Bitcoin Unleashed: Q3 2021 In The Stacks Ecosystem

“Dreams make good stories, but everything important happens when we’re awake.”

Duncan Idaho, Dune

A better internet on Bitcoin has long been the shared dream of the Stacks community. This quarter, though, saw its manifestations truly awaken.

As if you can't tell by the quote, I'm pretty excited for Dune. In some ways, Dune's spice is a good comparison for Bitcoin. Beyond its obvious use as a currency, it is a scarce resource that requires great effort to mine. Attempts to replace or replicate it are never satisfactory, it enables both thought and function not possible without it, and it is something still not yet fully understood, but which clearly influences the world around it in a major way.

And yes, it even enables space travel (way beyond the moon, too).

Herein lies the lesson from Dune: They embraced spice. They found ways to enhance and unleash it to serve everything from their health to their technology. This is what the Stacks community has been doing for Bitcoin since Stacks 2.0 launched.

In a little over 9 months, we've seen things done that have never been done on Bitcoin before. From NFTs that earn a BTC yield, to decentralized loans that repay themselves, Stacks and its builders have begun to unleash the full potential of Bitcoin.

Stackers, we're not just welcoming this evolution but driving it. Thank you for everything you've done and continue to do. For the rest of you, don't worry, we'll be here when you wake up.

Stay spicy,

Mitchell Cuevas and the Stacks Foundation Team
