1. Gabatarwa

Tattara jama'a don kuɗi (Crowdfunding) ya canza tsarin ba da kuɗin 'yan kasuwa ta hanyar haɗa masu ƙira kai tsaye da masu saka hannun jari ta dandamali kamar Kickstarter da Indiegogo. Duk da haka, tattara kuɗi na al'ada yana fuskantar manyan kalubale da suka haɗa da manyan kuɗin ma'amala (3-5%), rashi na bayyana gaskiya, nauyin bin ka'idoji, da iyakokin haɓakawa. Waɗannan matsalolin suna rage tasirin tattara kuɗi a matsayin kayan aiki don ƙirƙira da haɓaka.

Fasahar Blockchain tana ba da madadin tsarin da ba shi da cibiyoyi (decentralized), mai bayyanawa, da tsaro wanda ke magance waɗannan rashin inganci. Ta hanyar kawar da masu shiga tsakani, blockchain yana rage farashin ma'amala yayin samar da hanyoyin tantancewa maras canzawa. Haɗin stablecoins kamar USDT da USDC yana rage saurin canjin kuɗin kripto (cryptocurrency), wanda ya sa tattara kuɗi na tushen blockchain ya zama mafi dacewa don karɓuwa ta al'ada.

2. Tsarin da Ake Shawarawa

Tsarin da ake shawarawa ya haɗa fasahar blockchain, stablecoins, sanya alama (tokenization), da kwangilolin wayo (smart contracts) don ƙirƙirar cikakkiyar tsarin tattara kuɗi wanda ke magance iyakokin dandamali na al'ada.

2.1 Haɗin Stablecoin

Stablecoins irin su USDT da USDC suna samar da kwanciyar hankali na farashi ta hanyar haɗa su da kuɗin ƙasa (fiat), suna magance damuwa game da saurin canji mai alaƙa da kudaden kripto kamar Bitcoin da Ethereum. Wannan kwanciyar hankali yana ba da damar ma'amaloli masu iya hasashe da kuma sauƙin juyawa zuwa kuɗin gida, musamman mahimmancinsa a kasuwannin masu tasowa kamar Turkiyya inda kwanciyar hankali na kuɗi ke da damuwa.

2.2 Tsarin Sanya Alama (Tokenization)

Sanya alama (Tokenization) yana ba da damar mallakar kadarori a ɓangare (fractional ownership) ta hanyar ƙirƙirar alamomin dijital (digital tokens) da ke wakiltar haƙƙin mallaka ko rabon kudaden shiga. Wannan tsari yana haɓaka kuɗin ruwa (liquidity) ta hanyar ba da damar ciniki a kasuwa ta biyu na waɗannan alamomin. Tsarin sanya alama yana bin ma'auni na ERC-20 don alamomin da za a iya musanya (fungible tokens) da ERC-721 don alamomin da ba za a iya musanyawa ba (non-fungible tokens) waɗanda ke wakiltar kadarori na musamman.

2.3 Aiwar da Kwangilar Wayo (Smart Contract)

Kwangilolin wayo (Smart contracts) suna sarrafa muhimman hanyoyin aiki ta atomatik waɗanda suka haɗa da bin ka'idojin KYC/AML, rarraba kuɗi, tabbatar da matakai, da hanyoyin maido da kuɗi. Waɗannan kwangilolin da ke aiwatar da kansu suna aiki akan sharuɗɗan da aka ƙayyade, suna tabbatar da bayyana gaskiya da rage farashin aiki.

Ƙirar kimanta alama (token valuation model) ta haɗa da abubuwa da yawa ciki har da tushen aikin, buƙatun kasuwa, da sigogin kuɗin ruwa. Babban dabarar kimantawa ita ce:

$V_t = \frac{TVL \times (1 - \rho)}{T_s} \times e^{-\lambda t} \times \sigma_m$

Inda:

• $V_t$ = Ƙimar alama a lokacin t
• $TVL$ = Jimillar Ƙimar da aka Kulle a dandamali
• $\rho$ = Kashi na kuɗin dandamali
• $T_s$ = Jimillar wadatar alama
• $\lambda$ = Ma'aunin rangwame na kuɗin ruwa
• $\sigma_m$ = Ma'auni mai nuna yanayin kasuwa

Aiwatar da kwangilar wayo (smart contract) tana bin ƙa'idodin tabbatarwa na yau da kullun don tabbatar da tsaro da aminci. Aikin sauyin yanayin kwangila an ayyana shi kamar haka:

$S_{t+1} = f(S_t, I_t, \Theta)$

Inda $S_t$ ke wakiltar yanayin yanzu, $I_t$ yana wakiltar ma'amalolin shigarwa, kuma $\Theta$ yana wakiltar sigogin kwangila.

3.2 Aiwatar da Lambar (Code)

Mai zuwa lambar kwangilar wayo da aka sauƙaƙa tana nuna ainihin aikin tattara kuɗi:

pragma solidity ^0.8.0;

    uint256 public deadline;
    uint256 public totalRaised;
    mapping(address => uint256) public contributions;
    
    event FundTransfer(address backer, uint256 amount, bool isContribution);
    
    constructor(uint256 _fundingGoal, uint256 _duration) {
        creator = msg.sender;
        fundingGoal = _fundingGoal;
        deadline = block.timestamp + _duration;
    }
    
    function contribute() external payable {
        require(block.timestamp < deadline, "Yakin tattara kuɗi ya ƙare");
        contributions[msg.sender] += msg.value;
        totalRaised += msg.value;
        emit FundTransfer(msg.sender, msg.value, true);
    }
    
    function withdrawFunds() external {
        require(msg.sender == creator, "Mai ƙira kawai zai iya cire kuɗi");
        require(totalRaised >= fundingGoal, "Manufar tattara kuɗi bai kai ba");
        require(block.timestamp >= deadline, "Yakin tattara kuɗi bai ƙare ba");
        
        payable(creator).transfer(totalRaised);
        emit FundTransfer(creator, totalRaised, false);
    }
    
    function getRefund() external {
        require(block.timestamp >= deadline, "Yakin tattara kuɗi bai ƙare ba");
        require(totalRaised < fundingGoal, "Manufar tattara kuɗi ta kai");
        require(contributions[msg.sender] > 0, "Babu gudunmawa");
        
        uint256 amount = contributions[msg.sender];
        contributions[msg.sender] = 0;
        payable(msg.sender).transfer(amount);
        emit FundTransfer(msg.sender, amount, false);
    }
}
