I received confirmation email just after I registered, received it on my spam folder. This maven software will not attract poker players imo, but the free 10k chips will.
At this point, i can login to their system, but i can only read this text: Confirmation Email Sent.
Please check your email and confirm email address.
If you see no email from us, please check your spam box and make sure you mark our email as ‘Not spam’.
I double-checked, but never received the confirmation email (i did check the spam folder aswell)... OP, can you resend this email, or do a manual activation? |

I tried to sign up with username mocacinno, but i didn't receive the confirmation mail (so far), it's not in my spam either... Since your system indicates the email isn't really necessary, i tried logging in without confirming my mail, but i was confronted with following error: Server Error in '/' Application.

There is not much wallet providers can do to stamp out double spending but there is a lot the receiver can do to avoid getting scammed. Wait for at least two confirmations before releasing your goods/service.
I thing one wallet provider can stop double spending and due to this all service provider have keep atleast 1 conformation before they deliver One wallet creator could, in theory, write a wallet that didn't allowed you to export your private keys AND didn't allowed you to use the same inputs as the inputs used for an already broadcasted but unconfirmed transaction. However, the protocol would still allow such double spends to be generated by everybody else. Also, such a wallet would actually make it very hard (if not impossible) to fix any problems with, 0-fee or to low fee transactions. |

So, it's about the same power draw/Ghs as the S9, and you get a little more bang for your buck (the current batch of S9 goes for $1600 hashing at 12.93 Th/s)

The screenshot shows you're connected to us5.einfachmalnettsein.de port 50002 via SSL, when i try this server/port i simple cannot connect...
I'm currently connected to ELECTRUM.jdubya.info port 50002 using SSL and it works perfectly
This being said, i'm not an expert, but i assume you already checked the diskspace, restarted, doublechecked the version, tryd with an admin-account,... ?

Actually even some of the online wallet providers disable custom fee feature double spend can't be stopped as there are hardware, desktop wallets from where we can actually use command to send input with custom fee.
definitely right,and that's why a people are getting recommended to wait atleast 1 confirmation to come and considering it as a transaction that have been completed if the confirmation just arrived rather than risking the money and facing the double spend problem I guess it depends on a lot of things... If you're running a coffee shop, selling a cup of coffee for $2/piece, you might allow 0-conf. If you would only accept FIAT, you might as well run into people leaving without paying (stealing) or using fake money (counterfeiting). It's just the cost of doing business. Sometimes people will try to double spend, just give your security images to the police, file a complaint and never serve the scammer again. If you sell online subscriptions (like a membership to a streaming service you own), you could also accept 0-conf, since you could just cancell the subscription if the transaction isn't confirmed in 2 hours or something. If you're selling more expensive, physical objects, i would defenately wait for 1 confirmation before sending the good/letting the client leave. For really expensive stuff (cars, houses,...) i'd even consider waiting 10-15 confirmations, so there's virtually no chance of a fork. |

