[ANNOUNCE] Electrum - Lightweight Bitcoin Client

[OmegaStarScream]

Is "CoinShuffle" being implemented into the client?

Where you got this from ? I searched both repository and documentations and couldn't find anything about it. I guess you are mixing Electrum with Mycelium : https://twitter.com/myceliumcom/status/765214573616037888 (It's not implemented yet but they are working on it)

I have bought a Trezor and want it to connect to my Electrum wallet, but i can only find tutorials with Trezor and creating a new wallet. So i have a few questions:

- Can i use Trezor with excisting Electrum wallet?

Better not.  The Electrum wallet on your computer is a file that contains private keys that may have been compromised by the simple fact that they were inside a file sitting on your computer...   The private keys in your Trezor will never see the light of day.  You invested $100 to safeguard your bitcoins?  Start on the right foot - create new private keys.  To do so, initialize your Trezor with mytrezor.com (write your seed words !). Now that you have created your private keys inside your Trezor, let Electrum know of your corresponding public keys: Start Electrum, and create a new wallet (File --> New/Restore --> give a name to your new Electrum/Trezor "public" wallet --> Create New Wallet & Hardware Wallet -->  Initialize a new Wallet & Trezor).  Electrum will create a new Trezor wallet on your computer, but it will contain only public information, like public keys and transaction information - no private keys whatsoever - the private keys always remain within the Trezor H/W.

A transfer of your old Electrum wallet BTC to the new Trezor addresses, using the bitcoin network, is the best "transfer" solution.

- If not, can i create a new wallet with Electrum and Trezor and that it creates 2000 new btc addresses again? If so, how can i do that?

You failed to mention why you would need 2000 addresses - You obviously have a special requirement that you didn't explain.  Electrum/Trezor will function the same way that Electrum alone functioned, and it will create new keys as required (beyond the initial 20 addresses), once you used them up.     If you really want 2000 new BTC addresses from the start, you can increase the gap limit from default 20 addresses to 2000.  But if you do - be careful about recovering from seed - make sure you write next to your seed words that you did that.  

So if you really really have to create 2000 addresses from the start - do this in the Electrum console tab:

wallet.change_gap_limit(2000)

... and then check the long list of addresses in the Address tab.   But again, if you recover your wallet from seed and don't increase the gap limit again to 2000, you will think that you are missing some bitcoins  - don't complain!

The private key of electrum is in form of file right? But if we set password it will be encrypted right?
So is it really safe using electrum? or should I remove my electrum completely so I do not have to change my private key

There are bitcoin stealing malware that keylog your passphrase and steal your wallet.dat. Using a password is important, but the safest way to use Electrum is to get your private keys offline. You can do cold storage using two computers, there are directions at the Electrum website. Of course you have to keep one computer offline forever if you go that route. That is why hardware wallets like Trezor that integrate well with Electrum have become popular.

Hi developers,

There is an android version of Electrum wallet on Playstore. Can I confirm this is by your team too:

Hi developers,

There is an android version of Electrum wallet on Playstore. Can I confirm this is by your team too:

It's their app but almost no one use it (to confirm next time , visit their official website https://electrum.org/#download and confirm the signature). Instead , you may want to take a look at Mycelium which is probably the most used Android wallet out there (and more awesome features are coming soon as well) . Electrum is more used for Desktop instead , android version isn't that good.

[BitcoinNewsMagazine]

Mycelium is a must if you want to use a hardware wallet with your Android phone, but Breadwallet is worth taking a look at also.

Yes, this is Electrum for Android.
It is running the same code as the desktop version, only the GUI is different.

Hi Thomas. Thanks. i was initially worried but your assurance matters a lot. I will download to use it as a form of cold wallet with spare phone.

Does that mean it supports trezor?

That should be the case according to the SatoshiLabs documentations : https://doc.satoshilabs.com/trezor-apps/electrum.html On the platform field It clearly says "Windows, Linux, OSX, Android".

the current APK does not support hardware wallets. we are working on this.

Old versions of Windows might need to install the KB2999226 Windows update.

So electrum has been out since late 2011? 



Was electrum and bitcoin core the main wallets ppl used back then in 2011 and 2012 to store their btc?  I assume it was bitcoin core... but you had to download entire blockchain and sync... then ppl went to electrum afterwards?



Was there any hacks or issues like with electrum back then like it had been not long ago with all the phishing?   Or did all this happen right when crypto got big? 

[HCP]

Like most of the big hacks... it's mostly due to the significant increase in value of BTC (and other cryptocurrencies)... It has become very profitable to invest time/money in finding and exploiting vulnerabilities in crypto based systems.

When Bitcoin was worth 10c, no one cared... now that it's worth $10,000 the value proposition is quite substantial

Which version are you using? Download and install the latest version from Electrum.org, that should solve it If you're using an old client.
