According to this article "[A gentle introduction to bitcoin](https://bitsonblocks.net/2015/09/01/a-gentle-introduction-to-bitcoin/)", it looks like a blockchain is created per Wallet.

Is this correct or am I misunderstanding it? If my assumption is not correct, what determines when to create a Blockchain?

"The blockchain" is the universal list of all Bitcoin transactions that have ever been confirmed.

A new wallet doesn't "create" a new blockchain. Rather, it downloads a *copy* of the existing universal blockchain. It does create some new files on its own computer to store the data it downloaded, but the data itself isn't new.

(This assumes it is a "full node" wallet. "Thin" or SPV wallets don't download it; they rely on other nodes to tell them what transactions already exist.)
