Sparkle Proof Of Loyalty

Sparkle Proof Of Loyalty is a public GitHub repository containing Ethereum smart contracts for a loyalty rewards program. Its README describes rewards for holding Sparkle tokens over a maturity period and says the contracts should be compatible with ERC-20 tokens. Truffle is identified as the development and testing environment.

Practical overview

When it fits

Use the repository when researching or developing a token-based loyalty contract design, particularly if you want to inspect its documented reward periods and Truffle workflow.

Who it is for

  • Developers exploring Ethereum smart contracts for token-based loyalty rewards.
  • Developers interested in a Truffle and Ganache-CLI local development setup.

Documented uses

  • Examine a holding-period-based loyalty rewards design.
  • Explore an Ethereum contract project described as ERC-20 compatible.
  • Set up the documented Truffle and Ganache-CLI tools for local development.
Before you choose

Requirements & limits

The project is available as a public GitHub repository. The README says Mainnet and Ropsten contract links are currently unavailable.

  • The README describes ERC-20 compatibility but the project is presented as a set of specialized contracts for its loyalty program.
  • The documented development stack specifies older pinned versions, including Node.js 10.11.0 and Truffle 5.1.23.
  • The README says Mainnet and Ropsten contract links are unavailable, which limits its usefulness for finding a published deployment.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up the documented Truffle tools

Install the Truffle and Ganache-CLI tools listed for local contract development.

Before you start

  • Node.js 10.11.0
  • Docker 19.03.8
  • Truffle 5.1.23
  • Ganache-CLI 6.9.1

Steps

  1. Install Node.js and Docker using their respective installation guidance.

  2. Install Truffle with the command below.

    Documented command
    npm install -g truffle@5.1.23

  3. Install Ganache-CLI with the command below.

    Documented command
    npm install -g ganache-cli

Expected outcome

The Truffle and Ganache-CLI tools are installed for the repository's described local development setup.

Guide limitations

  • The README does not provide the Node.js or Docker installation procedures.
  • This setup recipe does not cover running tests, deploying contracts or connecting to a live network.
