From another comment: “Besides calculating verifiably random numbers, the computers will also decrypt content for anyone if you send it content encrypted to their public keys and the encrypted content contains a time range that includes the present.” That sounds like decryption would fail when the present time is after the specified time range.

Yeah, that's not exactly how it works. The drand nodes are publishing random beacons that are signed, that's the only thing the networks does. Publishing public verifiable randomness. But pairing-based cryptography allows us to do identity-based encryption and that's like magic, but basically we can rely on a message as a public key, and on a signature as a secret key, and that's how tlock works.
