Please describe your proposed solution.

Kwarxs bridges blockchain and real-life projects by providing a crowdfunding vehicle that enables fractional ownership of solar energy plants profits (the same technology could be extended to other projects), to later distribute part of the annual profits among investors. Both the investment and the profit sharing is done through transactions on the Cardano blockchain using ADA as a currency, and the proof of investment used to claim the investor's share of the profit is done via Cardano native Non-Fungible Tokens (NFTs).

The primary objective of this project is to amass an extensive portfolio of green and renewable energy resources. This portfolio will include solar power plants, bio-diesel refineries, and tree farms renowned for their high CO2 absorption capabilities, among others. Our aim is to offer practical and robust solutions to offset carbon emissions, thereby significantly reducing our collective carbon footprint.

Kwarxs has committed to establishing itself as the most significant utility project on the Cardano platform. Our strategy is designed to yield a sustainable, long-term passive income for all members of the Kwarxs community. We aim to achieve this through the continual development and refinement of our proprietary system and smart contracts.

Our goal is to enhance their usability for a growing user base, thereby driving the project's impact and reach. In the future, we envision the Kwarxs-DAO project to become entirely autonomous. It will be self-organizing via the DAO and contribute to ongoing decentralization efforts.

This vision underscores our commitment to forging new paths in green energy solutions, utilizing the power of blockchain technology, and supporting our community through reliable passive income opportunities. We believe these efforts will position Kwarxs at the forefront of sustainable innovation, driving forward both environmental responsibility and financial independence for our users.

The built protocol allows to do the following actions:

1 - Investment and NFT minting

In order to buy an NFT, a user first has to clear KYC with Blockpass. Once this is done, by clicking the "Buy" button in the website the following sequence is triggered:

• Using the connected address, a KYC status request is sent to Blockpass.
• If a successful response is received from Blockpass, a transaction minting the NFT and sending it to the connected address, and paying to the operator's wallet the price in ADA displayed on the website is built and sent to the user for signature. The signed transaction is then submitted to the blockchain and the NFT is minted.

2 - Profit sharing

After converting the profit generated by the solar plant to ADA (or any other Cardano native token), the administrator deposits it into the profit sharing validator, an escrow script that locks them under the profit distribution rules.

A separate deposit is required for each collection of NFTs supported (at launch, there would be four collections supported for different sizes of investment), and the information about how much value (e.g how many Lovelaces) can be withdrawn by each NFT holder is attached as part of the deposit transaction.

3 - Profit distribution

Owners of the NFTs can use them to claim their share of the profit previously deposited by the administrator and locked in the profit sharing validator. There is no need to stake the NFTs to do so. To prevent fraud, every time profit is claimed, the NFT is atomically burnt and re-minted, updating a counter included as part of the token name.

Kwarxs NFTs are grouped in 4 categories representing different rarities and APY%. All NFTs come with a nice piece of art, 100% handmade and unique.

The first collection, "Sun Gowds", is based on the sun god Helios in relation to our solar farms. This is a sample of the art attached to the NFTs:

Please define the positive impact your project will have on the wider Cardano community.

Kwarxs is committed to pioneering the concept of fractionalized ownership and governance within the sustainable energy sector. This revolutionary approach will empower investors to share the profits generated by solar power plants, thereby promoting active participation in the green revolution. It also fosters an environment for the investment community to directly contribute towards the establishment of new solar power facilities.

Our strategic objectives align with the broader aim to augment the proportion of energy derived from renewable sources. This initiative is not only central to Kwarxs' operational framework but is also crucial to the attainment of international climate goals. Such objectives are highlighted in the 2030 agenda and are aimed at a significant reduction in the world's carbon footprint.

With the long-term vision of reaching zero-emissions by the year 2050, Kwarxs is committed to playing an integral role in catalyzing the transition to cleaner, sustainable energy solutions. Through our innovative approach, we aim to make a tangible impact in the fight against climate change, while providing our investors with profitable, socially responsible investment opportunities.

The primary measure of this project's success is gauged by the installed capacity of solar energy, expressed in Megawatts, made possible by investments channeled through the Cardano blockchain.

A secondary, yet equally significant, success indicator is the quantity of individual investors, particularly from the smaller investor demographic, who partake in this investment opportunity. The emphasis here is on the ability of these investors to acquire fractional ownership of the solar farms, thereby democratizing access to renewable energy investments. These metrics, combined, serve to reflect our commitment to promoting sustainable energy and broad-based investor participation.

