The best Sundays are for long reads and deep conversations. Recently the hosts of the Let's Talk Bitcoin! Show were joined by Richard Myers to discuss the current state of mesh networks and how Bitcoin's Lightning may be the missing ingredient to their success.
On today's episode of Let's Talk Bitcoin! you're invited to join Andreas M. Antonopoulos, Adam B. Levine, Stephanie Murphy 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 Bitcoin's Lightning Network.
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 low-power networks that'll let your phone send text messages or even bitcoin micro-transactions, even in areas with no coverage.
According to Myers, Bitcoin's Lightning Network is what's needed to make mobile mesh networks catch on by bootstrapping on top of the payment routing infrastructure.
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 Myers 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 ca ustom 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 internet and that's very important because you lose a lot of privacy ... you lose all your privacy ... if you were to just send messages over the internet without onion routing.
We're sending over more or less a physical TOR network since it's going from node to node, not through a central ISP who can associate who you're trying to pay. We're also doing it over a low bandwidth network, so if you were sending 1300 bytes it may not sound like much in the age of the internet but we're talking about devices that [have a maximum data transmission capacity of] about a kilobyte a minute so that's a significant amount of the bandwidth that you have [tied up just in the web's onion routing]
So, for example with LOT49, we take out the onion and we use the native routing at the mesh device [level] which is optimized for mesh communications. And there are a few other little changes we make like that in order to reduce the bandwidth by chunking up messages. ... The ultimate goal is to minimize the Lightning protocol overhead so that there is more bandwidth available for data ... for things like sending an SMS and as bandwidth increases there may be things like internet protocol."
