Fun Ecash App feature that I'm working on: NFC plus Bluetooth low energy transfer of ecash notes

Originally @EricSirion's idea, essentially the app uses NFC to exchange public keys, encrypts the notes and broadcasts them Bitchat style via bluetooth

Use two browsers

One for daily use, one for research you don’t want linked to your identity

Never cross-contaminate

Your messages. Your Bitcoin. Together, at last.

Radar brings private messaging and self-custodial Bitcoin Lightning together in one seamless experience, and because it's built on Signal's incredible network - the people you already talk to come with you.

Paper note designs aren't hardcoded.

Each template lives in a Git repository and is described using metadata that defines things like:
👉 QR placement
👉 Safe print regions
👉 Layout rules
👉 Optional creator donation address

Anyone can contribute new note designs through a PR.

[Harsh Dev Pathak @Harsh_dev098]

As a @bitshala_org fellow, have build a PaperEcash, a web based paper ecash issuance system built on top of @fedimint

The goal is to make issuing printable ecash notes as easy as generating a PDF.

The flow is as:

[Harsh Dev Pathak @Harsh_dev098]

Paper Ecash lets you reopen an issuance session, verify the redemption status of every note against the federation, and reclaim(for 24 hour window) only the notes that remain unspent.

Working with uncensored models, even when less capable than frontier ones, is so freeing 😌

GLM 5.2 is already a step up from GPT and Opus, but truly uncensored feels even better. No dancing around what I want the model to do, no preaching about why it would be unethical to help me find exploits etc.

If we want AI to be a freedom technology it has to be open, uncensored models running locally or at least in trusted computing environments (TEE) so inference providers can't spy.

I've been working on potential escrow module for @fedimint that enables:
👉 Buyer/Seller escrow contracts
👉 Federation enforces contract rules and signature verification
👉 Arbiter assisted dispute resolution
👉 Trust-minimized fund custody through federations

how it works: ...

[Harsh Dev Pathak @Harsh_dev098]

If a dispute occurs:
👉 Funds remain locked
👉 Evidence is reviewed off-chain
👉 The designated arbiter decides the outcome
👉 The federation verifies the arbiter's signature and enforces the result

The federation enforces the contract but never knows the participants identities

@mechanakamoto Stop thinking of Bitcoin as an 'investment'. Bitcoin isn't a tool for getting rich. It's a tool for freedom. Freedom isn't always easy.
But on the plus side, the less people thinking of it as an 'investment', the less volatility there'll be. So the problem fixes itself in time.

A powerful reminder from @PastorEvanLive and @gladstein at @TheBitcoinConf:

The modern world runs on open-source software maintained by people most will never know.

From privacy tools to Bitcoin infrastructure, freedom survives because builders keep showing up quietly, day after day.

Respect to every FOSS contributor keeping the signal alive. 🙇🧡

India runs on UPI, which is a payment network connecting over 500 million consumers and 65 million merchants.

To pay, you simply scan a QR code at the counter.

With the 256D Mini App on Fedi, you can now do the same with bitcoin. Scan the UPI QR code, pay from your Fedi wallet, and the merchant receives rupees.