We are optimistic about deploying Kwarxs on the Cardano mainnet within four months of securing the necessary funding. Significant progress has already been made towards this goal, with a prototype live on testnet and a targeted mainnet launch currently slated for Q2 2024.

Upon the successful launch of the project, our platform will be primed for investors to mint their NFTs. These NFTs will symbolize their entitlement to a fraction of the profits yielded by the power plants.

It's noteworthy that our operations are already underway with solar farms in Germany. Therefore, we can assure investors of profits, even in the first year of operation, calculated from the conclusion of the initial investment round. This assurance underlines our commitment to providing a secure and fruitful investment platform to our investors right from inception.

These resources will enable us to transition the project seamlessly from the testnet phase to mainnet, as well as adding some further functionality. This signifies a key milestone in our journey, bringing us a step closer to realising our vision for a greener, more sustainable future.

What are the key milestones you need to achieve in order to complete your project successfully?

Milestone: Update on-chain dependencies and increase test coverage.

Description: As development of the project started in April 2022, the current on-chain scripts use an old version of Plutarch and work with Plutus V1. In this first milestone, we plan to upgrade dependencies to support Plutus V2 (which among other things will allow us to use reference scripts and make transactions cheaper) and therefore work with a more recent version of Plutarch, making auditing and maintenance of the scripts easier. Test coverage will also be increased, expanding the test suite to include features that were left out such as bulk claiming of rewards.

Outputs:

• Updated Plutarch scripts that use Plutus V2.
• Extended test suite.

Acceptance criteria:

• All tests in the expanded test suite pass when using the updated version of the on-chain scripts.

>Milestone: Refactor the transaction builder and update it to support the Conway era.

Description: The current implementation of the code to build transactions has three components: the backend transaction builder, a minting signature bot and the frontend adapter for partial transactions. These components make use of the deprecated library Bot Plutus Interface. The main purpose of this milestone is to update the code so Conway era transactions are supported. Since this will require a fairly big amount of work (updating dependencies alone would be a challenging task), we will take the opportunity to simplify the design by unifying the code for building transactions and will also move away from unmaintained libraries. Our first option is to use Atlas, as we believe will provide the easiest migration path given the state of our current implementation.

Outputs:

• Refactored code for building transactions that support transactions in the Conway era.

Acceptance criteria:

• Transactions submitted to the Sancho Network, the testnet supporting the Conway era ledger, are successful.

>Milestone: Enhance frontend.

Description: The current implementation of the frontend will be enhanced with new functionality such as support for bulk claiming of rewards and increased display of information related to the user NFTs and Kwarxs operations.

Outputs:

• Enhanced functional frontend from where transactions can be submitted using a variety of light wallets.
• Support for bulk claiming of rewards.
• Visualisation of claimable rewards by users.
• Information about Kwarxs operations in real life, which provide the basis for the utility associated with the NFTs.

Acceptance criteria:

• A transaction interacting with the Kwarxs on-chain scripts via the frontend can be submitted to the Sancho Network using at least 3 different light wallets.
• A transaction claiming rewards in bulk (i.e. rewards from more than 1 NFT owned by the same address) can be submitted to the Sancho Network.
• Users that have their wallet connected can see the aggregated amount of claimable rewards by all their Kwarxs NFTs.
• The Kwarxs website displays information about the solar farms in operation.

>Milestone: Audit the on-chain scripts.

Description: In this milestone, the implementation of the smart contracts will be audited by an external, independent auditor.

Outputs:

• Audit report for the Kwarxs on-chain scripts.

Acceptance criteria:

• An audit report generated by an external auditor is published and shared publicly.

>Milestone: Deploy to mainnet.

Description: The final milestone consists of the final preparations to our database and server towards launching Kwarxs on the Cardano mainnet. Upon successful completion of this milestone, Kwarxs will be live on mainnet.

Outputs:

• The database is populated with all the necessary information and metadata related to the initial mintable collections, consisting of more than 10,000 NFTs.
• A server with the necessary infrastructure to interact with the Cardano mainnet is set up.

Acceptance criteria:

• Transactions interacting with the Kwarxs on-chain scripts can be submitted to the Cardano mainnet via the front end in https://kwarxs.io/.
