Reine Panikmache, natürlich legt keiner seine wallet.dat unverschlüsselt auf nem Webserver ab. Ich würde mal behaupten die meisten haben nicht mal nen Werbserver auf ihrem privaten Rechner laufen. These are failed http requests ...

Ich dachte irgendwie dass der Trezor mehr Sicherheit bietet. Aber was er macht ist einfach nur die Keys sicher aufbewahren.
Exakt. Wie Lincoln6Echo geschrieben hat, ist das Gerät vl. auch eher für PC-Laien gedacht. Es ist halt eine sehr simple offline wallet. Man kann dafür auch nen alten Laptop nehmen, macht von der Sicherheit her kaum einen unterschied. |

It has been almost a week now that I've been synchronizing a Bitcoin Core node with the network. I'm still 24 weeks behind. Yesterday I was 27 weeks behind. I suspect that it will probably be another week before the node has caught up.
-snip-
Who is going to run a node if it takes a month to synchronize?
It only recently took me 8 hours to fully sync. What system are you using? (most interesting are: OS (32 or 64 bit), CPU, Internet speed and disk type (SSD or mechanical disk (raid?)) |

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. |

Do you think anyone who feel sad for humanity and innocent lives is terrorist?
Dont be judgemental friend let people speak their mind
Dude, You are blind on bot eyes and something working not in the head. He mention exactly "Occupied Territories of Caliphate of Baghdad" by Crusades. This dude use the word "Mujaheddin" to terroristic activity and murder of policemens, in direct contrast with Quran. ISIS take the responsability for this explosion, and this recruiter for the salafi jihad call them "freedome fighters". He have writed here enough to be in prison in Russian Federation as extremist.I see, for a NATO country as Turkey calling ISIS international actions as "liberation from invasors" and "freedome fighters", recruiting in salafi jihad, rappresent no crime. Russia is quick in that regard, yes. It does not mean they are violating the forums rules though. |

@knightdk could it be that you see higher memory use becasue you use test builds with additional logging?
Probably not. The test builds do not have additional logging although sometimes they can have bugs which could have memory leaks. I probably see higher memory usage because I also have txindex enabled but that seems to mostly effect my disk usage. I have enabled txindex now as well, but it still does not use a lot of memory. htop reports ~1.1 G, same as free (w/o cache). -snip-
I find it odd that you see free memory on your nodes and that your 6GB one does not top 3GB... A few minutes after syncing are enough for me to see all my RAM being consumed regardless of the amount and bitcoind version.
Are you sure you are not looking at cached memory values? The entire memory is used all the time anyway, its just not used all at once. Its a very minimalistic setup though. Its just core, the web server and some scripts in the background that update the pictures and collect the data. |

Please PM me if you can give me your old and not used private key.
How old exactly do they have to be? Maybe like...pre 2014?  You smell someone digging for clams as well, eh? |

For a school research project I need several bitcoin addresses (with privkey) which had transactions on it in past.
I do not need any bitcoins on it, but the address should exists in the blockchain with a couple transactions on it.
Please PM me if you can give me your old and not used private key.
Thank you.
For what exactly do you need them? |

you might just want to report posts you have issues with
I report a jihadist ideology poster, not a post. Thats not against the rules though. |

If I create a thread, can I post something like "all posts after this post must follow this new local rule" and will that be enforced by mods as local rules in the Op are?
If you mean, if you post in the OP "All posts must be in this format" or "No posts about this topic will be allowed in this thread" Then yes, that is a local rule to the thread, and people violating that rule will have their posts removed if reported. If you mean to make it complicated and say "all posts after post #3 must be *insert rule*" that is probably a little unnecessary. I mean like the thread already has several posts already and I notice a trend in those posts that I don't like, e.g. they are posting about a related topic that I don't want the discussion to be about. Then I post a new post (e.g. post #34) with something like "all posts after this one cannot be about X topic". AFAIK you have to lock and restart the thread. |

My bad too ! Too much chrome tab around here ... Yes, indeed I mean this link. So the final signature is this one : -----BEGIN BITCOIN SIGNED MESSAGE-----
This is the real person behind onepix pseudo from bitcointalk.org and today is 2016.03.28.
My account onepix is hacked and don't have any control on it.
Hacker started to use my account on January 23, 2016, 03:28:31 AM.
I had control on my account before this date and I posted my DigiByte public key on January 16, 2014, 04:50:48 PM.
I never edited the post, the topic is locked and you can find it here https://bitcointalk.org/index.php?topic=412585.msg4548268#msg4548268.

