Bridging Tradition and Bitcoin with Open Source

I wanted to share a project we’ve been building: Hong₿ao Bitcoin.

In many Asian cultures, red envelopes (红包 / hóngbāo) are given during New Year and special occasions as a way to gift money with meaning and blessing. We reimagined this tradition for the Bitcoin era: instead of cash, each envelope holds a Bitcoin paper wallet with QR codes for public/private keys.

The fun part: everything behind it is open source.

The generator that creates custom Bitcoin banknote-style wallets
The educational QR codes printed on the envelopes (leading to Bitcoin learning resources)
The design templates themselves

Our goal is to keep this cultural ritual alive while making Bitcoin gifting accessible, transparent, and verifiable by the community.

We’d love feedback from you all on:

How to improve the wallet generator from a security and UX perspective
Ideas for other open traditions that could merge with Bitcoin in creative ways
Best ways to invite contributions and audits from the open source community

Would love to hear your thoughts 🙏

Seeking Collaborators: Now What — An Open Source Project for Participatory Democracy (updated with code)

Hey folks,

I’ve just launched a new open source project called WhatNow:
👉 github.com/AshmanRoonz/WhatNow

The idea is simple:

Now What (Input): people share their voice daily through simple prompts.
Here’s What (Output): collective results are instantly visible in real time, from local → global scale.

The goal is to create a living feedback loop between people and society, one that governments cannot ignore:
convergence (voices in) → emergence (shared goals out).

Right now, the repo has:

[Charter](https://github.com/AshmanRoonz/WhatNow/blob/main/charter.md) — our mission & principles
Roadmap — development path
README with project overview

We’re still at the earliest stage ([Now What - Demo](https://ashmanroonz.github.io/WhatNow/)), so I’d love feedback on the vision, structure, and roadmap before moving toward the MVP (a simple loop: 1 input prompt → 1 output graph).

If this sparks something in you, feel free to:

Star ⭐ the repo
Open issues with feedback or ideas
Join the conversation about building privacy-first participatory tools

Thanks!

Forget work for a while, let's just build sandcastles together <3

Hello everyone,

I see many posts on how to get started with open source contributions in general, One general starting point is to contribute to documentation, like fixing typos, adding proper punctuation etc are really good ways to dip your toes in the water - I started with github docs, just fixing typos literally

Please also be kinder to yourself okay? Large codebases can feel daunting and there are alot of moments where we stare at blank screen wondering which is the right project, take it slow - it's okay to

On that note,

Comfort Commons

—a home in seaside forest for building kinder tools and a kinder world, together. Here, we play, explore, and sometimes build sandcastles so sturdy they make the web a little softer for everyone.

Everything open source, free and everyone is welcome :>

The forest is still new, It's just me and few more travellers along the way drawing welcome in the sand with a stick at the moment, but if you ever want to come with us, to forget work and just play, build sandcastles and dip your toes in the seawater, you are really really welcome <33

We may mess up, the water could feel too cold at times, but as long as we laugh at it and start building the next sandcastle, we will be okay

We have loads of adventures, from research to code

We have roles and pets too!!

# 🦉 Animals = Your Superpowers (Perspectives, Senses, Needs)

Pick a creature that represents your perspective, your needs, or just what feels right:

🦉 Owls: See details others miss, care about visual clarity and contrast
🐬 Dolphins: Hear what others might not, tune the world for clear sound and calm
🦌 Deer: Move gently, know the best paths, care about easy navigation
🦊 Foxes: Clever problem-solvers, make things simple for minds that work differently
🐻 Bears: Know when the world is too much, create cozy, calm spaces
🐙 Octopuses: Adaptable, embrace many ways of thinking, connect lots of ideas

Your animal isn't your "problem"—it's your superpower, your way of seeing the world that others might miss.

# ⚔️ Roles = How You Want to Help (No One's Stuck in Just One!)

🧙 Mages: Research and discover, turn findings into practical wisdom
⚔️ Warriors: Build and fix, turn ideas into working tools that protect users
📜 Sages: Write and explain, keep knowledge alive and accessible
🎨 Artisans: Design beautiful, usable experiences
🏹 Rangers: Explore and test, report what works in the wild
💚 Healers: Care for people, keep spaces kind, help when things get rough

Mix, match, switch roles, or invent new ones. This is your journey.

The more you take care of yourself, and more adventures means your pet gets more happier :>

So if anyone is interested, choose your pet and join us on the shore,
let's build sandcastles together <3

But either way, please be kind to yourselves and take good rest, okay??

Ps. We are an open source community,, we have wide range of contribution types from sharing your own experiences, research, code, designing, to documentation - So if you are interested, you are very welcome to join us :>

Traceprompt - open-source SDK for tamper-proof LLM audit trails

Hi!

I’m Paul, founder of Traceprompt. We’re building an open-source SDK that wraps your LLM calls and generates tamper-proof audit trails, so you can prove who did what, when and with which model.

