I think this idea might be the most practical use of blockchain and its immutability. However, Walton and WaBi are doing the exact same thing as far I can tell. Walton has a great team although it is all Asian-based so it might have trouble reaching global markets. I'm not sure on WaBi.

I think first to market will decide who wins this battle at least in the short term. Is Devery planning to try and beat these other 2 projects to market? Or how does Devery plan on competing with them?
