Yes sure. This was another thing I thought before, but I was told that mostly transactions on the network with multiple input addresses aren't CoinJoin operations (and from this I was assuming to always link input addresses).
This is a common misconception. Even here on bitcointalk accounts are linked by spend linked addresses, which could be CoinJoin TX. I would argue that a human could probably identify a CoinJoin (just by the larger number of inputs and outputs), but not reliably. I remember there was a paper about CoinJoin and they just assumed that 5 or more inputs are CoinJoin, because they couldnt be sure and couldnt check all TX by hand either. We can also view it this way, instead of trying to use the CoinJoin (which has it's disadvantages) the splitting of the transaction could take place instead.
CoinJoin would mix some entities (and maybe make some algorithms think it its only one entity), while the splitting technique avoids the linking at all.
But isnt that the point of anonymity? To blend in with the masses in a way that makes your payments intertwined with everyone elses. That way its impossible to find a single person, not because there are no links, but because there are links from (almost) everyone to (almost) everyone. A CoinJoin implementation in more wallets than just bc.i would be a great step and AFAIK Samourai wallet and/or Mycelium devs are working on that. Mycelium will implement the code once its finished. I think it would go be good to remove the "only criminals need anonymity" stigma though, as it seems many attempts to get this rolling failed because they required high skill and(!) high user participation to work[1].

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

hmm, I don't/didn't see anything about fees. Is that bad? Otherwise it just seems like a waiting game at the moment.
If you have sweeped the funds already then the bitcoins are in your electrum wallet already, just go to History tab, you'll see your transaction there, right click on it and click view on block explorer, that will show you how much fee was added and based on that you can estimate how long will it take for your Tx to get confirmed. Also, make sure to keep backup of your Seed. You could pass your TXID over to us, we can help you estimate the TX time. I would recommend storing your bitcoin in electrum for as little time as possible, and put your coins back onto core. Core is safer, and you've already said you have a relatively large sum of coins? Id say electrum is fine, esp. if you cant get core to sync (like OP). To follow up on your question about the TX ID, maybe @Samorr you can post the address you initially received the coins on. This would allow us to follow the transaction trail and give you an estimate when the TX should confirm. Given the time that passed, it might already be confirmed though. |

I used Electrum last night to run my coins thru.. Sent back to my wallet and now the coins are sitting in some random wallet, yet untouched... And i am unsure what to do about this
Electrum, PM me if theres anything you can do to help please, I have all sorts of documentation to prove everything.
Any help from anyone is greatly appreciated.
Chances are higher to get help if you explain better what happened. Do you have a TX ID? It sounds to me like you had a change output. |

How long did it take until the TX appeared again? about 6 hours, It seams to get a new date and time around 19:00 hours (UK time) daily. This should give us enough time to double spend the coins. Do you can have coin control enabled in core? sorry, what? I have QT 5.5.0 QT just handles the GUI, you find your bitcoin core version via Help -> Debug Window -> Information or Help -> About Bitcoin Core Anyway, with QT 5.5 you should have a more recent version that has coin control. Coin control allows you to manually select which inputs (formerly received coins) you spend. In order to double spend the TX you could e.g. spend all coins you received on 1Cckp9QR3C13aUBipyU6YQnUNTHXxqFzU (should be 0.06767325). You enable coin control via: Settings -> Options -> Wallet It might ne a restart, dont know. Im thinking a double spend on one of the inputs I would appreciate any advice you think i should try, I would need some guidance just to make sure I am doing it right. At time of writing it has a new time stamp of 2016-03-08 13:54:18 so yes, someone is doing it I feel. Now with coin control enabled: #1 do the zapwallettxes routine again including step #4 #2 instead of step #5 create a TX once you are synced. You will find a new button in the send tab called "Inputs..." click on it and it will open the inputs you can spend. Select List mode, sort by addresses (or amount) and search for the 0.06767325 you received on 1Cckp9QR3C13aUBipyU6YQnUNTHXxqFzU. Select it by clicking on the checkbox on the far left. It should be the only input for that address and have >1865 confirmations. Close the window and confirm the selection with "ok" Now create a TX as usual and send the coins to yourself. Make sure the fee is high enough (currentky ~44-48 satoshi per byte). Alternativly select more inputs and create a TX you actually want to create, just make sure this input is also selected. |

Hi, I m having a little issue when running bitcoind. I downloaded sourcecode and both bitcoind and bitcoin-qt were compiled by myself.
i just run bitcoind -daemon to download blocks
The thing is that after the first hour of block downloading, my 4 CPU begin to work at rates over 95 % and RAM reaches 44% ( I got 8GB ). I m working with GNU/Linux Trisquel Belenos, which is essentially Ubuntu from FSF, then when I try to check out with bitcoin-cli getinfo, it does not answers back the query as usual, and the command line just blinks. So, I Kill bitcoind, and the bitcoin-cli comes back, of course saying there´s no response from server. If I restart the process ( without restarting computer ). well the overload happens again after few minutes. I don´t feel like safe leaving blockchain downloading if this strange overloads are happening to me.
Is there something I should configure?.
Can you post your debug.log? Its in ~/.bitcoin same as the other files. Is there any way of setting a limit of CPU usage for this process?.
You can limit the cores used, yes. Im not entirely sure core is not just verifying blocks though. what could be wrong or what should I check, it is just that I don´t know what to do.
I m under risk of machine physical damage, leaving the computer working at these rates?.
I would appreciate a lot any kind of help, so thanks in advance to those who could say something back. Kind regards.
You only risk physical damage if your machine is insufficiently cooled. The initial download and verification puts a lot of strain on your CPU, disk and bandwith. The 4 GB memory usage might just be cached data or did you increase your database cache (with e.g. dbcache=2048 in the bitcoin.conf file)? |

