Bitcoin Core 0.9.3 has been released

[OmegaStarScream]

Thanks for sharing & Great work Developpers !
Could anyone please tell me what to do to save Private keys ? I don't see it in the GUI (Windows) , Console command maybe ? thanks

Are you trying to backup your private keys? If so, you should just backup the whole wallet by clicking File -> Backup Wallet

I should only take this backup once at lifetime ? or Take it like one a day , or once a week ?

Roughly every 50 tx.

Alright , thanks for the answer dude , but I barely make that amount of transactions anyway

Hmm. Perhaps I need to try again.

How do each of you feel about the fact that it is impossible to verify that Bitcoin 0.9.3 is an official build, and therefore unlikely to have a backdoor that allows some nefarious party to steal your bitcoins?

Or, if there is a way to verify this, how does one do so?

Not sure what you mean. There's file signature hashes published at https://bitcoin.org/en/download . That file is signed with Wladimirs key.

Near as I can tell, 'Wladimir's key' is unverifiable as being Wladimir's key. Perhaps I am doing it wrong, but this is what I see:

Code:

You have to sign his key and add it to your trust database.

Sign who's key? That's the question. How do I know this is Wladimir's key?

Thanks.

I hate to be recursive, but how do I know that is Wladimir's key? Is there a more robust mechanism than going to a (hackable) webpage, and downloading a (hackable) *.asc file -- which itself exists upon said webpage with no explanation other than it appears in the same row of a table that also includes Wladimir's name and email? It seems to me that we'd have a better system for something upon which billions of USD of value depends.

[Parazyd]

If you're that paranoid, email one of the core devs or PM them on the forums.

[Newar]

The key can also be found on github, so they would need to hack that too.

Emailing won't help either as you still can't be sure. (If you're that paranoid...)

Bitcoin Core is a bitcoin wallet, first created by satoshi.

Before trying to get bitcoin, I think you should first learn about the basics about wallet and transaction. The bitcoin wiki should be helpful to you.

just downloaded it!

The linked article is very interesting - thanks. However, it merely raises more questions.

- the AT&T Path Server is evidently offline, with its return being in doubt. Is there an alternative?

- why is there not already a web of trust relationship for Wladimir's key? Or if such exists, how do I learn about that?

gpg does it for you. Or rather you build your own web of trust using it. Like Parazyd said you sign keys of people (which ideally you have met in person and checked their key fingerprint and ID). Others you can assign "trust". Depending on steps outlined in [1], if some of those people are in Wladimir's web of trust too (one way or the other) then your gpg will trust his key too. That is at least my understanding.

As for the graphical representation it's nice, but not necessary as gpg will do it for you anyway.

There is a graphical implementation for #bitcoin-otc [2] for example, but of course only for people who submitted their keys there. I guess AT&T stopped it because it used too many resources. But again, graphics are nice, but not necessary.

Having to use old wallet as 0.9.3 continues to crash my system. Tried to wipe everything clean install. Gets to about 95% on block chain downloaded and indexed and shortly after crashes and when re open it then says re building blockchain. Yet on older version no problems are at be.

What could the cause of this be?

same for my WinXP SP3 ... i must stay at 0.9.1 to have no crash at all with continious running time.
0.9.2 and early crash after 19-28 hours ... with no explications (no errors, process is killed by itself).

Nice to see an update and looking at the release notes seems that this is going to make things a lot better in the future and when theirs a final release of it made public and testing done. Maybe this will fix a lot of the problems that the past releases of the wallet has been caused due to the sync problems and liability of the wallet. I will wait till theirs a full public release and not beta to test and then upgrade and see how it works out. Maybe this release will actually fix the syn and crash problems I had in the 0.9.3 release as can not seem to use it.

[Amph]

what about adding a conversion rate directly to the client?
