        I don’t have these answers for you, it depends on the project. How do you know that the exchange you’re using buys bitcoin on the same blockchain as the exchange I use? Because they said so? When’s the last time you downloaded the whole blockchain for any coin and verified the whole sequence of blocks from the very first one? I certainly never have. But I regularly have the whole chain for git projects on my machine. Point is it’s the same data structure. Bitcoin’s innovation is in how blocks get added, but it’s not as revolutionary as it looks from the hype. Read the original paper if you don’t believe me, it’s very well written and incredibly approachable
