Title: Enable HD wallet Post by: MadGamer on October 29, 2016, 02:34:04 PM I tried two options and I can't seem to get them working , the first is giving me back Method not found (code -32601) when I use "usehd" in the debug window and as for the second I can't find the Bitcoin.conf , I searched and I found that It should be in the AppData but I can't find anything there and It doesn't get auto generated either. (bitcoin-qt 0.13.1)
Title: Re: Enable HD wallet Post by: achow101 on October 29, 2016, 02:57:34 PM New wallets are HD by default. You cannot convert a non-HD wallet to an HD wallet.
You have to create the bitcoin.conf file by yourself. It isn't automatically generated. Title: Re: Enable HD wallet Post by: MadGamer on October 29, 2016, 03:29:09 PM New wallets are HD by default.

It isn't automatically generated. are you sure man ? then how come each time I got to the receiving addresses in the menu , I find the same addresses and I can create new ones myself , aren't HD wallets supposed to create a new address for you each time you want to receive ?

The "Receiving addresses" window that is found under the "File" menu is just a list of the addresses that you have requested so far. You won't get a new one until you request it. Title: Re: Enable HD wallet Post by: MadGamer on October 30, 2016, 07:53:37 AM

Understood (It's working fine) , and do I need to make backups as usual or all addresses are derived from one private key only ?

You only need to make a single backup (since they are derived from one master key) and you should be fine, unless you:1) Encrypt the wallet. 2) Change the passphrase. In these cases, you need to back up again.

In these cases, you need to back up again. Assuming we talk about the new HD feature and please keep in mind that I am not updated on the recent developments regarding that wallet version at all... This does not seem correct to me. The original seed should not be altered when the password to protect it is changed. Thus any initial backup, be it with or without password should allow a user to restore the wallet, regardless of later password changes. Did I miss something here? Is a new seed generated when the wallet is encrypted for the first time? Similar to what used to happen with the non-hd wallets where old unused private keys would be discarded before an initial encryption.

This is something that I've read in the 0.13.0 release notes, and have looked it up one more time after reading your post. This is what I've found:Quote If you create a new wallet with 0.13.0 (or above) and you change from the default unencrypted wallet to an encrypted wallet, a new HD wallet will be generated for you. You will still have access to any bitcoins sent to the unencrypted wallet, but you will need to backup the wallet again. https://bitcoincore.org/en/2016/08/23/release-0.13.0/This should be mentioned as well (I forgot to do so): Quote Importantly, if you manually import any private keys to your wallet, they cannot be recovered using any backups made prior to the import, so you will need to make a new wallet backup and use that.

I see, so its very similar to the non-HD wallets, where they dump the unused private keys. They cant do that with a HD one, so they dump the seed for a new one and import the used keys from the old seed. It should not happen when changing the password though.

Is master key = private key ? after generating some addresses , I went to the receiving in the menu (where all generated addresses are located) , I took some of them and used dumpprivkey , result shows private keys aren't the same ?

The addresses in a HD wallet are derived from a master key, however this does not mean that addresses have the same private key (this would not make sense). This is what makes it possible for a single backup to be used regardless of how many addresses you generate (which is not the case with a SD wallet). You should read up more about HD wallets.Title: Re: Enable HD wallet Post by: Dabs on November 01, 2016, 04:58:08 PM So I create a new wallet, and then encrypt it, and then dump it.

I'd like to create a HD watch-only wallet. That's a wallet dump from Bitcoin Core—there is no associated master public key. Core uses an entirely hardened BIP-32 path, which makes it impossible to create a master public key or an HD watch-only wallet. (edit: at least at the moment, there does seem to be a desire to do so eventually) |
