Who would want their ownership tracked on a public ledger? And what happens when people forget about or don't care about tracking the transfer on the ledger? Also there's still plenty of people to sell fakes to since not everyone is going to verify the authenticity.
- iV7B53CmgHjB 5y agoHaving ownership tracked on a public ledger does not imply it needs to be associated with a real name, just a key.
- beforeolives 5y agoAren't you sharing that key with anyone that you transact with?
- 11thEarlOfMar 5y agoThis could be useful in the semiconductor industry, for example. We are currently battling with marginally performing chips that were sold out the back door to brokers. A traceable ledger inform us whether a lot we purchased from a broker had a chain of ownership back to the front door. This evidence would do a lot to ease our customer's concerns, and having the data public would be a plus.
- pests 5y agoWhy a blockchain though? How about a database the chip makers can update when they make a new chip, and a public forum showing latest chips made and a lookup to ensure chip authenticity? What does making this distributed or trusting others have to do with anything?
- 11thEarlOfMar 5y agoCounterfeit chip makers could simply look up the chips and re-use the serial numbers? The idea is to use a chain of purchase records (purchase orders and invoices) to ensure that each transaction is recorded and unique, with the first transaction in the chain entered by the manufacturer.
- pests 5y agoThe physical product has to be linked to this chain of purchase records tho. How do you tell, given just a chip, that it has a corresponding chain of records? Whatever solution you give me, what stops counterfeiters from reuse as well?
- 11thEarlOfMar 5y agoThe business processes of the companies involved in each transaction would ensure the keys/tokens were associated with a physical inventory under their control. MRP systems can manage the warehouse & inventory. The chips themselves don’t have to be marked.

- _fizz_buzz_ 5y agoThe problem still exists. You cannot permanently fix a digital certificate to a physical object. If I buy a real chip and a fake chip, I can still reattach the certificate to the fake chip and sell it to you and keep the real chip.
- noahatwi 5y agoConsidering that the biggest reason to buy a lot of these luxury products is status, it seems like many people would want their ownership tracked.
