Starter template for an account based voting mechanism

Introduction

This starter template has been build for the Advanced Phala Challenge of the amsterDOT hackathon. The template can be a start for developers who want to try the Phala privacy-preserving fat contract feature, in combination with wallet accounts from PolkadotJs.

The template can for example be expanded to build more advanced features like:

• Governance proposals
• Delegating voting rights to other accounts
• RBAC mechanisms

In the current Phala js-sdk examples, I missed an easy example that would allow me to do something with multiple PolkadotJs accounts. This seemed like a fun challenge to figure out myself. So I decided to build a simple account based voting mechanism, that is still making use of the Phala fat contract benefits! 😄
