1  Bitcoin / Bitcoin Discussion / Bitcoin cash has a future against the Bitcoin ? on: January 08, 2018, 05:51:01 AM
With the Bitcoin being 8 times superior to the Bitcoin cash, what's the future of BCC ? It was supposed to be the new bitcoin, and now it's just one of those bitcoin forks.

Will this disappear and be forgotten ?
2  Bitcoin / Development & Technical Discussion / BIP0074 draft proposal (dynamic rate lookup) on: July 17, 2015, 02:35:23 AM
Please take a look at my BIP0074 draft proposal (this is my first one so may be incorrectly formatted)

This proposal will make it possible for a simpler form of Bitcoin payment at physical shop locations.

Currently when making a Bitcoin payment at a shop the merchant needs to have an app of some kind so that they can calculate the amount of bitcoins you need to pay them to cover your purchase (of for example: $9.99).

The problem is that many employees are not properly trained on the Bitcoin app, or the owner is the one with the app and he is often notthere.  When visiting "Bitcoin Accepting" estabishments you will often run into this problem.  The businesses often don't get enough Bitcoin business to warrant training sessions or dedicate hardware to run the app.

A simpler way to accept payments would be for the merchant to have a fixed QR code, and no app at all.  However a printed QR code can't calculate any exchange rates, and so it would be up to the customer to choose how much to pay.

This can result in some problems as the customer may be using their default wallet exchange rates, or their preferred international exchange. While the merchant may be actually using a local exchange or service to exchange the coins to local currency, and there may be some discrepancy between what the customer thinks the rate should be and what the merchant thinks the rate should be.

Enter BIP0074, so that the merchant can specify which exchange rates they are using, and the customer and then look up the rates from this source and pay according to these rates.

*Note: The merchant would need to use some 3rd party service to receive SMS transaction notifications to be sure that the customer had actually paid; assuming they did not have internet to check the blockchain and did not trust customer.
3  Bitcoin / Electrum / Electrum BIP32 child keys on: June 13, 2015, 01:42:48 AM
It appears that Electrum can only be used to monitor addresses in the first level of the xpub (ie /m/0 ).

Is it possible to configure it to generate child xpubs and monitor / spend from those addresses also?
4  Bitcoin / Bitcoin Technical Support / How to improve bitcoind signing performance? on: April 28, 2015, 02:00:36 PM
Currently using bitcoind 0.10 headless on Debian (although had the same issue with all previously bitcoind versions).

The wallet info:
Wallet.dat size: 160MB
Number of addresses: ~16,000
Unspent outputs: (varies but around: 20-40)

The signing function is quite sluggish.   Even for simple 1 or 2 UTXO the signing takes around 2-5 seconds.
With more complex transactions the signing can take more than 30 seconds!

Is there any way to speed up this process (preferably without having to do UTXO consolidation transactions, and just via a setting change)

Load on the server seems fairly low, and CPU usage is very low.
Memory: 4GB
load average: 0.39, 0.43, 0.35

6  Economy / Service Discussion / Not able to withdraw USD, anyone else having this issue? on: March 15, 2015, 04:32:27 AM
When trying to create a USD withdrawal in, using the same bank account that I always use, it is popping up a message after clicking the "Confirm" button:

Withdrawal request failed
Parameters did not pass validation.

Waiting for support to answer; but is anyone else able to create USD withdrawal requests right now?
7  Bitcoin / Electrum / Cosigner pool on: February 02, 2015, 03:24:58 AM
Where can I get more details on how to use the co-signer pool?

I have taken the following steps (in 2.0 beta):

1) Setup a single-sig wallet
2) Used the master pub key (from #1) to setup a 2of2 multi-sign wallet
3) Turned on co-signer pool plugin in my multisig wallet
4) Created a send transaction in my multisig wallet and clicked "Send to co-signer"
5) Open single-sig wallet and tried to turn on the co-signer pool plugin but cannot because it is greyed out

So how can I sign the 2nd signature via the pool using my single-sig wallet?
8  Bitcoin / Bitcoin Technical Support / Running bitcoind across multiple connections on: November 04, 2014, 10:24:14 AM
I have bitcoind setup with a fallback connection on the network.

So if the primary internet connection goes down, a secondary backup connection automatically kicks in.

The problem is that when the connection/IP is changed all existing peer connections hang and take really long time to connect to different peers.

Possible solutions:
- Is there a way to set a peer ping timeout?  So that if a peer takes longer than say 10seconds it is replaced
- Is there a way to force bitcoind to reconnect/replace all new peer connections?

I'm guessing many of the existing peers are already tied up with the primary connection IP, so potentially do not have any free spots for the new IP, so probably would need to find new peers.

