Bitcoin Core version 0.13.0 Released

[yayayo]

Finally! The 0.13.0 release was long awaited. The number of improvements is really large. Despite the difficult situation caused by the frequent attacks by the big block ideologists, Core developers did a great job in improving the reference client.

With segregated witness that will be activated soon, Bitcoin is on a good way for further growth without putting decentralization at risk. With segwit, moderate blocksize increases and lightning networks, Bitcoin will scale efficiently for mainstream adoption.

ya.ya.yo!

I like how they depreciated the Windows XP and removed the internal miner. The latter was just sitting there for no valid reason.

There will be minor changes regarding Segwit between 0.13.0 and 0.13.1. In the meantime, it's time to check out the results of compact blocks.
Does anyone know whether the Linux repository has already been updated? I don't want to shut down the client just to verify that it isn't one more time (as I've done this yesterday).

Well I guess I am still conservative... I will stick to 0.12 for the time being until all the security issues has been solved...

There are no security issues with the version 0.13.0 itself. What are you talking about exactly? If you're talking about the binary warning, that's nothing special. You should have been verifying the downloads from day 1. There's a good guide to verify the files.

[BitHodler]

I have verified the hash and everything is what it should be. Honestly speaking, this is the first time ever I check the client software before installing it.

It was quite naive from me to assume that when I download the client from bitcoin.org that everything would be 100% safe. Now I know better of course.

Plot twist: the warning was just for everyone to start checking the files they download

I'm obviously joking.

That's how we move forward. Enough with supporting XP (generally speaking).

"Backups of HD wallets, regardless of when they have been created, can
therefore be used to re-generate all possible private keys, even the
ones which haven't already been generated during the time of thebackup."

if i understood correctly this mean that the 100 pool address is olved, when you restore a backup after you have used all the privatekey previously generated, and added a new one? i can do this now without worrying about losing my coin?

Yes. Only thing you need to worry about is backing up every time you encrypt the wallet or change the password.

Hi how does this work then? Is this the right thing to do?


1) Backup wallet.dat from your 0.12.1 folder
2) Delete wallet.dat from your 0.12.1 folder
3) Install 0.13.0 and open it so it generates a new wallet.dat file (this is now the HD wallet file I guess?)
4) Sync the wallet, once it's synced close the client.
5) Now you have a synced 0.13.0 but you need to boot 0.12.1 wallet again to send to the empty new 0.13.0 wallet...

how do I continue from here? I need to have 2 different versions of Bitcoin installed at the same time..

1) open your phone
2) do a transaction of all bitcoins in your phone (bitcoin android wallet)
3) change to bitcoin core and create HD wallet
4) do a transaction from phone to bitcoin core HD wallet

consolidate bitcoins.
use the network.
pay the fees.

Too risky to use phone to move big funds over there, also, to stay anonymous one would need to send several different transactions which means more fees, this is so annoying.

Yes. Only thing you need to worry about is backing up every time you encrypt the wallet or change the password.

So this means you can use the old wallet and don't need to send coins to the new wallet?

Correct, it's not mandatory to switch to an HD wallet.

Correct, it's not mandatory to switch to an HD wallet.

But if you do want to use an HD wallet, you will need to send coins to a newly created HD wallet and you can't use the old wallet.

so now to use this i need to re-index again the blockchain and remove pruning, this is really a pain in the ass for each new update..can this be fixed in the future, or this is a lost cause?

No you don't. Just install the new version and start it with pruning.

  ... stop using phone to download stupid game ?
and IF you have so big fund, why you don't have PC and phone dedicated to Bitcoin ?

Bitcoin, it's a bank, your bank in your pocket.

v0.13.0 is really really fast to recreate from zero, the local blockchain ... It's perfect !
Less than 36 hours in Core 2 Duo E7500 (2,93GHz) ... it's perfect for slow notebook !

[B1tUnl0ck3r]

Work of art! Congratulations guys!!! it's splendid.

for info I raised my mempool to 600mb and right now it's a 513.30mb still on 0.12.1.

I will update now.

Anyone figure out a way to create a new HD wallet, and import a "watch-only" HD wallet? My purpose is so that the watch only wallet is on a live server, while the HD wallet with the private keys are on an air gapped computer or on a more secure one anyway.

I'm curious too, and wondering if this is even a possibility...

[Meuh6879]

You can't import a seed right now on this version.
That's why i use the command line usehd=0 on bitcoin.conf for now.

for me Bitcoin Core is the base of Bitcoin Network, it must export AND import private key (or seed).
