I think Rollin.io is painting each pixel of their signature making an illusions that looks like there's a background color on their signature, while it was actually colored pixels  That method might work but it will consume your time coloring each pixels But if that's what you want it' worth a try  Yes, they are using font size 2 blocks like these: ███████████ █████████████████ |

I know Tails Come With Electrum
But can you tell me how can i install electrum on any linux distro not just tails?
Because i have read electrum is not easy to install on linux so can you please suggest me how to install it?
Well electrum runs on python and I dont know of any distros that dont come with python. I just download the tar.gz[1] from the sources section, extract it[2], change into the newly created folder and run it with python electrum. If you do everything from terminal, the following steps should start electrum for you on any linux distro. You will need to copy the public key[3] from ThomasV into a file named thomasv.asc first though. mkdir electrum
cd electrum
###put thomasv.asc in this directory as well###
wget https://download.electrum.org/2.6.3/Electrum-2.6.3.tar.gz https://download.electrum.org/2.6.3/Electrum-2.6.3.tar.gz.asc
gpg2 --import thomasv.asc
gpg2 --verify Electrum-2.6.3.tar.gz.asc ## should return 'correct signature'
tar -xvzf Electrum-2.6.3.tar.gz
cd Electrum-2.6.3
python electrum
If you already have electrum on your system it will open the last wallet. If not it will promt you to create a new one. [1] https://electrum.org/#download[2] tar -xvzf filename [3] https://pgp.mit.edu/pks/lookup?op=get&search=0x2BD5824B7F9470E6 |

Hey guys, was trying to make my own signature but I have a problem.
You can see my signature below. The background should be black, but it doesn't shows. I was inspired on some signature campaigns and was watching about their bbcode. But I can't make a black background. Can someone pls help me with this little problem? Thanks
use blah blah for where you want the background color to be.
if you are Hero or higher... the OP is Sr. though.So this works only at hero or higher? That should be my problem  Yep Perhaps the allowed signature styling should change with activity score / membergroup. Like:
- Newbie: No styling (including links) allowed. Max 40 characters.
- Jr. Member: Links allowed. Max 100 characters.
- Member: Unlimited length.
- Full: Color allowed.
- Sr. Member: Size allowed
- Hero: Background color allowed
Then newbies will be less effective advertisers, which would hopefully significantly reduce the incentive for low-content posts. And when people become capable of effectively advertising through their signatures, they'll have invested a lot of time into their accounts, and they won't risk being banned by spamming.

I bought this account for the cheap without a signed message, I should of known it was stolen
I am willing to give the account back
I havent been on this account so i didnt notice this thread, Shorena or any trusted member can pm me and I will send them the new password
Cant you transfer the account directly? I can hold the account, but I dont see a reason why I should. Unless you are asking for a (partial) refund here. |

You can do that by yourself easily. Press "All" instead of viewing each page one by one (or add ";all" to the end of any thread link), and then CTRL+F. Type in whoever you're suspicious about and presto!
This only works if the thread is (equal to, or) shorter than 25 pages on this forum. Therefore, this won't work in bigger threads. Additionally, it would be better if a separate page opened with the desired results (so that one does not have to open a single page with thousands of replies). On longer threads I use "print" instead. It includes quotes though. Another way would be to do a search for posts by the user in question, use (part of) the threads topic as search criteria and check "Search in topic subjects only". |

-dbcache=<n> Set database cache size in megabytes (4 to 1024, default: 100)
So I have a 4 GB system, default is 100.. why is it so low? and why is 1024 the max? There are systems with 64GB of ram out there but limit is 1024 to be used by the program?
Anyway, where should I raise this to, considering I have 4GB?
I put it on 4096 to sync, because it significantly reduces sync times (~8.5 hours on 2 cores, mechanical disk). Once Im done I remove the line from the bitcoin.conf though. What it does is reduce how often core needs to write changes to the database to disk. Im not sure if 1024 is still the max. A higher cache provides next to no benefits under normal circumstances AFAIK. Well it takes ages to shut down though, but I dont see that as a benefit. |

