2.1 Blockchain 2.0 Fundamentals

Ethereum ya ƙara Blockchain 1.0 na Bitcoin ta hanyar gabatar da kwangilori masu cikakkiyar Turing waɗanda ke ba da damar rikitattun aikace-aikacen da ba su da tushe. Babban ƙididdiga ya ta'allaka ne a cikin Injin Virtual na Ethereum (EVM), wanda ke aiwatar da lambar kwangila a duk nodes na cibiyar sadarwa.

3 Cryptocurrency Implementation

3.1 Token Standards

ERC-20 da ERC-21 ka'idoji suna baiwa fungible da kuma non-fungible token ƙirƙira. Tattalin arzikin token an gina shi a kan samfuran kwangilar wayo waɗanda ke ayyana dokokin canja wuri, mallaka, da haɗin kai.

3.2 Tsarin Tsarin Halittar DeFi

Tsarin gine-ginen ya ƙunshi Layer 0 (ETH foundation), Layer 1 (stablecoins kamar DAI), Layer 2 (lending protocols), da kuma Layer na aikace-aikace (DEXs, prediction markets).

4.1 Common Vulnerabilities

Reentrancy attacks, integer overflows, and access control issues represent critical security threats. The DAO hack of 2016 demonstrated the financial impact of reentrancy vulnerabilities.

4.2 Attack Vectors

Front-running, flash loan attacks, da oracle manipulation sun yi Rekt database statistics sama asarar sama da biliyan $2.

4.3 Hanyoyin Tsaro

Formal verification, kayan aikin bincike ta atomatik kamar Slither da MythX, da shirye-shiryen kyautar bug sun inganta tsaron kwangila. Tsarin Check-Effects-Interact yana hana hare-haren sake shiga.

5 Technical Implementation

5.1 Mathematical Foundations

Elliptic curve cryptography secures Ethereum transactions: $y^2 = x^3 + ax + b$ over finite field $\mathbb{F}_p$. The Keccak-256 hash function: $KECCAK-256(m) = sponge[f, pad, r](m, d)$ where $r=1088$, $c=512$.

5.2 Aiwatar da Code

// Secure ERC-20 Token Implementation
pragma solidity ^0.8.0;

contract SecureToken {
    mapping(address => uint256) private _balances;
    mapping(address => mapping(address => uint256)) private _allowances;
    
    function transfer(address to, uint256 amount) external returns (bool) {
        require(_balances[msg.sender] >= amount, "Insufficient balance");
        _balances[msg.sender] -= amount;
        _balances[to] += amount; // Check-Effects-Interact pattern
        emit Transfer(msg.sender, to, amount);
        return true;
    }
    
    function approve(address spender, uint256 amount) external returns (bool) {
        _allowances[msg.sender][spender] = amount;
        emit Approval(msg.sender, spender, amount);
        return true;
    }
}

Bincike na 1,000 Ethereum kwangilolin kwamfuta ya nuna sake shiga (15%), sarrafa damar shiga (28%), matsalolin lissafi (22%), da sauransu (35%). Tabbatarwar yau da kullun ta rage raunin da 92% a cikin kwangilolin da aka duba.

7 Future Applications

Zero-knowledge proofs da layer-2 scaling solutions za su ba private transactions da kuma mafi girma throughput. Cross-chain interoperability da kuma decentralized identity systems suna wakiltar na gaba evolution na Blockchain 3.0 applications.

8 Critical Analysis

Industry Analyst Perspective

Tsaya Mai Cikakken HangaEthereum's smart contract revolution created a $400B+ DeFi ecosystem but introduced systemic security risks that remain largely unaddressed. The fundamental tension between programmability and security creates an inherent vulnerability surface that bad actors exploit with increasing sophistication.

Silsilar TunaniThe paper correctly identifies that Ethereum's Turing-completeness was both its breakthrough feature and Achilles' heel. Unlike Bitcoin's limited scripting language, Ethereum's EVM enables complex financial instruments but also creates attack vectors that didn't exist in Blockchain 1.0. The security solutions proposed—formal verification, automated auditing—are reactive measures trying to catch up with exponentially growing complexity. As noted in the IEEE Security & Privacy Journal (2023), the "attack surface grows faster than defense capabilities" in smart contract ecosystems.

Highlights and Shortcomings:The paper's strength lies in its comprehensive technical breakdown of Ethereum's architecture and clear explanation of common vulnerabilities. However, it understates the systemic risks of composability—how vulnerabilities in one DeFi protocol can cascade through interconnected contracts, as demonstrated in the $600M Poly Network hack. Compared to academic benchmarks like the CycleGAN paper's rigorous validation methodology, this analysis lacks quantitative security metrics for different contract patterns.

Jagorar Aiki:Dole ne Developers su ba da fifiko ga tsaro fiye da saurin fasali, aiwatar da masu katsewar da'ira da iyakar fallasa mafi girma. Dole ne Masu zuba jari su nemi bincike mai zaman kanta daga kamfanoni da yawa, ba kawai na'urorin bincike ta atomatik ba. Dole ne Masu gudanarwa su kafa tsarin alhakin kwangilar wayo. Dole ne masana'antu su wuce guntuwa mai amsawa zuwa hanyoyin haɓaka tsaro-ta-zane, watakila aro daga hanyoyin bincike yanayin gazawar injiniyan sararin samaniya.

Kamar yadda Bankin don Haɗin gwiwar Ƙasashen Duniya ya lura a cikin rahotonsu na cryptocurrency na 2023, "DeFi yana kwafin kuɗin gargajiya tare da ingantaccen blockchain amma kuma haɗarin gargajiya wanda lahani na fasaha ya haɓaka."
