Publicly verifiable secret sharing

Publicly Verifiable Secret Sharing         
In cryptography, a secret sharing scheme is publicly verifiable (PVSS) if it is a verifiable secret sharing scheme and if any party (not just the participants of the protocol) can verify the validity of the shares distributed by the dealer.
Verifiable random function         
PUBLIC-KEY CRYPTOGRAPHIC PSEUDORANDOM FUNCTION
Verifiable unpredictable function
In cryptography, a verifiable random function (VRF) is a public-key pseudorandom function that provides proofs that its outputs were calculated correctly. The owner of the secret key can compute the function value as well as an associated proof for any input value.

SNIPPET OF SOURCE CODE THAT ALLOWS A BUG OR PROBLEM TO BE DEMONSTRATED AND REPRODUCED
Minimal Working Example; Minimal working example; Minimal workable example; Minimal complete verifiable example; Short self-contained correct example; Min-reprex
In computing, a minimal reproducible example (abbreviated MRE) is a collection of source code and other data files which allow a bug or problem to be demonstrated and reproduced. The important feature of a minimal reproducible example is that it is as small and as simple as possible, such that it is just sufficient to demonstrate the problem, but without any additional complexity or dependencies which will make resolution harder.

Publicly Verifiable Secret Sharing

In cryptography, a secret sharing scheme is publicly verifiable (PVSS) if it is a verifiable secret sharing scheme and if any party (not just the participants of the protocol) can verify the validity of the shares distributed by the dealer.

In verifiable secret sharing (VSS) the object is to resist malicious players, such as
(i) a dealer sending incorrect shares to some or all of the participants, and
(ii) participants submitting incorrect shares during the reconstruction protocol,cf. [CGMA85].
In publicly verifiable secret sharing (PVSS), as introduced by Stadler [Sta96], it is an explicit goal that not just the participants can verify their own shares, but that anybody can verify that the participants received correct shares. Hence, it is explicitly required that (i) can be verified publicly.

The method introduced here according to the paper by Chunming Tang, Dingyi Pei, Zhuo Liu, and Yong He is non-interactive and maintains this property throughout the protocol.
