🔐 OP_RETURN in Bitcoin Core lets you embed small pieces of data (like a message 📩) directly into the blockchain! It's often used for proofs, metadata, or tagging transactions. The data is unspendable but permanently stored. In the example, we added a simple "Hello World" using hex 🔧.
👨💻 Requirements: Bitcoin Core, some BTC, and basic CLI skills.
🔥 Tip: OP_RETURN outputs are limited (max 80 bytes) to prevent blockchain spam.
