Excuse me if such question was in the topic before.
 The process of calculating tokens is understandable, as well as binding to the amount of advertising.
 This is not entirely correct,(in my opinion  Smiley)  because we have a variations of connection speed, and process of calculating  tokens should depend on it too.
What do you think?
Thank you.

Why the wallet on Poloniex is in the switched-off state already it is more than one year? I not really understand what this problem is connected with, someone can explain to me?

Good afternoon, gentlemen!
I've got the same question,mentioned above.

Plus, I'm very concerned that Novaexchange is closing, and the official Bitmark wallet is not synchronized on my PC.
 Huh there are zero connections with Bitmark blockchain. Huh 
Can anybody help me with this problem? Thank.

I have high hope for this project. Not every company can offer investment in innovative production, which is in demand and brings people benefits.
 You have a long and hard road ahead, and I wish you success in overcoming this way. Wink

We can use escrow or i send 40$ first to try you. i wont send 190$ first
thanx

I have 190$ paypal which i can not withdraw cause paypal did not allow my country to withdraw funds. so if anyone interested please let me know
you can hold BTC money with escrow for 1 week just to be sure that funds from secure source and not stolen.

2. Does this unit get MPP? If so are we(the buyers) entitled to it?

Does it matter? By the time HashFast ships their MPP you'll be able to buy a 2TB USB miner for $5.
92  Bitcoin / Development & Technical Discussion / Re: What is normal outbound traffic for the Bitcoin-qt wallet? on: April 19, 2014, 07:34:20 PM
is that newly installed and fetching block data ?  not experienced such traffic in my qt

No, the wallet has been up for months. I've upgraded a week before, but it didn't pull a new blockchain.
93  Bitcoin / Development & Technical Discussion / What is normal outbound traffic for the Bitcoin-qt wallet? on: April 18, 2014, 09:07:07 PM
I have a Bitcoin-qt client running that is doing 6gb of outbound traffic per day.

This isn't even an open wallet (i.e. the inbound ports are firewalled) - so this is just outbound traffic initiated by the wallet itself. I take it when the wallet connects to a peer, the peer then can in turn retrieve blocks from the wallet, which is where the traffic comes from.


Is 6gb/day normal usage though?

If so, is there a way I can trickle it down?


I want to support the BitCoin network, but 6gb a day is a bit excessive (I have to pay for all outbound traffic - this ends up being $100's per year).

Like See if we can get the hash with the certain amount of 0's beforehadn, and if we find one, then submit it at any time

No. You need the hash from the previous block that was solved in order to create the new hash.

Does anybody know the answer?
96  Bitcoin / Development & Technical Discussion / Re: Are transactions too slow? on: March 24, 2014, 05:06:11 AM
There has just been a number of instances lately online where it has taken me upwards of 30 minutes to an hour to get a single confirmation.

Not to mention the services I use require at least 3 confirmations (exchanges) -- it can get annoying.

There has been a number of instances lately where I have deposit a check in my bank account and it has taken me upwards of 3 days before I could spend the money.

Not to mentioned that the services I use require at least 3 days of confirmations (exchange like Ameritrade) before I can use the money over there -- it can get annoying.
97  Bitcoin / Development & Technical Discussion / Effect of orphan blocks on bitcoin wallet API on: March 22, 2014, 05:17:29 PM
When a couple of blocks are orphaned, I assume the following will happen.

Can someone verify this is correct? (Kind'a difficult to test).

Let's say there is a two-block fork:

   291873
     ^
     |
   291872
     ^
     |
   291871  291871
     ^       ^        
     |       |
   291870  291870
     ^    ^
     |   /
   291869
     ^
     |
   291868


And the bitcoin wallet went down the right-hand-side (incorrect) fork until 291872, and then jumped back. It's behavior would be:

a) Prior to orphaning, getblockhash returns one set of hashes for the blocks at that height:

  getblockhash 291869
  00000000000000004674e91dd6efeac7255d1de13fadc55261241dcb6d8397b5
  getblockhash 291870
  0000000000000000e8033afc5dfad298a95c73cbe7bc11186c7544460c007fde
  getblockhash 291871
  000000000000000079557def76dddcd2c93da1b66c4371a714223bdb6c5d7ae4


b) Once the orphan chain is detected and resolved, those block heights values will now map to different hashes. E.g.:

  getblockhash 291869
  00000000000000004674e91dd6efeac7255d1de13fadc55261241dcb6d8397b5  // still the same
  getblockhash 291870
  0000000000000000419cfd8ed2fc0e919c1cdb20f4fb009a4a19fdd7a20d5961 // new hash
  getblockhash 291871
  0000000000000000a2185dc7779f93831925909cb489e8e7a9d007beee0cc619  // new hash

and after this point, life will be good again. getblockhash 291872 will return the new valid hash from the main chain etc.


c) The previous hashes will still be usable to retrieve the orphaned block information directly (e.g. through getblock), but getblockhash will return a different block at that height.

d) Since the wallet jumped back to the main chain, there is no other way to enumerate these orphaned chains again unless you kept track of it while it was happening and scribbled away their hashes.

I have a Java Base58 encoder/decoder which works directly with the byte array.  But I don't know that it is any faster than what you are using.  If you want to check it out, https://github.com/ScripterRon/BitcoinWallet/tree/master/src/BitcoinWallet/Base58.java

MOD by long division. Far out!

Thanks!
99  Bitcoin / Development & Technical Discussion / Base58 without bigint? on: March 21, 2014, 10:21:43 PM
Does anybody have an snippet or theoretical algorithm available that can encode a byte array to Base58 without using BitInt? (Instead using chunks or some other technique).

I can do this in my sleep for Base64, but Base58 makes my head hurt.


I created a blockchain scanner, and it's spending 70% of it's life now in the Base58 address conversion (Using BigInt from BouncyCastle). Argh.
