My point is those points aren't exactly "Key features" or outstanding compared with today's offline signing.

I appreciate your honest feedback — and I understand your hesitation.

I agree: most so-called "offline crypto" solutions today just mean signing on one device and broadcasting later via QR or USB. What I’m working on includes the full peer-to-peer transmission layer — without using traditional proximity-based channels like Bluetooth, NFC, or LoRa. And yes, the distance is global — not just short-range.

I said "offline signing", not "offline crypto" which usually refer to different thing.

because i had done tests now guys you can check this my first offline transaction with proof i send 3000 satoshis

I completed a full crypto transaction — from device to chain — with no connection, no data, no internet, and no infrastructure. It’s real. And it works.

✅ Transaction broadcasted successfully!
📨 TXID: {'txid': '501789e689cea0c90e1c18954811ad355c93b65032f107c8eeba6fed61ca50a2', 'response_dict': '501789e689cea0c90e1c18954811ad355c93b65032f107c8eeba6fed61ca50a2'}

TX data doesn't even contain information about how the TX is created or transmitted, so nobody can verify your statement.

Thanks for the reply — I appreciate the healthy skepticism and the distinctions you've made.

You're absolutely right that a Bitcoin transaction by itself (in hex or base64) contains no metadata about how it was created, signed, or transmitted. From a blockchain explorer’s perspective, my transaction looks no different than any other valid testnet TX. That’s by design.

But what makes this project different is precisely what you can’t see in the TX:

It’s how the transaction was formed and delivered from an entirely offline device to the mempool — with no QR code, no Wi-Fi, no Bluetooth, and no NFC.

I’m not claiming “offline signing” in the usual sense — I’m referring to a complete offline-to-online bridge, where the sender device is airgapped and unconnected, yet the TX reaches the Bitcoin network almost instantly.

This is not a whitepaper or a mockup. The TX was created, signed, transmitted, and broadcast — successfully. I’ve done this multiple times now on Bitcoin testnet.

Of course, I’m not sharing the full method publicly (yet) for obvious IP and security reasons. But the result is real and reproducible. It opens doors for:

Crypto access in regions with no data infrastructure

Emergency communications where internet is down

Bypassing local restrictions or censorship

If this were just another QR-based cold wallet flow, there’d be nothing new. But I believe this introduces a novel layer — a “silent carrier” for crypto transactions — without relying on traditional connectivity at all.

Thanks again for engaging. This kind of dialogue helps sharpen the conversation around what’s possible.
