Pebblecoin (XPB) - FIRST DPOS CRYPTONOTE COIN LIVE - Qt Wallet GUI - v0.4.4.1

[GingerAle]

Is there a list of all known pools?

So far I have:

69.60.113.21 (main OP pool)
23.251.155.86 (pool advertised here: https://bitcointalk.org/index.php?topic=945893.0)
xpb.noteminer.com

[1714801119]

Okay, unfortunate analysis. Please prove me wrong, because I like the concept of this coin.



I used the print_pl in the daemon. Collected all nodes that were connected during the past 24 hours, both white list and grey list.

Total network hashrate: 45.53 H/sec (from above pic)

50 active nodes (from print_pl output)

Known pools
69.60.113.21 has 76 connections at 3.81 H/s
23.251.155.86 has 0 cnxs
52.1.11.212 (xpb.noteminer.com) - has 2 cnxs at 0.9 H/s

45.53 - (3.81+0.9) = 40.82 H/s unexplained hash leftover

Now, lets just assume there's 50 nodes, even though there may be many fewer in reality because i used hour < 24 as my selection criteria.

40.82 / 50 = 0.812 Hashes / node.

So either someone is pouring tons of $$ into servers to mint this coin (because I looked it up and the servers required for this coin are pricey), or someone has found an exploit and hasn't reported it.

Comments?

[GingerAle]

So, I continued diving into this, and have this to report.





Overall, my concerns regarding the network hashrate in my first analysis still stand. Regarding exploits early in coin history, the design of the coin (start with slow release) actually worked, because there may have been something going on prior to the release of the exploit, and the exploit was announced during the ramp to 300, so there was no intention to maximize the exploit. Thus, I am not overly concerned that there was collusion early in coin history regarding exploits. Period A may be others finding exploits, or just a whole hellalotta people joining that pool.

I probably spent way too much time on this. And it took a lot longer than normal because my damn computers so laggy from this goddamned miner!

Oh is there a difficulty exploit? I should probably read this whole thread.

[qinhaotian1]

windows miner don it work   

[e1ghtSpace]

I have only 8gb ram. Would it work?

I believe you could set up your miner to run with a pagefile, but it will be ungodly slow.

What about vram??

At EC2 spot pricing, it would only cost ~$70/hour for 50H/sec. Someone might just be trying to acquire a good number of coins.

Pretty sure paging is what you're referring to.

No, I meant, would it be possible to use ram from your graphics card as well as ram?

Has anybody actually succeeded in using Poloniex to buy/sell XPBs?  A lot of people have issues.  I will take the link off of the first post until people confirm that it works.  If it works for some and not others, then why?

I have - simpleminer must be used to xfer coins.

What is the difference?  The Qt Wallet uses the same code as the simplewallet.  Did they accept it as-is or you had to give them the txid?

As-is - you can't specify the ID in that GUI.

Will this be added into the GUI wallet?

Hey Wolf, are you working on an 8GB miner? Because I would like one.

I don't really want to - not much profit in it, seeing as it won't be a ton faster.

Fair enough. Although it will be a ton faster than a paging file, right?

Oh, yeah - loads.

How long would it take you to code it?

Many of them mining without opening ports? i think there are more than 50 active daemon miner

[PeaMine]

I have 700 coins unconfirmed on the main pool from op

[goofy73]

Not bad. Server?

No, home pc, 2 Xenon 5560+supermicro x8dtl-i.. 70% games, other 30% is video monitoring and some services. and of course mining =)

[barabeku]

Getting 0.05H/S is this normal for a i7-4770K with 16GB of RAM?
Using all cores by default, and about 2GB RAM free.

Yes, that is pretty good.  I am only getting 0.03 H/s on my 24GB machine, not sure what the processor is.

how many blocks can you mine in 24h??

The difficulty is currently 1462, meaning you have a 1 in 1462 chance to mine successfully.  If the hashrate is 0.03 H/s then it'll take  1462 * (1/.03) seconds, or 13.5 hours to make 1462 attempts, which give you an expected value of 1 success.  That means you should be able to mine about two blocks per day.  I recommend using the pool to lower your variance.

WHY???

Difficulty: 2286
NetHash Rate: 38.10 H/sec

Means... 2286/38.10 = 60 sec (block time)

But why we still generate 120 sec block time? or why diff number is not 120*38.10=4572?

Someone can help???

[magaura]

Tonight we are going up again..
Just waiting for some miners dump.. do it!

Is anyone going to make an 8GB miner?

[GingerAle]

Is anyone going to make an 8GB miner?

you have to offer up a bounty. i n c e n t i v e

[barabeku]

Is anyone going to make an 8GB miner?

no, next fork will be 26GB boulderhash state   

[GingerAle]

no, next fork will be 26GB boulderhash state   

whether or not someone comes up with another exploit optimized miner is just a matter of time/value. If XPB shoots up to ridonculous value, someone will put the time in to try and get more coinage regardless of bounties. Look into what happened with any attempt to make a CPU-only coin. I've investigated monero's story the most. I don't have time to detail the story, but if you check it out there's a pretty clear relationship between coin value and amount of effort the community puts into trying to crack the coin, which makes sense. And personally, I'm all for.

So yeah, an optimized miner could be developed, and then boulderhash3 could come out with a 26 gb state, but then it'd be a matter of whether the community forks with that new POW.

And this gets to network consensus and the imperative of running a full node. but of course this depends on openness of the code. And I couldn't get the source to compile... granted, i'm noob+1 status when it comes to these things, but I managed to get monero to work, so thats worth sumtin.