and why any wallet provide si not stopping this hacking trick
actually it's not wallet's providers fault,they just enabling the self customization fee to add more flexibility to the wallet users because as you know they want to set the fee whatever the amount they want,but unfortunately this feature is just getting misused by people,so there's born double spend Actually even some of the online wallet providers disable custom fee feature double spend can't be stopped as there are hardware, desktop wallets from where we can actually use command to send input with custom fee. What these days web wallets have is recommended fee which is very useful for the one who want to get their transaction confirmed within next block or 10 minute. thank you so its not any illegal thing so many can do use this option to be rich .don't you think ?? Actually, if you pay for goods or services, receive said good or service, double spend the input for the payment transaction to create an output that doesn't go to the vendors wallet, I'm pretty sure its considered stealing in most (if not all) cultures  Double spending in itself is not illegal, but it CAN be used for illegal purposes. ok got your point now ..thanks so in short it can be use for legal purpose or illegal purpose also That is correct. A simplified explanation could be given like this: - bitcoin is a decentral database, the data in this database is stored in blocks. - the ammount of bitcoins you own is the sum of the input records stored in the database - when you send bitcoins to somebody, you create a transaction. This transaction is a piece of text in which you specify which of your input records you'll use to create an output record (this output will be seen as an input record for the receiver's wallet). - once you've created a transaction, it's broadcasted to the network. At this point, the transaction is unconfirmed (it's not stored in a block, it just resides in the memory of the nodes. It is unconfirmed and can be dropped/forgotten/double spent at any given moment). - a double spend is when you repeat the process: create a second transaction USING THE SAME inputs. - the miner now has a choice: he/she either adds the first transaction to a block OR the second transaction. Each input can only be used once, so when he adds the first transaction, the second one will be "cancelled" (and vice versa). The miner usually choses the transaction that has the highest fee. SOOOOOO.... This can be really usefull when, for example, you created a transaction with a very low (or no) fee, and it's stuck (unconfirmed) for hours (or days). You can create a second transaction, using the same inputs, but with a decent fee... This new transaction can be confirmed much faster, and cancel out the stuck transaction. Offcourse, the same principle can be applied when buying stuff from a 0-confirmation vendor... Pay him, and before the transaction is added to a block, broadcast a second transaction using the same inputs, but outputs going to YOUR wallet instead of the vendor's... This way, the transaction with output to the vendor will be "cancelled", and the funds are re-routed to your own wallet.... You basically scammed the vendor at this point, since the transaction with outputs to his wallet will never be added to a block, so he wasn't payed. Once again: this is a simplified explanation... There's a lot more to it, i've actually left out a lot of important stuff in this explanation!!! |

After reviewing the tx ID, I have to agree with Jhanzo.
I guess its best to contact the vendor and see if he allows you to create a second transaction with the remainder of the funds

Hi,
I'm new to electrum and am completely confused by what has happened. I created an electrum wallet. I then purchased 0.1 btc from bittylicious. The [Suspicious link removed]ived in my wallet within minutes, so far so good. I then proceeded to send 0.0686 btc to a marketplace to make a purchase using the marketplace wallet address given which I copied and pasted into the "pay to" box in my wallet. I then entered the amount to be sent and description then clicked send. Bizarrely, the btc did not arrive in the vendors wallet. On checking I can see that electrum sent 0.1816 instead of 0.0686. I truly do not know why this happened as I double checked the amount. Further, It turns out that 0.1816 is too small an amount to be deposited in the vendors wallet.
My questions are: Did I do something wrong as I am a newbie to electrum? Further, it is possible to retrieve the 0.01816 btc or is that lost to the ether? I have used bitcoin twice before without problems, but this is the first time I'm using a desktop wallet. Can anyone help me out here, I would be most grateful, thanks in advance.
Incidentally I can see a balance of 99.8184 in my wallet.
If i understand you correctly, you did send 0.01816 BTC, but the vendor has a rule which states he only accept bigger inputs. In reality, you have sent 0.01816, his software just doesn't recognizes this input because it's to small. If this is the case, you can try to ask the vendor for 0.01816 BTC, provide the txid. It's up to him wether or not he'll refund you tough (BTC is irreversible, so it's up to his/her goodwill). If i misunderstood the situation, it would help if you posted a txid (open electrum -> go to the history tab -> right click on the transaction -> copy ID to clipboard -> paste the txid in this thread) |

I am currently an economics major and have zero experience is programming or software development or network security. If I wanted to be an expert in blockchain technology with the ultimate goal of creating a blockchain unicorn sometime down the line, how does one chart the course?
I suppose by reading satoshi's whitepaper 1, then browse the bitcoin wiki 2 and this forum 3... Maybe by cloning an altcoin and creating your own alt just to learn the inner workings references: 1) https://bitcoin.org/bitcoin.pdf2) https://en.bitcoin.it/wiki/Main_Page3) https://bitcointalk.org |

