Yes , Please is this the right command : pywallet.py --dumpwallet  or please give me a simple command thank you very much for your time  The command I use is this: python pywallet.py --dumpwallet > wallet.txt This writes it out to a text file called wallet.txt located in the folder you have the command prompt open to. If your wallet is encrypted: python pywallet.py --dumpwallet --passphrase=PASSPHRASE > wallet.txt where PASSPHRASE is your passphrase that you encrypted the wallet with. Again, it writes it to wallet.txt located in the folder you have the command prompt open to. |

It's been hours since I started the wallet and it was like 5 days ago and not it freezed at 39 Hours behind . I don't want to close it because I want it to finish sync right now , and if I close it it will start all over again when I run it once again later .
It shouldn't. It should pick up right where it left off. Anyone having this issue ? I thought it's my internet connection so I reboot the modem once again in case but nothing happens (it usually works) suggest me anything ASAP ty
When I hove my mouse on the ProgressBar it says :
"Catching up ...
Proceeced 365932 blocks of transaction history ."
How many peers do you have? |

hi
Please What "--dumpwallet" do in pywallet - i want i simple command to get my privat key using python only.
Thank you!
It returns the wallet in a human readable format. If it is unencrypted, you will find all of the addresses, including pregenerated ones, labeled and with their corresponding private keys. i can see my last transactions , but i cant see my private key please any more info sir ? Transactions aren't stored in the wallet.dat, at least, I don't see any in mine. If your wallet is unencrypted, you will see a lot of stuff like this (this is one for my testnet wallet "addr": "mmLRgxXCSaRrmoXSo2sgGe2CQmo4cavdKU",
"compressed": true,
"hexsec": "a7b36bd39f558ea03c415d2a522a0609caf2d014506fe9db921dc1064eb01ba3",
"private": "3081d30201010420a7b36bd39f558ea03c415d2a522a0609caf2d014506fe9db921dc1064eb01ba3a08185308182020101302c06072a8648ce3d0101022100fffffffffffffffffffffffffffffffffffffffffffffffffffffffefffffc2f300604010004010704210279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798022100fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141020101a12403220003072a91ff1ebcb4bff0c8368afcfc0a01eed33716311a7cee3dcd5b43c057b55f",
"pubkey": "03072a91ff1ebcb4bff0c8368afcfc0a01eed33716311a7cee3dcd5b43c057b55f",
"reserve": 1,
"sec": "cTCgz77r4BigUt4CVbW4MEWXTNJMm95caZX2TWc98icXsGTZUEss",
"secret": "a7b36bd39f558ea03c415d2a522a0609caf2d014506fe9db921dc1064eb01ba301" The part you care about is "sec" that is the key in Wallet Import Format. It should start with 5, K, or L. This one starts with c because it is testnet. If the wallet is encrypted, you should see a bunch of stuff like this "addr": "mgCepFFmwNiNSCGoGeZSG6U7eGRkzzwjWw",
"compressed": true,
"encrypted_privkey": "e53d309fad405b3c2f3aca08658466ec6f33132cde378bae20d3d8af37949b444e17981f1223158dbac624f5e4b77333",
"pubkey": "020188f460b3ba47dc0f4506e833140f672fd7e0e8a536458e33b39e8eeee6b933",
"reserve": 1 Obviously encrypted privkey is your private key encrypted. You will need to use the --passphrase option and set your passphrase. |

Im just trying to learn sir , also please tell me what info can i see if i used Notpad++ to open the wallet , thank you You cannot. All you will get is a bunch of garbled text. You need to use something like pywallet to get it into a human readable format. I have several wallet backups and they range in size from 400 KB, probably the first backup, to 4 MB which is one of the later images. I opened one up with notepad just to peak and as others have indicated you will see a bunch of random gibberish, at least nothing in human readable format.
I assume they are encrypted, probably sha, I am not sure how file encryption works but I don't think those will be able to be broken at all or by any asic. SHA is not an encryption, it is a hashing algorithm. The wallet uses AES encryption with a key derived from your password using SHA512. |

You need to escape each quote. Put a slash / before each quote.

I'm not promoting any particular coin. I'm asking what alt-coin out there isn't vulnerable to the inevitable 51% attack.
I'm a full supporter of bitcoin, but I will not ignore the fact there is a hole in the Bitcoin system which makes it imperfect.
The attack WILL happen.
First of all, EVERY COIN is vulnerable to a 51% attack, just like your password and cryptogrpahy are vulnerable to a brute force attack. There is nothing that can prevent one. However, the costs of performing a 51% attack are extremely high and it is difficult to pull off. The community will react and come up with a solution, which might just be get more people to mine thus reducing the attackers percent of the hash rate. Also, a 51% attack is not the end of Bitcoin. All the attacker can do is double spend his own coins, attempt to prevent people from spending, and attempt to prevent miners from mining. Even with 51% of the network, that doesn't mean the attacker suddenly has absolute power and full control. That just means that he has a higher probablility of finidng more blocks and could potentially create a longer valid fork of the block chain. The other 49% of the miners would still be finding about half of the blocks. In order to actually gain control of mining and adversely affect Bitcoin, the attacker would probably need somewhere upwards of 80 - 90% of the hash rate, which is much more expensive than just 51%.Whatever amount that is, it's peanuts. If all the major banks came together (Citigroup, JP Morgan Chase & Co, BoA, HSBC, Wells Fargo), they could have the attack done in a matter of 2 weeks. They could put together enough money to take full control over the blockchain with ease. I wouldn't be surprised if they already have the facilities built and just waiting for the perfect moment to shut Bitcoin down. The U.S. government..... I don't even have to explain. And if they did that, the banks and the government would all be bankrupt. They would have literally shut themselves down due to the costs of maintaining such an attack. The people wouldn't be happy and whoever was in charge would be gone. |

