Introduction

HackerLink Grant is a quadratic funding dapp that supports early-stage projects and ideas from open source developer communities. Grant allows both community members and organizations (foundations, venture funds, senior projects) to participate in funding early developer projects and blockchain ventures.

Starting July 15, 2021, the Harmony Grant Online Hackathon is officially launched at Hackerlink.io, DoraHacks’ open source developer incentive platform. The hackathon is sponsored by Harmony with a $50,000 prize pool to encourage developers to contribute ideas and early-stage projects to the Harmony ecosystem. The whole prize pool will be allocated based on the results of the community voting. Developers from around the world are welcomed to submit blockchain projects based on (or planning to build on)Harmony!

In addition to the generous prizes, the Harmony technical team has designed a series of workshops and panels to explain how to get started with Harmony development. Applying for the hackathon will also bring you the chance to present your project via DoraHacks Live Demo Sessions. Shout out to the world your vision and codes! *Notice: We can offer gas fee support during the hackathon! Please contact @hackerlinkofficial on Telegram for more details.

Voting Mechanism

https://vitalik.ca/general/2019/12/07/quadratic.html Please refer to Vitalik Buterin's article “Quadratic Payments：A Primer" if you are not familiar with Quadratic Voting and Quadratic Funding mechanisms.

An explanation article in Chinese is written by Eric Zhang (https://www.matataki.io/p/6113).

HackerLink provides quadratic funding tools to the DoraHacks global hackathon community.

There are two funding sources -- the community donation and the sponsor's prize pool.

For individual community contributors: you can donate to any project(s) you like with your wallet. By clicking "Vote" following that project, you will be able to enter votes and the smart contract will return the cost (or the amount of donation) for the votes. Your votes will eventually determine how the sponsor pool gets distributed.

Before voting, make sure your wallet is connected to Harmony Mainnet and you have ONE tokens ready. The first vote will cost 10 ONE.

This QF round is using the Quadratic Funding V2 Protocol. Details of the new protocol can be found here: https://dorafactory.medium.com/quadratic-funding-v2-protocol-anti-sybil-fairness-and-scalability-on-chain-2a7aec43541c

There is a major new component in the Quadratic Funding V2 Protocol -- the quadratic progressive tax system. The QF V2 protocol uses the quadratic progressive tax system to mitigate inequality of the original quadratic funding protocol.
