Pastepile — time-capsule pastes
Send a message to the future. Pick an unlock date, and the paste stays cryptographically sealed until that moment - not even Pastepile can open it early.
How the seal works
Time-capsule pastes use drand, a public threshold network that produces a verifiable random beacon on a schedule. The paste is encrypted to the beacon round that will be published at your chosen unlock time. The decryption material literally does not exist yet, so nobody can decrypt early - not the recipient, not Pastepile, not an attacker who steals our database.
When the round is published, anyone holding the link can decrypt.
Good uses
- Birthday or anniversary messages set months in advance.
- Embargoed announcements that must not leak.
- "Open in 10 years" notes to yourself.
