SmallChange [research-only] [Litecoin based] [15 seconds blocks] [*update now*]

[paul21]

I'm beginning to wonder if the "research" aspect of this coin is related to 51% attacks and DDoS takeover and things like that... 

[lightenup]

I think this coin requires someone who can develop it futher Such as new name, make diff adjustment act work better etc

by all means, please do so! The Bitcoin/Litecoin development process in the readme could also work for us. In case you want to try something out, please give me a pull request.

I can't seem to reliably maintain connections, sometimes I have 9 or more than other times I have 0. Happening on Linux and Windows clients.

We don't have many stable nodes currently.. Most people connect only temporary.

Yes, secretly a botnet is built. Have you checked the source code? Na, I have no idea why this coin or its pools would be of interest to any attacker. Maybe they also only play around and test out things like we do :/


next update
From my part, the next update will be in a little over a week (4th or 5th) -- that will be in regard of block size, difficulty adjustment and tx fees. Any ideas how we could crank up transactions are very welcome.

I'm almost there with a pool. The website just needs a lot of work (hard-coded 50 BTC rewards in the code, etc) and I have very little time atm.

I don't understand how you people are mining this coin when I can't even get any connections...

Hi there,

Following this from the beginning, I am finally allowed to write 
Me too I missed the launch time because I went to bed and things moved quicker than I thought 
Now I'm having rather consistently between 6 to 8 connections.

[c4n10]

If anyone else is having trouble maintaining connections, I found this earlier in the thread and so far it seems to have fixed the problem for me. Just use this for your smallchange.conf file:

Code:

addnode=54.246.222.7
addnode=80.123.216.178
addnode=199.195.214.166
addnode=74.121.182.150:16001

server=1
 
rpcuser=...
rpcpassword=...
rpcallowip=127.0.0.1
rpcport=9031

[c4n10]

Ok, now my Linux client is stuck on block 20,485 and my windows client is up over 27,400...

I have 12 connections, I've tried re-launching my Linux client with -rescan, tried deleting the block index and re-downloading entirely, nothing works, just sits on 20,485...

EDIT: I re-cloned and re-compiled the client which seems to have fixed it.

+1 for creating an exchange. I have no time atm myself

   *) 420 699 680 total coins

I think it is 42 millions, not 420.
coin_reward x block_per_minute x minute_per_hour x hour_per_day x day_per_year x 5
4*4*60*24*365*5 = ~42 000 000

5 years later... wtf, where are the remaining ~378 000 000?!

Thanks, binaryFate.. a slight but embarrassing mistake!

15 seconds? Why not 10ms,....?

Exists one reason for time > 120 seconds; share result,... Core attack.
Proof-of-work in network, it's not suitable for fast verify.

Could you elaborate a bit what you mean by "share result... core attack"?

Proof-of-work in network, it's not suitable for fast verify.

It's true that the fork of the blockchain can be of significant length, therefore I'm
not sure it has a faster confirmation time, in terms of probability (time after which
a transaction as a given low probability to not be reversed).
But "not suitable" sounds  like solid conclusion, what supports this?

[RichG]

When I am compiling on my Ubuntu box, it is telling me it can't find "QTest".

Where do I get this?

Preferably, I would want a solution through APT.

[binaryFate]

Looks like something from Qt, can you report the full line of the error?

[Otaci]

OK, here it is. First, some disclaimers: I'm new to bitcoin et al. I have not run a pool before. I would not trust this pool with anything that is worth real money (e.g. BTC, LTC). I've been going through the web site code and it's horrific. I don't mean to offend the original author, but it just is. Lot's of respect to paul21 for running *.dontmine.me so well.

Ota's Experimental SmallChange Pool - http://sc.cascharia.com/

It's a pretty standard pool, shouldnt need much explanation. Please do give me feedback, I will act on it as fast as I can.

EDIT: Stats are not working, thats next on my list.
EDIT2: Stats fixed. Turned out to be a minor fix.

Nice!
I've seen many pools with the same design, where are the sources from? I'd be curious to see how it works.

I shamelessly got the sources from http://fc.dontmine.me/. I've added links to the footer of the pages to the sources.

[binaryFate]

RichG, try to apt-get libqt4-dev.

Maybe there is a network bottleneck with the pool, I can't get mush hash rate.
The more connections I open, the less hash rate each produces, so overall it
seems I am rather limited (I'm mining with cpu). Indicating a maximum number
of shares the pool is able to receive from me?!
I'll keep solo mining for tonight 

[RichG]

STILL no QTest, binaryFate.

[RichG]

Will someone PLEASE provide a Linux x86 binary?
