Bi-weekly update tracking community contributions to the growth of the Fiber Network

The most exciting work happens when builders take the lead.

Ahead of Bitcoin 2026, here’s a quick snapshot of what’s been happening across community projects building with Fiber.

Fiber-Checkout: Stripe-Style React Payment Library Now Completed

The fiber-checkout project has submitted its completion report, marking the delivery of a new payment tool for Fiber Network.

Built for React and Next.js, it wraps Fiber payment flows into a simple checkout component, replacing complex manual steps with a ready-to-use checkout component.

What shipped:

  • npm package
  • live demo
  • documentation
  • tested integrations

It was delivered within the planned 4-week timeline and is now ready for developers to plug into real apps.

  • Support: Spark Program

The Fiber Link team shared its latest Milestone 3 update. The long-running public Testnet demo remains stable and operational, with:

  • 109 successful tips
  • 32 successful withdrawals
  • 1 channel rotation for replenishing liquidity.

Next up: improved operator-friendly deployment and plugin installation guides to support future handoff and independent operation.

  • Support: CKB Community Fund

Dular: Mobile Money Stablecoin Wallet on Fiber

Dular is building a stablecoin wallet designed for users in Africa, Southeast Asia, and Latin America, where mobile money is already the default payment experience. With Dular, instead of complex crypto wallets, users can:

  • Send funds via phone numbers
  • Deposit and withdraw through services like M-Pesa
  • Access wallets via USSD on feature phones, without internet

Dular uses Fiber’s payment channel network to enables near-instant transfers with extremely low fees, while supporting native stablecoins and future local currency assets.

  • Status: The project is currently updating its application based on reviewer feedback in order to proceed to formal committee review.
  • Check it out: Forum link
  • Application for: Spark Programme

Backr: Creator Memberships Powered by Fiber

Backr is a creator platform that enables paid posts, subscriptions, and community interaction through wallet-based identities instead of traditional accounts.

How payments work:

  • Subscriptions and renewals are paid via Fiber Network
  • Creators selling memberships run their Fiber Nodes and configure its JSON-RPC endpoint in the app
  • Backr coordinates Fiber invoice creation and payment handling on the server side, keeping the browser out of the payment flow.

This keeps payments non-custodial while giving creators full control over their setup.

LUME: Explores a Programmable Yield Layer

A community proposal LUME proposes a programmable yield layer built on top of RGB++, aiming to connect Bitcoin and CKB through yield, liquidity, and network participation

The idea:

  • Users lock assets like CKB into a reserve-backed system
  • Earn yield based on network activity and fees
  • Build liquidity between BTC and CKB

In this design, Fiber Network would serve as a bridge and liquidity layer, connecting flows across systems.

Idea Feasibility Check: AI Workflow Monetization

Creators of open-source AI image/video generation often face a recurring issue: they build high-quality workflows, where the key values lies in a few critical parameters (e.g. CFG, steps, shift). These are easy to copy and redistribute without permission.

This idea explores a way to monetize AI workflow (especially ComfyUI) by separating its key parameters:

Concept:

  • Main workflow stays open-source and runs locally
  • Key parameters (like CFG, steps, tuning values) are encrypted and stored cheaply on CKB
  • Fiber handles parameter retrieval and delivery back to the users

This enables a pay-per-use or pay-per-generation monetization model for creators while preserving an open ecosystem.

The ecosystem is still early, and most of what matters is happening in public — in forum posts, prototypes, and half-finished ideas that slowly turn into real products.

If you’re building something, here’s how we can support you:

  • Spark Program: up to $2,000 for early MVPs (1–2 months)
  • CKB Community Fund: DAO grants for broader ecosystem work

Share your progress on Nervos Talk, even if it’s just a rough idea. That’s usually where the interesting things start. We’ll likely feature more of these in the next Fiber Pulse.
