A Note on the (Im)possibility of Verifiable Delay Functions in the Random Oracle Model
Verifiable Delay Functions Random Oracle Model
2019/6/6
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...

2019/6/4
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 ...
Non-interactive Cryptographic Timestamping based on Verifiable Delay Functions
non-interactive cryptographic timestamping universal composability verifiable delay functions
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...
A note on isogeny-based hybrid verifiable delay functions

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 present two new Verifiable Delay Functions (VDF) based on assumptions from elliptic curve cryptography. We discuss both the advantages and some drawbacks of our constructions, we study their securi...
A verifiable delay function (VDF) is an important tool used for adding delay in decentralized applications. This short note briefly surveys and compares two recent beautiful Verifiable Delay Functions...
We construct a verifable delay function (or unique publicly verifiable proof of sequential work) by showing how the Rivest-Shamir-Wagner time-lock puzzle can be made publicly verifiable.
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...
