I recently spoke to my long-time friend and web3 founder @karan_pujara.
Some lessons about working in #web3:
🐻 Staying resilient during a tough bear market. I left my own startup and got fired along the way.
💻 Navigating #tech without a degree
👩💻 What is #devrel?

Learn more about what I'm working on now with the Internet Computer by following @dfinity and @DFINITYDev.
🎙️ Unlocking Career Opportunities in Web3 with @JKim_Tran, Devrel at @dfinity Foundation!
We delved into:
💡 Tech Beyond Degrees.
👨💻 Role as a Devrel in Web3.
🌐 ICP ecosystem and how ICP plans to enable fully on-chain DApps.
🤝 Community contribution matters a lot.
#private and public keys are a #Cryptographic system that allows users to securely send and receive transactions on a #blockchain network.
Private keys are unique identifiers that are only known to the owner. They are used to sign transactions and prove ownership of funds.
Public keys are generated from private keys and can be shared with others. They are used to verify transactions and send funds to a specific user.

#CCTechschool #blockchain
Orphaned Blocks in Blockchain.
When two different blocks get added to the blockchain at the same time by different nodes.
Whichever #blockchain length is big or having high hash power will win and the block that is different added by the other node will get cancelled and it went back to mempool. That block is called the Orphaned Block.

A consensus protocol is a set of rules that computers in a blockchain network follow to agree on the state of the #Blockchain
This is important because it prevents attackers from adding invalid blocks to the blockchain or tampering with existing blocks.
One common consensus protocol is proof of work. In proof of work, miners compete to solve a complex mathematical puzzle.
The first miner to solve the puzzle gets to add the next block to the blockchain and earn a reward.

How #Mining works:
Miners try to guess a nonce that generates a #hash below a certain target hash
If they guess correctly, they add their block to the #blockchains and earn a reward
Nonce, which stands for "number used once," is a key part of the blockchain mining process.
It is a 32-bit number that miners use to generate hash values for new blocks.
For more details about Mining and how block gets added to the blockchain check the below video.

The Power of Distributed #P2P Networks in #blockchain Security
In a distributed P2P network, all computers are interconnected, sharing the same blockchain. When one computer adds a block, it replicates across all connected computers.
If a computer is hacked and its blockchain altered, the network's design constantly checks for blockchain consistency among peers.
Peers quickly identify a hacked blockchain and automatically copy verified values from other peers to restore integrity.
Check out the video below for more understanding of the P2P network

The Power of #Immutable Ledgers in #blockchains
When you buy property, documents define your ownership, and registered with government authorities.
Traditional ownership records can be tampered with or deleted, leading to disputes over property ownership.
In blockchain, ownership entries are secure. If someone attempts to change ownership data, it alters the block's hash, creating a mismatch with the previous block.
Blockchain's immutability prevents unauthorized changes, ensuring the integrity of ownership records.

SHA256 is cryptographic hash function that produces a unique 256-bit fingerprint for any digital data. It is one of the most widely used hash functions in the world and is used in a variety of applications, including blockchain, digital signatures, and file integrity verification
- A small change to the input data will result in a large change to the hash value.
- You can not restore the digital document or anything based on the hash value.
- If I take the same document copy of the other document. And I apply the hash algorithm. It will give me the same hash as the hash of the original first document.
Check out this video for a more detailed understanding and practical examples of SHA256:
