[ESHOP launched] Trezor: Bitcoin hardware wallet

[RoadStress]

Each password with any given seed will generate a completely new master public and private keys. Think of it as a completely new tree.

Now I'm a bit confused. I don't get it how master seed+password work. Can I recover coins with master seed if I forget the password?

No. If you use a password and forget it the coins are lost forever.

Hi Guys,

Is there a tool where I can flip a coin 256 times (or role a dice for example), then enter results + extra passphrase in and get 24 word + passphrase  seed out?
I've found few github projects, but all of them generate the seed for me from computer's RNG. Unfortunately my coding skills are insufficient to code this myself...

Also... I've been reading that entering seed in manually reduces entropy bits. Is this because computer can be compromised while entering a seed and because there is no direct way to enter seed into Trezor directly?

And... if the later is true... why there is no way to enter seed directly? ... after all Trezor has screen and buttons and only geeks would do it : )

Thanks!

Can I get my hands omn a metal one somehow?

Is everything OK with mytrezor.com?

Since this morning it is really buggy, one of my transactions didn't go through, it is just sitting there unconfirmed and it is not on a blockchain and my balance on the left side is not updating. It is stuck since last night.

I tried forgetting the device but the problems persist.

This is getting really weird, I cannot send any BTC from my trezor. I can receive but not send. I do get a txid like this,

https://blockchain.info/tx/5f2432dcf9c9ebed5624d3c020be14cae4079c4329e60dac5bc87e693cf63649

but it is impossible to see it on the blockchain. What is happening? Anyone else experiencing the same problem. I have 4 transaction stuck like this.

I am really worried, I did a trezor recovery this morning from the seed but this is still going on!

It appears as if your transaction was never broadcast to the bitcoin network. Install the new version of Electrum. It will work with your Trezor and works well. Just create a new hardware wallet and it will get the master public key from your Trezor and you will be good to go.

If there is some problem with the mytrezor.com website it is possible that the transaction maybe broadcast later so I would avoid double spending the coins for at least 12 hours to see if the transactions go through.

It worked, thanks. It is not a trezor problem it is a mytrezor.com problem. Is using electrum with trezor safe? I suppose that it works in a same way as mytrezor.com, private keys and trezor password are never exposed to the electrum, right?

You probaby shouldn't enter this on a computer.

Why not just print out the possible words, number them and select 24 of them by coin-flipping or using dice?

I don't know how safe they are to use though and I would only do this on an offline computer with a live cd.

Yes, it is completely safe. The Trezor just provides Electrum with the public master key to derive the receiving and change addresses. When you send bitcoin each input is sent to the Trezor for signing with the private key (which never leaves the Trezor) and then the signs the transaction. The complete and signed transaction is then broadcast to the bitcoin network by Electrum. In no way is your Trezor exposed any more than using MyTrezor.com. The seed is safe and never revealed in any way, unless you tell it to someone.

I lost you there... could you please elaborate? How would i integrate checksum?

Thanks! Exactly what i was looking for. I guess being offline on airgaped comp should be fine.

good point. I was a bit naive and thought any combination of words would be a valid passphrase. I'm not sure this is the case.

Although using a mnemonic not generated by the algorithm described in "Generating the mnemonic" section is possible, this is not advised and software must compute a checksum for the mnemonic sentence using a wordlist and issue a warning if it is invalid.

Not sure how trezor handles this.

I ~think~ as long as you stick to the wordlist you are fine. https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

There is no checksum in seed, any combination of words (of bip39 list) is just fine as long as they are truly random and not chosen by a human brain.

Thanks for all the useful info!

I think my brain is random enough.

No. If you use a password and forget it the coins are lost forever.

What if I disable the password and have only one PIN? If I forget the PIN can I recover the coins only with the master seed?
