You're viewing part of a thread.
Yeah, you would only need to have every single private key for all nodes that follow you in the supply chain. Super trivial.
OK. So you are proposing a private blockchain with minimal data validation rules.
How do you decide who gets to add the next record?
You would also need some protection against all nodes sharing their keys.
It's not a blockchain. It's closer to a series of forwarded emails with certificate signing. Who gets to add the next record? How about the party that is doing that step of processing in the supply chain. And I have a great idea for protecting the keys. It's called asymmetric key pairs. You can verify a signature using a public key without having the private key required to be able to generate that signature.

You've got hash linked data, signatures, verification procedures, distributed storage. It's not very sophisticated, but you are definitely on the path to reinventing the blockchain.

Oh, so you want a new database for every item. Let's have one database handling lots of items and validated in sequence.

Brilliant. And how is your invention different from a private permissioned blockchain?
Blockchain is the shitty reinvention of PGP, my dude. I don't agree to this silly retronym for nearly 50 year old cryptographic methods. Yes, if you remove all the supposed advancements and advantages of blockchain, you're left with the cryptographic foundation which was the only thing that had merit. Congratulations.
Yes. Blockchain is PGP + Hash linked lists + Distributed validation. They hadn't been combined until 2008.
