The problem ChainWhiZ solves

1. Dapp building is still not mainstream in the industry due to the lack of dedicated and comprehensive marketplaces which connect developers with clients. We are building an open-source freelancing marketplace that we hope would one day be the pioneer for Dapp building.

2. High platform fees on pre-existing freelancing marketplaces decrease the earning potentials of developers hugely. Our platform boasts a zero platform fees architecture due to the power of decentralization.

3. In the present scenario, it is not possible for a general blockchain enthusiast with an idea to build a Dapp. Having a strong technical prowess in coding and development is crucial in order to even choose an ideal freelancer. Our platform with its community voting protocols makes it possible for any enthusiast with an idea to build a Dapp without writing or knowing how to write a single line of code.

Challenges we ran into

1. Implementing functions for stake based voting
2. Implementation of async and await
3. Figuring out the cron tasks.
