Lightning Browser Extension

During the last hacksprint we started a new Lightning Browser Extension to bring Lightning payments to the browser. The goal is to have a lightweight extension that can connect to multiple node implementations.

In this hacksprint we try to continue working on it and get the extension into an usable state. Any ideas and help welcome (specifically React frontent work... ;)

Chatroom to get started: https://mm.fulmo.org/fulmo/channels/ln-browser-extension

Moneysocket

During the last hacksprint, we started working on the Costanza wallet for Moneysocket. That's now complete.

The challenge this time around is to build a chat application that utilizes Moneysocket. An intro video introduces this project: https://youtu.be/0lsvMAFG2Qk.

This will be built with a Python websocket server backend and a Javascript client frontend. Happy for any help or just to chat about related ideas and concepts.

Lightning Labs

We have put together a list of experimental ideas for building on bitcoin in our Lightning Bulb resource. We hope it inspires some great ideas over the weekend. The list includes:

• A native interface to Lightning on the web
• Streaming payments on social platforms
• Distributed storage and retrieval using Lightning
• Distributed compute with Lightning
• Lightning-based metered VPN
• Lightning Paywall Plugin
• Pay-per-use Lightning API calls

For more details, please follow the link.

We'll be hanging out in either the LND Developer Slack or the Lightning Lab Discord.

Lightning payment based online surveys

Last month I did a survey of impediments of Lightning adoption among Bitcoin companies (happy to share the results). The rate of response was ok but could be better.

Why not leveraging the properties of Lightning with instant and private micro transactions to increase the number of responses?

There is open source survey software available. I am looking for support and team members to integrate Lightning payments (and make it available as a web service ideally)

For example, survey creators can determine the reward per answer upfront. Each answer would display a LNURL-withdraw code for the user to get the sats into their wallet.

Happy about ideas and feedback.

Join the LightningATM community in our Telegram group. A group of enthusiasts that have built their own LightningATM's or need help getting there.

Topics that we'll be working on this weekend:

• Help people getting setup with their LightningATM's

• Improve payout method for Lntxbot (payout without Lnurl)
• Github issues with label "hackathon": github.com/21isenough/LightningATM

Jam

We created an open source solution to host Clubhouse like audio rooms based on WebRTC and will work on making it possible to require payments for joining a room

User stories we want to tackle:

• Declare a room to be paid guests only
• Set target address for payments
• Show user possibility to pay with lightning
• Show user lightning invoice
• Create link with room access key when lightning payment went through

Bity VPN

We created a Wireguard powered voucher based VPN service with Telegram bot as a MVP interface. User can buy a VPN data voucher using Lightning and receive a wireguard config file in return. User can then use it to start the wireguard VPN service. It is inspired by the lightning bulb blogpost from the lightning labs team. Code is currently closed sourced but we plan to iterate over it and open source it soon.
