BlockChain-Unchained

Cryptography & BlockChains from Scratch

Cryptography

A head first dive into the cryptography used in the modern day technologies. I’ve explored RSA & ECC, both of which are already in use widely and have had substantial impact on the current Scuerity Systems. ECC is even more powerful, and has seen applications in blockchain. We explore one of the standards used in Bitcoin; secp256k1.

Solidity

An Exploration into the world of smart contracts. I have a stab at Building Smart Contracts, which are under ./Solidity/Build/. Meanwhile also exploring the Exploits and Vulnerabilities found in Solidity: From Re-Entrancy exploits draining all the ether from a smart contract and Phishing Attacks to get Priviledge Escalation, upto catching other Hackers using HoneyPot Retaliation.

Build

I explore the bit by bit building of Solidity Code, along with Solidity Best Practices.

0. Hello World
1. Getters and Setters
2. Gas
3. Modifier: Pure, View, Other
4. Inderitance

Break

A list of all the Solidity Exploits:

• Overflow Attack
• Underflow Attack
• ReEntrancy Attack
• Self-Desruction Attack
• Denial of Service (DoS) Attack
• Phishing Attack
• Hiding Malicious Code
• Honey Pot Attack/ Honey Pot Retaliation

I have also included the fixes for the attacks: Exploits Fixes and Attacks Fixes

密码学和区块链blockchain从头开始

加密

一个头脑发热的人深入研究现代技术中使用的密码学。我研究过RSA和ECC，这两种技术都已经在广泛使用，并对当前的Scuerity系统产生了重大影响。ECC功能更强大，在区块链blockchain中也有应用。我们探索BTC使用的标准之一：secp256k1。

对智能合约世界的探索。我有一个构建智能合约的尝试，它位于./Solidity/Build/下。同时，还探讨了Solidity中发现的漏洞和漏洞：从重新进入漏洞利用耗尽智能合约的所有乙醚和网络钓鱼攻击获得特权升级，直到抓到其他黑客使用蜜罐报复。

构建

我探讨了Solidity代码的逐点构建，以及Solidity最佳实践。

0. Hello World
1. Getters和Setters
2. 气体
3. 改性剂：纯，视图，其他
4. 溢出攻击

所有Solidity漏洞利用的列表：

• 下溢攻击
• 下溢攻击
• 可重入攻击
• 自构造攻击
• 拒绝服务（DoS）攻击
• 网络钓鱼攻击
• 隐藏恶意代码
• 蜜罐攻击/蜜罐报复

我还包括了攻击修复：漏洞利用修复和攻击修复。
