# LNTenna - [[TxTenna]] but over [[Lightning]] - Uses [[Blockstream Satellite]] to transmit messages between - Github: https://github.com/willcl-ark/lntenna-python # LNTenna-Python Blog Series By Will Clark for[[In The Mesh Blog]] Sep 19 2019 ## Part 1: Submarine Swaps over Mesh https://inthemesh.com/archive/lntenna-python-part-1/ The goTenna mesh networking platform already allows [goTenna Mesh](https://gotennamesh.com/products/mesh) devices connected to it to share GPS locations and text messages with other users within the mesh. And, if one or more of those mesh users has an internet connection, then they can act as a gateway and pass messages to and from the mesh network, to anyone in the world. goTenna has released a software development kit which allows developers to program their own features on top of the device. One notable innovation in relation to bitcoin payments, the [txTenna](https://txtenna.com/) project allows you to run a full bitcoin node, with send and receive capabilities, from a device with no direct internet connection. This project utilised the [[Blockstream Satellite]] which broadcasts the bitcoin blockchain from a satellite. We wanted to expand on this idea, of censorship-resistant, private and secure payments and message-sending capability over the goTenna mesh network. Because broadcasting of the bitcoin blockchain via satellite does not consume all the available bandwidth, [[Blockstream]] has also enabled arbitrary [message transmissions](https://blockstream.com/satellite-queue/), also broadcast over the same frequencies and able to be received and interpreted by those using their satellite downlink. ## Part 2: Direct Payment Negotiation over Mesh https://inthemesh.com/archive/lntenna-python/ ## Part 3: LNProxy https://inthemesh.com/archive/lntenna-python-3/
