I have a few questions and suggestions regarding Armory below.
1. If I restore from a paper backup, will all previously used addresses that have transactions be automatically regenerated, or would I need to click Receive Bitcoins 50 times?
2. If wallet transactions are off, would I need to rescan databases, or will an option to rescan an individual wallet be added (like with lockboxes).
3. Which of the following would be most secure? A 7/7 lockbox, 1/7 lockbox, regular bitcoin address? Please explain why.
4. Can the ability for the creation of 1/1 lockboxes be added? For example to add vanitygen addresses but can't because the minimum is 1/2.
Thanks in advance!
1. Armory will search ahead some number of addresses. It should find them all unless you skipped a big block of addresses. You can generate more addresses manually from the Wallet properties window in expert mode. If you click on the number of "Addresses Used" you can scan more.
2. You would rescan the database
3. 7/7 fails to protect you against losing one of your fragments. 1/7 fails to protect you against someone stealing one of your fragments. In both cases you increase the odds of that happening. I think both options are worse than single unfragmented backup.
4. Lockboxes must be 1/2 or greater. We have no plans to change that.
