The blockchain was not invented from scratch by Satoshi.
The concept dates from 1982 or 1991 depending on what you want to credit as true blockchain and there is one running 13 years before Satoshi:

Very interesting.

KSI is a centralized system that encrypts data inside of its servers using customer-held private keys. I guess you could call that "blockchain" but it's not the blockchain concept most people are aware of today.

For me, KSI actually underscores how much the post-Satoshi approach to blockchain (decentralized) does not work. I already know this based on my experience with high-scale architecture, but this is yet another piece of empirical evidence.