Say i put ubuntu on usb and boot from it and now generate 1 paper wallet using bitaddress.org gitup file locally and then instead of printing this i ssved it as pdf and then after booting back to windows i put this pdf in .rar file with secure password protection and save this file in mutliple places.Then even if i use the internet i won't be at risk right?
Why not encrypt it on your throw away USB stick OS? If you move the PDF unencrypted to a different machine it make no sense to set up the USB stick OS in the first place as it offers you no additional security. is bitaddress.org paper wallet generation really random?
Yes, even on low entropy systems (e.g. new OS on SSD/USB stick). The mouse movements required at the start provide enough entropy to make the key generation random. and last question if i have say 7 bitcoins on this digitally stored paper wallet and i want to spend 2 bitcoins from it and want to have 5 bitcoins in it.Can i do so?
Yes, if you are careful. More below. because i have read somewhere that we need to sweep the paper wallet and why's that?Can't i just spend directly the amount i wish to spend?
P.S i don't want to print a paper wallet because i am too paranoid i may lose the paper or damage it
The "problem" with spending paper wallet funds are the software you use to do so. If you have 7 bitcoins received to a paperwallet, these 7 bitcoins are considered one or more inputs you can spend. Lets assume for simplicity you have only one input. You can think of it like a 7BTC bill or a lump of gold (I will go with the gold for this example). If you want to spend the 7 BTC lump you have to melt it down and create pieces of lesser value. Different wallets do this differently. Some would send the 5 BTC you want to keep (assuming no fee for simplicity) back to the address you previously had the 7 BTC on. Some would create an entirely new address for this. Its best that you prepare another paperwallet and manually send the lump you want to keep to it. E.g. you have 7 BTC and want to send 2 BTC to Alice while keeping the remaining 5 BTC. You use the funds from your old paper wallet to create a TX that sends 2 BTC to 1ALICEvanity and 4.9998 BTC to 1myNEWpaperWALLET the remaining 0.0002 is used as fee. Ok i have read that mycellium bitcoin wallet alows spending from cold storage so if use it to spend 2 bitcoins from paper wallet will the remaining 5 btc goes back to my paper wallet? AFAIK not, the way I understand what mycelium does in this case is that it sends the 5 BTC to a newly generated change address that is part of your mycelium wallet. I also think its a bad idea to reuse a paper wallet. The whole idea is that you have an offline key, one that was never on an online system and thus can not be affected by a virus. This is longer the case once you use the paper wallet at least once. Hence the suggestion to create a new one. On the other hand you dont store it on paper either, so maybe something like Tails[1] is better? and why the new 5 btc that comes back to the same address do not show as new transaction?
Because its the same transaction. A transaction can send coins to many addresses at once. And yes how do i encrypt the pdf on throw away ubuntu system that i used to create the wallet?
PGP should be available by default or you could use something like e.g. VeraCrypt (which is based on the famous TrueCrypt) sinec you need to get some software on the stick from the internet anyway. And what if i use Electrum instead of bitaddress.org to generate the address as i think electum will be much safer.right?
I dont think it matters much. You might want to use electrum from a live OS like Tails though since this would solve your "change" problem. Instead of a private key you would secure the seed and restore the wallet from that every time you want to spend some coins. The seed would (unlike a private key) cover all future change addresses and can offer you different addresses as well. Electrum is also preinstalled on tails, so you would not need to install any software. Tails does not come with VeraCrypt yet[2], but they have different means to help you encrypt data.

This is not accurate ! A newbie account with just 2 posts is marked 0.002 BTC . Its too high for it. That's the payout of signature campaign for posting about 15 posts by a Member account. I think you should edit the algorithm.
With 2 posts you can have a max of 2 activity: 0.0003 BTC/activity * 2 = 0.0006 Lets further assume the posts where of "excellent quality" 0.0006 * 1.05 = 0.00063 I dont know how you get to 0.002, but maybe you can help us find out whats wrong by sharing either the user ID of the account in question or the token. |

Thanks guys. Found my answers and now I'm practising!
Thanks for reopening the thread. Id just like to share a different view. It is probably not applicable for a lending or marketplace thread, but for other sections. If you lock a thread you remove the chance that someone can add a point to a discussion or ask a follow up question. As often xkcd[1] comes to mind:  [1] https://xkcd.com/979/ |

Bump, also: should you win the auction you are free to resell the signature for profit.

hi, the icon is in green and i had tried to change manually the server (all of them). when i load the transaction with the adress it says "transaction unrelated to your wallet" . Im 100% sure of the adresses i gave. the persons have confirmed me that point.
The problem ocurred before i tried to update or restore the wallet with the seed.
It was simple i gave the adress from my electrum wallet , the guy said its sent here is the blockchain but still nothing on my wallet.
A bug ? others adresses generated?
Did you change the gap limit for the wallet in question? |

