Last but not least: → Chaining Each block holds the previous block's hash. Tamper with one and the whole chain breaks. Fraud is mathematically visible. No trust in a person. Just math. #blockchain #web3 #100DaysOfCode 3/3

How does blockchain enforce trust with no central authority?: → Distributed ledger Thousands of nodes hold identical copies. No single point of failure. → Hashing Each block gets a cryptographic fingerprint. Change one byte and every node rejects it. That is immutability.

Day 1 of learning blockchain and it starts with the most important question: Why does blockchain even exist? The answer: centralized systems have 3 fundamental failure modes that affect billions of people. 🧵 1/3 @CyfrinUpdraft @tgmweb3institut @X

@CyfrinUpdraft @tgmweb3institut @X ③ Censorship Traditional banking creates a paper trail. Governments can monitor and block transfers. Crypto eliminates that entirely. Blockchain's fix: remove the middleman. 2/3

@CyfrinUpdraft @tgmweb3institut @X 3 problems with centralised systems: ① Control One org can freeze your assets or block transfers at will. Your money is not truly yours. ② Exclusion No fixed address? No bank account. Millions locked out of the global economy.

Today, we celebrate the hands, hearts, and minds that build our world, the everyday heroes who put in the work. Your efforts make a difference. We honor your passion, resilience, and strength. Happy Workers' Day! And Happy New Month ✨

You didn’t get here by luck. You made a decision to grow, to stand out, and to step into the future of Web3 with intention. This journey won’t always be easy, but it will be worth it. So if you’re ready to: 🔥 Show up 🔥 Put in the work 🔥 Build something real 🔥 And become part of something bigger than yourself Then let’s hear you loud and clear 👇 Drop “READY” in the comments if you’re locked in

Day 1 of my Web3 journey 🚀
Today’s intro covered blockchain, its pioneers, and decentralization. I learned the difference between coins and tokens, and how wallets like MetaMask and Phantom power identity and transactions in Web3. Excited! @TheColetteOziri #Web3‌‌

A DNS record is like your phone contact list for the internet. Instead of remembering numbers (IP addresses), it stores the correct “number” for a website name so your browser knows where to go. It tells the internet what to do with a domain name.

@only_Lawrence Happy birthday lawrence 🚀

Happy birthday to me 🎉🎂🥳

Finished Cisco Networking Basics today 🎉 Subnetting almost won… but we move 😅 Foundations locked in.@cyber_razz @elormkdaniel @T3chFalcon Next step: applying this knowledge and going deeper into blue-team / SOC skills. #Cybersecurity #Networking

Network testing tools don’t “fix” problems. They tell you where to look. I realised that while working through Cisco’s network testing module. The real skill isn’t running commands — it’s knowing what problem you’re trying to fix. Building that habit early. #CyberSecurity #SOC

Application layer services done. Understanding how DNS, web, FTP, and email, SSH and telnet are supposed to work makes it easier to spot when something doesn’t. Building the baseline for cybersecurity early. #CyberSecurity #SOCAnalyst #Networki

Learning Python has been surprisingly fun so far. Alongside Programming with Mosh on YouTube, I’m also using codedex to round things out and get a more well-balanced learning experience. #codingtillIgetajob #learningpython #SoftwareEngineer #softwaredev

Day 1 of rebuilding my foundation in Computer Science. Starting from the basics, no shortcuts, no rush. Focus today: fundamentals, problem-solving, and thinking like an engineer. Let’s see where consistency takes me 🚀🚀

@Horiyourme May I ask what the minimum amount I need to start stock trading, and what platforms and app we can use to snipe foreign stocks.
