LTB #438 Bootstrapping Mobile Mesh Networks with Bitcoin Lightning

On today’s episode of Let’s Talk Bitcoin! you’re invited to join Andreas M. Antonopoulos, Adam B. Levine, Stephanie Murpy and special guest Richard Myers for an in-depth look at the past, present and future of ‘Mobile Mesh Networking’ technology and the open source LOT49 protocol built on top of lightning. Just as cryptocurrencies like Bitcoin don’t rely on static infrastructure and professional providers, mobile mesh networking allows the creation of inexpensive, high range, low bandwidth and power consumption ad-hoc networks that’ll let your phone send text messages or even bitcoin lightning network micro-transactions, even in areas with no coverage. According to Richard, Bitcoin’s Lightning is a what’s needed to make mobile mesh networks catch on by bootstrapping on top of the payment routing infrastructure. “…the Lightning network currently sends payments from A to B to C and then all those intermediate nodes can connect a small fee if the payment is delivered at the end. All we’re doing is saying ‘Not only [can you send] a payment, but [you can send] a small message. In our case it’d be a SMS message. So you’re sending an SMS message along with a Lightning payment from A to B to C to D, and when D receives that message they return proof that it was delivered and that’s what flows back through the network. In the Lightning sense, that’s your pre-image. It’s computed from the message, that’s how the nodes are able to collect payment even if they lose touch with the original person who sent it.” But the way the Lightning network uses data natively isn’t ideal for mobile mesh. The open source Lot49 protocol is another layer on top of lightning that Richard says is necessary to make it work at scale while using mesh devices as an extremely low-bandwidth TOR-like privacy layer. “In many ways we’re not making a new protocol, we’re literally using lightning. Lot49 is custom communication protocol that’s optimized for mesh. For example, right now there’s a 1300 byte onion that’s used to route messages over the i