again this crap, the money needed to set up a mining operation that could overwhelm 51% of the network at this stage would be best used with that same equipment to secure the network instead, and earn the normal reward from the mining activity
would be more feasible for chinese to do this, because they are already at roi stage
You don't understand, the 51% attack is to destroy the infrastructure of bitcoin in order to save the established banking system in the U.S. and worldwide. They will have to spend a ridiculous amount of taxpayer money. In democratic systems like the U.S. and other countries, those people who came up with that plan will be voted out of office very quickly since they would be spending the taxpayer money on something that has no return at all, attempting to destroy Bitcoin. There is no gain for the populace and those politicians will be replaced by people who are either neutral or pro-Bitcoin. Even if the attack was to destroy the infrastructure, as soon as it stops, the network will rebound. Those that have faith in Bitcoin will find a solution. Probably something like a block or small code change that drops the difficulty back to a usable level by the rest of the miners. After a few months, Bitcoin will be back on track. |

light client ? please explaine more .
SPV Clients like MultiBit or Electrum don't need to download the whole blockchain. You can use a tool like pywallet to extract the private keys and import them into another wallet. Or you can import it into blockchain.info and send the Bitcoin from there to another wallet. |

Dude, watch this: https://www.youtube.com/watch?v=ncPyMUfNyVMYou don't understand how Bitcoin and the blockchain works. The amount of computational power you would need to severely disrupt the network at this point is just ridiculous, and they would lose tons of money trying to do so. They would gain way much more money by being good actors. Learn how the consensus algorithm works before you drop your next FUD thread. Attack or not, bitcoin will be replaced. Lack of development. Are you nuts? There is tons of development happening. Just look at the Mailing list. Instead of rushing things out, the developers are going through it slowly and carefully because new stuff in Bitcoin can adversely affect a lot of stuff, so they need to be careful. There is plenty of development and lots of testing and careful consideration before something is ready to be released. |

All valid points, than you all for your feedback.
How can I try and get new users of Bitcoin to try my wallet? What would you do?
First, get it approved on the Play Store. Then make it open source and contact the people at bitcoin.org and see if you can get it listed on their website. It will make you seem credible and let everyone else know that trusted people have looked at the code and determined that it is not malicious. Advertise it around the forum and give some people free Bitcoin to start with. Say like the first X users get Y Bitcoin free. |

It looks like they aren't making any money right now but will probably in the future. They are funded by Stage 1 Ventures,a venture capital group. I'm guessing that once enough people here about them they will come out with more stuff that you have to pay for so that they can make money.

Why do Chinese guys not speak English?
Why would they? It is China, they will speak CHINESE, the official language of the country. What's up with those face masks?
Those miners look very dusty and that could kick up a lot of dust that they don't want to breathe. Also China has a major pollution problem. And why do they love squatting so much?
I don't see them squatting that much except to pick things up. It is better to squat to pick things up so you don't through out your back. Legs are stronger than the back. Must be their third world toilet system. Does China use toilet paper?
YES! Of course they do. They also have running water toilets just like in America or Europe. I think this video is absolutely tragic. The investors who put up the money for this mine are a full two years too late. Must have been one hell of a con job / sales pitch to get them to write the check. The difficulty is so high that they have to spend a ton to have a chance at making anything, and with the Chinese quality electrical system in this mine, that place is going to go up in flames before they get anywhere near making a profit. Watch and see.
They already ROI'd on the equipment so this is pretty much pure profit now. If you look at the thread about this that Eric Mu started to show the mine, you will see that they are improving their electrical and safety stuff with advice from members here. They also have new equipment. I find your comments quite offensive and insensitive to other peoples and cultures. |

I am and will continue to read this, but right off the bat, I am seeing a few issues with this paper. First, it says that partial proof of works are submitted by miners to the pool. This is incorrect. Miners submit blocks to pools that are below the pool target, which has a lower difficulty than the network. These would all be valid blocks if the network difficulty were that low. It also says that a miner which withholds blocks submits a block that the block would be rejected, which is also false. The pool would accept the block provided that it is valid.
I will read more and see what else I find.

I second this. Instead of converting Bitcoin to fiat which may be useless, I would most certainly use it to buy stuff priced in fiat yet still accepting Bitcoin like on newegg or dell. Turning that Bitcoin into a product would benefit me more than converting it to fiat which will either go to crap or sit somewhere and do nothing. There are still things though that will need to be bought with fiat but a quick small conversion can easily solve that problem.

So this is kind of like Ebay with Bitcoin right? Not really a middle man between the business and Bitcoin payments like processors such as BitPay do.
|
|

That seems like a good idea, but it would be rather hard to put into practice.
The Bitcoin could be stored in a multisig address which would require several people to sign the transaction. How would the signers and board be chosen to review the cases? Also, it is very hard to determine whether Bitcoin was stolen or not since people could fake them and try to scam the insurance to pay them.

100% positive it belongs to BitFinex.
Why would it belong to BitFinex...? I find no relation to all the micro-transactions going in day after day? Apparently the people behind the spam attack were sending the dust transactions to many publicly known addresses. One such is this one. Wiki Leaks and many others have also been receiving those transactions as well as known brainwallet ones. As for why, I don't know. |
