Hello, Bitcoiners! I would like to share with you my interview with Atlas21 regarding my dissertation on sustainable Bitcoin mining.🔥🚀

Bitcoin reduces emissions and consumption: the thesis published at the University of Salento
Jacopo Graziuso's econometric study explains how the presence of Bitcoin is connected to the reduction of emissions and consumption in

🔒 Who's really in charge of Bitcoin? Full nodes. 🌍 It is not the miners, nor the developers, nor the companies. In Bitcoin, the real power is distributed among thousands of complete nodes, software that verifies every block and transaction according to shared rules. That's why they're critical to the network's resilience and governance. 🧠 Nodes dictate the rules. - Miners propose blocks, but nodes decide whether to accept them. - Any node can reject non-compliant transactions or updates. Consensus occurs when the majority of nodes follow the same rules. ⚔️ Fork: when the rules change - Soft fork = compliant update (e.g. SegWit). - Hard fork = net split (e.g. Bitcoin Cash). 📌 Real case: in 2017, nodes forced the activation of SegWit (UASF), giving miners a choice: adapt or stay out. 🛡 Defense against attacks: - ✂️ Censorship? Nodes can reject blocks that exclude valid transactions. - 💸 Inflation? No block can create more BTC than expected: nodes will reject it. - 🕸 Network attacks? Nodes filter suspicious connections and protect traffic, even when using Tor or mesh networks. 💰 Nodes guarantee the 21 million limit. It's not enough to "write it in the code": only nodes enforce the limit by checking every single block. 🏛 Political and economic impact Thanks to the nodes: - No one can arbitrarily change bitcoin. - No one can control it from the top. - No one can violate its monetary policy. ➡️ Bitcoin is resilient because the nodes are sovereign. "Don't trust, verify" is not just a slogan, but an active defense mechanism. ❓️ What is a Lightning Network node? 📶 Stay tuned. #bitcoin #node #fork #attacks #political #economic image
🎯 How does a full node work? 💻 A full node is the beating heart of the Bitcoin network. It is software that downloads, verifies, and propagates every block and transaction without trusting anyone. Here's how it works: - 📦 Blockchain database: stores all blocks and the set of spendable bitcoins (UTXO set). - 🧠 Mempool: stores transactions waiting to be included in a block. - 🌐 Networking: communicates with other nodes to exchange data, blocks and transactions. 🔍 Each node verifies everything itself: - Transactions must be valid, correctly signed, and not duplicated. - Blocks must have the correct proof-of-work, be consistent, and comply with all rules. - At startup, the node downloads the entire blockchain from 2009 (Initial Block Download). - It then stays up to date with blocks and transactions in real time. 🔁 Connecting to the network Each node is connected to dozens of others, constantly exchanging information to keep the network consistent and secure. 🛡 User sovereignty A full node is not dependent on third parties: it verifies everything itself, protects against errors and attacks, and is the tool to truly participate in the Bitcoin network: Don't trust, verify! ❓️ Who is really in charge of Bitcoin? 📶 Stay tuned. #fullnode #bitcoin #user #network #blockchain #database #mempool image
