Bitcoin capital is coming home. Let's do an ultimate stacks refresh 👇 Image 2/16 What is Stacks:

A smart-contract chain that anchors every block to Bitcoin L1 via Proof-of-Transfer (PoX). You get Bitcoin programmability; miners bid BTC, STX stakers earn 8-9% BTC yield. Image

1/ Many asked for an sBTC OP_DROP deep-dive, here we go 🧵 2/ Important context: sBTC is a decentralised BTC peg secured by @Stacks consensus. Moving BTC to sBTC is a peg-in

OP_DROP is a mechanism by which to format a peg in, in addition to OP_RETURN (another mechanism by which a peg-in can be formatted)

For many, DeFi is a black box. We need more DeFi literacy on @Stacks to inspire the great builders we have to build exciting protocols.

I'll do a few threads on fundamental concepts and share hooks for interesting things to build

Let's start with Impermanent loss 🧵 With the @alexgoBtc launch, we get a new DEx on Stacks to provide liquidity (LP) to to farm sweet APYs.

But, when you LP on an AMM you lose some of your tokens due to impermanent loss. Sounds scary..

I think DeFi on Bitcoin is the biggest lever to grow crypto. Why? 👇 We need property rights on the internet for a good future. Crypto does this.
