TFA Labs (IoT-SAS) was a legitimate attempt at blockchain-based IoT security, securing a notable U.S. Department of Energy grant (~$200k) in 2019. However, the project currently appears inactive ('deadpooled' on market intelligence platforms), and the provided website is offline. The submission contains critical credibility issues, specifically the claim that 'most people have used my product' (false for a niche B2B grid security tool) and an ambiguous 'marketcap' figure. While the technical concept of signing data at the hardware source is valid, the project lacks current utility, active users, or market relevance.
