Building on the blockchain isn’t magic It starts with basics: •pragma solidity to define version •contract to build logic •structs to create new types •arrays to store data #Ethereum #SmartContracts
Still learning Solidity day by day. Today I deployed and tested another smart contract on Remix Ethereum IDE From pragma solidity to structs, arrays, and view functions —> each line of code makes blockchain development clearer. #Solidity #Web3 #Blockchain
Decentralization Blockchains aren’t secure because they’re perfect….. They’re secure because the majority rules Every node checks blocks. Honest chains grow stronger, malicious ones get rejected. That’s the power of decentralization #Web3 #Ethereum #Crypt
Hashing & Mining Ethereum doesn’t use SHA-256 like Bitcoin… it uses Keccak-256 1. Hash = unique digital fingerprint 2.Mining = solving a puzzle (find nonce → hash with leading zeros) 3.Block = transactions + nonce + prev hash → new hash #Web3 #Python #Blockchain.
