I'm not sure i understand the benefits of blockchain here...though if they can pull off the mesh aspect of this, then that's really awesome. I wonder though, if the constant "peer hopping" (via bluetooth) won't drain the batteries of mobiles? Then again, if a mesh-like network takes off, maybe antennas can be tuned not to "catch" signals from far off cell towers but rather the next closest mobile...which might require less power? This is not my expertise, so will defer to other experts...Well, i'll say that the idea sounded cool on the Silicon Vallet show, and it still sounds cool in real life...assuming they can pull it off.
