1  Bitcoin / Mycelium / I found a bug (March 21, 2018) on: March 21, 2018, 11:05:46 PM
I have two accounts in my Mycelium Android wallet.  They are labeled:

Bitcoin HD(1)  and   Other(1)

They are both HD wallets.

When I go to the Other(1) account and try to export the seed, it gives me the seed of the Bitcoin HD(1) account.
2  Other / Off-topic / provable destruction of information on: July 03, 2017, 01:48:56 PM
Is this possible?
an algorithm or process of some sort that can take a piece of entropy or information (e.g. a random number), use it (e.g. as a seed for something), then erase/destroy the source information, provably, so that it's gone and can't be retrieved.
Obviously no human can set eyes on the original number.

Edit:  this could be used for secret sharing, for example.  Pieces of the original number could be doled out to several parties who would then be able to reconstruct it.   And you could use combinatorics to create an m of n scheme.  Simple example:  divide the info into three pieces, N1 N2 and N3.  Give Alice N2 and N3.  Give Bob N1 and N3.  Give Charlie N1 and N2.  Then you have a two-of-three sharing scheme where two people out of the three are necessary and sufficient to reconstruct the source entropy.  This could be done with an arbitrarily large m of n sharing set.  You could set it to have four of seven people, or as many as you wish, with the right combinatorics.
The challenge here is how do you prove that the machine that divvied up the original number didn't keep it in memory.
3  Economy / Exchanges / Poloniex XMR deposits get stuck on: August 23, 2016, 02:38:22 AM
I have an XMR deposit that polo says has been at 7 confirmations for an hour now.  This has happened before.  So I opened another ticket. I have to open a ticket every time I deposit xmr.
I went on chat and all the mods can say is "the wallet is working perfectly"  wtf
The wallet isn't working, period.

5  Economy / Exchanges / Uphold took my money on: July 08, 2016, 03:57:25 AM
Yesterday I sent 1.5 BTC to my Uphold account.  It was a deposit to my USD "card".  Here is the address
1N5AGHtb9uKUJAN2Zq74qTpRV57gzKWgSo

Uphold uses single addresses and I can see all my previous Uphold transactions at that address in the blockchain explorer.  There's no mistaking it, the funds went to the correct address.  And as you can see, Uphold withdrew the 1.5 BTC from that address.

Uphold did not register this transaction and they didn't credit it to my account.  It appears nowhere on the transaction history.

Before this thing with the deposit happened, I had complained about something, and we engaged in a lengthy email exchange that went through people in more than one department.  I threatened to close my account.  I suspect that someone over there screwed with my account, tried to freeze it or something.  My account's still open, but something's seriously wrong.  And $958 dollars just disappeared into thin air.
6  Bitcoin / Development & Technical Discussion / Secret sharing on: July 05, 2016, 02:08:04 PM
Several people want to fund a bitcoin address using an m-of-n secret sharing scheme (shamir's secret sharing, for example).
Question 1
In order to get the address to send funds to, someone has to generate the private key first, and then get the address from the private key, is this true?
Question 2
So how do you enforce a no-peeking rule -- is there a way to prove that the person who owned the computer that generated the address from the private key didn't cheat and copy the private key?

8  Economy / Exchanges / Poloniex xmr withdrawal 0 mixin? on: March 23, 2016, 01:59:13 AM
On my last xmr withdrawal from polo, I saw that the mixin was 0.  What's up with that, I thought the protocol was enforcing mixin 3 by now.
9  Other / Off-topic / opera browser for linux on: March 17, 2016, 07:01:18 PM
I installed opera browser under ubuntu.  The browser will connect to some url's, and not to others.  When it doesn't connect, I get this error message:

SSL connection error

Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.

How would you fix this, is there some way to update opera browser so it has the correct certificates?

When I ran apt-get update, I got this

W: GPG error: http://deb.opera.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 63F7D4AFF6D61D45

I remember when I installed opera, a dialog box came up with some permissions or settings of some sort, and I changed one of them.  It had something to do with allowing something unauthorized, I think... maybe because the opera download doesn't come from the standard repos.  So now it won't update opera.  Sorry about being so vague.  If anybody can help getting this fixed, I would appreciate it.

