Protocol Stack Position
Asset / Value Embedding None — tinySSB is an academic research protocol for constrained (BLE/LoRa) mesh environments with no token or economic layer. Resource sharing is purely cooperative/volunteer.
Protocol Maturity / Standardization Academic / Research (university research project from University of Basel; published academic papers; builds on SSB protocol family)