An interesting idear, how would you handle website updates? You would need to make a new version of the page and create another 3 transactions using OP_RETURN to point to the updated version i guess...
Also, the concept will probably only work as long as enough people keep on seeding the page. Offcourse, it's really small so i guess most people won't mind doing this (if the page itself is usefull)

How they can look into the service, when the service will be available this week for first time ?
I don't really know, nor care, when they opened doors... Fact is the domain was registered in march 2016, so they have been around for a while: http://whois.domaintools.com/avalon-life.comAL does not have 2 Mining Farms in Costa Rica only 1 and 1 in Switzerland (so better do a research next time before telling others the untruth)
A quote, directly from the FAQ: https://web.archive.org/web/20160824120613/http://partner.avalon-life.com/en/faq/Is Avalon a “Cloud” mining company?
No. Avalon Life has 2 mining equipment in Costa Rica and other plants are in the planning stage around the world. Thus, we offer our customers and partners the opportunity to participate in physical mining. Cloud mining companies source your “mining power” mostly from traders, if at all. Mostly, only used “coins” are paid back in installments and the pool of “depositors” ensures supplies, which is the same as an illegal Ponzi system. Avalon Life is leading the way on real mining.
Better, think twice before telling untruth or bad experience in the past with other companies. You can't compare AL because there is no competioner to compare. Not even a single one  I have never actually said this service is a scam, just that i trust the 3 DT members that already tagged the owner. Is it safe to assume you're either an affiliate or an alt-account of the owner? |

hi i recent found some thing which is quite new to me is double spend transaction ..
any one send fund with quite low fee and this transaction will struck and after some time it will be return toy ur wallet ..
some trick this and sue as for there benefit and use not now but somehow they use more fee and sen that fund to differ account so tey got double benefit ..due to which all gambling company now have 1 confirmation deposit otherwise before the have not confirmation ..
do you know how this is happening ??
and why any wallet provide si not stopping this hacking trick
It's not new, it's not a hacking trick... It's basically how bitcoin works. It's a rather easy thing to do and it has legitimate uses. To create a double spend, just create a transaction, broadcast it. Afterwards, generate a new transaction using the same inputs, but with a higher fee, sign the transaction and also broadcast it. KnightDK even created a java tool to automate the process for you if you want to. EDIT: https://bitcointalk.org/index.php?topic=1506632.0? |

I have sent you a private message with the id transzaction
Received it. I'm not at my desk at the moment, but this evening I'll look into the problem and send you some feedback over PM |

OP, can you post the transaction id's, that way it would be easyer to see if something is wrong with the transaction in question.
What is the use of the transaction ids, when the op have clearly mentioned that he has not sync the wallet fully and even he have not given any transaction charges in the transaction then how can you expect that the transaction will get confirmation from any block. It is totally useless the transaction will get cancelled after some days. Well.... For example: bitcoin core keeps on rebroadcasting any unconfirmed transaction untill you tell it to stop doing that. I'm just not completely sure if the OP knows sufficient about bitcoin to express himself properly... when he says, and i quote 'The tranzaciones are unconfirmed', it looks to me like the transaction was generated and broadcasted, but there might be something wrong... On the other hand, his wallet might be not synced yet, so the transaction might not even be broadcasted to begin with. In the end, i can't try to give him usefull advice if i cannot look at the transaction. That way i can see if it's broadcasted, if some nodes know about the transaction, if the fees are OK, if they use unconfirmed inputs, if it's a double spend,... Without a tx id, we're just guessing here. (IMHO) |

https://bitcointalk.org/index.php?action=profile;u=387329laiyskylone has liqui exchange in his signature, the original ann-post for the hybridmixer sigcampaign promised to pay out to the liqui-exchange deposit address of the sigcampaign members (IIRC). This text was edited out pretty soon, but i was one of the first people who read the OP of their sig-announce thread, and i seem to remember it. Also, IIRC, liqui-exchange also ran a promo giving away 1 LTC Coincidence???
