Someone correct me if I'm wrong, because from what I've read, there was no such thing as a blockchain before Satoshi introduced bitcoin.
You're absolutely correct that blockchain technology was introduced by Satoshi. Blockchain and Bitcoin are two different things though because Bitcoin is an application/system that uses blockchain technology.
The blockchain technology is highly rated by even bitcoin naysayers because it can be used for countless purposes.
bitcoin is just an application of a blockchain, so I'm not sure what you mean by your second sentence there. I just came to this thread to help out a member with a post history review but started reading other posts, and man....this section is going downhill fast.
I think he means that if Bitcoin was not introduced we won't have the blockchain technology. I guess he meant something else and ended up meaning something else.
If Bitcoin didn't existed, there won't be a blockchain, If the blockchain didn't existed we wouldn't have Bitcoin. Does this make sense .. haha even I am confused now lol.
