The last video (for now) on blockchain and supply chain.
A final piece of the puzzle is to irrefutably link the physical objects and participants to their digital representations on the blockchain (tokens and wallets). This is especially tricky in open blockchains, where authentication becomes extremely important.
I know of four main ways:
* physical unclonable functions
* QR codes
* RFID tags
* IoT devices
I discuss each of these in terms of its strengths and weaknesses, which are usually...

Do you have use cases for cheap passive RFID tags that can one-way authenticate?
I'm asking for help from my connections to come up with concrete uses for a cheap passive RFID tag that can perform one-way authentication.
Those of you who follow my videos will know that recently I invented and filed a patent for a blockchain-backed enhancement for such a thing. So far I have:
1. replace barcodes with a more secure RFID in open supply chains so anyone can report goods in transit, not just trusted partners,
2. replace IoT devices currently used to track expensive goods with...
