Hey 👋
I am Américo Júnior, A young African passionate about technology and information security, I started studying programming and hacking at the age of 14, and today I work as an ethical hacker helping to make the internet a safe place.
This is my first post here, now that I’ve started a new journey, I’ve decided to start writing about what I’ve learned.
Earlier this year, i developed interest in blockchain security, and decided to focus on that, the first article I read was Hacking the Blockchain: Ethereum and i learned that to become a nice blockchain hacker, i needed to learn how to build application that live on blockchain, the famous DApps. I decided to focus on that, because it’s been a long time since I’ve only focused on the web, and all this time I dealt with pretty much the same things, I mean the same technologies, the same approaches, etc.
How I’m Starting I started learning blockchain development in january of 2022 with freeCodeCamp’s course, this course gave me a wide of blockchain development, i learned it:
- Advanced and effective smart contracts development with solidity
- Smart contracts deployment to blockchain and testing to with python brownie or web3.py
- How to run a local blockchain node with ganache
- ERC20 and ERC721 tokens creation
- Creation and deployment of NFT’s with Solidity
- Smart contract upgrading
- DeFi devolpment
- Interaction with Solidity contract using React.js
After the course, I read a good part of the ethereumbook which helped me to reinforce my knowledge about blockchain and I finished a good number of cryptozombies chapters to pratice my solidity skills.
Today, September 24, 2022, I started learning blockchain security, learned a type of vulnerability called reentrancy, watching the smart contract programmer channel hack solidity playlist video. In 1 week I will post a new article to update what I have learned.
As I said, this is my first article, in it I wanted to tell you how I’m getting started in blockchain security, so you can get to know my first steps. I hope you liked it, I promise to improve in the articles lol!
Goodbye!
