Boneh, Bonneau, B{\"u}nz, and Fisch (CRYPTO 2018) recently introduced the notion of a \emph{verifiable delay function} (VDF). VDFs are functions that take a long \emph{sequential} time TT to compute, ...

A Verifiable Delay Function (VDF) is a function that takes at least TT sequential steps to evaluate and produces a unique output that can be verified efficiently, in time essentially independent of TT...

We introduce the notion of a continuous verifiable delay functioncontinuous verifiable delay function (cVDF): a function gg which is (a) iteratively sequential---meaning that evaluating the iteration ...

2019/3/1
We present the first treatment of non-interactive publicly-verifiable timestamping schemes in the Universal Composability framework. Similar to a simple construction by Mahmoody et al., we use non-par...

2019/3/1
Using the idea behind the recently proposed isogeny- and paring-based verifiable delay function (VDF) by De Feo, Masson, Petit and Sanso, we construct an isogeny-based VDF without the use of pairings....

We study the problem of building a verifiable delay function (VDF). A VDF requires a specified number of sequential steps to evaluate, yet produces a unique output that can be efficiently and publicly...
