People keep messaging me saying they need my wallet.dat to fix this, well that's not going to happen.. im not dumb.

Good!  Don't give anyone your wallet.    Glad you didn't send it to them!

Are you sure that this is the correct wallet.dat?  And you have backups?

This thread was on 2013 so I didn't have seen the update did he actually recover his money or something.
Because that is just a lot of money that you have lost. At least you should have got 500K back.
So anybody any update about this thread?

He didn't get it back.  Cyprus gave a "haircut" (stole) to a lot of people's money.

I believe he moved his business to somewhere in the Caribbean. 
2143  Bitcoin / Bitcoin Technical Support / Re: ar76 on: December 19, 2015, 09:26:01 PM
yes I did it. But for example today was to synchronize the portfolio and the power failed and had to start over three years ago that is the beginning and it takes me months to be able to synchronize the wallet

A UPS might help here if power failures are causing database corruption. 

Likewise, as others have mentioned, more powerful hardware will help it to synchronize the blocks faster.
2144  Bitcoin / Development & Technical Discussion / Re: Why keep a history of transactions? on: December 18, 2015, 08:52:19 PM
There are transactions with inputs (outputs that are being spent) and newly created outputs.

No balances.  No addresses.  No bitcoins.

Just transactions made up of inputs and outputs.
Inputs and outputs ARE balances/bitcoins.

No they aren't.  They are abstractions of inputs and outputs which is what Danny is pointing out. 

If you are talking about "balances" it is important to understand how bitcoin works and does not track balances.  This is an important point to be clear about since it does not reflect the underlying design.

What is the origin and meaning of the name "Decred"? How is it pronounced?

tacotime came up with it while brainstorming with c0. If I remember correctly, it was on the topic of "decentralized credits". It's kind of taken on a meaning of its own now. It seems that most people who see it think it's pronounced "dee-cred".

In terms of the name, made up words are always nice since you don't have to translate them (an idea that goes back at least to Kodak if not earlier).

Even back to Castoria from the mid 1800s  (see e.g. https://en.wikipedia.org/wiki/Fletcher%27s_Laxative)

I sent my bitcoins to BTC-E, however there is no confirmations after 48 hours, nor is there any log on blockchain of the transaction using the ID?

How do i get my bitcoins back?

If there is no TXID, your bitcoins haven't moved so no need to "get them back."

  Try quitting Bitcoin core and relaunching with the -zapwallet parameter.

Then resend with the recommended fees.

Edit:  the old thread had more info.  Backup wallet.dat.  So, run the current version.  If it is behind, let it resync. Try re-sending once it does.

2147  Bitcoin / Development & Technical Discussion / Re: Blocksize needs to be increased now. on: December 17, 2015, 07:23:18 PM
Dude, the 8 MB limit is not each and ever block. If the cap is 8mb, and the current block size is 0.5 mb , then 0.5 mb blocks will circulate. The 8mb block is only the cap limit, not the default size.

There's no problem with 8MB blocks but do you have a way to deal with stress testers? Do you know how make their tests more expensive? Higher dust limit and Higher fees?

Maybe we should go to 2MB first which is a 100% increase.


Stress testers?  Disable 0 bitcoin fees. If they want to test, pay for it.

A stress test is the same as regular transaction. Pay and then they can send as many TX they want.

0 bitcoin fee should be disabled at protocol level. Minimum should be at least 1000 satoshi.

There is a minimum, not at protocol level but at the node level which is set by default to 0.00005. Any fee under that is not relayed by the node.

Also, the stress tests do not send transactions with 0 fees. They always send with enough fees.

This is an important point - they are paying fees for the majority of the stress tests.  Eventually they will run out of bitcoins to use for the stress test and will have to buy on the open market.   The so-called stress tests are not costless so can't continue indefinitely without driving up the fiat value of bitcoin.

2148  Bitcoin / Bitcoin Technical Support / Re: error reading wallet.dat on: December 15, 2015, 05:52:04 PM
You can always try it.  BUT:
1. Make sure you have extra backups of both.
2. Don't actually REPLACE the old wallet.dat, just rename it to something else and use a COPY of the backup.  This way you will have the wallet.dat that is given you a problem now and a number of backups.
2149  Bitcoin / Development & Technical Discussion / Re: Soft Fork to Increase the 21M Limit? on: December 15, 2015, 05:49:34 PM
Why the hell would we want to increase the 21M limit?

