I was looking at the canaries, and I liked the idea of a proof of freshness with the latest news headlines. While people can't create canaries ahead of time, it is possible to conspire to modify or backdate one of them after they have been published. To prevent this, we could use a blockchain-based timestamp, where the hashes of each canary are placed within the blockchain of a powerful cryptocurrency. Something similar to these services:
