Hello forum, I've read and read, and studied and learned.. for about 2 weeks... but now I gotta ask a few very beginner questions  Hello bitcointalk! My story, I have some BTC / ETH and ETC on QuadrigaCX (Vancouver based, Canadian exchange) It was a great option for a crypto noob, to lose my crypto virginity. After some study, I had finally been convinced I want some of the action. I got in about a week or two before the Ethereum HardFork, and actually didn't even know it was coming. I got confused trying to figure out what exactly happened/what the dao was, and in fact am still kinda a lil confused about it all, but I have read enough articles to somewhat have a basic understanding of the current situation. Luckily for me, QuadCX provided us with ETC's, as I heard some exchanges didn't handout any ETC to people who had ETH. Without getting to side tracked, let me get to some ?'s. There is an issue with the fork where moving one coin, say ETH, could also move the other fork, ETC. So if you do withdraw your ETH and ETC, you have to be careful to not accidentally send both ETH and ETC to someone. I don't know how the exchange will handle that though. They could be sending you post fork coins or pre-fork coins. If it is pre-fork coins, then you will have to be aware that this issue will probably affect you. Now, I'm considering taking my coins off QuadCX and moving them into a wallet. I read about some horror stories/scams on here, of exchanges going down or never paying out when people ask for withdraws. It this a smart move? I'm concerned, if I move my crypto into a wallet can that software get hacked as well? I'd like to move to 2sV (2 step verification) wallet, as I think that'd have better security.
If this is dumb, and I should just leave my coins on the exchange, pls let me know.
Yes, you should definitely move your coins off of the exchange. Exchanges are not really meant to be wallets. You should also use a desktop wallets. Desktop wallets do not have any sort of 2 factor authentication, but they also mean that you do not have to trust any other service with your money. Desktop wallets put you in control of your own money, so you must be careful and attentive if you have a desktop wallets. They cannot be hacked; the only way you can get any of your coins stolen is by somehow getting malware on your computer. You should have a modern and up to date antivirus, making sure that your computer is always clean. Another reason I wanna get familiar with crypto wallets is I wanna purchase Ripple. I'm thinking either with fiat, or ETC. TBH, if I knew how to move my ETC to Poloniex, I'd already have spent 25% of my ETC on buying XRP, then sent the XRP to a XRP wallet... but I'm not that crypto savy yet. As far as I know, this wouldn't affect my current ETH in anyway. True? Learning about Ripple, I learned a little bit about the outdated Ripple Trade, then about GateHub, and how Ripple Trade accounts, were moved to GateHub.. So GateHub is a wallet+exchange? Also, I read this.. http://blog.gatehub.net/post/147641039422/gatehub-fifth-handling-of-the-ethereum-hard-forkWhich really questions my desire to do business with them at all. ( Did they choose a "winning chain" yet? Has this resolved yet? Isn't this scammy?) I don't know much about Ripple, so I can't help you there. Terminoligy ?'s
HODLer = someone who never sells, like a crypto hoarder?
To hodl is to hold your coins without ever spending them in the hopes that the price increases substantially. Basically hoarding. FUD = ? No clue.
Fear Uncertainty, and Doubt. It usually means misinformation, and lies spread by people in order to push a certain agenda. You will see a lot of this in the block size debates. KYC = something to do with a transaction, that has ID built into it?
It has nothing to do with transactions and everything to do with an exchange. Exchanges usually have to follow Anti-Money Laundering (AML) and Know Your Customer (KYC) laws. This means that they will have to collect your personal information in order to verify your identity and make sure that you are not money laundering or doing anything shady. |

Sometimes I get this error: Traceback (most recent call last):

Also, I have had it running since yesterday but it seems like it isn't getting any new blocks even though Core is. And it doesn't update when I restart DB and Qt. |

What we're basically trying to do here is take ownership of the @diginomics twitter handle. If there is an easier way to do this, then I am all ears and willing to pay handsomely for a solution.
You could always try using this form: https://support.twitter.com/forms/impersonation. Since you own the diginomics.com domain, it may be possible to do so, especially with the account being suspended right now. You would have to say that the person who owns that account is squatting on your name. |
|
|
|
Yes. Clearly they were using a third party service to automate tweets and got suspended for it.
Nice find.
I wonder if there is a way to reinstate the handle and take ownership of it?
Try talking to twitter's customer support and see if they will allow that. Perhaps they will, as many sites do recycle usernames if they remained unused for too long. It looks like that account was probably suspended ~5 years ago. |

You need to generate more addresses so that Armory knows that they were used. When you restore, it generates a predefined number of addresses from the seed, so it may not know of more addresses past that predefined limit.
Open your wallet and double click the wallet to open the wallet properties. Then click the blue text next to "Addresses Used". This will open up a window for "extend address pool". There are instructions here about how to do that. Enter a large number into the box at the bottom and click compute. Repeat until you start getting empty addresses.

