Hi Shorena, when i do this, it asks me to enter my password. which i do, it then proceeds to tell me this is an invalid address.
So its part of the wallet, the wallet is just fucked up somehow. Try restoring from seed again. How do i paste pictures in? it doesnt allow me to do so.
You have to upload them somewhere else and put the link (due to your rank it will not show). I use imgur.com |

Hi guys can you help me to sign message in electrum with 2 factor authentication because i am having a problem once i generate signature in signmessage with my address giving error after click sign message..
I hope someone can help about this.
electrum using 2fa? im never hear about it, im not use electrum, i use mycellium and coinbase, if you can backup your private key, maybe you can export it to mycellium and do sign message at mycellium. Can you link me if where can i get the download link the mycellium? Also i would like to ask if after i use mycellinium i can still get back it to electrum to use my address again in electrum? Looks like this is for android .. do you have any alternative to transfer the address? You simply cant sign with multi sig (or any pay to script hash) address. Your 2fa is very likey exactly that. You can export one private key and sign a message with it (electrum works fine for that as well). It would be for a different (version 1) address though. |

correct, it was in my recieve address at first, it then dissapeared after i clicked save. i cannot find it anywhere in my list of addresses.
Not even here?  Try signing a message with the address. If you can the wallet has the private key for it and its just an update problem. Here is a step by step for signing with electrum -> https://bitcointalk.org/index.php?topic=990345.0 |

Yes/No explanation
If a campaign has Yes/No as escrow status, it means that the person holding the funds also pays the participants. This is a conflict of interest, but shouldn't be a big problem if the person doing escrow is trusted.

Here are the details from blockr.io in regards to my transaction:
Hash
1VVNzb5kVDSLHAsYrxCuMbKv1bSisHDS2
Balance
0.35200000 BTC
Total received
0.36150000 BTC
Transactions
3
Unconfirmed
0.00000000 BTC
Note: Unconfirmed balance is not part of the address balance or total.
this amount is showing in that hash wallet when i copy and past it into electrum open/restore wallet. but is saying it is watch only.
Yes, because you copy pasted an address. That is how you create a watch only address. If I could spend your bitcoin because I had your address bitcoin wouldnt work, because no one could tell anyone their addresses. I have no recollection of ever creating a watchonly wallet. I have only ever used the one and havent had this issue in the past.
In my list of receiving addresses on my wallet i cannot find this particular one
If the address is not from your wallet, why did you use it for a withdrawal and expect the coins to end up in your wallet?
-snip-
so is this the withdrawl address you have set into bitbargans because this address is created last month and i think you also have its private key in any of your wallet brecause if you copyed it from someone other then it should be used multiple time but it is not.so tell me how many wallets do u have
There is no such thing. It was maybe used for the first time in a transaction last month.
"so is this the withdrawl address you have set into bitbargans because this address is created last month and i think you also have its private key in any of your wallet brecause if you copyed it from someone other then it should be used multiple time but it is not.so tell me how many wallets do u have"
Yes this is the address my electrum wallet generated for me when i opened it up earlier today.
I have around 3 wallets in total (one default and 1 that i used my seed key to open up which in turn duplicated it)
I have no recollection of setting up a watch only wallet. I have absolutely no idea how this random generated code came up, especially when it is linked to someone elses.
Now Im confused. You say its not in your list of addresses, but it was created by your wallet? |

