I was thinking about something i was missing in any crypto.
Cryptos are all based in same concept of security, where a private key sign operations. If the private key get compromised, someone could cleanup your account in seconds.
Right now, If someone get into my bank account and is able to order a transfer, i receive an email telling, a transfer was ordered at this time and will be submitted as soon as possible.
In some cases, real time is not required.
Could be useful to have a mechanism like a new options value, with a time amount and public key parameters, to delay all next operations for certain amount of time and a destination account as "emergency exit account". That means that when an transaction is submitted, it will be recorded but will not be effective for certain amount of time (or ledges), fee discounted at the moment of submit (as any other transaction)
If an account get compromised, the legal owner could execute a new operation that will take the destination account indicated before as "emergency exit" to merge the whole account . A transaction containing only this operation will be the only one ignoring the delay time.
Clients could be listening to fraud operations, if account get compromised, the emergency "button" could be pressed.
Just to remember, Tether lost 30M$ because someone hacked their system and accessed a private key. This system could prevent these things happening. And as it will be an option, everybody could choose to use it, and what amount of time of delay he requires.
