Title: Will old wallet versions forever be supported?
Post by: misterwhite on August 04, 2016, 10:46:51 AM
Hi,

I have an offline wallet with wallet version 1.35. Will this forever be supported by all future Armory versions? I plan to keep this wallet offline without touching it for many years, and I dont want to worry about new software will not be able to open it.

Thanks!

Thanks for you reply. Now I can sleep well at night! :)

By the way, where can I read about wallet formats and future wallet formats? I want to make sure I understand how everything works and right now its like magic for me.

The old format doc should be somewhere on the old website. Otherwise read the code. I'll document the new format as I implement it.

This kind of info would be very nice to have on a website dedicated to the opensource version of Armory you are developing. I cant seem to find a website, only a github repo. Do you plan to create a website? I can help contributing if needed.

When I have time for it. This is far from the top item on my list.

Looks like the old site is back online.

The old format link is here (https://www.bitcoinarmory.com/images/ArmoryWalletFile.png) with text here (https://www.bitcoinarmory.com/wallet-format/).

I think the format would be improved if it was split into two. 

The current system encrypts the wallet when new meta-data is added.  This can lead to file corruption.

Each wallet should be two files.

  • Root master key
  • Wallet read/write data

Both would be encrypted, but the root master key file would be 100% read only.  It would never change.  If you generate 100 new keys, they would be added to the 2nd file and only cause that file to change.

Back when I was playing around with testnet coins, generating 1000+ keys could cause Armory to crash.  Killing the process could cause the wallet to end up in a corrupt state.

You could make it so that each wallet is a directory containing both files, if that is more tidy.
