I have done some research yesterday about the current state of smart contracts and NFTs on top of the Bitcoin blockchain.

So far I found two projects that are bringing smart contracts in the Bitcoin space: Stacks and Sovryn.

Stacks seems ahead of Sovryn regarding his development and funding at this time. I even found a functionnal NFTs marketplace in the Stacks ecosystem. Both projects have their own tokens: STX (Stacks) and SOV (Sovryn).

I'm curious about the technical and financial side of Stacks and Sovryn. Therefore, I would love to hear your opinions on both those projects.

I would also like to experiment with NFTs tied to Bitcoin and I'm not sure which marketplace is the best and the most popular. Any tips on that would be very appreciated.