11  Economy / Exchanges / Poloniex deposit not credited to account on: January 30, 2016, 05:21:01 PM
I have a ticket open with poloniex about this.  Their first response was, the deposit went through.
OK, it shows up in deposit history.
It has not been credited to my balance, however.
I asked again, on the same ticket, what happened?
No response.
Poloniex, get it together.  This is not good.
12  Economy / Exchanges / why the ddos attack on Coinbase? on: January 16, 2016, 02:26:59 AM
Early this morning the Coinbase exchange went down and stayed down for hours.  It was ddos.
What motivated the attackers, does it have something to do with the block size conflict?
13  Economy / Exchanges / coinbase exchange down, Jan 15 on: January 15, 2016, 03:32:08 PM
The coinbase exchange has been down for many hours now, following the sudden price drop.  They can't handle fast market movements.  I suspect the coinbase people took the exchange down on purpose.
14  Economy / Exchanges / Coinbase does not have email support on: December 12, 2015, 02:30:48 PM
I can't get money out of my Coinbase account.  The dollar wallet doesn't work.  I sent USD from the exchange to my dollar wallet, then went to Coinbase.com and looked for it.  There is no usd wallet.
I tried to find a way to contact Coinbase.  I looked everywhere, and I can't find an email link or any kind of support at Coinbase.com.  There's a discussion forum.  I posted there.  Nobody answered.
What can I do now?  I'd like to rip those people to pieces.
15  Bitcoin / Bitcoin Technical Support / Why does a high-priority tx get delayed? on: December 12, 2015, 03:26:03 AM
I just sent a tx and the first confirmation took an hour.

d75f3a16f84351a7cb23e24c0b082b8acb5ce4bc33f28fbe5a77a738842020bb

Blockchain.info said the transaction was high priority, supposed to confirm "very soon."
Is the network overloaded right now?  Or do some random transactions sometimes just take way too long for no particular reason?
16  Economy / Web Wallets / Omniwallet.org webpage doesn't load on: November 12, 2015, 10:32:27 AM
Often omniwallet.org won't open in the browser.  
Like today, no matter what browser I use, http://HTTPS://www.omniwallet.org just displays this single line of text in tiny gray type in the middle of the screen:

Omniwallet™ is a cryptocurrency web wallet that combines security, usability and meta-currency support.

There's no way to bring up the wallet.  
A couple of weeks ago, when the website was working, I opened a wallet.  I have a wallet ID.  But there's no way to go to the website to use my wallet.  The DNS resolves, but takes you to a dead screen with the text I pasted above.

What's going on?
17  Economy / Exchanges / BFX deposit: 10 confirms, and nothing on: November 05, 2015, 05:42:40 AM
I deposited 35 btc to my Bitfinex exchange deposit address
3LzMingj27S6UG39NFy3M3J1xVCkTZ1Qe8
The transaction has 10 confirmations as of this writing.
proof:  I have a screenshot showing the bitfinex deposit page showing the address.
I emailed that screenshot to bitfinex support.

I still have no coins in my account, and the deposit doesn't appear in "recent deposits and withdrawals."

I also have the transaction history in my Mycelium wallet.  I can sign the transaction, if further proof (that I was the sender) is necessary.

Edit

There is currently a slight delay on deposits being credited to their account. We're working on fixing this and getting all the deposits credited, it should be done shortly.

Our apologies for the inconvenience.

Please let us know if there is anything else. Thank you!

Kind regards,

Ninel Makhmetova

Edit:
Deposit came through.
18  Economy / Scam Accusations / Please help track stolen coins on: July 14, 2015, 04:59:53 PM
This is a venmo chargeback scam I fell victim to.  Lost about 4.34 coins.
The transactions went through paxful.com.  I contacted them and they were kind enough to send me a csv file of the scammer's transactions, with the address he (or she) sent the coins to.
The address is 13ZyZi4PQXyWoP6823oXXPQn7b8NfmZfSo
Later on today or tomorrow I will make another post or edit this one to indicate which of the transactions in 13ZyZi4PQXyWoP6823oXXPQn7b8NfmZfSo were the coins withdrawn from paxful.  This person's paxful account had no other transactions besides the trades with me.
The scammer used the name "Clotilde Teal" in his venmo account, Clotilde257 on paxful.
Gotta go now, will return with more info.  And thanks in advance for your help.

Edit:
All right, all the received coins from the transaction on 2015-07-10 16:33:57 to the transaction on 2015-07-10 19:07:35 were withdrawals from paxful:
.62300580
.37196322
.64940000
.64950000
.64990000
.11670000
1.28260000

After going through an intermediate address and getting bundled with coins from a bunch of other address, about 4 of the coins went to this address

20  Bitcoin / Legal / Does the wash sale rule apply to btc? on: April 11, 2015, 11:10:48 PM
According to the IRS,
"A wash sale occurs when you sell or trade stock or securities at a loss and within 30 days before or after the sale you...
Buy substantially identical stock or securities..."

I did a lot of trading last year.  I had a net loss.  And as I was going back through the records of my trades, I realized that if the wash sale rule applies to my trading, most of my trades with losses will be disallowed.  The gains will remain, and be taxed.  I would go from having a pretty substantial net loss to having huge gains on the Schedule D.  So not only will I have lost money in real terms in 2014, but I will owe a lot of tax on non-existent gains.

The IRS defines bitcoin as property, not as a "stock or security."
By closely applying the letter of the IRS publications, I would say that the wash rule doesn't apply to bitcoin trading.

Opinions?  Maybe someone even has direct experience of dealing with this.
