GOOD MORNING!

the looters will never know peace.

🔐 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.

You are sheltering spam in your mempool, are you knot?

Cat and mouse games sound futile, until you realize that you catch a lot of the mice.

Spam apologists trying to reintroduce the Bitcoin censorship FUD painted with jargon to confuse people. Sigh

Spam filters cannot be abused for censorship. It only takes 1 block to bypass attempts to censor. But it takes 1 block to make spam filters effective. Opposites.
