I just downloaded the 2.5.4 version and it is the same story as the latest version... I type my words but I can't click next...
Are you 100% sure you are typing the seed correctly? There is a checksum to detect typos. A single typo in the seed will prevent the "next" button from lighting up.

BTW, older versions of Electrum did not have the checksum, so if you type the seed wrong it will seem to work, but the addresses will be all wrong and you won't see your history/balances. That is why they added the checksum in newer versions.

I could try a brute force attack on the seed to look for a typo if Pappiony wants. Would require the seed, an address that belongs to the seed and an address where I should send the coins to if it was a success.

-snip-
It'd take ~ 24hours to get to the dreaded 50%, then it's something like another 24 hours to get to 75%, another 24 hours to 80% and so on.  Not sure why it does that.
24 hours is the time required for 50% chance to hit it. If you stop and restart your search at any possible time, it is still 24 hours for 50%. If you don't find it the first 24 hours, it is still 24 hours for 50% chance, but calculating from the start of your search, you have a 75% chance to find it in 2 days. You can be lucky or unlucky to find it.

I would say you are always lucky as you can never reach 100% anyway. There is no progress towards the goal, similar to mining bitcoin. It could take forever to find an address starting with 1btc its just not likely. I had simple addresses go to 98% (vanitygen does not show higher percentages) and even some more difficult ones.
2223  Economy / Services / Re: Bitcoin Vanity Addresses! on: March 20, 2016, 11:52:38 AM

Yeah, its the wording vanitygen uses. I usually use different words when making offers (exact case and any case). If the entry in the table is Y I used the -i flag. I prefer to go for quicker 6-18 hours (50% chance) addresses. I can direct the ones I deem too long for me to you if you want. IIRC you use 2 GPUs at a total of ~50Mkeys/s, right?

The first three examples are all the same - but the price you're suggesting are different.

They have a different difficulty, try it. The length is not the only factor. Different symbols have a different bit pattern that can be more or less difficult.
2224  Bitcoin / Electrum / Re: Electrum wallet on: March 20, 2016, 11:47:30 AM
I deleted everything, and downloaded the new version, but then I am back at where I started, that I can't click next.
I will try the other methode again, hope it works..

If you can get any version to work, you could export the private keys. That would give you more options as they are not limited to be used with electrum.
2225  Bitcoin / Electrum / Re: Electrum wallet on: March 20, 2016, 11:45:02 AM
Yeah I am sure. I did have a Multibit HD so maybe thats where the datestamp is from. I tried downloading the old version and I connected my wallet, but I can't upgrade to the current version? I tried downloading it from the site but it doens't work?

Any errors or just the same not accepting the seed? Can you get it to work with the old version?
2226  Economy / Services / Re: Bitcoin Vanity Addresses! on: March 20, 2016, 11:43:04 AM
I've only just come across this thread - are you looking for people to mine vanity wallets, or are you offering to do them just on your own?

I offer them on my own, but I have no problem if others adopt the model. My main cost factor is electricity and some other estimates I made to balance out the variance.

You should also take a look at this[1] post as most of the address have already been calculated and delivered.

Hi - I couldn't follow that post the first time around, so I've been working my way back through the last four pages.  I don't want to undercut you at all, so I'd go with what you are charging.  I'm more interested in this side of using my GPU's than for mining.

I think I'm interpreting your "case insensitive" back to front which is why the examples aren't making much sense.

I also don't mind setting and leaving run for a week or two.

shorena can I ask you how much it would cost me an address starting with 1SmartIphone exact case and case insensitive
I can answer that Smiley Exact case is not possible, an upper case i is not allowed. 1SmartiPhone would take about a million years. Case insensitive thousands of years. Anything above 8 digits is virtually impossible at the moment.

It's not lower "L" but it is uppercase of "i", I know it would cost a lot but just wondering how much would it cost, will wait for shorena.

Edit:
The shortest maybe would be only 1Smart

1Smart is easy to find. If the case is not important a donation would do. If you want exact case (1Smart) it would cost 0.0002 btc.

Ok shorena i will let you know shortly and will think about an alternative of my nickname(didn't know that "I" is not allowed), good luck with your sales.

Sure, just reply here or send me a PM. The possible symbols can be found here -> https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart

Hello,
I have an Electrum wallet on my laptop. I lost that charger so I won't be able to get in it for a month or so.
So I have a hire laptop from my school. I want to transfer the wallet with the long code I wrote down, but I can't click next when I typed them all. I also noticed that I only have 12 words... Am I screwed? I do have a date stamp.

Kind regarts,
Papi

Are you sure its electrum and not multibit HD?

"I" is not a valid character, if I replace it with a one (1) or a lower chase "i", the exact case would take ~45,000 years for a 50% chance.
Any case would only take ~900 years for a 50% chance.

If you can reduce it by 3-4 symbols I think I could make you one though.

