Parmigiano-Reggiano makers are putting edible microchips the size of a grain of sand into their 90-pound cheese wheels to combat counterfeiters::Italian Parmigiano-Reggiano makers are using microchips to verify the authenticity of their products and thwart scammers.
and much more… centralized? But let’s also just ignore the part where it’s described as generally more secure as well.
Most commercial non-crypto blockchains I’ve seen only have a couple of nodes connected, usually held by a single entity. In these cases it’s no less centralised than any alternative write-only DB.
The cheese makers are not concerned about decentralization. Presumably they trust themselves, because they are the only ones trusted to write to the database. If they are the only ones allowed to put something on the chain, it’s a central database, regardless of how many computers/places they run it on.
Blockchain is not magically more secure than any other equivalent cryptographic solution.