Well for one you didnt check for all possible two symbol prefixes (missed capital letters) I did "-i": case insensitive. Missed that :C but the actual reason why there are only 2160 different possible address is different. There are 2256 private keys. The public key to each private key gets hashed with RIPEMD160 among another algorithm (SHA256) which has a 160 bit output. Thus the can never be more than 2160 addresses. It is assumed that each address has 296 private keys that allow spending coins from them. This might not be true for all keys as its unclear whether the distribution is uniform. Its possible that some addresses have 296+X keys while others have 296-X keys, where X is not zero. This doesn't explain why I don't find 1 public key for every private key. This is the other way around: 1 public key has a lot of (unknown!) private keys, but each private key should have 1 public key, right? If I run vanitygen for 1 second searching for all possible prefixes at 127 kkeys/s, why don't I get 127,000 keys? It should. Not sure, I dont get any numbers when I run it with -k 1, but its not 300k per second. Might be the output slowing it down.
See the picture above? Its about the physical(!) limitations of counting(!) to 2256. Thus its somewhat wrong as we only need to check 2160 (which is faster) and we are not counting (ECDSA math and hashes are slower than counting). The ballpark is still correct though. In my example above I even assumed 1022 attacks per second.
I don't understand what that picture should tell me. Thats impossible to use the entire energy our sun has left fueling the best possible computer and let it count to 2 256 By the way, what is it? Some virus or a star? Further, I don't quite understand how real are these physical limitations of counting, and what do they have to do with finding a collision? If there are 10 billion Bitcoin addresses, the chances of finding just one collision are multiplied by the number of already created addresses, right? In other words, if all possible addresses were created, then any address you generated would be a collision...
Let's assume for simplicity that a search in the database of existing addresses doesn't take time at all
IIRC its a dyson sphere around our sun. Its a theoretical concept of a civilization so advanced that it can build a sphere around a sun to harvest 100% (or very close to) of its energy output. The physical limitations assumed in the picture are the following. Take the thing that requires the least amount of energy to represent a bit in either a 0 or a 1 state. IIRC its the spin of some particle. This lowest possible amount of energy is defined by the law of thermodynamics. Now take a good estimate of what the sun can output in terms of energy and calculate how many bit flips you can fuel with that energy. The result is that you cant do enough bit flips to count to 2 256. Keep in mind that this is physics and my understanding of these things is limited. I personally think I understand the pictures point, but I dont like it. Mainly because 2 256 does not matter anyway and its not a good explanation without a deep knowledge of physics. Its essentially a "because physics says so" which is useless if you cant follow the argument. Anyway, trailing off. I assumed no lookup time and no other constrains. I also took half of all possible addresses and not all of them, because of the birthday paradox[1] which essentially means that you have a almost 100% chance of finding a collision after checking half of all possible hashes.

I am a newbie, I want to know about the best signature campaigns for newbie?
None. Campaigns that accept newbies nowadays pay bad rates and are mostly a waste of your time. Use the short time until you rank up to learn as much as you can so you can actually contribute to a discussion once you are at least member and can join a halfwhat decent campaign. Judging by your posting history and your current signature you will not follow my advice. Please dont start a crying thread in meta after your inevitable ban. |

Hi Guys, first time poster here.
I have been buying bitcoins for a few months now but only small transactions.
I bought £170 worth earlier (.353 btc)
Copied the electrum receiving address and pasted it into bitbargains send address.
Did they send the coins? Is the transaction confirmed? Can you post the transaction id? It has been several hours and nothing has come into my account, i checked the receiving address on electrum and the coins are in a watch only wallet. (I dont believe it is mine)
So you are watching someone elses address (why?) and send coins there? (why??) I have no idea how this happened and i am extremely worried. Can anyone advise on what i can do please  i can provide all proof that the coins were purchased by me ( appears on my bank statement, show my account on bitbargain etc.) i just need to know how to get them from this watch only wallet into my own wallet. You cant. A watch only wallet is one - as the word says - where you watch only, you cant spend. Its missing the crucial part (the private key). Electrum does not just generate these wallets, you have to specficially create it. How did you create the wallet exactly? |

