Has Burdges and De Feo's concept of Delayed Encryption ever been implemented? In mid 2020 Jeffrey Burdges and Luca De Feo published a paper proposing a trapdoor-less time-lock puzzle called Delay Encryption. Has a prototype of this ever been made?
There is PoC code for the De Feo-Masson-Petit-Sanso VDF here: https://github.com/isogenies-vdf/isogenies-vdf-sage. It's easily adapted to Delay Encryption.
