The problem SiddhiNet solves

SiddhiNet is a Secure Streaming Network for Skilled Professionals of Soverign Individuals and Self Organised Occults. Skills are defined as Self Soverign Commodities of Non Fungible Token Kind. Privacy Preserving Proofs are constructed using Zokrates Toolkit for Skill Self Verification, Sequence Verification and Social Verification. The Solidity Smart Contracts are generated from these Privcy Preserving Proofs. Following are the Primary features

Skill Self Verification through Privcy Preserving Zokrates Contracts
Skill Summary Verification through Privacy Preserving Zokrates Contracts
Skill Sequence Verification through Privacy Preserving Zokrates Contracts
Skill Social Verification through Minimal Anti Collusion Framework
Skill Selection Game using Chainlink VRF Randomness 
Skill Session Token as Chainlink VRF Generated One Time Pad
Skill Streaming with Time Locked Pause and Freeze Facilities
Skill Token Distribution over Money Streaming Protocol
Skill Token Supply Expansion and Contraction on Bonding Curves
Skill Streaming based on Multi Dimensional Time Locks
Skill Token Integration with Anonymous Zether Framework
Multi Dimensional Time Locks using Verifiable Delay Functions
Privacy Preserving Confidential Skill Share and Yield Tokens

Challenges we ran into

Challenges with applying Time Locks to Time Weighted Average Algorithms
Challenges with applying Verifiable Delay Functions to Money Streaming
Challenges into Integration on Non Fungible Token Specifications
