“How to Build Time-Lock Encryption” by Jager

“Time-release Protocol from Bitcoin and Witness Encryption for SAT” by Liu, Garcia, and Ryan

I looked through the references, googled, searched GitHub but couldn't find an implementation of either of them in any programming language.

Are these theoretical with no implementation yet?

I would greatly appreciate a link to an implementation if one exists.

Tibor Jager (author to the first paper linked in question):

"There is no implementation yet. Given that there are no really efficient Witness Encryption schemes yet, the construction so far is rather theoretical."

  • $\begingroup$ Is this scheme also can't be implemented by the witness encryption which based on the indistinguishable obfuscation?If the multilinear based witness encryption can't provide the efficient required for the time-lock encryption. $\endgroup$ – Oiiiwk May 30 '19 at 14:46
