🎯 BITCOIN VIA BLUETOOTH WITH BITCHAT: NO NETWORK REQUIRED 🎯
Callebtc has demonstrated a revolutionary innovation: sending Bitcoin (via Cashu e-cash) from Android to iPhone via Bluetooth using Bitchat, without internet on the sender side.
It's an instant, private, offline peer-to-peer transfer, like passing digital cash hand to hand.
Bitchat is a cross-platform meshnet app (Android/iOS) that creates Bluetooth networks for chat and payments. It natively integrates a Cashu wallet: an open-source protocol for e-cash on Bitcoin/Lightning, generating cryptographic tokens (IOUs of Bitcoin) spendable offline. The sender transmits the tokens via Bluetooth; the receiver redeems them later at the mint (custodial issuer) by connecting online, preventing double-spending through Chaumian mechanisms.
No central server, low latency, ideal for areas without coverage (festivals, emergencies, censorship).
It works in multi-hop mesh: only one online device is needed for validation.
Risks?
Custody at the mint (reputational trust) and loss of device before redemption, but tokens can be recovered via seed.
Live demo from Bitcoin Amsterdam 2025 shows smooth transactions, a future for cash-like payments on BTC.
This surpasses fragile infrastructures, making Bitcoin truly unstoppable and private.
Next step: NFC payments?

The interesting story behind the Bluetooth logo, which combines history and Nordic symbolism. 🤯
Few know this, but the symbol that connects your phone and headphones was born over a thousand years ago, during the Viking era. 😱
Its name comes from Harald “Bluetooth” Gormsson, the Danish king of the 10th century who unified Denmark and Norway under one crown. His nickname, “Blue Tooth,” appears in medieval chronicles and would refer to a very dark or bluish tooth, perhaps due to an infection or simply natural coloration.
The emblem of the technology is not a coincidence: the Bluetooth logo combines two ancient Nordic runes, ᚼ (Hagall = H) and ᛒ (Bjarkan = B), the initials of Harald Bluetooth, intertwined as a single figure.
Thus, every time you activate Bluetooth on your device, you are using a Viking symbol that represents exactly what that king achieved centuries ago: uniting what was separated. ⚡️🌍
