The FCC Should Use Blockchain to Manage Wireless Spectrum

[Commentary] Instead of having a centralized database to support shared access in specific spectrum bands, innovators should explore the use of blockchain as a lower-cost alternative. If the effort succeeds, the benefits could be considerable: The system could reduce the administrative expense of allocating spectrum and increase efficiency by enabling demand-matching spectrum sharing and by lowering transaction costs. Even better, the public quality of the information on the blockchain could expose patterns in use and inspire new technical innovation in the process. Plus, new models for short-term leasing of our airwaves could emerge and expand the range of wireless uses. While the extent of the blockchain's (much-hyped) utility is uncertain, the cases that are most compelling are ones where a broad array of users need to establish a system of trust to facilitate an exchange in value. Spectrum sharing fits that model perfectly. That may seem out there, but then again, there was a time when the app store was a small place, rather than a megamarket filled with anything and everything. So let’s consider how blockchain can help remake spectrum access. The possibilities are real, and the potential to power a new and more efficient wireless world is worth the exploration and effort.