You can check out the Node SDK (more languages coming soon): https://github.com/traceprompt/traceprompt-node

We built Traceprompt because LLMs are being used everywhere without a clear plan for audit and compliance. From research and discussions with other devs, I often see fintech and healthcare teams manually stitching together API Gateway, CloudWatch Logs and S3 buckets to track prompts/responses and retention. This is both complex and costly as there's little to no proof of immutability. Most current tools (Langfuse, Heliclone etc.) focus on LLM observability; few help generate verifiable evidence for compliance. That’s where we come in.

To add, regulations are also moving in this direction (e.g. the EU AI Act requires logging for certain high-risk systems, HIPAA calls for audit controls and FINRA/SEC rules push WORM-style retention). The goal is to make “prove nothing changed” boring.

Our SDK is simple:

1. BYOK architecture with AWS KMS. We never see plaintext prompts/responses; only you can decrypt. Other KMS providers are on the roadmap.
2. Append-only, hash-chained logs with a public Merkle anchor for independent verification. Repo: https://github.com/traceprompt/open-anchors
3. Audit packs: export CSV rows + proofs (and receipts) when someone asks “what exactly happened on this day and time.” You can also verify the audit packs — if a single byte was altered or a row removed by a bad actor, verification fails.

If "AI audit trails" are on your mind or on your roadmap, I'd love to talk. Please do checkout the repos: review code, install the SDK and experiment; open issues if anything breaks

1. https://github.com/traceprompt/traceprompt-node
2. https://github.com/traceprompt/open-anchors

We'd love to hear your feedback, so we'll be in the comments! If you're a dev, I am happy to dive into more technical details or answer any questions. If you're in the AI audit and compliance space, please do get in touch as we have lots to learn and uncover :)

Thank you!

Looking to help test

I want to be completely transparent in saying I did recently graduate a boot camp and with that being said I’m looking for open source projects that preferably have a couple testers helping already, my goal is to both gain experience testing fully on my own but also collaborating with others as I don’t have much experience making full test suites myself.

16 y/o team here – we open-sourced our AI project after 10 months of work. How do you grow a community?

Hey all,
We’re a small group of teenagers from Turkey who spent the last 10 months coding an AI app in our free time. We open-sourced it under Apache 2.0 because we wanted to share and learn with the community.

We’ve just started sharing it around, but we’d really love advice: how do early open-source projects attract contributors and keep momentum? Any tips from your own experience would mean a lot.

BuckleVibes: Convert Your Favorite MechVibes Soundpacks to Bucklespring

If you've ever used MechVibes, you've probably noticed it can have some pain points, like input delay. I've found that bucklespring is much more responsive, but it's limited to just one sound.

BuckleVibes is a simple Python noscript that takes a MechVibes V1 soundpack and automatically converts it into a folder of individual .wav files, ready to be used by bucklespring.

The project is available on GitHub: https://github.com/p-febis/bucklevibes

You'll find installation instructions and usage examples in the README. You'll need Python and FFmpeg installed.

I'd love for you to try it out and let me know what you think! Feedback, bug reports, etc. are welcome.

Any open source MMO or other projects looking for volunteer GMs or community support?

Hey all,

I’ve recently started volunteering with ChromieCraft (a World of Warcraft Wrath project) and I’m really enjoying helping with community support, bug triaging, and suggestions. It got me thinking:

Are there other open source MMO style projects (or game servers) that are looking for beginner friendly volunteers?

I’m especially interested in roles like:

GM / player support
Community moderation
Testing / bug triaging
Writing guides or doing outreach

I know about projects like ChromieCraft, WorldForge, and Multiverse, but I’d love to hear if anyone here knows other communities that welcome new contributors.

Thanks in advance!

🎯 I built tools I needed — now I'm sharing with all

Hey folks,

Over the last few months, I found myself constantly pausing to solve the same annoying problems while coding — the kind of things that slow you down but never feel big enough to warrant a full-blown tool. So... I built them. And now I’m sharing them for free, in case they help you too.

1. 🖼 vscode-screenshotify

Ever needed to share a clean snippet of code on Twitter or in docs?

I was tired of switching to Carbon or clunky browser extensions, so I made this extension right inside VS Code.

One click → beautiful screenshot of your code. Zero config, super light.


2. 🔄 dhara

I find it super frustrating that in 2025 I need to juggle btwn different techniques just to send files to my pc to phone or from phone to desktop. Either mail, or telegram or any other 3rd-party site that stores your file to their cloud.

Hence, I made a CLI tool that solves this with just quick QR code scan you can send, recieve with just a command. Modern solution for Modern folks.


And because I apparently hate free time, I’ve started building something new:

3. 🔥 An open-source heatmap CDN for frontend devs
It’ll be a plug-and-play noscript you drop into your HTML. No tracking creepiness, no selling data. Just a lightweight way to see where users are clicking and how they’re interacting with your frontend — perfect for indie devs or small teams without $$$ for Hotjar.




---

These projects are totally open source, no paid tiers, no BS. I'm just a dev scratching my own itch and hoping it helps others too. If any of this sounds useful, I’d love feedback, PRs, or ideas!


Let me know if you’d use the heatmap tool — trying to gauge whether to open that up early 🙌

Cheers!
