I've often discussed this with other supply chain blockchain crypto investors, I think that using a non decentralized private blockchain like Hyperledger is just a stepping stone for these big brands, they are trying the product in a controlled environment, developing the smart contracts and all the things they need in Hyperledger which is based on Ethereum when they see that it is indeed a better system they will, sooner or later, step it up to a public blockchain, since they already have the smart contracts and everything done they just need to port it to the new blockchain which is normally quite easy since many blockchain provide the tools necessary to do it.
Now I wonder how QLDB will be used and by who...Did they say why they called it Quantum? Or is this one more of the many products where big companies glued Quantum to sell it for an increased price? They could have named it Quantum AI blockchain ledger database and sell it for 4 times the price 😂
I remember an article a while ago about a company who rebranded by adding "Blockchain" to their name and that's it and their stock went up 25% overnight.
