Title: Electrum need backup? Post by: Allphonic on August 30, 2014, 05:03:23 PM I installed electrum and I saw the passphrase stuff at the beginning.
Now, if I lose my computer and install electrum on another one, will, by simply typing this passphrase, restore ALL my wallets, including extra addresses generated after the first setup?

It's a seed, and yes, by entering the seed, you can restore everything. Title: Re: Electrum need backup?

I dunno if that was supposed to be ironic, but you can still set up your own Electrum server if none are available. Title: Re: Electrum need backup?

Title: Re: Electrum need backup? Post by: Allphonic on August 31, 2014, 02:22:17 PM how can it know which address I generated?
Maybe because with that seed, every generated address is the subsequential? like 1xxxxxxxa; 1xxxxxxxxb and so on? I ask because I'm going to store some savings, and I'm scared that in a disaster event I'm going to lose everything... :-\ Title: Re: Electrum need backup?

There's some sort of a one-way algorithm to work it out, but I have no idea how. Title: Re: Electrum need backup?

I ask because I'm going to store some savings, and I'm scared that in a disaster event I'm going to lose everything... :-\ You won't lose everything. As long as you have those 12 words. Using my 12 words I could calculate the first 100 addresses (along with their WIF private keys) of my wallet for you in about 1 minute using commands in a Python console WITHOUT even touching Electrum OR the internet. It's all just math. 1 + 5 is always 6 Your 12 words will always generate the same addresses in the same order. Title: Re: Electrum need backup? Post by: Abdussamad on August 31, 2014, 03:46:35 PM You should backup the wallet file as well because it contains labels for transactions and addresses. These are not restored from seed. An alternative approach is to use the label sync plugin. Activate that in tools > plugins and follow on-screen instructions.
That's right. Even if all Electrum servers in the world go down! I dunno if that was supposed to be ironic, but you can still set up your own Electrum server if none are available. I don't think he was being sarcastic. He knows what he's talking about: https://bitcointalk.org/index.php?topic=73651.0 Title: Re: Electrum need backup?

I'm new with electrum so this may be a stupid question but: if I have received money from more than 100 addresses, does the seed changes or it is always the same? Title: Re: Electrum need backup?

The seed never changes unless you generate a new wallet. All addresses generated by Electrum can be recovered from the Seed. Imported addresses cannot be recovered. |
