i just dl wallet of version 2.5 and this is my first try on chancecoin..here are some questions and forgive me if my questions sound stupid for 72 pages in this thread will take too long time to read  1.500 internal error when try to open decentrelised exchange..is that normal? 2.since this is chancecoin wallet..why we need bitcoin for transaction fees? 3.how to encrypt the wallet? 4.my wallet address: 1GcTaYN6iG9Pa83LvUG4VKvXu6WskuV5Cw is this a bitcoin or chancecoin address? 5.feel free if someone kindness enought to send me some chancecoins to try out  well..seems no one willing to answer my questions and i really not a tech guy..i guess this is not the coin i'm looking for Sent you some CHA to try everything out! ty for your generous but i'm not sure if it is the wallet problem or not bc i didn`t receive anything yet. Is the wallet uptodate yet? (top right corner: 314,914/314,914) |

When can I trade NFD on bter again? Kind of frustrating...

It would be nice to set up Trezor in a way so that you can have at the same time:
1) one 'account' with no passphrase (for small money).
This could pop up in the web wallet immediatly without further interaction when you connect the Trezor.
2) one or more (hidden) accounts. These would be visible only if the correct passphrase is
(optionally) given.
Is this possible ?
http://doc.satoshilabs.com/trezor-user/advanced_settings.htmlThis is not answering his question. He would like to have accounts with different security levels. One with PIN only, and one with 1 password, maybe 1 with 2 passwords ect. |

However: should you make a mistake and have to enter re-do the whole process, the random words will be known to a keylogger, because trezor chooses different random words every time. So the words identical between the 2 restore-processes (1 failed, 1 succeeded) will be the seed words.
With a 12 word seed theres only 12! = 479,001,600 combinations. So better not "try again" after a failed restore from seed on the same machine if you have a short seed like that... or just just 24 word seed to be safe.
Definitely needs that offline recovery tool Or a 36 seed recovery. Another possibility would be that a certain TREZOR has hardware specific "random words" in the seed recovery. So even if you recover twice on the same trezor, the attacker wouldn't know what the wrong words were. |

hi I just sent and already sent private message to evengrow with my BTCD address !
the change is tip for you TwinWinNerD thank you!
cheers! btcD gonna be sent out to ya after I see twinwin's btc address confirm on blockchain.info I see it's confirmed and got a message by TwinWin! I send to the address you provided in the PM shortly @soma. im waiting for some confirms please be patient for a bit. please confirm here once the transaction arrived in your wallet with a confirm, thx! its ok, I can wait a bit. But make sure to send it  edit; evergrow sent me he has some issues with exchange withdrawal and it takes a bit longer. its ok but really hope he sends really soon. thanks so much TwinWinNerd! hey I'm really sorry about this, never happened before! really embarrasing! please excuse me soma; I sent 49.98 to you already (transaction id: 58e7c164d28d2bb69474d5c97cd67489e72ec55af80ed3688c18bd6a7f865d8e ) - the other 4.02 are coming as soon as possible, please confirm to twinwin once all is there! again sorry to both of you, soma and twinwin! its alright man, no worries. got the 49,98, waiting for the rest @TwinWinNerd: you can release 0.184926 BTC to evergreen already, I'm just waiting for the rest as he has issues obviously. or just wait until I confirm all 54 in total. either case I received 49,98 of it already I'd rather wait for the whole payment. There is no hurry right? |

Sorry, yes, you are right. I see now But i think if hacker knows exactly words in random order it's not fine Ok, i will use 24 words. I think 6.2044840173323943936 × 10^23 variants of brute force will be enough for me Very good decision. And I agree that the 12 word option should probably not be the default! |

Your math is off, it is not 2^X but X!
3! = 3x2x1 = 6 combinations
12! = 479001600
24! = 6.2044840173323943936 × 10^23
This number is incredible huge, but potentionally crackable!
Sorry, i don't understand your math 3! = 3x2x1 = 6 combinations ^^^^ Why? Please write other variants for my example. You say that there (in my example) should be 6 variants. Please add other two ones If you have 3 words that can be on each position, but can only be used once, the math to calculate the total amount of combinations is 3! aka 3x2x1 Proof: 1 2 3 1 3 2 2 1 3 2 3 1 3 1 2 3 2 1 That are all the possible combinations. 12! = 12x11x10x9x...x2x1 So you see, 24! would be an incredible amount of combinations you would not be able to crack very easily. |

