1101  Bitcoin / Wallet software / Re: [ANN] breadwallet, first bitcoin network client for iOS, first BIP32 SPV client on: February 23, 2015, 10:46:00 PM
No.

I tried to use my MyCelium passphrase on breadwallet and, although the words worked, the balance was Zero. 
So, it would appear the checksum is valid on the phrase, but appears that bread has a diff offset or something.
This post doesn't answer why, but answers your question in that you can't simply use the phrase from one wallet to another for access to the same addresses.
1102  Bitcoin / Mycelium / MyCelium -Keys issue with regards to BIP39/44 and differences of iOS and Android on: February 23, 2015, 10:26:57 PM
Mycelium on Android differs from iOS / Master keys / Generating addresses

*Why does Mycelium display different master keys on the Android than the iOS version*
(And how to generate the same addresses from both.)

Mycelium 2.2.0 - Android
Mycelium 1.0.1 - iOS  (I will not go into the issues/bugs with the iOS version as it deeply needs to be updated - I have done a lot of testing.)
Using a random master seed generated and on each device works and the associated balances match (unlike breadwallet (another topic)).

Export a master public key for use in ecommerce or simply knowing the future addresses. 
To generate the addresses from the master key, you can:

Go to:  www.evilbs.com/bip39   or   https://dcpos.github.io/bip39/    or download and run offline (recommended).
The file/website keys shown matches iOS version of MyCelium, but not the Android version of the software.

iOS.  Install, make a new wallet.  You then have your master seed.  Since this is just for testing, I got:   
orange hurt leisure rely name multiply pond crawl canoe story only bird

Plug that into the bip39 converter (site or offline).
Click on 'Mycelium wallet' (or BIP44 - same thing) which simply sets to:  m/44'/0'/0'/0
bip 44 and 0's for point/wallet, etc
(I go to BIP32 and input m/44'/0'/0'/0  as this allows for testing/changing the numbers (not greyed out))

Great, this produces a mpubkey for the first wallet of: 
xpub6FJdwT45KSFs3fAhDGwzY6jrMqP5FETMkR3r9wikit2UoYLRUb625rcGUJzgQtKpNrhhi3tpRaC Ubab9tXqK9KqwnTesGQs4UTKHzcXkP4x
It matches the iPhone, and the 1st receiving address of: 14Brr4TQpx4a7WvpN52a7S3mZs9nNfCrLs  all good.

Now, as for Android, although my 1st receiving address is: 14Brr4TQpx4a7WvpN52a7S3mZs9nNfCrLs, the mpubkey
is different
Andoid:
xpub6DW3ui9w59vVVLtdCtNTrxdLNp9WVCppDhKdnyWDpkUC5ZtfMm1evZKyJte7GuSj9AncPh5kmgi 5wCk1s3yAGjQ1vNi1QyxaevXiULhX11a

When getting a mpubkey, you get a different one from iOS than Android for the same master seed; however,
both devices generate the same receiving addresses - The first being: 14Brr4TQpx4a7WvpN52a7S3mZs9nNfCrLs.   
I wanted to know why....

So, I went to any of the bip39 websites to see (after putting in the master seed and selecting Mycelium wallet....

The Derivation path on Android (to see current and future HD wallet addresses) is:
m/44'/0'/0'/0

Side Note:
(if you select bip32 (or custom and put in m/44'/0'/0'/0 )  it is the same thing.  Do this to see future receiving addresses)
and when creating another HD Account, the next is:
m/44'/0'/1'/0    and so on.

Everything the site shows matches the iOS version of Mycelium.  This does NOT work for the Android version since the
mpubkey is diff on the site than what Android shows you. 
So, why does the generated bitcoin addresses match if using different pub keys?

I decided to test with pycoin....

Using iOS mpubkey, for pycoin, you can generate the first 5 addresses using:
ku mpubkey -a -s0-4

0   14Brr4TQpx4a7WvpN52a7S3mZs9nNfCrLs   
1   1f26ma1LitK2Cv1aWRcdPQC7zBeyp5WWh   
2   1F5K9q3JnxZnRbSqoabU6P427rnbDTTyTG   
3   1CaBPyF78q17yo7ZjzJDY7kJfgEaEzaTpS   
4   1HqSjEyLj8LgEL7p3sisTvfvAXpfmnzUqf

Great, so everything matches and works on the iPhone


On Android, you get a different mpubkey; however, the address generation is the same IF you change the Deprivation path.
So, for pycoin, you can generate the first 5 addresses using
ku mpubkey -a -s0/0-4
0   14Brr4TQpx4a7WvpN52a7S3mZs9nNfCrLs   
1   1f26ma1LitK2Cv1aWRcdPQC7zBeyp5WWh   
2   1F5K9q3JnxZnRbSqoabU6P427rnbDTTyTG   
3   1CaBPyF78q17yo7ZjzJDY7kJfgEaEzaTpS   
4   1HqSjEyLj8LgEL7p3sisTvfvAXpfmnzUqf

Why a diff pubkey and why using -s0-4 vs -s0/0-4 to get the same matching receiving addresses?


Why is it that the website matches everything from iOS version of Mycelium, but not Android,
and why can't I duplicate keys list on the Android with the site?

1103  Other / Meta / Re: Mycelium getting its own sub-forum any time soon? on: February 23, 2015, 05:54:16 PM
I agree.

I have been playing around with mycelium for quite some time.  Can point out quarks and issues, etc that should be in a sub forum rather than simply posting in the thread as much would get lost in the shuffle as others post after me.

