Hi, I was wondering how important is a fine synced time on an ethereum node. Are we talking about a maximum of a second delay to be able to interact with other nodes or is it more about micro or miliseconds or even nanoseconds? We mostly rely on NTP servers to have this time. NTP servers rely on atomic clocks. Atomic clocks are centralised. I see a spof here. If the maximum time shift is not so low, couldn't we find a more decentralised way to have the right time? Thanks.

Because they are too scared it ruins their reptation.

Hi, I wonder what part of all ETH are stored on mobile wallet apps. It's clear that it's easier to use and you're ​ready to make payment anytime without your computer on, but if smartphones are not safe to hold keys, what is the chance of having keys stored in a mobile wallet app stolen?

What could we do to strengthen security?

Do we have any software answers for that or any attempt are vain without a hardware security?

Some suggested to me that having the keys held by a secure server (like one in a bank) is the only secure way to proceed and having this server take care of making transactions with the chain is like having prepaid card or an actual bank account and banks are safe places.
