Audit of drand Timelock Encryption
The Drand team at Protocol Labs recently released a timelock encryption based on the Drand threshold network run by the League of entropy. This timelock encryption construction ensures a ciphertext will be decryptable only after some specified time has
passed and not before. The cryptographic construction of the timelock encryption was recently presented in depth during the Real World Cryptography conference.