So, I've got a few bitcoin daemons running on multiple OS. Things typically go smoothly; however, every now and then one of them will simply stop getting new blocks. Even though it is fully connected to the network and is responding to queries fine, it's just not caught up. I could understand if it were a few seconds back because of block propagation, but sometimes it's many minutes and multiple blocks behind.
The process itself isn't frozen, the debug log shows nothing amiss - typical advertise local messages, connections coming in, etc. Yes, the proper ports are opened. The CPU isn't spiked. There's plenty of free RAM. It's like it just decides to forget about the fact that it's supposed to get new blocks. If I restart the process, it immediately gets the blocks it was behind.
Any thoughts?
Do your peers have the blocks you dont? |

So i installed Electrum on my very old offline PC which will Never be connected to the internet.I saved the seed and got bunch of address and private keys.I exported master public keys and imported these public keys on my Laptop that is connected to internet.Now it's watch only addresses on my laptop which is connected to the internet.
I can create a transaction on my online laptop and save it and transfer it to my old offline PC and then sign it and transfer it back to broadcast on my online Laptop.Now is this the safest cold storage? and will my private key leak after transfering signed transaction back to online Laptop?
I use a similar setup for my offline wallet. There are probably safer ways, but I think its safe enough for the amount most people have. You still have to take care of your online system though as CIYAM pointed out, the USB sticks may transfer malware to the offline system. And Electrum generated 10 address with private keys on offline PC which is Not connected to internet.What are the chances that any 1 of the address can again by generated by some other Wallet?
The chance that someone else has the same address is you is 1 in 2 160 or 1 in 1461501637330902918203684832716283019655932542976. And one last question,Just in case my old PC goes out of bussiness and Does not start on some day then how can i recover my bitcoins and even that possible to recover in such case?can i take backup?
Yes, but you dont have to as long as you have the seed. I will appreciate some experienced bitcoin geak to please come and answer these. This setup is very secure in terms of viruses or online attacks, but less secure in terms of physical attacks. The laptop can be stolen, so I suggest you encrypt the disk and/or set a password for the offline wallet. Its also not very convenient for regular payments, thus its probably best if you keep one or more hot wallets for smaller amounts and refill from the cold wallet as needed. Thank You Can you please tell me or suggest me how to set a recommended fees in electrum when sending bitcoins? I usually go with the cointape[1] suggestion or ask my bitcoin core client ( estimatefee 2) and roughly estimate the size. The ~225 byte on cointape are usually correct unless you have a larger number of inputs. If you go to your addresses tab in electrum and right click an address you can select "send from" this allows you to select which inputs to use and is similar to coin control by bitcoin core/classic. Is there any way electrum can suggest me the recommended fees? How to calculate the size of the actual transaction before sending?
Electrum has several options for fees under Tools -> Preferences -> Transactions. I tend to set the fee myself though. I usually pay a higher than needed fee for trades or to release funds from escrow, because I dont want people to wait just because of a few satoshi. When I send funds to myself I usually pay a lower fee, because I dont mind if I have to wait. On how to calculate the size I suggest reading these[2] stack exchange answers. You are most likely using compressed keys. [1] https://bitcoinfees.21.co/[2] http://bitcoin.stackexchange.com/questions/1195/how-to-calculate-transaction-size-before-sending |

I never took this seriously honestly (Paypal or any other payment method) but do they allow trading Bitcoin?
No. or it's against their TOS.
Yes, they have a clause about digital items and currencies IIRC. I'm not sure how they are supposed to know if you are trading bitcoin or not , but I'd like to know if I can do it according to their terms or not .
also I want to know anyone of you know when the 21 days hold thing disappears from our accounts ? that should make bitcoin trading easier. (or anything else)
You can do the trade, you just dont get any help if the paypal payment is reversed. Not sure what you are refering to with the "21 days hold thing", but its been years since I used PP. Maybe someone else can chime in. Keep in mind that PP is reversible for up to 180 days. This includes gifts and every fancy payment comment people come up with. |

sie war syncron.
transaktion wurde nach -salvagewallet dann mitten in der nach ausgeführt
Macht keinen Sinn, salvagewallet versucht eine beschädigte wallet.dat wiederherzustellen. ich hatte die fehlermeldung die ungefähr so lautet die transaktion konnte nicht durchgeführt werden da sie bereits ausgegeben wurden und die anzeige nicht aktuell ist. mögliche ursache das ich eine kopie der wallet.dat benutze und sie bereits ausgegeben wurden. oder sowas ähnliches. Da ich keine kopie der wallet.dat benutze hatte ich zu schnell weggeklickt. hmmm, komisch. Naja, wenn jetzt alles wieder da ist, ist ja alles gut. |
