RE: Old wine in new blockchains
If they do it the VeChain way; then the blockchain trail will start right back at the picking stage. Reading into their ideas for e.g. making sure the cold-chain is not broken for frozen foods is fascinating. Smart RFID chips with inbuilt sensors enable checks and balances all along the way, and all visible on the blockchain. I think blockchains can and will make a big difference to this sector.
Indeed, would you also consider WABI as a good technology ?
Not bitbrain but I'd say no: WABI, WALTONCHAIN and possibly VeChain, 3 Chinese "blockchain" company, 1 problem: their blockchain solution doesn't eliminate trust thus doesn't require a bockchain. (imo)
I do not know if talking about it made it pump but it is gaining 46% right now.

I have to be honest, I have not looked into WABI yet and therefore any comment that I may make on it at this stage would be an uninformed one.
How does VeChain make sure that no junk goes into the blockchain exactly @bitbrain?
I doubt that you could ever fully protect against it. I think, and I'm not an expert here, that the VeChain method relies on automated smart sensors which record (and possibly log, I don't know) data onto the chain, combined with a set of trusted individuals who know how and where to read data in. They follow products from start to end i.e. from harvest/manufacture to the final point of sale, logging all major data along the way. I hope that sort of answers your question; sorry I'm not specialised/knowledgeable enough to elaborate further.
Sure, no problem, not an expert on the technology but, based on what you're saying, it sounds a lot like this application doesn't really need a blockchain:
oracle problem: again how do you make sure that the data that comes in is not junk.
this one speaks for itself, if at the end of the day you're going to rely on trust then a blockchain doesn't seem to be necessary, but as I said I am not familiar with the finest points about this technology.
