Day 5: Blockchain Learning 🔐 Wallets = Private/Public keys + seed phrases 📥 UTXO model: spend entire output, get change ⚡️ SPV: fast tx verification w/o full blockchain Your wallet holds keys, not coins. Security = math + trust. #Crypto #Blockchain #Bitcoin #UTXO @rohit_negi9
Day 4 – Blockchain Learning 🔐 Double spend problem & prevention 🧾 Public/private key + digital signatures 📦 Block = header + data + Merkle Root 🌳 Merkle Tree for fast tx validation ⚙️ Nonce + difficulty for secure mining #Blockchain #Crypto #Bitcoin #Web3 @rohit_negi9
Day 3 – Blockchain Learning 🔍 How miners use Nonce to build blocks 💡 Why Proof of Work matters ⚔️ Honest vs Corrupt chains ✅ Mempool, longest chain, and validation logic Security = computation + consensus. #Blockchain #Web3 #Crypto #ProofOfWork #Nonce @rohit_negi9
Day 2 — Blockchain Learning Blockchain isn’t just tech—it’s trust, decentralized. → Shared ledger → Immutable records → No central authority → Bitcoin, proof of work, miners, hashing Redefining how transactions and trust work. #Blockchain @adityatandon02 @rohit_negi9 #Web3
Day 1 Blockchain Learning Barter to currency. Currency to crisis. Crisis to decentralization. 2008 showed why central control fails. Blockchain isn’t hype it’s a response. #Blockchain #Crypto #Web3 #DeFi #Fintech #FutureOfMoney #OpenToWork @rohit_negi9 @adityatandon02
