Blockchain.Info Privacy, Double Encryption and Escrow questions

[PilotofBTC]

I have few question about blockchain.info's My Wallet. (Yes I've read the help).

First, on the privacy page it states that if you want Alerts/Notifications you "expose" your Public Key to Blockchain.info. What are the ramifications of this? Does that identify me in some way on the block chain? Does someone getting my public key mean they can look at all my transactions at every address?

Second, double encryption...

I am assuming with a single password, that password is the key use for the wallet encryption as well as the credentials needed to be able to d/l said encrypted wallet so that the Javascript is able to get access to my private key to sign transactions/messages.

When I add a second password, does this mean the encrypted wallet is encrypted again before it is stored at block chain info. Or, does this mean rather than the wallet being encrypted with the main password it is now encrypted with the secondary password and the main password is only used as a credential to be able to access the encrypted wallet?

wrt 2FA. Is this only use for logging into the web site. Or is it also used to spend coins? Rather than a second password, I would rather have to enter the 2FA code before sending. ALthough, I assume that would only work with BlockChain, and if my wallet (private key) was compromised someone could import it into another client and spend my coins without needing the 2FA code at all.

Finally Escrow. There is a second in the Help about Escrow but it doesn't go to a help topic. Does Blockchain.info have an escrow feature?

you pretty much know it, seems like your educated guessing was getting it right every time

do yourself a favour man and don't use a hosted wallet, well not for for more than 50% of your funds anyway or something like that

For sure this will just be a hot wallet for transactions. I am just getting to the game. As I acquire more for long term holding I will be putting it into paper wallets.

But, realistically, what is the risk of having the encrypted wallet store online at blockinfo vs on my PC? Assume someone gets access to blockchain.info and d/l's the encrypted wallets. Since they don't store the passwords, it is up to the attacker to brute force break the encryption. By that time I hope that blockchain would inform everyone of the incursion and I would have time to quickly transfer to a paper wallet ready and waiting, create a new wallet somewhere and import the paper wallet into it. (Yes I'm sure this has been discussed here alot). So, no need to answer in this thread.

I'm not sure if blockchain.info has their own built in escrow but you can use a trusted one from here.
