A notarized BCH/USD price feed on Bitcoin Cash. Thirteen notaries, each pinned to one exchange, fetch it over TLS every minute, verify its certificate, and sign the price they saw. A covenant checks those signatures, takes the lower median, and writes it on chain together with how many rows signed. Once a minute, in one transaction.

Nobody in the system chooses a number, and nobody chooses a trust level for you. The chain accepts a minute once seven rows signed it; the commitment says whether seven signed or thirteen. A minute signed by all thirteen takes seven colluding keys to forge; a minute signed by seven takes four, and it says so. A consumer contract reads that byte and sets its own bar. Anyone can post the update. No admin keys, no clock in the covenant.

Today ticker.cash operates all thirteen rows, so the honest description is one operator who cryptographically verified each exchange. A row is one small binary and one exchange endpoint, built to be handed to independent operators; a majority of rows can add or replace rows without a new deployment. The stats page names the operator of every row.

Read the price on chain. Spend a Ticker NFT in your transaction and decode its 17-byte commitment: a standard oracle price message (timestamp, sequence, price in cents) followed by the number of rows behind it. Integration guide, covenant walkthrough, and how to run a notary in the docs.
