Title: Electrum - Master Public Key ? Post by: The Bad Guy on February 10, 2015, 07:31:12 PM Hey there,
i've been wondering what is that Master Public Key used for exactly , since I've seen it used on some WordPress e-Commerce plugins I would like to know what is it useful for , and is it possible to share it or it's something like Private keys and shouldn't be shared with anyone . One more question is should I take it as backup or there is no need for that and only the seed is helpful Title: Re: Electrum - Master Public Key ? Post by: The Bad Guy on February 10, 2015, 07:38:10 PM The master public key is like a seed that only allows you to figure out the Bitcoin addresses in your wallet, but not the private keys. Those wordpress plugins you saw use the MPK to get deposit addresses. A bad guy with your MPK can only figure out your Bitcoin addresses, but not your private keys so they cannot steal your Bitcoins. However, if the bad guy has your MPK and one of your private keys, he can then calculate all the other private keys and steal your Bitcoins. This is the reason you should never export private keys from electrum. Oh , I see now , everything looks clear now to me . Thanks for the explanation mate , really appreciate it . It was just a quick question so going to lock the thread now :) thanks again dude |