Es ist geschafft! Mein Leib-Computerexperte war da und hat die Wallet aus Kapersky herausgekitzelt. So wie er mir das erklärt hat, hat er in Kaspersky nachgeschaut, was da gelöscht wurde. Mit dieser Info hat er dann wieder alles zurückgeholt. Entschuldigt meine unprofessionelle Ausdrucksweise. Außerdem hat sich herausgestellt, dass die Wallet vom Bitcoin-Programm automatisch in Dopbox gesichert wurde. Ihr seht schon, ich bin ein richtiger Antiexperte. Daher noch meine nächste laienhafte Frage: Ich kann in der Wallet nicht erkennen, wieviele Coins ich jetzt noch besitze. Und wie kann ich diese eventuell wieder zurückgewinnen, bzw. auf mein privates Konto überweisen?
Wallet in der Dropbox: Ich hoffe du hast ein gutes Password. Wieviele Bitcoin: unten links "Balance: ..." Bitcoin überweisen: Geht nicht, verkaufen. Bitcoin verkaufen: bitcoin.de |

I laughed for a good thirty seconds at that. Greatest excuse I've ever heard. Thanks. Now, go away.
While we're on topic,what if a user has no paid signature and actually likes a particular post and should he choose to repost it in other thread,would it still be eligible for a ban ? I know you can simply ['quote']['/quote'] the post but just what if ? Its very simple: If you didnt write it yourself, give a source (however you prefer to do so)
Anyone else noticed how hilariousandco becomes more like BadBear over time? -snip-
Now, go away.
No, go away.

So what's the name on the ransom note?
zepto, it's a new version of locky Tell your friend to contact their support. They might be willing to lower the price. They have in the past and their ... "customer" support is excellent. If you are afraid of any repercussions, write up a small statement and let your friend sign it. I dont think you have to worry about that though. |

Yes, thanks for the heads up. So what's going on here? Someone claimed I set up a bogus escrow and received some money? That's my address, and it's the one in my profile and the one I have registered with the 777 campaign. I didn't get any payments to that address lately other than campaign payments and bitcoin I bought.
It's too early in the morning for this. Really. I haven't even made coffee yet.
Looks like someone tries to throw shit at you. |

These chances are really high actually. If we write them in a more concise manner that would be 6.84 x 10^-38. Just for comparison, the top supercomputer as of today is capable of making 9.3 x 10^16 floating point calculations per second (and they are now talking about reaching 10^18 flops by 2020).
You're comparing apples with rainbows there... The values are not even remotely related to one another... how many floating point calcs you can do in a second, is not a number you can directly compare to the chances of 1billion users (who each have 10 addresses) having an address collision!!?!  Bear in mind... people aren't saying it isn't possible... as the odds are >0... they're just soooooooooooooooooooooo very tiny... that if it does happen, well... that's just "Bad Luck™" If people are afraid of this they should just never reuse addresses. This greatly limits the chances they lose a large amount of coins. The chance that it happens once is so tiny, what are the odds that you "guess" 100, 500 or 1000 addresses? |

