This project will create a fair playground to eliminate social injustice. Greatsun aims to develop with the goal of social benefits. All proceeds from the project will be used to build social benefits. 

Greatsun is a system created on the Blockchain technology platform. 

The first project announced by Greatsun to the world is the Blockchain Odd-Even Lottery project. This algorithm and technology help players increase their winning odds by tens or hundreds of times compared to traditional lotteries. 

The lottery drawing algorithm is based on the Hash code of the Blockchain, ensuring natural and unaltered results.

For example: You spend $2 to buy 1 ticket, with the tickets divided into 50% even and 50% odd. If you win, you will receive $3.9, equivalent to a distribution of 97.5%.

This technology is openly sourced, and the digital data is stored on the Blockchain, ensuring complete transparency and security.

Participants can log in with the Metamask e-wallet and buy tickets. They can also create an account and purchase cryptocurrency to buy tickets. 

Anyone can participate, and no government in the world can interfere because Blockchain technology is evolving based on future trends. Therefore, the number of tickets sold is beyond imagination, and the system is highly secure due to the use of Blockchain technology. The rewards will be substantial and equitable, without any geographical or human barriers.

Greatsun's desire is to utilize the profits from the system to construct schools, sports centers, bridges, while also supporting and developing projects that bring benefits to the community, including scholarships, research, and the development of science and technology.

With the Greatsun Blockchain Odd-Even Lottery, unnecessary costs are eliminated, resulting in extremely high prize distributions. There are no printing fees, and it is publicly transparent. People from all over the world participate, and player data and prizes are publicly disclosed on the system. 

Blockchain technology is being effectively applied worldwide, and we cannot deny that.

On our system, participants can purchase tickets anonymously. However, we have a mechanism that allows players to choose where they contribute to the social development fund before they win the prize.

Example: when you earn $10, the smart contract will send the money directly to your e-wallet and automatically process the payment for your fund contribution.

So when you choose a place to contribute to the fund, the contribution ratio will be allocated to the wallets of the National Fund, the provincial fund, and the district fund that you have chosen. The total amount contributed by everyone to each fund will be announced on our uncheatable Blockchain system.

The Greatsun system will have ambassadors responsible for distributing funds and working to build and develop the local area where you contributed to the fund. These ambassadors can be elected from among the citizens, locals, or nominated by the system. All project expenses will be publicly disclosed on the Blockchain to avoid fraud and ensure the proper use of funds for community support.

Blockchain is a system that surpasses the management barriers of governments at all levels. However, we always hope that all the benefits of the project will be delivered to each country in the most perfect way possible. 

Similarly, the reason why these prizes are so large is because of the intelligent algorithms and technology, and the absence of taxes and fees, eliminating many expenses that would deplete the players' funds. And the profits do not go into the benefits of a group.

Greatsun will distribute in a perfect way. It will truly be a wonderful tool to help build our ideal world.
