The absence of internet connectivity has long been a roadblock for Bitcoin transactions. Whether caused by natural disasters or unreliable infrastructure in certain regions, the lack of internet means that digital payments via cryptocurrencies like Bitcoin are rendered impossible.

A recent research paper, however, offers a potential solution to this predicament through the use of localized "mesh networks."

Researchers from Florida International University specializing in post-disaster technology have developed a way to facilitate Bitcoin payments offline, utilizing the Lightning Network—a faster, more cost-efficient layer atop the Bitcoin blockchain. Dubbed LNMesh, this concept employs localized mesh networks wherein nodes are directly connected through Bluetooth and WiFi, rather than …
