Help please.

Anyon
Hello,
I offer my services of gmail accounts creating.
You can send me a PM with the accounts that you want and the price, you have to pay me first.
e can create gmail account for free why should they pay you for it?How is account created by you is going to be differnt tham\n the one we create ourself?

 The difference is, he's going to know your password and have the ability to reset it with his own phone number/alternate e-mail even after you change it.

be prepared to wait while it scans the blockchain for transactions (could take a while).  There is a noscan option for that command but it's inadviseable.  I think you would type false after your label.
I didn't know the noscan-option exists. "Noscan" would be okay if you import the address before depositing to the address, or if you want to import several addresses and scan them all at once afterwards (rescan 86 GB can take longer than creating the address).

It would be great if this also works with a "pruned" Blockchain, so you can still import vanity addresses without downloading the entire blockchain again.

Any idea what the exact command would be? I've tried several options (noscan, norescan, rescan=0, rescan=false), but it instantly says "Rescan is disabled in pruned mode". I don't want to rescan, I just want to import the address.
Someone posted the same idea on Github 2 weeks ago. I guess it's not possible yet.

In a way importing vanity addresses is the same as importing from cold storage. It has been tested on Reddit. Conclusion: It should be possible to get the balance without downloading the full blockchain again, but it's not (yet?) implemented.

Edit: I'm confused: somehow it did add a watch only address, but it says it requires a rescan to show the balance. I haven't been able to import the private key though.
Now I get what you meant! I did "importaddress 1something rescan false". It imports the address without rescan, and "rescan" is the label of the address. So I should import it useing "importaddress 1something Something false" to give it a more useful label.

 You got it!  It takes no time at all this way but if you had coins in there, they might not show up until the next rescan.

Everyone on vacation this week?Huh  I'm heading out shortly for a few days.  Catch me on Slack, BBM (for those of you who have me on there) and email.  For the most part it will be a coin/electronics free family vacation (unless I find a computer to slip my mining thumb drive into, never leave home without that shit).

For the most part, talk to you all next week.  If a problem arises I'm sure someone will contact me and I'll get online somewhere and sort it out.   

Message those moderators !!!!! 

 Enjoy your vacation!

Sorry for my noobness like me... how does one import keys? And is there a way to make the search caps-insensitive? Thank you

 open the console and enter importprivkey privatekey label

be prepared to wait while it scans the blockchain for transactions (could take a while).  There is a noscan option for that command but it's inadviseable.  I think you would type false after your label.

 use the -i switch in vanitygen or oclvanitygen for case insensitive searches.

The only possibility is suicide. I understand that most people aren't willing to do this so we need to create a reddit sub where we can arrange to slaughter each other. I'm willing to kill eleven Bitcoiners at which point I wish to be murdered by another one.

 Yeah that's a little weird.  Also killing others is considered homicide.  I'm sure there are others on this forum who could help you... you know the rest.
7029  Bitcoin / Bitcoin Discussion / Re: What to do when BTC is overrun by a centralized mindset? on: August 22, 2016, 01:02:48 PM
So what do you do when Bitcoin is overrun by a centralized mindset?

After putting a few feelers out there it is obvious what you will do.

You will follow the status quo and do nothing to flush out the sickness.

Sometimes when you are infected you must find an antibiotic.

One with superior conductivity.

Have you found it yet?

Find the volume because it is out there in the charts.

Find the hedge to survive or risk going down with a sinking ship.

So many are about to walk the plank.

Maybe then they can be together with their beloved squid for eternity.



This is a rather poetic soliloquy;  more of a rant than a discussion.  Walking the plank is for mutineers and yet If we are all mutineers then certainly bitcoin collapse and it becomes a self-fulfilling prophecy.  Walking the plank isn't the right metaphor.   Also the squid reference doesn't mean anything to landlubbers like myself.  You need to rethink your campaign with your target audience in mind.  I'm sure there are people on the forum who could help you with this for a fee... in Bitcoin of course.

