Tagger (@TaggerAI): Every internet protocol upgrade follows the same script: communication opens, trust gets claimed.

Every internet protocol upgrade follows the same script: communication opens, trust gets claimed. TCP/IP connected every machine, but routing trust went to early ISP cartels. HTTPS certificates went to a handful of authorities. OAuth handed the login layer to Google and Facebook. Communication protocols belong to everyone. The trust layer belongs to whoever builds it first. In November 2024, Anthropic open-sourced MCP. In 2025, Google released A2A. Within a year, every major agent framework had integrated them. The communication layer was written. But the trust layer is still blank. How does an agent prove its training data is licensed? How do agents trust each other's outputs? How does reputation travel across networks? Once data has been used, how is it traced? There is no infrastructure today that answers these questions. Tagger is building that layer. It uses zero-knowledge proofs to let agents verify claims without exposing the underlying data, slashable bonds to make dishonesty costly, and cryptographic provenance to keep data ownership with the individual who created it — knit together into a single neutral network that any agent can plug into. This is HTTPS for the agent era.
