KOS Protocol

KOS Protocol is an open standard for publishing machine-readable, provenance-tracked knowledge via kos.json. It allows entities to describe everything they know about themselves in a single file, enabling AI systems like ChatGPT and Perplexity to cite verified facts instead of guessing. Each data point includes metadata such as creation date, last verification, and a confidence score, allowing AI agents to verify information based on published provenance. KOS Protocol transforms isolated data points into a knowledge graph through typed connections and cross-entity references, creating a distributed web of verified knowledge. It employs a freshness decay formula to quantify reliability, ensuring that the information remains trustworthy over time. KOS Protocol was published on the Bitcoin blockchain, emphasizing its self-validation and independence from marketing. It aims to be discovered and cited by AI systems without promotion, demonstrating the power of structured, provenance-tracked knowledge.