10  Economy / Service Discussion / Bitstamp: No withdrawals for Bitcoin related companies on: August 22, 2014, 09:44:01 AM
A few weeks ago our company requested a wire withdrawal from our Bitstamp corporate account.

After a week the money came back into our bitstamp account (at a $45 cost to us) with bitstamp saying: "The reason for the failure was stated as a breach of a recipients bank's Terms of Service."

This is quite worrying so we contacted our bank, and no they had not seen or rejected any transfer; and said they'd need to see the SWIFT transfer form (MT103) to check it out further.

Bitstamp then had the nerve to ask us to pay $40 extra just to get the proper receipt of the transfer; which we paid.

The receipt, that we paid $40 for, shows only that they transfer money between Raiffeisen Banka d.d. to Raiffeisen Bank international....and the RBI had rejected to process the transfer saying that they do not execute transfers related to Bitcoin...

Talking to Bitstamp is like talking to a brick their opinion Raiffeisen Banka is their bank and Raiffeisen Bank international is an intermediary; therefore we have to pay all the costs of this botched transfer and can seemly no longer withdraw funds (because of this intermediary that is supposedly totally unrelated to Bitstamp or their bank)

End of story we paid $85 for a transfer that was never sent to our bank; and we have no way to receive any transfers because bitstamps bank/intermediary will not send to Bitcoin related companies...


Bitstamp support seems to see no real problem with this situation.

- We have previously done many successful wire transfers with the last one being about a month ago with no problem.
- Our company name has "Bitcoin" in it.

Here is a Memo from Bitstamps intermediary (basically Bitcoin hate mail):

14  Bitcoin / Bitcoin Technical Support / Multisig Listunspent not showing on: June 20, 2014, 07:35:40 AM
I'm just starting to play around with multisig and I'm having an issue with listunspent not showing the multisig addresses (using Bitcoin Core 0.9.2)

Setup: 1 online machine (with full blockchain) and 1 offline machine.

Steps taken:

1) On each machine generate an address ('getnewaddress')

2) On each machine also get the pubkey for the address via validateaddress (and backup the private keys)

3) On the online machine do "addmultisigaddress" for a 2-of-2 with both pubkeys
bitcoin-cli addmultisigaddress 2 '["pubkey1","pubkey2"]'

4) On the online machine do "createmultisig"
bitcoin-cli createmultisig 2 '["pubkey1","pubkey2"]'

5) From another (unrelated) machine send some coins to the newly created multisig address

6) The coins show up in, but in listtransactions and listunspent on the online machine it does not list the transaction?

I was reading that in order for the multisig address to show in the unspent list then all the private keys need to be available for the multisig address...but this makes no sense as it would negate the point on the multisig address if you have the private keys stored together.

For a bit of fun in some spare time I setup the website:

Pretty simple idea.   You can "HODL" the page by paying double the Satoshis of the last holder.

You can upload any picture (please no sick shit as I will remove it) and a message, and it will stay as the homepage indefinitely until someone else doubles your price.

20  Economy / Service Discussion / Bitstamp Deposit Bug on: April 24, 2014, 01:37:45 PM
There is a bug in the Bitstamp system whereby if you receive 2 or more deposits in the same Bitcoin transaction only 1 of the deposits get recorded and the other deposits never appear in your account.

This can easily occur in many situations, for example:

Example A)
You have a number of different Bitstamp deposit addresses.  You make a withdrawal from an online exchange (such as BTC-e) to address A.   Then a few minutes later you decide to make another deposit to Address B.  The two transactions happen to be grouped together into one 'sendmany' from BTC-e to Bitstamp.

Both amounts will arrive at Bitstamps wallet, however the second payment will never appear in your account.

Example B)
Two different people who happen to use the same online wallet system (do not know each other).  They both make transfers to your Bitstamp account.
If the payments get group into the same 'sendmany' transaction you will only receive one of the the payments.

Example C (untested the most serious case):
*I have not tested this example but following the above logic this could happen.
Two different people who don't know eachother both using BTC-e.  Both make a transfer from their BTC-e to their own Bitstamp accounts.  The sends get put into the same Bitcoin transaction.  Only one person gets a deposit.

Bitstamp have been informed of this bug but seem unwilling to fix it.  Although they will correct missing individual deposits if discovered.

I urge Bitstamp to fix issue bug immediately. Sendmany is a part of the way bitcoin works and should not result in loses to the user.

If you receive a lot of deposits to your Bitstamp account it can be easy not to notice a missing deposit; I'd suggest all users export their deposit history and check that all deposits have been accounted for.
