1  Bitcoin / Wallet software / Re: Got a pywallet dump, now what? Please! on: January 03, 2016, 09:49:04 PM
THANKS ALL!

I seem to have successfully sweeped over to electum, just waiting for tx confirm now.

This might be of help to you if you plan on using Electrum then: https://en.bitcoin.it/wiki/Transferring_coins_from_Bitcoin-Qt_to_Electrum

Thanks, I think I've seen that already and it left me with more questions than answers!
e.g. "Click Help -> Debug. Click the Console tab. Use the dumpprivkey command to get the private key. Repeat for as many bitcoin addresses as have money in them. "
That might make sense to a seasoned pro, but not me! My first question was where do I get this mythical list of addresses from (accounting for change etc?)
I tried using listaddressgroups but I was convinced BTC was missing, presumably that only produces reliable output after a full sync?
This is exactly why I kept going round in circles on the how-to's, as I was unsure of being able to do that stuff with only a 70% synced bitcoin core, so started playing with pywallet.

However now I understand the pywallet dump a bit more (see below) I think I'm close to that giving me the same info.

The private keys you want to import cannot be the encrypted_privkey output. You must use dumpwallet with the passphrase to get the unencrypted private keys. Those keys should start with '5', 'K', or 'L'. If they don't, then something is wrong.

Wow, thank you for pointing that out! This is I think the EXACT void in my understanding, I didn't know it's content or format so I was hoping for a software solution that did, to make it real simple.
OK so if I compare pywallet dump with/without passphrase.

The wallet is encrypted but no passphrase is used
{
    "bestblock": <redacted>
    "ckey": [],
    "defaultkey": <an address I recognize>
    "keys": [
        {
            "addr": <an address I don't recognize>
            "compressed": true,
            "encrypted_privkey": <redacted>
            "pubkey": <redacted>
            "reserve": 1
--

With passphrase applied there are extra fields:
The wallet is encrypted and the passphrase is correct
{
    "bestblock": <redacted>
    "ckey": [],
    "defaultkey": <an address I recognize>
    "keys": [
        {
            "addr": <an address I don't recognize>,
            "compressed": true,
            "encrypted_privkey": <redacted>,
            "hexsec": <redacted>,
            "pubkey": <redacted>",
            "reserve": 1,
            "sec": "K---something <redacted>"
            "secret": <redacted>

---

Looking at the "sec" field of the various addresses, every single one starts with a K or an L.   Are these my mysterious (to me) private keys!?
I would never have known without your tip  Wink

It is a very good wallet and you can import your private keys there, although I recommend that you actually create a wallet with Electrum and then sweep your exported private keys.

Ok groovy.  Having done some manipulation on the pywallet dump (with password) to extract all references to the "sec": field I have what I think are 212 private keys.
Is there nothing else I need from the dump output?
So I install Electum, set a new wallet, tell it to Sweep those keys and I'm good to go?

Well it depends on what wallet you intend to import your private keys into. Have you made a choice of wallet yet?

Thank you, a very good question!  And to be honest, right now I'm not sure I care (famous words of desperation!).  Perhaps foolishly, having patiently tried bitcoin core over and over, I do feel quite desperate to free up my coins as there is something I'd like to buy.

I don't really have a long-term wallet choice yet.  Perhaps electrum.  But right now to get started, I just want anything that will give me access to my coins locked away in my encrypted wallet.dat, and worry about what to do with them once I've got that far.

That's why I thought I'd post here for some voices of experience.  I've been dipping in and out of documentation for the popular alternative clients and to be honest it's sending me slightly crazy.  I haven't seen any import processes described that I fully understand, some favour coin xfer not import, and really I'm looking for something idiot proof like copy your wallet.dat here, or paste your pywallet dump into this box etc.

So I'd really appreciate any advice along the lines of "well if you pick client X this is dead easy, just do Y and you'll have access to your coins".  Priority is ease of import/access.   Security I can think more about later? And if it all goes wrong and my coins are stolen, I'm not worse than I am now, with a wallet.dat that I haven't been able to do anything with for many months!


