Mmmm.. this is not the same what i mean. Suppose i can access to my "wallet" (aka bank account) from any bitcoin client.. simply i insert my "user" and my "password"... because all "bank account" (wallets) are 'replicated' through all clients. This allow you not to loose all coins (money) if you format your pc or get a virus or ... Obviously, there are a risks to have your wallet 'cracked' if you don't use a strong password because anyone can access to all wallets... there are pros and cons to evaluate...

Do you mean *all clients* in the whole network? Or just a set of clients that you control?

No i mean all clients .. or some clients that you don't control.. Like a de-centralized archive's of crypted wallet. Only who knows password can decrypt and access to his wallet.

(Asked by: username_0 on 2013-05-26)

I was thinking about a possibility to overcome the 'only stored on one PC' wallet problem! I erase or lose my PC, then I lose all my bitcoins.

Suppose that the wallet, associated with an account number and a **strong** secret password were backed up on all Bitcoin clients.

What would be the drawbacks/advantages of this solution?
