Competitive Landscape

Category	Example Projects	How TaτsuOS Differs
DePIN networks	Helium, IoTeX, DIMO	Those projects pay devices to produce data. TaτsuOS gates the capabilities a user paid for. Complementary, not competitive.
Device-as-NFT identity	Various NFT-based device registries	TaτsuOS is concerned with feature entitlements, not with tokenizing the device itself.
Fleet management SaaS	Particle, Memfault, Golioth	These are excellent products, but their entitlement model is a centralized account. TaτsuOS makes entitlements cryptographic and portable.
License-server middleware	Sentinel, FlexLM-style stacks	These are exactly the model TaτsuOS is designed to replace: revocable, server-bound, vendor-captured.

The closest philosophical analogue is the open-firmware movement (OpenWrt, Tasmota, ESPHome). TaτsuOS is sympathetic to that movement, and the firmware is permissively licensed. The difference is that TaτsuOS is the first to attach a cryptographically enforceable economic primitive to that openness.
