Not supply chain related, but a couple of real-life application blockchain projects I like are:
ACAT (Alphacat) - using AI & Big data to forecast crypto prices and also made available for small (not big financial firms) players. Best whitepaper, business model, and "gap" fill in the cryptospace (IMHO).
SRN (Sirin Labs, on my top 10 list) - have a blockchain focused/enabled smartphone and desktop computer with segregated cold wallets integrated. Products coming to market real soon.
Although both are available only on select exchanges, their prices are a real steal at the moment with huge upside potential.
Let me know any thoughts you may have about these, if so inclined.
