4. Aiwatarwa da Nazarin Fasaha

4.1 Tushen Lissafi

Tsaron kuɗin dijital ya dogara ne akan mahimman abubuwan sirri. Don kuɗin quantum, ka'idar rashin kwafi tana ba da tsaro na asali:

$|\psi\rangle \rightarrow |\psi\rangle \otimes |\psi\rangle$ ba zai yiwu ba ga jihohin quantum da ba a sani ba

Rashin iya jabun kuɗin quantum ana iya bayyana shi kamar haka:

$Pr[Verify(\$_{quantum}) = 1 | \$_{quantum} \notin Valid] \leq \epsilon(\lambda)$

inda $\epsilon(\lambda)$ ba kadan bane a cikin sigar tsaro $\lambda$.

4.2 Sakamakon Gwaji

Takardar ta gabatar da nazarin kwatancen nau'ikan kuɗi daban-daban a cikin kaddarori masu yawa. Manyan binciken sun haɗa da:

A ƙasa akwai sauƙaƙan aiwatar da kwangilar wayo don CBDC mai shirye-shirye:

// Misalin Solidity don kuɗi mai shirye-shirye
pragma solidity ^0.8.0;

contract ProgrammableCBDC {
    mapping(address => uint256) private balances;
    address public centralBank;
    
    constructor() {
        centralBank = msg.sender;
    }
    
    function transferWithCondition(
        address to, 
        uint256 amount, 
        uint256 timestamp
    ) external {
        require(balances[msg.sender] >= amount, "Balance bai isa ba");
        require(block.timestamp >= timestamp, "Sharadin canja wuri bai cika ba");
        
        balances[msg.sender] -= amount;
        balances[to] += amount;
        
        emit ConditionalTransfer(msg.sender, to, amount, timestamp);
    }
    
    function automatedMonetaryPolicy(uint256 inflationRate) external {
        require(msg.sender == centralBank, "Bankin tsakiya kawai zai iya aiwatarwa");
        
        // Daidaita ma'auni bisa la'akari da ƙimar hauhawar farashin kaya
        for(uint256 i = 0; i < accountCount; i++) {
            address account = accounts[i];
            balances[account] = balances[account] * (100 + inflationRate) / 100;
        }
    }
