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?
We like what these other projects are doing but we believe a more open source approach would be beneficial to wider adoption. We have open sourced our protocol and will be working to build an ecosystem of developers and brands who build and utilise the protocol. Hardware integrations on our part will also be open, so that manufacturers of NFC chips, RFIDs, etc can actually build solutions using the protocol.
