I recently installed Bitcoin-Qt on my laptop and it started performing the synchronisation with the network since a couple of weeks. And it's not finished.
Why do the Bitcoin-Qt application have to do so? If I am right, this application is just a Bitcoin client... I mean, it have not to check transaction integrity such as a miner, right?
Also, I would know if according to you, in 10 years (with some imaginations), having a lot of transaction every days, this synchronisation could take some months or even more.
Thanks for your lights!