1 bitcoin is dividable into god knows how many decimals. Scarcity of coins is key otherwise the price would plummet. 

Any change that would increase the 21M limit would create an alt-coin, that is not bitcoin.  If the question is something akin to namecoin running in parallel to bitcoin, then I think at best you'd get a similar valuation to namecoin, probably less since at least NC has an additional function.

These types of arguments were made before the last halving about miners shutting down etc.  Sure, there may be some miners who shut down really non-profitable rigs (perhaps old Avalons for example if they are still running), but if they are covering power costs alone, they'll keep them running.  The sunk cost from the purchase price is just that, a sunk cost.  In November 2012, difficulty dropped slightly after the halving (the first and second readjustments were down slightly around 1-2% and 9-10% iirc) but within about 8-10 weeks was up.  Given the number of new ASICs that will be coming online in the next 8 months until the halving, I would expect something similar.  There may be a slight drop in July/August, then difficulty will recover.  Time will tell.

Segregated witness

Is there a formal paper regarding "segregated witness"? Sounds like something new. If a new crypto construction is going to be implemented we better make sure it is thoroughly tested and reviewed because we are betting the present and future value of all our bitcoins in that there will be no serious holes.


Some info is here:

reason i want to is that one is for me the other for my friend

You'd have to set different ports for each one then.  One p2pool is on 9332.  You can set it to a different port for #2. 

You can't both use the same pool?

2153  Alternate cryptocurrencies / Mining (Altcoins) / Re: p2pool running multiple *coind's - same error - Twisted? on: December 13, 2015, 05:48:16 PM
is it possbile to run 2 p2pool/bitcoind on the same machine ?

i've tried a bit but no luck


p2pool: Error binding to worker port: Couldn't listen on any:9332: [Errno 98] Address already in use.

Yes it is possible to run both p2pool an bitcoind on the same machine.  If you are asking about running two of each, then that too could be done with some configuration of ports, but wouldn't really make much sense to do so.

You can use netstat or another tool to see what is bound to that port.  e.g. something like:
Code:
netstat -tulpn

You might have some more luck asking in here too:

Well , aren't the developers planning to do a debate about this on December ? or it's already done and decided ? If not .. hopefully they will agree on something this time .

There was a workshop last weekend on this topic but I'm not sure if there was much progress. At least I haven't been able to find any indication that a consensus was found but I really hope I'm wrong.

Dude they presented signature witness and it was pretty huge, look it up it's a pretty cool feature that will give us time to scale it a bit while LN cooks up. I think there is nothing to fear for now. I have no idea when sigwit will be operative tho, but I think it should be rather soon, maybe in 0.12.

oh  Shocked thanx i'll fix it

If you look at the link Newar sent, I think it has a reasonable PRNG in there - I didn't look to see though.

This is a good way to learn about bitcoin, for sure.  ;-)
2156  Bitcoin / Development & Technical Discussion / Re: PyBTC Bitcoin Address's Generator (offline) and More on: December 10, 2015, 06:13:49 PM
also you can use your private key  Wink so don't worry

You should not rely on this code if the part I am looking it is accurate.
You are picking a number between 0 and 0xfffff (1,048,575)
Code:
rand = random.randint(0x00000,0xfffff)

That is not large enough and could be searched in seconds - meaning your coins will be stolen.

You should fix the code.
2157  Bitcoin / Development & Technical Discussion / Re: PyBTC Bitcoin Address's Generator (offline) and More on: December 10, 2015, 05:13:15 PM
One concern I'd have is with the PRNG that is in use.  

:-)
e.g.
Code:
def rankey():
rand = random.randint(0x00000,0xfffff)
key = sha256(str(rand).encode('hex')).hexdigest()
return key

Maybe add:
System memory: 1GB, 4GB etc
Number of connections to bitcoin core: e.g. 8 or less.  More than 8.
For the Operating system, perhaps O.S. AND version number:
Have you made a backup copy of your wallet.dat file: yes/no

Do you have a more verbose error log then?  :-)

Me?  No.  I'm not the OP.  That's the same thing I was asking of the OP.  (Maybe you were just emphasizing?)

That was to OP.  I had just cut out all the replies between the two of us.  :-)
