfvmy2ekfm6dievp5kdy > testvideo.mp4.car

Fetch a file, but don't send leaf blocks (useful for multipeer):

> curl -v http://localhost:7777/ipfs/bafybeigkkzgkd6z33jaczjhrmjb5m3jwqyn7zbbfvmy2ekfm6dievp5kdy?noleaves  > testvideo.mp4.dag.car

Fetch a range (of the flat file, not the car):

> curl -v http://localhost:7777/ipfs/bafybeigkkzgkd6z33jaczjhrmjb5m3jwqyn7zbbfvmy2ekfm6dievp5kdy?bytes=0-1000000  > testvideo.mp4.start.car

Documentation

Roadmap

A list of things to do:

• Complete Fetch Command
• Add Tracing and Metrics
• MOAR documentation
• Measure Performance
• Optimizations
• Filecoin Chain Resolver

But sadly, little time for original author to complete them
