As AI-generated content floods publishing submissions, Dylan Reed's service addresses a real friction point for literary gatekeepers: establishing provenance that a manuscript came from human hands, not an LLM training run. The cryptographic seal won't solve the underlying problem—good AI writing is becoming indistinguishable from mediocre human writing—but it exposes where the market is actually breaking. Publishers aren't investing in detection; they're investing in certification. Human authorship is becoming a verifiable credential. When a foundational signal of quality collapses, the market builds infrastructure around proof instead.