4  Bitcoin / Wallet software / Got a pywallet dump, now what? Please! on: January 03, 2016, 06:38:34 PM
Hi All
I have to move away from bitcoin core.  I don't actively participate anymore in mining etc, but got some wallet.dat backups I'd like to do something with.
I've been trying since the summer to get 11.x to sync, this sub isn't the place to go into that except it's crash crash crash, reindex, crash crash crash then no block source available.

So I have to move to a different thinner client.  Please understand I can't do this by transferring coin elsewhere, because I cannot get a full-node install to sync. So unless I'm mistaken, my only option is to export wallet.dat over to another solution.

I don't really understand how bitcoin works under the skin, private keys public keys etc, so talk to me like I'm 5 please.  But it seemed like getting a --dumpwallet out of pywallet was essential to help me move forward.  But I can't figure which clients will accept this.  With a lot of trial and error I have two outputs from pywallet, one with passphrase provided, one without. 

Question:  What difference does providing the passphrase to pywallet make in this context? The output looks largely identical, with all private keys of type encrypted_privkey in both copies.

Question:  When trying to import that into stuff, which copy should I use?

Question:  Now with --dumpwallet output, which alternative client can I use this output with please for a painless transition?

Essentially, I have the most precious thing - wallet.dat, and now a pywallet dump, I just don't know how to move either over to something else.

Many thanks Smiley
5  Bitcoin / Bitcoin Technical Support / Re: Help - bitcoinc ore 0.9.3.0 won't complete sync on: November 01, 2014, 10:14:35 PM
Used the blockchain torrent and now synced all the way down to 12 days and still moving.

Nonetheless this experience leaves me deeply concerned that that 0.9.3 win64bit is broken or the network is struggling to support full new blockchain sync downloads properly.  I expected to need to be patient, but when a sync hangs for 24 hours with no block source available, and refuses to budge after multiple client restarts, something can't be right...

6  Bitcoin / Bitcoin Technical Support / Re: Help - bitcoinc ore 0.9.3.0 won't complete sync on: November 01, 2014, 05:35:27 PM
Just to add it's been 70 minutes since last restart, it's not moved on a single block and still reports no block source available with 8 connections.
7  Bitcoin / Bitcoin Technical Support / Re: Help - bitcoinc ore 0.9.3.0 won't complete sync on: November 01, 2014, 04:40:27 PM
Hi,
Tried several restarts but it gets back to the block position where I left it and stalls
Needed to reboot for something anyway (made sure bitcoin shutdown clean first) so it's just had another start.
Back up to 8 peers connected, status currently "no block source available" and still stuck at block 297402

Specs are Win8.1 64bit, 16Gb RAM, over 130Gb free on the drive I installed the client to (E:\Bitcoin).
Thinking about it it's the first time I've tried Bitcoin in a non-default location.

8  Bitcoin / Bitcoin Technical Support / Help - bitcoinc ore 0.9.3.0 won't complete sync on: November 01, 2014, 02:01:07 PM
Hey all
I've moved my bitcoin client to another machine and at the same time used the opportunity to upgrade to v0.9.3.0-g40d2041-beta (64-bit)
Wasn't worried about redownloading the blockchain, got decent broadband speeds and never been a problem before.

My wallet backup is safe so started with a fresh install and intend to copy my wallet back over when it's synced.

But for the life in me I cannot get it to sync.
First attempt after 3 days hung at 14 weeks. Client status was "no block source available".
I saw in another thread to add a bunch of addnodes in the debug console, I added about 10.
Left it for a few hours, nothing changed, still stalled.
I tried launching the client with a -reindex, this time it stalled at 27 weeks (been stuck there for 24 hours). Status is still "Synchronizing with network" but it cannot get past block 297402.

I'm not very experienced with configuring the client or more advanced console commands and am at the limit of my know-how.  I'm not using VPN or TOR or anything weird.

Any tips and ideas would be really welcome!
9  Alternate cryptocurrencies / Altcoin Discussion / Re: The Largest $ Monetary TWEET in History Happened Yesterday with Cryptocurrency on: March 16, 2014, 05:04:22 PM
Please don't remove this to Meta or Alt-currency. This is not just about Dogecoin, but about CryptoCurrency in general.  This story demonstrates the sustainability and functionality of Cryptocurrency. It demonstrates a perfect example to the Bitcoin haters why cryptocurrency is the future of payments.

