Has anyone tried using blockchain tech to check a tangible product's traceability and how is it effective?
I've honestly haven't tried one yet but I do believe that blockchain can excel in that area, considering that no one can just fake things here. LuxTag does that for tangible products to make sure that it's legit and they are using Symbol blockchain to keep things streamlined and cost-effective. Very interesting that they can maintain their branding/app name and still use all the benefits of Symbol too.

Can this be applied to ALL industries? Ecommerce, Food, Jewelry, etc.?
Yes, actually the blockchian has come to change the ways things are being done on many sectors of the economy of the world and I think this is just the beginning of good things to come. Obviously, the Blockchian has affected all most all part of the economy positively. For example,
In my own opinion, the Blockchain has bridged the gap between buyers and sellers by reducing the interference of third party intermediaries. The technology, in the form of Blockchain wallets, have eased the process of peer-to-peer payments.
Again, the Blockchain technology has also proven to hold potential to change the landscape of public transportation and ride sharing economy
Other notable area that the blockchian has played a big roll include, Banking and financial services, Real estate, healthcare, Agriculture etc.