How did you find the email address length and the username?
|

This script generates uncompressed addresses, but i want i to create compressed addresses.
Adding pubkey_point = compress(pubkey_point)
The line before address = pubkey_to_address(pubkey_point) should work. |
|
|
|
Does anyone know how this script has to look for compressed addresses?
Your question is not quite clear. What are you asking? |

i reseted the blockchain and transactions (reseted from date of first transaction).
the faulty transaction that hasn't been confirmed is nowhere to be seen anymore. all i see is 2 incoming transactions from november 2013 of around 3.3.8 BTC.
That is what should happen. That transaction has already been dropped by the network. What you did was tell your wallet to also forget about it, thus allowing you to spend those Bitcoin again. It should be as if that transaction had never happened. however the balance of my the wallet now says 0.0001 BTC and that really freaks me out... i mean how can this be when there are only incoming and no outgoing transactions? oh man.....
That is strange. Can you post a screenshot? Are you sure that it is fully synced? |

Should be multibit HD which should have a button "repair wallet" that should do it.
If Im wrong and its multibit classic "reset and rescan blockchain" (something along those lines) should do it.
Yep. Looks like those should fix it. They will rescan the entire blockchain and remove your unconfirmed transactions. |

That isn't the actual raw transaction... But, you can see that the second output there of 3.37690527 is your change output. I'm guessing that your wallet says you have 3.37690527 and you are trying to spend from it. However, that is the change output and it is tied up in this unconfirmed transaction. it says in multibit that my balance is 3.37700529. any idea what i need to do to fix this? So I did a little bit of digging, and it looks like your transaction fee is too low. It is paying somewhere between 30 and 40 satoshis per byte, which, although not that low, isn't high enough to get you fast confirmations. When you sent it a month ago, the state of the network may have been different and may have required an even higher fee. In order to fix this, you need to make your wallet forget that it made that transaction in the first place. I'm looking into how to do this. Which version of MultiBit are you using? |

I just looked at the transaction at blockchain.info and blockexplorer.com. Both can't find the transaction and I strongly believe, that I mistakenly send the transaction to a non existing adress...
That is not possible, Multibit would not allow it. Rather what likely happened was that the fee was too low so that many nodes and the block explorer nodes did not accept the transaction. Would the raw transaction text help you and is that something that I can share openly here?
Yes and yes. The transaction does not leak private information, it is meant to be shared by every single node on the network. |

I have googled quite a bit but haven't been able to fix the issue. It might have something to do with an outgoing transcation from the Multibit wallet, that didn't go trought. It says under transactions "This transaction is not yet confirmed. Seen by 1 peer." The mentioned transaction was a very small transaction (around 2 dollars only) and is more than a month old. The value of of my actual wallet balance is many times the value of this unconfirmed transaction, so I don't see how this stuck transaction can block all my funds?
Any help is appreciated!
It can block your funds because of change. When you spend Bitcoin, you are actually not spending a balance of an address but rather transaction outputs. These outputs are like dollar bills, they can only be spent in full. In order to send the exact amount, you have to collect change, just like you would with dollar bills. This unconfirmed transaction could be spending from a large output and had to produce a change output. That change may be what is preventing you from being able to send more money because the change output is still unconfirmed. Edit: Dang, shorena beat me to it. |

Now that I think about it, it should create the dbdir if it's missing.
It should definitely do that. So what looks like is happening is that if the databases folder was empty and I had to create it, then it will segfault when Qt starts up. |
|
|
|
On the latest dev, whenever I start the DB and then start Qt, as soon as Qt is up, the DB segfaults.
Delete your db and try again. When I delete the databases folder, it doesn't seem able to be creating a new one, instead it tells me the folder cannot be found. I have to create it by hand. Note: I am using a custom datadir and satoshi-datadir. And I'm on mainnet. Edit: I think it is a problem with my custom datadir. It works find on default. |

Yes. You check the source code. If you don't think the developer is trustworthy, check the source code and build it yourself from source.
there are many problems with what you just said. 1) for example Core is in C++ (if i am not mistaken), Electrum is in Python,... and in order to check the source codes you have to know these programming languages, or at least have some knowledge in any programming language to be able to make heads or tails of what is going on. Yes, but most major software have sufficient documentation and commenting in the code to make it easier to understand. You also don't need to be an expert in every language to understand what is happening, you just need to know one language that is related (e.g. Java is related to C/C++, Python, C#) to be able to read the code. ' 2) these are fairly big project so going through the code is going to take a very long time if you are not a veteran programmer and even if you are it still needs a long time.
Not necessarily. Even though a project may be "big", they usually have decent documentation (code comments) to make understanding what each function should do a lot easier. Furthermore, if you have a starting point that you can trust, then you can just check each code commit from that point on which will be much easier to check than to analyze the whole source code. 3) also building from the source code is not recommended for everybody especially when a newbie is asking for it , because they may break something and encounter a lot more problems and there aren't really detailed walkthroughs available to use them to compile the wallet.
How so? Building from source for the major wallets is well documented and very easy to do. There isn't anything you can break without actually changing the code. the only solution that is left for regular users (which are the majority of bitcoin users) is to trust the developers based on their history and how long their wallet was around.
Or you can have someone who is able to read code audit the code themselves. You do not have to trust the developer, you can have someone else you trust to check the code for you. |