Hi.
I don't know anything about computers and like me i suppose there is a lot of people. I'm missing one letter or a capital or some space in my passphrase. i all ready look in a lot of post and conversation, the answer but didn't understand anything. So if there is any body who wants to help solve this problem step by step for a retard like me i will create a blog or page with a video and the instructions given for all the newbies who are in the same problem like me.

help us as a community!!!
Please  Grin

#1 which wallet software/service do you use?
#2 If its on of the wallets listed under features here[1] I might be able to help you. I would need the wallet file, your best guess at the password (and what is missing where) and a new address from a new wallet where to send the coins to. Your old addresses should be considered compromised afterwards and no longer used.
#3 If you dont trust me, contact dave[2] and be careful about people approaching you via PM.

I wonder if you guys are just using different versions of the software.  Perhaps the filtering was added recently?


I'm using oclvanitygen64 and there doesn't appear to be a

Code:
-r

switch.

Yep, the GPU version cant do regex. Not sure why. Try

Code:
vanitygen64 -r test

I just reread the last couple of pages - I didn't know about this feature - I'd use it for middle or especially end of addresses, but the GPU cards can kept doing the front prefix.

If I have the "1" eg "1name" will the -r look just at the front?

Nope.

Code:
>vanitygen64.exe -r -k 1name
Pattern: 1name
Address: 1CKNZnaZa2p42woa11name5Deo8WSMnUXa
Privkey: 5K7hoViAWPeqcupUFM4PyyNvxQQKaiLfNcTcqxt63wWFe69ai3M
2234  Bitcoin / Bitcoin Technical Support / Re: Very Old Wallet - will it update flawlessly? on: March 18, 2016, 01:29:15 PM
Hey there.

In a couple hours i will receive back a laptop from the police that was seized in 2011. The computer contains an old bitcoin instance, if i remember correctly it should be around version 0.28, just short of 180k blocks. The wallet on said installation should contain several hundred bitcoin, so obviously before doing anything I'm gonna back the whole thing up.

Smart.

My question is -

A) the computer in question runs windows xp and a debian etch or lenny... Will a current bitcoin-qt run on windows xp?

Why bother? Just take the wallet.dat and sync with a modern machine, it will be faster anyway.

B) if i just upgrade the bitcoint client(i know there was some break in wallet compatibility and probably more than one libdb upgrade in between, which normally should have just transitioned)… will it convert the wallet to current standards and be able to use it?

AFAIK, yes.

C) if not, is the old pywallet still around and compatible allowing me to just dump the private keys?

-> https://github.com/jackjack-jj/pywallet

D) if none of the above, what should i do?

Ps: i know for certain that the wallet isnt encrypted - the feature was too new for me back then to be used, besides the root partition is crypted(and i still have keys)

You sure the coins are still no there? 5 years in the hands of someone else without encryption...

Hi guys especially to our seniors.

I just want to ask if there's a way to remove your negative trust once it is pinned on you?.

I just noticed in one of my accounts a warning from my other posts.

Thank you for your clarifications.

#1 talk the person that left the trust rating
#2 dont try to buy trust[1]

If you already announce it's your second account, why not just create the account using your own IP address? As far as I understand you can use it through TOR after you have created it from your own IP.
Your privacy is gone already when you started this topic, so why not just create another account.

BTW, I didn't know about the evil points. Learn something new every day!
Well, nope, I want everyone to know that I am MaryJane-Watson but nothing else.
I just want to keep anonymous and I don't want anyone to know where I am or something else.
Well, hiding my IP is no crime I guess.

Another point: When I first signed up, I did so with Tor (no real IP)

Hence the suggestion to try again. Not all exit nodes are this expensive.
Why should OP have to "try again"?

No one is forcing OP, it was just a suggestion.

He made a account already. What if this username has some kind of significance? If OP can just "keep trying" until he does not need to pay a fee using TOR, then why not just let him use the username that he made the first time?

Sure, easy.

#1 pay (is apparently no choice for OP)
#2 hope someone vouches for you to get whitelisted. (does not seem to happen either)

sorry my english is not so good Smiley Smiley Smiley

Really? You advertise a ponzi with your alt. I personally remove these ratings once you stop advertising the ponzi and tell me you did. Now, that you are trying to buy trust Im not so sure I will remove the rating.
2239  Other / Beginners & Help / Re: Brute forcing question. on: March 18, 2016, 07:27:30 AM
Yes, it would be easier.

If they knew how many bits of entropy your password was, they could rule out passwords not under that entropy strength, and narrow down their search for your password.

No it does not, because if the attacker does not know the set of symbols used, knowing the entropy does not help them. I can tell you have an 32 bit (which is weak) password. You are no closer to knowing my password which could be made off words, numbers, latin alphanumeric symbols, special characters, cyrillic symbols, utf-8 or any mix of them. There is a theoretical advantage that you only need to test a subset of all possible passwords for each set of symbols, but you might still need to test a possible infinity number of symbol sets.

Also in order to brute force something you need the file. So if the question is whether you can tell someone your password strength, you can. Keep in mind though that the entropy depends on the way you generate a password. Selecting a random word from a list of 8 words, only has 3 bits of entropy no matter how long and complex the words are. If your password is not generated randomly it might be impossible to determine its entropy.
