Kadupul: Livin' on the Edge with Virtual Currencies and Time-Locked Puzzles / May 2015
Workshop paper on DIY networking using timelock puzzles, presented at the DIY Networking workshop with Magnus Skjegstad and Jon Crowcroft. Kadupul explored using virtual currencies like Bitcoin to incentivize heterogeneous multihop mesh networking. The key insight was using time-locked puzzles where forwarding nodes compete to solve cryptographic challenges, with the fastest delivery claiming a reward. This created a natural surge pricing model during congestion and could enable low-latency services like video streaming and AR on mesh networks.
