Byway

The Byway is an alternate path for buyers and sellers to reach each other independently that does not rely on Big Tech platforms.

Buyer <------> Matcher <------> Seller

Note: This is an alpha quality release and is not yet ready for use.

Dependencies

• Node v16+
• npm
• Docker / Docker Compose

This has only been tested on with Docker on Intel Macs. It is not guaranteed to work on other platforms.

Getting started

shell git clone https://github.com/jogoodma/byway.git cd byway touch client/apps/byway-ui/.env.seller touch client/apps/byway-ui/.env.buyer docker-compose up -d Verify that the containers are up by running: shell docker-compose ps Be sure to note the host and port numbers that are exposed.

Pico engine set up (Buyer and Seller)

A certain amount of manual configuration is required to get the Pico engine configured for the Byway.

1. Login to the buyer-pico-admin by opening a browser and navigating to the ip and port indicated by docker-compose ps.
2. Create three children nodes with the following names: UserManager, StoreManager, and RequestManager.
3. Open the UserManager pico and install the following rulesets: file:///usr/src/app/rulesets/byway/user/tags.krl file:///usr/src/app/rulesets/byway/user/manager.krl
4. Open the StoreManager pico and install the following rulesets: file:///usr/src/app/rulesets/byway/store/tags.krl file:///usr/src/app/rulesets/byway/store/manager.krl
5. Open the RequestManager pico and install the following rulesets: file:///usr/src/app/rulesets/byway/request/tags.krl file:///usr/src/app/rulesets/byway/request/manager.krl

6. Repeat this process for the seller-pico-admin pico.

7. Open the matcher-pico-admin and install the following rulesets: file:///usr/src/app/rulesets/byway/matcher/matcher.krl

   Channel set up

Using the .env.template file as a guide, record the hostname and byway ECI channels for the buyer, seller, and matcher. Restart the containers after recording the channels.

What is the Byway?

This is a proof of concept project that was created to explore the potential of a decentralized network that could be used to connect buyers and sellers.

For example, a local farmer wants to sell their produce to a local buyer. The farmer has a small IOT Byway device that they use to list their produce for sale. Another local Byway user with a similar device finds the listing and messages the farmer to buy the produce.

Byway Architecture

Overview

The Byway buyer and seller systems are made up of three components. The Pico Engine for implementing most of the logic and network communication, Remix for the front end UI, and a Caddy proxy server that sits atop both.

Buyer and Seller UI

The Byway buyer and seller system uses Remix for the front end UI. Remix is a React framework that takes the middle ground between a typical single page application (SPA) and a server side rendered application (SSR). Routes are used to define pages that the user can navigate to and use a combination of server side and client side rendering to bring a fast and responsive experience to the user. The pages/routes use loader and action functions to define what data is passed to the page for rendering (loader) and what is acted upon when a form is submitted (action).

The loader and action functions are where the communication with the Pico Engine endpoints take place. Either fetching data for display or submitting data to the Pico Engine.

Buyer and Seller Pico Engine

The Byway pico engine system has three main concepts. A user manager for managing users, a store manager for managing stores and items within stores, and request manager for managing requests to buy and sell items.

Byway Matcher Pico Engine

The Byway matcher uses an extremely simple tag based algorithm for allowing buyers and sellers to find products that they are interested in. This is not meant to be a robust solution, but rather a proof of concept that will be improved upon in the future.

Future work

1. An enhanced matcher network.
2. Continue to refine the UI.
3. Improve error handling and add unit test coverage.
4. Add image upload support.
5. Authentication.
