2022 Winners

Grand Prize

$15,000

NAT

Description We’ve built a reward-based translation system. The main system is set up through a browser extension and it includes 5 steps. First, when you click the extension on the original English web page. It calls DeepL APIs to generate the translated draft and stores it into FireStore, a cloud document database organizing data in a key-value way. We still need translators to proofread the draft, though DeepL has done a good job. Translators review the results in FireStore and modify mistakes.

After that, our extension transfers corrected drafts into permanent stores, Arweave, utilizing Koii Network. Koii network is a middle layer between the application layer and the storage layer. Introducing concepts of attention, Koii Network helps users store materials in AR and get attention rewards when people browse their contents with its smart contract. Our system works along the same line. Through Koii Network, a draft is divided into a few pieces and they are minted into NFTs, which belong to translators.

Finally, click the extension, it reads translation NFTs from Koii Network and displays them on users’ screens. In this progress, owners of translation NFTs, translators, are supposed to get rewards due to the attention mechanism of Koii Network. The higher quality your translation is, the more rewards you will obtain. Through such positive feedback, translators get paid, and users have a better understanding of projects’ contents.

bytehash

+ Polygon Best dApp Built on Polygon Bounty Winner

Description We have developed a blockchain agnostic user interface where any one from developer to normal user can interact with any smart contract on any blockchain. This tool basically helps developers but can be used by normal people as well. Our tool helps solve below issues: 1. If you are a smart contract developer and use hardhat or other environments, you often tend to copy the code to remix and try to compile there and then interact with contracts from there. Even after you have compiled and generated an abi in your development environment already. 2. Already deployed contracts interaction, Even if the contracts are verified, published and the ABI is publicly available you cannot interact them in your remix(Either you have to copy complete code also take care of imported contracts etc.,).

Fluidity

$1000

Decentology Smart Contract Developers Bounty Winner

Description Fluidity is a bootstrapping utility for DAOs / Organizations to sell an NFT for ETH while “streaming” their token to the NFT owner/buyer over a set vesting period. With Fluidity, DAOs can set up their NFT contract and their members can mint and purchase these NFTs for ETH which kicks off a stream of DAO tokens over a month. This reduces the sell pressure on their token and diversifies their treasure with stable and usable tokens. Fluidity is built on Decentology Hyperverse. With Hyperverse, we’ve built a custom Smart Module which integrates Superfluid contracts. We’ve also built a template front-end leveraging the Hyperverse libraries, which allows DAOs to setup their NFT contracts and for their users to mint their NFTs which will kick off the stream of tokens.

This project utilizes a decentralized persistent database called GunDB database to store user emails and is hosted on Fleek. We are using a GunDB to maintain decentralization and give every user their own database. Users will be assigned a unique string URL which is stored on our smart contract. Additionally, prior to sending an email, the user has to sign the message to verify the email is being sent by the person they claim to be.

Dev Sharks

$750

Filecoin & IPFS 3rd Place Bounty Winner

Description We invented a simple, composable standard for time-limited rights: leases, to complement the deeds defined in ERC-721. We invented a simple structure that makes it easy to express a lease in terms of asset and timeframe, and to transfer leases - even to break them apart into smaller units. We created an ERC-targeted Ethereum Improvement Proposal for the use and review by the community. Getting this right and prepared was a real bit of work! https://github.com/rhdeck/time-limited-token/blob/main/eip-time-limited-tokens.md And we built an example implementation of the lease, deployed as a simple app for leasing and transferring parts of leases. In the spirit of subletting, we called it Web3-n-B: https://shy-fire-7283.on.fleek.co/
