Currently, if an attacker gets the alert key or otherwise compromises the alert system (by breaking SHA-256, for example), he can prevent all alerts from being displayed by sending an alert with Cancel=INT_MAX.

It might be a good idea to define a special alert (maybe one with a signature but no body) that would never expire under any circumstances and would display a generic pre-written message telling the user to upgrade and not accept transactions.

I'm intrigued by this alert system. Could you point out in the code where this is? I browser the whole code base a week ago, and couldn't find anything.

Search the code for "CAlert".

:tongue in cheek:

had to be the first to ask it - but what happens if the alert alert system is compromised? Smiley  Do we need an alert alert alert system?

It would be fixed in the next version. There just needs to be a non-revocable message to tell people that they need to upgrade.

I must say this is one of the wildest things I've ever read about Bitcoin! Could someone give a short description as to how this machinery would work? Inserting a special transaction in a block, with a message signed with a special key only owned by someone (Satoshi, I assume)?
