Jack Dorsey Unveils Bitchat, Enabling Bitcoin Transfers Without Internet via Bluetooth Mesh
Key Takeaways:Bitchat Focuses on Sending Bitcoin, Not Just MessagingHow Bluetooth Mesh Networks Carry Bitcoin DataFrom Local Signing to Network Broadcast
A user signs a Bitcoin transaction on their device. The resultant signed data packet is subsequently transmitted by Bluetooth with other users nearby who are running Bitchat. The devices are used as relays and the transaction is furthered until it arrives at a phone that has access to the internet.
After being connected, the transaction is relayed to the Bitcoin network as any other transaction. Until that time it is an unproven fact but still valid. This approach avoids the need for centralized servers or trusted intermediaries during the relay process.
Dorsey claims the mesh can extend effective range to around 300 meters via multiple hops. Though this range is still limited, it shows that Bitcoin transaction can be moved locally without telecomunication infrastructure.
