Add chapter about using native Bitcoin

[friedger]

Does it make sense to include a chapter how to use native bitcoins in clarity contracts? Or is it out of scope

The chapter should explain

• what state of the bitcoin chain clarity contracts can view
• where clarity-bitcoin library is deployed on mainnet and how to use the contract
• which contracts and applications use clarity-bitcoin (catamaran swaps, magic bridge, zest protocol, bitcoin faces/nfts)

Yea I agree , I think this info should be on plenty formats and on several levels , websites , clarity book also 🦴🦴

Sounds great to me. Are you suggesting you will write that chapter? 😉

When it comes to the last point:

• which contracts and applications use clarity-bitcoin (catamaran swaps, magic bridge, zest protocol, bitcoin faces/nfts)

Right now the book does not really refer to any project so it would be a stylistic break. However I think a whole chapter with case studies / looking at various projects can make sense. Still, up to the community, the book is for everyone.
