Samourai and goTenna Enable Bitcoin Transactions Without Internet …

Samourai Wallet is collaborating with goTenna, a Brooklyn-based company specializing in off-grid communications, to produce txTenna, an Android app that combines mesh networking with Bitcoin transactions. The app will allow users to pair their phones with goTenna’s portable antennas in order to broadcast transactions.

goTenna produces consumer-grade hardware to facilitate mesh networking — a concept that echoes much of the decentralization ethos that we see across the cryptocurrency domain — which operates by allowing peers to connect directly to one another for the purpose of routing packets, sidestepping the need to rely on an ISP or cell tower.

What will happen when providers decide to crank up prices just because they can?” said Rich Myers, goTenna’s Decentralized Applications Engineer.

“Mesh networks are the only legitimate alternative to these traditional centralized communication networks. They are completely decentralized and democratized, leaving the power of communication in the hands of the people. Beyond that, they are much more resilient to unforeseen disasters — the only thing these networks need to function is a mesh networking device paired with a smartphone.”

For its part, Samourai Wallet has been focusing on censorship resistance and privacy-oriented tools since it began in 2015. With features such as direct interaction with trusted nodes, added hops to circumvent chain analysis, and SMS commands for remotely wiping wallets, it has seen widespread adoption by users wishing to incorporate an additional level of privacy into their Bitcoin transactions.

Samourai has been curating Mule.tools, an R&D initiative to further reinforce the censorship-resistant properties of the Bitcoin blockchain and also published the code for Pony Direct, a proof-of-concept app for broadcasting transactions over SMS in January.

“We believe one of the most fundamental…
