Powerballs. Worldwide Lottery

Whitepaper

This white paper discusses the concept of a decentralized lottery that utilizes blockchain technology to gather funds, randomly select a winner, allow worldwide participation, and distribute the jackpot with less human involvement. The use of blockchain ensures transparency and fairness, and the anonymity of winners increases the jackpot amount and participation. NFT holders have a lifetime right to vote on the project direction and receive 15% of the repeated jackpot and community benefits.

Introduction

Cryptocurrency and related technologies have faced a significant loss of trust over the past few years, primarily due to human error and poor management. This has resulted in a decrease in user participation and a lack of new ideas and technologies in the space.

The traditional lottery system, while offering massive jackpots, has limited accessibility and is often unengaging for participants. To address these issues, we propose a decentralized lottery that utilizes blockchain technology to increase transparency, fairness, and accessibility to a worldwide audience. This whitepaper presents the Powerballs blockchain lottery, built on Ethereum technology, which offers a new and exciting way for people to participate in lotteries while owning unique digital assets. Our goal is to improve conventional lottery systems and eliminate human-related behavior and wrongdoing.

Why Create a Decentralized Lottery?

A decentralized lottery built on blockchain technology offers unlimited freedom and privacy. However, the development time and effort required to create a fully self-controlled lottery can be significant. Therefore, the Powerballs blockchain lottery project will be updated gradually to become more independent from human error. The Powerballs blockchain lottery seeks to improve conventional lottery systems by creating a transparent and fair lottery process that eliminates the need for intermediaries and human involvement. Our goal is to create a lottery system that is resistant to any kind of tampering and provides complete traceability of the entire process.

Drawing Method

In the initial stages of the project, the drawing method will be highly entertaining and involve community interaction. As the project progresses, less human involvement will be required for the drawing process. The community will vote on the method and timing of the drawing. For example, the PB community may vote to print all NFT ticket numbers from 1 to the last number minted for a particular period. The picking method could involve shooting at a printed banner from a mile away with a rifle, and the winning number would be the one that is hit.

Distribution

The funds will be distributed as follows: 70% of the total mint amount will go to the main jackpot, 15% will go to the repeated jackpot among all PB NFTs, and the remaining 15% will cover operational expenses and the founders' fee. The community will vote on the mint/sale period, draw date, and method.

Conclusion

The proposed decentralized lottery utilizing blockchain technology offers a new and exciting way for people to participate in lotteries and own unique digital assets. It addresses the issues of transparency, fairness, and accessibility that traditional lotteries face, and offers a more engaging and interactive experience for participants.

Powerballs blockchain lottery concept using Ethereum technology would work as follows:

Collection of Funds: Participants would send their desired amount of cryptocurrency, such as ETH, to a smart contract address, which acts as the lottery ticket. Or mint an NFT for infinite participation and have rights to vote on the project.
Generation of Winners: A random number generator function would be coded into the smart contract, which would determine the winner(s) of the lottery once all the tickets have been sold.
Automatic Fund Distribution: Upon the completion of the drawing, the smart contract would automatically transfer the winning amount to the addresses of the winning ticket holders.
Transparency and Traceability: All transactions and the results of the lottery would be recorded on the Ethereum blockchain, providing complete transparency and traceability of the lottery process.
Anonymity: Participants can remain anonymous if they choose to, as the Ethereum blockchain only stores the public address of the ticket holders.

In summary, a blockchain lottery built on Ethereum technology would offer a decentralized, transparent, and automatic way to participate in a lottery, without the need for intermediaries or human involvement.

Random Winner Generator

Smart contract code for a random winner generator on the Ethereum blockchain using Solidity


pragma solidity ^0.8.0;

contract RandomWinnerGenerator {
    
    // The array to store all the participants
    address[] public participants;
    
    // Event to notify the winner
    event Winner(address winner);
    
    // Function to add participants
    function participate() public payable {
        participants.push(msg.sender);
    }
    
    // Function to select a random winner
    function selectWinner() public {
        // Check if there are enough participants
        require(participants.length > 0, "No participants found.");
        
        // Generate a random index based on the number of participants
        uint randomIndex = uint(keccak256(abi.encodePacked(block.timestamp, block.difficulty))) % participants.length;
        
        // Declare the winner
        address winner = participants[randomIndex];
        
        // Trigger the Winner event
        emit Winner(winner);
    }
}

Automatic Fund Distributor

Smart contract code on Solidity that automatically sends the funds to the winner's wallet


pragma solidity ^0.8.0;

contract RandomWinnerGenerator {
    
    // The array to store all the participants
    address[] public participants;
    
    // Event to notify the winner
    event Winner(address winner);
    
    // Function to add participants
    function participate() public payable {
        participants.push(msg.sender);
    }
    
    // Function to select a random winner and distribute the funds
    function selectWinner() public {
        // Check if there are enough participants
        require(participants.length > 0, "No participants found.");
        
        // Generate a random index based on the number of participants
        uint randomIndex = uint(keccak256(abi.encodePacked(block.timestamp, block.difficulty))) % participants.length;
        
        // Declare the winner
        address winner = participants[randomIndex];
        
        // Transfer the funds to the winner's wallet
        winner.transfer(address(this).balance);
        
        // Trigger the Winner event
        emit Winner(winner);
    }
}

Automatic Fund Distributor
3 Winners

Smart contract code on Solidity that selects 3 winners and automatically sends the winning amounts to their wallet addresses:

70% jackpot
20% jackpot
10% jackpot


pragma solidity ^0.8.0;

contract RandomWinnerGenerator {
    
    // The array to store all the participants
    address[] public participants;
    
    // The percentage of the jackpot for each winner
    uint public firstWinnerPercentage = 70;
    uint public secondWinnerPercentage = 20;
    uint public thirdWinnerPercentage = 10;
    
    // Event to notify the winners
    event Winner(address winner, uint amount);
    
    // Function to add participants
    function participate() public payable {
        participants.push(msg.sender);
    }
    
    // Function to select the winners and distribute the funds
    function selectWinners() public {
        // Check if there are enough participants
        require(participants.length >= 3, "At least 3 participants are required.");
        
        // Generate random indices based on the number of participants
        uint firstWinnerIndex = uint(keccak256(abi.encodePacked(block.timestamp, block.difficulty))) % participants.length;
        uint secondWinnerIndex = (firstWinnerIndex + 1) % participants.length;
        uint thirdWinnerIndex = (firstWinnerIndex + 2) % participants.length;
        
        // Declare the winners
        address firstWinner = participants[firstWinnerIndex];
        address secondWinner = participants[secondWinnerIndex];
        address thirdWinner = participants[thirdWinnerIndex];
        
        // Calculate the amount for each winner
        uint totalJackpot = address(this).balance;
        uint firstWinnerAmount = (firstWinnerPercentage * totalJackpot) / 100;
        uint secondWinnerAmount = (secondWinnerPercentage * totalJackpot) / 100;
        uint thirdWinnerAmount = (thirdWinnerPercentage * totalJackpot) / 100;
        
        // Transfer the funds to the winners' wallets
        firstWinner.transfer(firstWinnerAmount);
        secondWinner.transfer(secondWinnerAmount);
        thirdWinner.transfer(thirdWinnerAmount);
        
        // Trigger the Winner events
        emit Winner(firstWinner, firstWinnerAmount);
        emit Winner(secondWinner, secondWinnerAmount);
        emit Winner(thirdWinner, thirdWinnerAmount);
    }
}
