This is done through a new consensus algorithm between Bitcoin and the Stacks blockchain. The paper summarizes the Proof-of-Transfer (PoX) consensus mechanism at a high-level, the Stacks ecosystem, STX token economics, earning BTC from consensus, and even some future R&D areas. PoX consensus, the first of its kind between two blockchains, is a unique concept and is fairly complex so the full PoX whitepaper
remains the best place to understand consensus details.
I'd like to thank the Stacks community members for feedback on early drafts and several offers to translate the Stacks 2.0 whitepaper into international languages. Feel free to contact me @muneeb
for any comments or questions about the paper. I plan to make minor improvements to the in the coming weeks. The best part about the paper to me is that it's not merely a "design paper" but describes a system that's actually going live next month. → Read the Stacks 2.0 whitepaper
