Sorry to jump into this conversation, I'm also interested about blockchain, I heard that term several time without knowing what ti is or how it work. Can someone just confirm if the following mental model for blockchain is correct please:

From what I have understood, blockchain is like a record of transactions (digital ledger) which are stored across several nodes (distributed network). Each node contain the same data, so it's difficult to modify things without realising it.
