Orchid Protocol, BlockMesh and RightMesh are all based on Ethereum, ERC-20 tokens and smart contracts. NKN will have its own blockchain technology that will have fundamentally new Proof of Relay and new consensus algorithms that will be newly developed specifically for tokenizing the network transmission capabilities. Our core developers are going a bit extra nerdy here. And if you are technology details oriented, you are welcome to read up on Cellular Automata and Conways Game of Life. :-)
