Everyone talks about how Lightning works.

Almost no one talks about why Lightning is hard on mobile self-custody and how @Liquid_BTC + atomic swaps help. ⚡💧

Let’s go deep. 👇 @Liquid_BTC Lightning is a major technical achievement:

⏱️ Near-instant settlement
🌐 Off-chain payments
🔁 Bidirectional channels
🗺️ Routing across a global graph

It works brilliantly. But the engineering model introduces new responsibilities. ⚙️🧠

Everyone knows what #Bitcoin is. But almost no one understands how it actually works.

A brutally elegant system engineered to remove trust from money.

Let’s break it down. 🧵👇 Bitcoin solved a problem older than the internet:

“How do you send money online without a bank preventing double-spending?”

Before Bitcoin, this wasn’t possible, every digital payment needed a middleman.

Bitcoin replaced that middleman with math + incentives.

You thought #Bitcoin transactions were final once you hit send?

What if I told you… you can “edit” them? 👀

That’s what Replace-By-Fee (RBF) makes possible. 🧵👇🏻 💡 What is RBF?

Replace-By-Fee (RBF) is a #Bitcoin feature that allows the sender to replace an unconfirmed transaction in the mempool with a new version that pays a higher fee.

Until it’s confirmed in a block, a TX isn’t set in stone.

What are UTXOs? And why does it matter in #Bitcoin?

If you've ever used Bitcoin, you've interacted with UTXOs, even without knowing it.

Let's understand it simply and correctly. 👇🧵 1⃣ UTXO stands for Unspent Transaction Output.

In other words: It's like the “change” you received in a previous transaction, which you can now use as “input” in a new transaction.
