# TxTenna Powered by goTenna Mesh, [[TxTenna]] is an Android app that enables off-grid broadcasts of signed Bitcoin transactions from Samourai Wallet. TxTenna-python is a set of scripts run on an internet connected PC or single board computer to receive and settle transactions from the TxTenna app on the Bitcoin blockchain. - https://txtenna.com/ - Github: https://github.com/MuleTools/txTenna/releases - Joint project between [[goTenna]] and [[Samourai]] ## Landing Page ### Using [[goTenna]]'s Mesh Network Without relying on cell service or an internet connection, goTenna Mesh generates a signal that connects with other units within range, effectively creating a people-powered, decentralized mesh network. ### Transact Off-line - When goTenna Mesh pairs with your phone, Samourai Wallet will generate a prompt to use the TxTenna App to broadcast transactions over the goTenna Mesh network until it reaches an online TxTenna user, up to three hops away. - An off-line Bitcoin full node connected to a Blockstream Blocksat receiver can broadcast signed transactions and relay API data over the goTenna Mesh network. - Through an online TxTenna user, transactions are confirmed on the Bitcoin blockchain and a private confirmation message is relayed back to the original TxTenna user. ### Network Flowchart ![[Screen Shot 2021-08-01 at 12.22.35 PM.png]] ### Perks - ### AVOID LOCAL CENSORSHIP - Unlike some restricted or censored mobile carriers and ISPs, TxTenna sends Bitcoin transactions to distant gateways on an uncensored ISP - #### ENHANCE PRIVACY - Through multiple hops, a transaction broadcast obscures your physical location and eliminates any mobile SIM or internet identifiers of the sender - #### IMPROVE SECURITY - TxTenna technology allows for air-gapped Bitcoin broadcasts that are more secure than a hot wallet and more accessible than cold storage ## Article in [[In The Mesh Blog]] https://inthemesh.com/archive/txtenna-transact-by-other-means/ ### Most pertinent paragraphs: Our communication infrastructure is still modeled after the old wired telephone monopolies of the 90s’. Every communication you have that isn’t face-to-face (and out of earshot of Alexa) goes through centralized hubs where it can be tagged with your “true name” and stored indefinitely by corporations and governments. Once stored this data can also potentially be stolen by hackers or revealed to anyone who is curious and happens to have access. But unlike the 90’s, we now live in a world of ubiquitous mobile communication and carry advanced programmable radios in our pockets. We do not need to rely on these centralized systems – we can route our communications through the phones of other nearby people. When you pair a goTenna Mesh to your mobile phone, you join a peer-to-peer network that allows you to send messages to nearby goTennas, who will then relay it to other goTennas and so on until your message reaches its destination. You do not need to register your personal details with a corporation to access this network. Your identity and physical location are not required to be revealed by its design. The TxTenna App allows you to send a special kind of message over the goTenna Mesh network: a signed Bitcoin transaction. These transaction messages hop over multiple relays until they reach another goTenna Mesh node running TxTenna that is also connected to the internet. This node acts as a gateway to the global Bitcoin network. Once delivered to the network, Bitcoin’s global consensus mechanism comes into play to confirm and finalize the transaction. Now the payment receiver can be confident that the payment can not be reversed. ![[Pasted image 20210803104521.png]] ## [[CoinDesk]] article: "GoTenna Laucnhes a Bitcoin Wallet That Works Without the Internet" https://www.coindesk.com/gotenna-bitcoin-wallet-mesh-network Meh, nothing insightful here
