Seems i got the first block on my windows client and i got 1 on a linux server

I'm getting about 50 primes per sec total between my two computers.

Thats huge. Sitting on 0 myself.

Care to send a few? AHqCDCeSViVAZw9pEcmKD3KnSUgKBA4fXM

Thanks.
I haven't found any blocks though.

Did Sunny create a blockchain explorer before release?
225  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency on: July 07, 2013, 06:38:38 PM
How many "primespersec" are you guys getting? I have an i7-2700k and it is fluctuating between 20 and 120 primespersec for me.
i5 2410M getting 14
:c

The Linux download isn't working so I can't use my desktop.
226  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency on: July 07, 2013, 05:51:31 PM
I'm looking forward to this.

I feel a coin that produces something useful is a lot better than Bitcoin.

Where is the scientific use of prime number chains?

The discover of new prime numbers as I understand.
In the white paper it describes only using prime numbers which can be easily verified, so that rules out actively searching for large prime numbers, doesn't it?

Dude, verifying a number is prime is easy.
Well, I guess the white paper is pretty vague on the limits.
So we'll see what the actual limits are in a couple of hours.
When I discovered this coin last night, I had hoped it would be finding all prime numbers so that eventually bitcoin could be attacked using the prime numbers found by this coin.

Which would be poetic, imho.

How does increasing the amount of work, increase the energy efficiency?

So something that cost you 22000$ will now net you upwards of 140000?

Nice dude.
232  Bitcoin / Development & Technical Discussion / Re: In the event of a 51% attack, how would it be resolved? on: July 03, 2013, 12:43:32 AM
This issue was brought up in a reddit thread. And now I'm genuinely curious, the person I was talking to about it seems to feel that the major mining players could collude to exclude the attacker, and that would be an acceptable course of action.

So less than 50% of hashing capacity will ignore the longest chain?

There's a slight chance this would work if the attacker's capacity cannot be sustained.  For instance, if the attacker is a pool that miners will abandon once it they determine that the pool is attacking.    

But with "longest chain wins", every second that passes makes it more risky for the remaining miners to even try such a tactic.
Well, I wrote "the majority mining players" but I think he also meant that the client would be changed to exclude this attack chain.

I on the other hand feel that any action that shows how easily it is for the network to censor blocks would actually be more detrimental to the network than the attacker is (the attacker would only hold the majority power for a short span of time as ASIC hardware producers would most likely use their production capabilities to roll out more "legitimate" hash power) I believe that a 51% attack can only be resolved by increasing the legitimate network hashrate, not by excluding blocks.

Thoughts?
234  Bitcoin / Mining / Average value of the hashes? on: July 02, 2013, 05:10:06 PM
When miners are mining and producing block hashes, what is the average value of those hashes?

Since SHA256 is supposed to be uniform distribution the average should tend towards 2^255, right?
235  Bitcoin / Development & Technical Discussion / Re: Blockchain corruption during power loss? on: July 02, 2013, 04:25:00 PM
nope.... I just restarted the client, then is had an error and said it needed to reindex the blocks(i imagine the blockchain stored on my computer), then about an hour later it was done, probably not even an hour...... i set it to low priority
Hmm, well I'm almost certain it didn't say anything about indexing the blocks, it was more could not read the block. So at first I tried deleting all the lock files and it still didn't work.
236  Bitcoin / Development & Technical Discussion / Re: Blockchain corruption during power loss? on: July 02, 2013, 04:09:30 PM
i had this also during a power outage... only took an hour or so to reindex the blocks htough
wait what

you mean I didn't have to delete everything?
237  Bitcoin / Development & Technical Discussion / Re: Blockchain corruption during power loss? on: July 02, 2013, 04:06:47 PM
How ironic, I just had the same problem. I had to remove the program and the associated files and then reinstall the entire program. Fortunately, I keep several backups of the wallet.dat file. Now, my computer has been running non-stop for the last 7 hours updating the blockchain - only 16,000 blocks to go!


Oh good, I was afraid it was cause of the modifications I made to my bitcoind that scan transactions for specific addresses and keep metrics on them. But since you also had the same issue I have ruled that out, thanks.

I should probably start backing up my blockchain at regular intervals to prevent this from happening again.
238  Bitcoin / Development & Technical Discussion / Blockchain corruption during power loss? on: July 02, 2013, 03:55:58 PM
I lost power the other day while my bitcoind was running, and I went to start it again and it was unable to read the blocks. I'm currently in the process of redownloading the blockchain.

Has anybody else had this issue?
239  Bitcoin / Mining speculation / Re: Should BFL Stop Taking New Orders? on: June 25, 2013, 08:44:06 PM
Even at 400M difficulty and .15 $ per kwh you'd only have to theoretically produce 29GH/w (more if you use a pool) to cover electricity costs, the Jalapano gets around 133GH/w so the 50GH unit probably has 120-130 GH/w efficiency due to more chips and stuff.

So there is no reason for them to stop taking orders as their units will be useful for a while.

Blockchain as a Service sounds interesting...

You could offer "quick propagation" of transactions and what not...

Use a SSD to get maximum read speed for the blockchain, you could act as the blockchain for potentially hundreds or thousands of paying customers that pay you not only to lessen the load on their storage, but also to ensure their transactions makes it to the next block.

Once the blockchain hits 10GB, I can see a service like this becoming viable. You'd have to have pretty good internet to support the numerous connections and redundant transaction propagation. Even if you charged just a few cents a day, you'd only need maybe 10-20 subscribers to break even if you found cheap hosting, depending on how good EC2 is, you might be able to get away with the Small On demand instance that goes for .06$ an hour in N. Virgina. That would run you 43.2$ a month. Which is less than a hundred subscribers at .50$ a month. But if you haven't already blown the  free tier year, you could get away with that aswell.

EDIT: You could also offer "anti double spend" bullcrap, where you WON'T relay a transaction that uses the same inputs as one you already relayed. That would give your subscribers a perk, since you'd probably be a sizable node in the network.

I think I might try to do this. Wink
