There's an interesting bit about being unable to recover the timelocked secret if the parties that keep the network going disband before the release date:

    *if the League of Entropy shuts down, members will delete their keys*

    The world is unpredictable (just like drand randomness... heh), and it's possible that the League of Entropy will all hang up their coats at some point in the future. Should that happen, members would have two choices with their private keys: release them to the world or delete them entirely. The former would mean that ciphertexts created for some time after the cessation of the network would be decryptable to everybody. The latter would mean that ciphertexts created for some time after the cessation of the network would be unencryptable forever (/until quantum computers can break them). In the interests of privacy, we felt the latter option was preferable. That said, if you encrypt the private key to your [insert cryptocurrency name] fortune to stop yourself from spending it now and the network stops... you're going to have a bad time.
