I'd just like to check it's integrity so basically download the blockchain and THEN put the wallet.dat to only expose it for a few second.
Also i would love to do it on my ubuntu livecd but i'm not sure if this is even possible.
any idea?
You probably have several options (more than one way to skin a cat). The first that comes to mind is:
- Set up a brand new empty wallet on an online computer and wait for it to acquire the full blockchain.
- Copy the blockchain files onto removable media
- Boot an offline computer from your liveCD
- Install Bitcoin-Qt on the offline computer
- Copy the blockchain files from the removable media onto the offline computer
- Copy your wallet.dat from the removable media onto the offline computer
- Run "Bitcoin-Qt -rescan" from a command line to force Bitcoin-Qt to rescan the blockchain using the keys/addresses from the wallet