7031  Other / Archival / Re: BTC puzzle! 0.5 BTC on: August 22, 2016, 11:30:33 AM
what about the names? everybody seems to agree the it is the last name. why not the first letter of the first name?

For the Steve Jobs case, it was the last name, since the letter S can't be after the 5 in a private key. So we assumed that we need the last name of the other names.

sorry if this is a bit OT, but with S and 5 (also I and l i guess and maybe some other combinations) it is only possible to have one of those?
so if i have a 5 no S is possible afterwards and if i have an S no 5 is possible? do i get it right? maybe this can also help us to narrow it down.
and it would be nice to hear something about this. or at least where i can read up on the matter Smiley thx

 Okay I'll tell you what I know.  A private key in WIF (Wallet Import Format) is 51 characters in base58.  For Bitcoin mainnet, the WIF private key will always begin with a 5.  Why?
Because
 1. Take the ECDSA private key which can be any unsigned integer from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140
 2. and you place the network identifier (0x80 for bitcoin mainnet) in front. (by the way, 0x simply means hexadecimal format).
 3. You take this result and perform a SHA256 hash on it.
 4. Take the result of that and perform another SHA256 hash on it.
 5. Take the last 4 bytes of the previous result (used as a checksum) and add it to the end of the number in step 2
 6. and finally convert that hexadecimal number to base58 and you have the WIF private key.

Here is the lowest possible address with the network identifier and checksum added:
800000000000000000000000000000000000000000000000000000000000000001A85AA87E
and here is the largest:
80FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140F511BD7A

 As you can see, the range of values is limited by the use of the network identifier which is why when converted to base58, the result will begin with 5 and be limited to H, J or K for the second character.

Read about it here and here.

Now I expect some puzzle solution suggestions from you very soon!


thank you Smiley
and here i a hint from me. 25 could also be Celluloid instead of film. hope this helps Wink

 Celluoid?  I hadn't thought of that.  Thanks!  As soon as I'm home (if the puzzle hasn't been solved) I'll add that possibility.

I'm only asking since I made this mistake.  Did you test your program with a valid private key in WIF?

lol, imagine if my code was wrong all this time, i have ran the code for almost 70-100 million (each time 11 mil-5mil) Cheesy

but no i doubled checked it now and it was ok.
i went through This to create my code and after busting my ass to get it to work i found this written in c# with a nice NuGet package

i tested with the private key on wiki page and a couple from directory[dot]io and today i made a new Electrum wallet to double check it with compressed private keys too. all successful.

 Yes I can imagine... I ran through almost 300 million without realizing my program wasn't valid. 
Thanks for the information.  I'm going to check out the c program.
7033  Other / Archival / Re: BTC puzzle! 0.5 BTC on: August 21, 2016, 12:19:45 PM
i think i have worked more on my code and the interface than i have ever worked on the puzzle itself Cool

#master of xaml

but to be fair, i learned a lot in the process about base58 and also conversion to hex, also about multiplying TimeSpan so i am happy.

 I'm only asking since I made this mistake.  Did you test your program with a valid private key in WIF?
7034  Other / Archival / Re: BTC puzzle! 0.5 BTC on: August 20, 2016, 04:57:30 PM
Pretty much allot of work even for 0.5 BTC, just the last page is filled with clues, Good luck to those trying to decipher this thing.

it is not just about the prize you get, although i say $290 is a pretty good prize. but it is mostly about the game and solving it. you can call it a treasure hunt.

although what bothers me about this, is the fact that i am not so sure if this is a good puzzle with only one possible solution.

for example you can already see many people straggling about the answers like that plane picture many say "jet" others say "F16" "mig" or it can simply be "Plane" "Airplane" or "Fighter-plane-thingy"

 I am certain that the plane image can only be 3 letters.

let me explain about the Upper/Lower cases of my choice.
i say these colors of each picture should mean something too, and they don't look random to me (otherwise what is the point of similar colors Cheesy). so this is my key:
i choose a color and find a box that i am sure about the upper/lower state so i say the rest should be the same too for example since the box #1 is J all the same color should be Upper too.

color index : U=Upper L=Lower : reason index
0 : L : every other color has some reason to be U so i go with L on this color.
1 : U : 1
2 : U : 34
5 : U : 29&41&44
8 : U : 31

i think i will stick to this theory for now, but i may try your suggestions later too.
also the gist was updated. will run the code in the morning

 Interesting idea.  I hadn't considered the colours to mean anything.

