Hello @Xynerise,

I'm really sorry for my late reply.
Thank you very much for your answers. It is enlightening

Hello everyone,

I eventually read Satoshi's white paper on bitcoin but I am still asking myself some question about the technical design of the Bitcoin blockchain.
I know the answers must be somewhere in this forum but I could not find them.

Here they are :

- How is possible to find/verify a transaction thanks to the Merkle Root hash ?
- Where are the old blocks and transactions stored ?
- How do the minors decide whether a transaction is legit before adding it to the block ?

Thanks a lot for your answers.