I don't find an online signed message verifier too, which mean basically that someone who want to verify it need to do it via DigiByte Wallet here http://www.digibyte.co/choose_walletIn other word, that force people to do "boring" actions in order to help me. Well, I hope people are in a good mood haha message verified -> https://i.imgur.com/kUSlTv4.png |

Hi to my surprise i only see my tx on blockchain.info. Others don't just find my tx  and when i look by my address i see my original address with full bitcoins. If i resend this transaction with high fees then it will be confirmed,right? and can i send it to the same address that i sent earlier to? and what is the worst that can happen,can i even lose my bitcoins by doing all this  yes if you resend a transaction with same inputs with higher fees it will be confirmed !!! only !!! if a large portion of the network has forgotten about the previous transaction. Wait at the very least 24 hours after you issued the first TX. If a large part of the network still remembers your 1st TX, the nodes will refuse to relay the 2nd TX. and the old transaction will disappear from all nodes eventually. you can send it to the same address.
as I've said before the worst that can happen when you're trying to double spend is that nothing will happen because the transaction gets rejected. you can try again in that case. you won't lose your coins.
Correct, you can never lose your coins. Worst case is that you cant use them for some time. I tried broadcasting a new tx that i signed but unfortunately it did not go through any of the online service i tried.I always get error.What does it mean? Anyways,I have pm'd you the tx please check and reply me through pm I replied, was it a double spend attempt? I think its a bit early for that. |

Same as version 1, it makes it simpler. Version 1 addresses are just a specific script, while pay to script hash addresses can be anything possible with bitcoin. SegWit is also just a specific script where the signature is elsewhere.
I see, so the version 3, 3 is not version 3. will just phase out slowly the addresses, but I hope support for v1 will remain forever, in the protocol and in electrum, since most people store their money in cold storage.
Folks who have 5000+ BTC would probably not like to change their addresses often, so at least 20-30 year support for v1 would be good.
Version 1 address will not become invalid with SegWit, they will just require more block space and thus it will be more expensive (in terms of fee) to spend coins received on them. |

Its called change. When you receive 1 BTC in a single transaction you have to spend it entirely. Kind of like a 1 BTC bill. It can also be a 0.12345678 btc bill. If you want to spend 0.25 BTC of your 1 BTC bill you get 0.75 BTC as change (no fee for simplicity). Good wallets use a new address to receive the change. The TX you provided however was created by blockchain.info which tends to reuse the same address, thus the change is send "back" to the address the initial bill was recieved on. Good wallets use a new address which is not backed up with your normal wallet to receive the change there, fixed it for you A separate backup for every time a change address is created does not sound like a good wallet to me. Mabye I missunderstood your point? |

Whats your point? If the topic already exists or you think it otherwise violates a rule use the link to report it to a mod. |

I cant answer the electrum specific questions, but SegWit will introduce a new address type. You can keep using the version 1 addresses that are common now (starting with a 1) and thus every old software will still be able to receive and send coins. They can not pay to a new SegWit address however.
You mean 1 and 3, because 3 is for the multisig wallets. 1 is for version 1 addresses (pay to pubkey hash), 3 is for pay to script hash. A subset of pay to script hash is multi sig. So the new address type will be a 3rd type? What will be the purpose of the new address type?
Same as version 1, it makes it simpler. Version 1 addresses are just a specific script, while pay to script hash addresses can be anything possible with bitcoin. SegWit is also just a specific script where the signature is elsewhere. |
