During last month we heard a series of news about exchange hacking ~

this is not new! it has been happening ever since first exchange opened up. and for the past couple of years we have at least half a dozen major exchange hacks some of which lead to that exchange closing down.

This thread is open to discuss about how exchange hacking can been prevented or minimize with the aid of Blockchain.

the two aren't related. centralized services can do whatever they want. the usage of "blockchain" will remain the same whether or not exchange are safe.

My first suggestion is that there should be a special protocol for generation of wallet addresses used by exchanges. This addresses should have an attributes and methods of preventing hackers from moving fund. Each mining node should act as police that will always check for malicious attack on these address by blocking movement of large amount of BTC from any address own by exchange and verification should be done before such move.

that would introduce restrictions at protocol level and will cause more damage to the whole system rather than helping anything. this is also on the end of nullifying the censorship resistance attribute of bitcoin. not to mention that what you call "verification" is impossible because the verification is the signatures that exist in each transaction which indicate the spender owns the keys, any other additional "verification" would require the same cryptography technique and keys which can also be stolen the same way the first one was stolen/hacked.
