If (there are trackers for supply chains already)
then { blockchain is surely better because it is immutable and can have multiple validators }
and there are trackers for supply chain already run on centralized databases that can be tampered.
- theamk 8y agoYou don't need blockchain for immutable log with multiple validators, you just need system like the one Certificate Transparency does [1]. It looks pretty similar to blockchain, but it has lots of advantages for supply chain tracking: much better scaleability, no energy waste, no need for full chain, ability to only care about specific subset of entries, and so on. There are a number of current CT servers, and they are generally free -- they are so cheap that a large company can run one as a public service. For supply chain, have a few competing companies and govt's of US, Russia and EU run it, and you would have very tamper-proof system.
