You don’t explain why I should trust this over a regular boring SQL database. Let alone exactly what the actual problem is that is addressed here.
“Supply chain transparency”, sounds fancy though.
The problem is that the data must come from somewhere and blockchain can’t guarantee that the data is valid, only that it hasn’t been tampered with. We can assure that with less energy intensive solutions, no blockchain stuff needed.
And we know how well smart contracts (code is law) are doing.
Trust can never be replaced with technology. Trustless is bullshit.
- SubiculumCode 5y agoYou hadn't asked. But since you do now: Using Vechain as an example: Immutability is the difference and it’s what matters the most when building parts for products because it provides an unchangeable audit trail verifying the quality/parts of a product. But don't get me wrong, there may be better centralized SQL solutions, but the market will decide, won't it.
- louwrentius 5y agoThe marked may be full of idiots, I don't care. It's the concept that is ridiculous, a solution in search of a problem.
- SubiculumCode 5y agoOver 30 companies within the Fortune 500 have live solutions running on VeChain including Walmart, BMW, LVMH, Renault, Deloitte, and PwC. They are obviously interested enough to to examine costs and benefits of the system.
- ac29 5y ago> it provides an unchangeable audit trail verifying the quality/parts of a product How? How does the blockchain verify, for example, that the electronic parts used to build my widget aren't inferior quality counterfeits with lower lifespans?

- acdha 5y agoIn other words, it doesn’t. The real work is being done by the trusted auditors who verify that the NFC tags are legitimate, have been attached to a legitimate product, and remained there all the way to the consumer. If you don’t have that, you’re still vulnerable to all of the common attacks businesses have been fighting for aeons; if you do, you don’t need a blockchain.
- SubiculumCode 5y agoWell, yes any system is going to have multiple actors, and you can, if you want, say where the "real" work is being done. It is still the case that the record of NFC codes will be in an immutable database (the chain), which is much more than the current supply chain does.
- acdha 5y agoThe point is that blockchains are very expensive. When, as in this case, there are no benefits to using it over basic PKI or even tradition audit structures, it’s unlikely to succeed long term against more efficient competitors.
- SubiculumCode 5y agoWell, in the case of today's byzantine supply chain solutions, we've had a lot of failures, and I do not mean the current events. I mean that there is a lot of fraudulent products with no way for end users, or even final step-manufacturers to even know what is in their product. With Vechain, and consumer can look up the complete immutable record of every piece of his product, chip, board, screen, etc, signed by each supplier. Also, blockchains are not that expensive once you move past proof--of-work.