Got another issue which should have it's own thread in a sub.

Basically, I support MyCelium having it's own sub as well.

1111  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: February 15, 2015, 09:35:36 PM
Oh, and Bug 3.

During the upgrade to the new version, although my wallet was protected via backup on another device, most of the transactions disappeared from the accounts.

So, although my HD wallet is fine and the account balances are all correct (on the many HD wallet accounts), I lost all the transaction history on all accounts (except for a few prior transactions).  Not having the private keys is one thing, but now losing all the transaction history is bad as well.  Sad
1112  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: February 15, 2015, 07:13:40 PM
Something I consider a BUG and a BIG BUG (issue)....

Using mycelium for a long time now.

First small bug/issue is...
I decided to backup my device to another in case I lose one (both being password protected, etc).
Install mycellium on the second device, went to restore my HD wallet by using the seed restore.  All fine, except that I had 0 coins, and lost several 'accounts'.
I started to freak out.  Resync and still none of the other accounts appeared.  Double checked my 1st device to see everything was fine.  Yeah.
So, on the second device, I hit add key, then HD account.  The next account was recreated from my first device.  Resync, everything fine.
Basically, I had to hit add key, add HD account several times to get all the accounts back (while waiting for a sync each time).
I believe the "Restore" feature should automatically go through and find all accounts (and sync).

Second big bug...
I decided to make a backup (for various reasons).  Turns out my version was updated since the last time I did this, so....
Accounts, Menu, Backup.
It tells me that I can't backup unless I have a pin code set.   Great, so now I have to set a short 6 digit code on top of the giant ass password I have on my device.
Option?  No, it's a requirement in order to make a backup.  Geesh.   Ok, I set a pin.  All fine?, Nope.....

I go back to make a backup, and now it tells me this:
"Additional Masterseed Backup   
Sorry, an additional backup is currently not possible.   
Your PIN was recently changed.   
To increase the security of your funds, we prevent you (or anyone else) to export the master-seed shortly after setting a new PIN. 
You have to wait for at least 288 blocks (~2 days)."

Are you kidding me?   I can spend the coins, but I can't actually make a backup in case I lose my device.

PS. I still Love mycelium.  Smiley

Nice to see you're back to buying/selling.

Have I got a deal for you.  PM.
1114  Economy / Collectibles / Re: 2014 Casascius St. Petersburg Bowl Bitcoin Coin on: January 29, 2015, 05:29:45 PM
For those of you who already have had their coins shipped, roughly how long did it take for them to arrive (U.S. btw).  I received an order shipped email on Jan 20th, and have not received anything 9 days later.  I am getting unhappy with stryde, especially considering the $15 I was forced to pay for shipping, this thing should have been here next day.  Also it says UPS was the shipping method, but I can't find a tracking number anywhere, either in the email or under my account on their website.  Why on earth would they not send a tracking number with an order that was over $100?

Mine took 8 days, but they are on the East Coast while I am on the west Coast.
They shipped via UPS which is slower than USPS; however, it is WAY more secure and automatically insured.

You were not forced to pay $15 in shipping.  You didn't even have to order it.  Sorry, it just kills me that people know UP FRONT what the cost is and complains about it after the fact.  Just consider it a $115 coin with free shipping.

I do agree that they should have emailed a tracking number.  They do need to change.  I didn't find out my tracking until I signed for the package.  Smiley

If you want a coin fast, just PM me.  I will sell for $100 + $6 shipping (paid via Bitcoin of course) via USPS Priority Mail.  Fair?   Smiley
1115  Economy / Auctions / Re: [AUCTION] 1 Casascius 2013 + 1 Titan BTC (1oz999Gold) on: January 29, 2015, 03:22:00 PM
If it went for 8 BTC it was still a pretty good deal to the buyer in my opinion, that's barely over Bitcoin + Gold spot prices at the moment.
Current Prices (from Amagi):  Gold: $1275 Oz.   Bitcoin: $222   
$1275 1 Oz. Gold / $222 = 5.74 BTC + 2 loaded Bitcoins = 7.74 BTC total spot value

So all in all, that was a steal on a Casascius premium and the premium for the low mintage Titan One Gold.


Well, since the auction ended while bitcoin was at $241 and Gold at $1281
I saw the spot on the coins at price:  5.135 + 2 = 7.135 (and premium)
At the actual time I made my bid, bitcoin was at $281 which means the value in coin was less than the auction ending price.

I was going to bid 7.5 ending, but since he went to 8btc, I gave up.

Congrats on the sale.  Next step is to make it complete.

Yup.  Price went beyond what I was willing to pay though.

Attention out there, there are already some fake profile pretending to be me -> https://bitcointalk.org/index.php?action=profile;u=421723

Well of course.  It wouldn't be a true sale/auction thread without a scammer (the same one) that is trying to scam everyone in all other threads.
1118  Economy / Collectibles / Re: 2014 Casascius St. Petersburg Bowl Bitcoin Coin on: January 26, 2015, 04:39:21 PM
You could call them and email them.

Their info is on the site.
1119  Economy / Auctions / Re: [AUCTION] 1 Casascius 2013 + 1 Titan BTC (1oz999Gold) on: January 26, 2015, 06:06:08 AM
I guess escrow would have to be accepted unless the seller would agree to ship to me first.

I up my bid to 6.25

Please update for payment options.

I offer:
5.9 for the Titan
1.1 for the Casascius (but need more info).

Don't you have this on another thread as well?
