It's an open-source project with 4 years of research and development behind it. The architecture implemented here is actually inspired by David Clark (Chief Protocol Architect of the internet) and his new design principle, called trust-to-trust design, that aims to fix critical security issues with the current design of the internet.

I agree that rebuilding everything is hard and that's why we reuse not only TCP/IP and everything below TCP/IP in the stack, but we also reuse existing infrastructure in a decentralized way.

We've already built this stack and have been running it in production for 3+ years. Please see our peer-reviewed research papers and our whitepaper at http://blockstack.org/papers for more details. Happy to answer any questions!