It's happening again today. Thought you would want to know.
Yep, had it as well. AFAIK there was no answer from theymos on this. It might be an (server-) ISP problem. |

@mexxer-2Additionally you could run 5000 nodes for only $50k monthly (IIRC the price is 10$ for a node) using their service. It does seem nice, doesn't it?
Well, one could do it for a cheaper rate if one abuses the "free" trial, amazon gives AFAIK you cant even sync properly on their free nodes before you run out of your monthly CPU quota.
@ATguyA DDoS that takes down routers at the ISP cannot be mitigated at the local server level.
When/where did that happen? You cant just ban offensive IPs, they overflow traffic with UDP packets and similar, thus unless your connection can handle more traffic than they send at you there is no defence for home user. That does not answer my question and Im not entirely sure an UDP flood attack against the large number of classic nodes is possible. Im pretty sure the attacker would need more bandwidth to exhaust the nodes. I also have seen not a single report on this, same as "ISPs get attacked" claim. I do however have seen several people defend against attacks by simple blocking the attackers (>400) IP addresses on their firewall in an automated fashion. I have linked it upthread. I dont care about could be, I want to know whats actually happening.
@frankyId say Hetzner is pretty well know. I also agree that the "sybill attack cries" are not called for.
@Zitdadast-snip-
That is the reason I do not run the Classic node in my home computer. I think DDoS should be punished by justice.
AFAIK its against the law in most countries. There is however little you can do about it as these attacks typically are done with bot networks and the origin IP probably has no idea whats going on.
@ETFbitcoinLots of number nodes doesn't mean classic has lots of supporters now, there's no point if miners don't use classic and there aren't any real classic supporter. Also, there's some way to run lots of nodes with low prices. I heard some people run full nodes in $2 VPS  2 USD might be a bit low, but Im also a bit picky what to use. 8 EUR/m is certainly possible.

Something is wrong, I call foul
While higher number of Classic nodes compared to Core nodes are on amazon cloud, the reason is the DDoS attacks where only Classic nodes are targetted which amazon cloud has good protection for. I doubt that, the DDoS can easily be defended with fail2ban[1]. It would be easier to install a very common admin and protection tool you should have anyway (even if you just use it to defend against SSH brute force attacks) than to move the entire server. Try run Classic node home and the chances are you wont be able to use internet when you need it the most because of DDoS - so your forced to set up node on cloud hosting with good DDoS protection if you want keep the Bitcoin network healthy.
I call DDoS crimminal, not just foul.
A actually distributed DoS (as in ran by multiple people and not a bought bot net) is seen as a form of political protest by some. I do agree however that hiring a bot net to attack classic is a stupid idea, whoever is behind it.

Hello,
how install bitcoind to hosting?
i want install bitcoind to hosting.. but i don't know how make it.
if you can, please give instruction or manual.
please help me.
Thanks!
What OS in which version does it run? Let me add to that: How can you access the server? SSH? |

@Bit1334271Today first time here on this forum and after reading this all very have some good information about this system now just want to ask which wallet is good and easy to use without too much download Thanks Shorena for this all hard work  If you are looking for a small or slim wallet I would go with the most common ones, Electrum or Multibit HD. There are more and I dont know all though, so maybe take a look here[1] and see if you find something that suits your needs. [1] https://bitcoin.org/en/choose-your-wallet
@Lutpin0 as expected.

Make sure the expression is valid for a bitcoin address. You can search for [O0l] without ever finding a result.
That would actually be a good improvement for vanitygen, to do a validation step to ensure that what's being looked for actually could match a bitcoin address. I haven't thought about the completeness of the problem but at the very least you could (as you point out) rule out any expressions which explicitly look for [O0I]. I don't think I have the code checked out at the moment or I'd consider submitting a pull request myself. It does: Invalid Character 'I' in prefix '1BIG' I guess it depends on what you actually entered as neiter "small ell" not "big eye" are filtered for me. Are you using -r? $ ./vanitygen -r '1BlG'

All the vanity addresses are like : 1NAMExxxxxxxxxxxxxxxx
Is there a way that we can generate addresses which end in the desired way ?
For example : 1xxxxxxxxxxxxxNAME
If it is possible then whats the command line for windows?

I didn't understand the last one. Can you explain what do characters inside the brackets indicate ? [Aa] = A or a {2} two symbols, so here it can be AA, Aa, aA or aa 1{2} means two ones. $ must end with so in total the possible results are all addresses that end on one of the following strings AA11 Aa11 aA11 aa11 You could also do [0-9]{6,8}$ which would be 6, 7 or 8 numbers at the end, e.g. Pattern: [0-9]{6,8}$

HA most vote are either 100% or less than 10%
silly sock puppets you supposed to all vote for the same thing.
Equal oportunity sock puppeting? here we go CIYAM calling everyone stupid all day again.
The vote was called stupid and I agree with CIYAM. There will be nothing learned from the results because we cant know whether a single person voted 10 times. the votes are not cryptographically verified? O_o! Great, you are aware of the flaw, why defend the poll then? Its not like votes based on signed messages and btc balance are not implemented. |
