Fiber Link Product Delivery Report

1. Project Overview

Fiber Link is a payment and tipping infrastructure designed for community use cases, with initial support focused on Discourse communities. It enables community users to initiate Tips directly from posts or replies, and provides an end-to-end flow for payment request creation, payment, settlement, creator revenue visibility, and withdrawals.

The focus of this delivery is to move Fiber Link from an “engineering-usable implementation” to a “product-ready, reviewable, verifiable, and deployable” state. In addition to the Live Demo and Milestone 3 acceptance evidence, the main product documentation has also been completed for reviewers, deployers, Discourse administrators, and service operators.