I have been reading bits and pieces of this thread but not all so forgive me if I ask a question asked before but.... is there a way to run oclvanitygen across multiple cards, like as an ETH miner would / old setup?

C:\>oclvanitygen.exe -D 0:0 -D 0:1 -D 0:2 -D 0:3 -D 0:4 -D 0:5 1prefix

That's for 6 cards

thanks for the explanation.
so here is my updated code with 1,937,664 keys and nothing is right:
https://gist.github.com/Coding-Enthusiast/feeb2200b6201c94fec1bd5b704a2b67
(i will update this in the future if i find a different answer)

maybe others see what i don't see!

 That's nicely laid out.  I just finished night shift so I'm a little tired but I can contribute a few revisions.  First of all, you should only put capitals on proper nouns.

Code:
  

 4 +theKey[3] = new PKeyChar(new char[] { '3', 'p' });  #the symbol is of the miniscule Greek letter pi not Pi
 5 +theKey[4] = new PKeyChar('A');  # Atari is the name of a company and must have a capital
 6 +theKey[5] = new PKeyChar('p');  #parachute is not a proper noun
 7 +theKey[6] = new PKeyChar('j');  # jet is not a proper noun
 8 +theKey[7] = new PKeyChar('w'); # almost certainly this is a wing from the previous image
 
 10 +theKey[9] = new PKeyChar(new char[] { 'Y', 'y' });# The term yo-yo was deemed generic in the U.S. in 1965 maybe try both capital and miniscule for this
 
 12 +theKey[11] = new PKeyChar('i');  # an iron is not a proper noun
 
 16 +theKey[15] = new PKeyChar(new char[] { 'X', 'R', 'k', 'p', 'r', 'x' }); #try the minuscule for X and R as well as k for knee, and p for patella

 18 +theKey[17] = new PKeyChar(new char[] { 'R', 'S', 'r', 's' }); #sonar and radar can also be used without capitals 

 21 +theKey[20] = new PKeyChar('N'); # Nobel was a persons name (proper noun)

 22 +theKey[21] = new PKeyChar(new char[] { 'i', 'h', 's' });  #no capitals and added h for hockey skate
 23 +theKey[22] = new PKeyChar('X'); # probably capital
 24 +theKey[23] = new PKeyChar('Y'); # which means this is also capital
 25 +theKey[24] = new PKeyChar('i');  # igloo is not a proper noun
 26 +theKey[25] = new PKeyChar('f');  # film is not a proper noun
 27 +theKey[26] = new PKeyChar('G'); # Galileo is a proper noun

 29 +theKey[28] = new PKeyChar(The58Char.ToCharArray()); # I think this might be a wildcard so let's try all
 
 39 +theKey[38] = new PKeyChar(new char[] { 'W', 'w'});  #try both
 40 +theKey[39] = new PKeyChar('W', '8');  #this style was introduced with windows 8
   
 43 +theKey[42] = new PKeyChar('b'); #balloon is not a proper noun (perhaps try all too)
 
 
 46 +theKey[45] = new PKeyChar('E');  #Etch-a-Sketch needs a capital

 48 +theKey[47] = new PKeyChar('X');  # based on the clue layout, I'm now convinced this represents the element Xenon
 49 +theKey[48] = new PKeyChar('m'); #if it truly stands for lamp, use small letter (do you have capacity to make this a wildcard?)
 50 +theKey[49] = new PKeyChar('T');  # Tesla is the name of a company (and a family) it needs a capital
 51 +theKey[50] = new PKeyChar('m'); # mouse is a generic term so use the small letter


 Wish I could do more but I'm getting ready to go on a trip and I wont be able to take my computer with me ;(
Good luck!