Yesterday someone sent approximately $14,000 via Twitter to Doges4Water, a fundraiser to build 2 wells in drought stricken Kenya.  That transfer cost the sender about $0.01 and occurred almost instantaneously because it was done with cryptocurrency.

I'm sure of a bunch of crypto coin will be really useful to the poor thirsty people of Kenya.  Can they pop to the shops to buy bottled water in doge?  Or pay for well construction workers? Or filtration systems?  What will the REAL cost of that transfer be after exchange fees, SEPA fees and currency conversion?
10  Bitcoin / Bitcoin Discussion / Re: The real price of bitcoin, less than an iphone app on: March 16, 2014, 04:48:22 PM
Facebook didn't pay so much for an app. Facebook paid so much for the users that are using it. The users and their data is the product.

^^ This.  FB paid $19b for 350million - 490million (depending on which source you read) user assets.  The app means nothing to them, I mean come on they already have facebook messenger right? FB must have the in-house development skills to clone WhatsApp in a week.  But for a business who's sole purpose is to profile people for advertising $$$, slurping all those extra contact lists and mobile phone books for "who knows who" is where the value was in that deal.  And given that Bitcoin, by design, protects user anonymity with no centralized userDB, the two things don't make a suitable comparison. They placed that value on WhatsApp in terms of something like $45 per user, not the app, code or service itself. IMHO.

Ever since Slush withdrew from offering support in this thread I felt it wise to leave the pool.
A private trouble ticket system is no replacement for public, transparent and open community discussion of problems that may affect many people.
Previously I left BTCMine when the operator went AWOL from the pool thread.

Personally I benchmark any pool on the support its operator offers through this forum.
Worth thinking about guys and gals.

13  Bitcoin / Bitcoin Discussion / Re: Don't get BFL'd by NFC Ring on: February 16, 2014, 08:00:39 PM
Various parts (actually most) of what tenthirtyone has posted is factually incorrect, I'm not going to nit-pick on this.  Should anyone wish for me to point out which parts are incorrect I can but I feel it doesn't add anything positive to the conversation.

Yes having reviewed your Kickstarter and the pastebin correspondance, I'm an "anyone" who is interested in understanding further why the majority of tenthirtyone's post is incorrect.  I suspect we will then see why you don't wish to nit-pick on this.

1) We wont have our staff talked to as if they aren't humans with feelings.
I think pissed off customers and investors happens in business.  The measure is how you respond to them.

2) We want our community to have a positive or constructively critical approach to the NFC Ring project/experience.
I don't see that stipulated on your kickstarter terms.

3) We want our community to at least attempt to read the documentation provided, we also provide video updates every other week.
That's great, but he just wanted a straight answer didn't he, even just a best guess or "no promises" estimate would have likely put his mind at rest.
Is that so difficult?

4) Kickstarter is not a store.
Indeed, but you also have a responsibility to do accurate shipping forecasts when setting up one.
You're now 5 months late and seem to think you have nothing to apologise for, just attack someone, using some real stretching reasons,  who dare take issue with this.

What happened here is that tenthirtyone wasn't(in our opinion) fit to be a backer of this project and his attitude wasn't apt for our community so we decided to part ways.  Communities sometimes require a certain level of moderation (as I'm sure the mods on this forum will understand), in this instance we decided to take action that was negative for tenthirtyone, this is the only time we have taken this action and this makes tenthirtyone an exceptional case.
That's one way of looking at it.  A slightly more accurate way to look at it might be that you couldn't handle being challenged so took your bat and ball home.

In no ways has he been BFL'd, he got a full refund and we politely parted ways.
Late delivery, or cancelling an order due to some challenging questions are entirely characteristics of BFL, I'm afraid.

Really really annoying.  Happens every time I want to login and make a quick post on a thread I'm following.  The worst bit is I then lose whatever I've just typed out, the message input doesn't get restored on a back button press, which I've noticed some forums to manage.   I do understand this is to protect the security of the forum from DOS etc, but this must be solvable surely.  Maybe the database needs two write flags a last_login_in flag and a last_post_flag in order to differentiate the two completely different actions.