-snip- 2^160 possible addresses Do I understand correctly that not all private keys have a valid public key? I ran this: ./vanitygen -i 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 1g 1h 1i 1j 1k 1l 1m 1n 1o 1p 1q 1r 1s 1t 1u 1v 1w 1x 1y 1z -o tempfile.txt -q -k for 11.345 seconds. It checks about 127 kkey/s, and found 5366 keys. That results in 473 keys/s being found, while 270 times more keys have been checked. Well for one you didnt check for all possible two symbol prefixes (missed capital letters), but the actual reason why there are only 2 160 different possible address is different. There are 2 256 private keys. The public key to each private key gets hashed with RIPEMD160 among another algorithm (SHA256) which has a 160 bit output. Thus the can never be more than 2 160 addresses. It is assumed that each address has 2 96 private keys that allow spending coins from them. This might not be true for all keys as its unclear whether the distribution is uniform. Its possible that some addresses have 2 96+X keys while others have 2 96-X keys, where X is not zero.
So the chances of a collision occurring in your scenario are approximately 0.000000000000000000000000000000000000684%
See why we don't consider collisions an issue?
These chances are really high actually. If we write them in a more concise manner that would be 6.84 x 10^-38. Just for comparison, the top supercomputer as of today is capable of making 9.3 x 10^16 floating point calculations per second (and they are now talking about reaching 10^18 flops by 2020). Yes, I know that generating an address requires many calculations but, on the other hand, someone could develop a highly specialized chip for doing just that. In fact, I expected the chances to be way lower than that, and way lower is actually an underestimation of being truly lower. Somehow, I thought the odds of a collision should be on the order of something like 10^-1000. But even that I wouldn't consider as quite impossible on a long enough timeline... And don't forget about pure luck See the picture above? Its about the physical(!) limitations of counting(!) to 2 256. Thus its somewhat wrong as we only need to check 2 160 (which is faster) and we are not counting (ECDSA math and hashes are slower than counting). The ballpark is still correct though. In my example above I even assumed 10 22 attacks per second. Brute-Force is not possible. The only way to attack bitcoin is to find a flaw. In terms of math you need a shortcut. Its easy to calculate A+5=C for any A. If you know the result C you can easily reverse the input from that. This is currently not possible for private key -> public key calculations. Currently we can only select a random private key, calculate the public key and check the result. These shortcuts will be found and when that day comes bitcoin will need to adapt. They will however not be found over night (see e.g. RSA and factorisation), but there will be gradual improvement from 2 256 steps to maybe 2 192 and enough time to adapt to a different algorihm[1]. [1] a sidenote: SegWit actually make this super easy. |

Nothing is checked, not with online wallets, not with services (e.g. blockchain.info), not offline, no where. A collision is not prevented, its just so unlikely that it can be considered impossible. Some GPU system create over 60Million keys per second, thats not possible when a check would be needed. What would the check even accomplish? I could still spend your funds.
How unlikely is this? I mean if it is today considered unlikely, what will happen tomorrow when, say, some system could create not just 60M keys per second but 60MM keys per second (and check real-time against existing addresses at that)? Wouldn't this render Bitcoin useless and worthless immediately? To me, it is always fishy when something is considered impossible, since it has a tendency to actually happen one day... "640K ought to be enough for anybody" I assume with 60MM you mean 60Terrakeys/sec (6*10 13). Lets assume this is what a tomorrow TM GPU can do and that there are a billion (10 9) people brute forcing keys. They somehow manage to never generate the same keys among them. How long would they need to create half of all possible version 1 bitcoin addresses? Well there are 2 160 possible addresses and the attackers can check 6*10 13+9 per second. They would reach half after 2 159/6*10 22 ~ 1.21791*10 25 seconds or ~ 3.8619 *10 17 (386,199,274,197,452,360) years. calculation: https://www.wolframalpha.com/input/?i=(2%5E159%2F(6*10%5E22))%2F(60*60*24*365) (the link breaks due to the brackets, copy pasta) |

So I'm doing some service and paying for 5000 satoshi each, unfortunately the fee in blockchain will eat all my funds when I try to send it, you guys have any idea of a website that gives low fee or atleast no fee at all. I saw other gambling site that they wont charge fees but I forgot their names. If you can give that will really help me. Thanks
get higher payouts. Let me elaborate a bit more:
You can use a service that charges no fee, but they will charge you otherwise (e.g. via adds or selling your profile) and you usually will have no control over your private keys. Bitcoin transactions on the actual blockchain have a cost. You can try to skip it, but eventually it will create more and more problems for you. See #1 here -> https://bitcointalk.org/index.php?topic=1044399.0 for more. What service is this? One woudl be xapo, dont tell me I have not warned you. |

i still dont know what this thread does i dont understand It is explained in the first page in the first post https://bitcointalk.org/index.php?topic=996318.msg10820715#msg10820715Only you have the access to your BTC address, so if anyone tried to hack your Bitcointalk account and if they try to ask for anyone for money or pretend to be you, one can simply ask to sign a message using the staked BTC address. ...as long as you are using a proper wallet or a good service that gives you access to the private keys. |
