Kosher Trust

A PKI so rabbis can sign websites as kosher, and every browser can verify.

Overview

Kosher Trust is a rabbinic Public Key Infrastructure. A rabbi signs a domain (Ed25519, scoped, time-bound) and publishes the signature to an append-only registry. The browser verifies on each load and shows a visible badge. Pluralistic — every rabbi owns their own chain, every user chooses which chains to trust. Contract 10 of the kosher stack.

Next stage

Where this is heading.

v0 single-CA proof of concept, v1 multi-CA public registry so any rabbi can join, v2 blockchain-anchored append-only log for tamper-evidence. Real rollout depends on rabbinic onboarding — contract 10 is drafted, execution waits.