Ok, i am hacker and the right seed (for easy example) is three word, but in dictionary 2048 words for one position (as trezor has): User entered: red green blue Hacker got:blue green red Ok, he run process and got only these variants (B, G, R): B G R G B R R G B B R G Here 2^2 variants (may be because 2^(3-1)) If hacker doesn't know he should make 2048^3 variants (may be 'red', may be 'cat' and so on). Now imagine it for 12 words and for 24 words May be there will be 2^11 variants for 12 words, not 2^12 as i wrote above. Ok, for 24 words we will get 2^23 = 8388608 combinations I think this combinations can be computed for 1-10 seconds. I think user will not have a time to send him bitcoins to other. Ok, wallet32 Android application is BIP32 wallet. But if you use hardware device with private keys only in this device it will be very strange to setup seed at Android device for sending all bitcoins But this hack will be made for one second if hacker will sniff 12 or 24 words. Your math is off, it is not 2^X but X! 3! = 3x2x1 = 6 combinations 12! = 479001600 24! = 6.2044840173323943936 × 10^23 This number is incredible huge, but potentionally crackable! |

thank you guys! please give me a little time to send. I'll post once done ok?
hi sure no problem! as soon as I receive the 0.2 BTC from twinwinnerd I'll send out your BTCD's immediately. please tip him a bit! Correction: As soon as TwinWinNerD receives the BTC you need to send out the BTCD (after 1 confirmation~) Otherwise Escrow would be senseless for SOMAcoin. thats right and thats what I meant, sorry posted it wrong  ! somacoin did you send already? You can check here: https://blockchain.info/address/1NCaLcX6yZ379Rc24zMUicErUTi68N3cbahi I just sent and already sent private message to evengrow with my BTCD address ! the change is tip for you TwinWinNerD thank you! Received. Once SOMAcoin confirms that he got the BTCD, I will release escrow. |

Hi,
please wait
Ok, MyTrezor.com asks a user (i don't know - i didn't get my trezor, i wait) to enter 12 (by default) words. May be it ask by random order directed by trezor device. But words are entered in computer! Trojan already know exectly 12 words, may be order is randomized but there may be 2^12 variants to get right order of words. Am i right?
It's BIP32 wallet so hacker doesn't need to use a Trezor device - this process can be automated. 2^12 computations can be run in computer for seconds or less one second.
I don't talk about to guess seed. I am about to guess seed if hacker knows exectly 12 words of seed which he sniffed by trojan/faked mytrezor.com site and etc.
12 words is completely insecure if the attacker has infested your computer: Input: 12! Result: 479001600 combinations Just choose 24! and if you are paranoid then make a new account after recovery. |

@Pelover, well, the seed is entered in a random order. So even if the computer is compromised the attacked still needs to try 24! combinations before cracking your password. So you will have enough time to create a new account as BurtW said.
But if the new Trezor can use those words in random order, why couldn't the attacker do it too? Please read this: https://github.com/satoshilabs/docs/blob/master/trezor-user/recovery.rst' I have read it but cannot see the answer. The attack that worries the OP may be: hacker installs malicious browser/plugin in many computers and waits for one of the owners to start the recovery procedure. As the victim types the words, the malicious software sends them to the thief, and sends the wrong words to the victim's Trezor, so that his recovery will fail. Meanwhile the thief starts the legitimate recovery procedure with another Trezor, enters the words (garbled, with nulls and all), and gets access to the victim's wallet. (A basic problem of all security systems is that, whatever one must do to get access, someone else with the right information could do the same. Including biometrics. Thus, security always depends ultimately on preventing the bad guys from getting some critical information that the good guys have somewhere.) The TREZOR will ask you to enter the recovery seed in random order, and the order is only displayed on the trezor. You computer dosn't know what order is right. So even if the attacker has all words, it is pretty much useless. And the entered order is different everytime you are promted to enter it! |

SOMAcoin, here is the escrow address: 1NCaLcX6yZ379Rc24zMUicErUTi68N3cba
Once you send the 0.2 BTC there (+ tip if you want) you can PM evergrow the BTCD address.
