Key Takeaways:

By eliminating one of the largest dependencies of Bitcoin the internet, Jack Dorsey is taking Bitcoin to an even greater level of reality. His new application, Bitchat demonstrates how Bitcoin transactions are possible even in the event of traditional connectivity loss.

Bitchat is akin to a messaging application but the key innovation lies squarely in the crypto. The application can even be used to make and sign Bitcoin transactions without Wi-Fi or mobile data. The transactions are then transferred amongst phones via Bluetooth till they reach an electronic device that can send them to the Bitcoin network.

Such a design preserves the fundamental rules of Bitcoin. It has no new chain, no alternative consensus, and no custodial layer. The users retain their own private keys and transactions are still made on the primary network of Bitcoin. Bitchat only changes how transaction data travels.

For Bitcoin advocates, that distinction matters. Offline transaction relay has long been discussed in theory, especially for use during network outages, natural disasters, or in regions with restricted connectivity. Bitchat turns that theory into a working prototype on consumer smartphones.

Bitchat relies on Bluetooth Low Energy (BLE) mesh networking to move transaction data across short distances. Standard Bluetooth connections are limited in range, but mesh networks extend that range by allowing devices to relay information automatically.

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.
