SmallChange (SMC) - a 'faster' version of Litecoin which also uses scrypt as a proof of work scheme and is intended for microtransactions.

    *) 15 seconds block targets: beat that MinCoin! Wink
    *) 42 007 680 total coins
    *) no subsidy within the first 3 days and after approximately 5 years; in between: 4 coins per generated block
    *) difficulty retargets every 0.35 days
    *) currently peers are looked up over IRC only
    *) currently no block checkpoints are in the code (but could be easily added)

Other than that, this coin is exactly like Litecoin and should by no means be used as a real cryptocurrency. All of the coin parameters are chosen arbitrarily or at most with 'fairness' towards everyone in mind. [..]

But head over here for the client and more information:
https://github.com/bfroemel/smallchange.git

Cheers!


Any mining efforts are probably wasted efforts. Imagine this coin to be like a small Bitcoin testnet with it's own set of (untested) rules.

binary clients and building:
Please (learn to) make your own builds. Then you only need to trust the source code and your understanding of it: https://bitcointalk.org/index.php?topic=42465.0

However, Balthazar has put a Windows build up here:
https://bitcointalk.org/index.php?topic=182430.msg1923633#msg1923633

On Linux (e.g. Ubuntu, Debian) getting and building is as simple as:
Code:
# those steps need to be done only once
sudo apt-get install libboost-thread-dev libboost-program-options-dev libboost-filesystem-dev libminiupnpc-dev libdb5.1++-dev libssl-dev libboost-dev build-essential git
git clone https://github.com/bfroemel/smallchange.git
# every time you do a fresh build
cd ./smallchange/src
git pull # update local sources
make -f makefile.unix

For qt, see: https://github.com/bfroemel/smallchange/blob/master/doc/readme-qt.rst

Thanks for the overwhelming interest --> didn't expect that.

updates
2013/05/14 Many thanks to sido, who operates for now a node on a permanent IP: https://bitcointalk.org/index.php?topic=182430.msg2134304#msg2134304
 
2013/05/10  please update now (move to a (hopefully unique) network magic number), details: https://bitcointalk.org/index.php?topic=182430.msg2102353#msg2102353 and some of the following posts.
2013/04/24  the block reward was reached a bit earlier than planned and total hashing power is now around 12 MHashes/s, 46 peers; difficulty 'slowly' adjusts. Right now 22 937 blocks are mined and the current total smallchange around is: 22 628 coins.
2013/04/22  please update before block 15 000

Thanks for the honest advice -- I expected that my chosen coin parameters could break stuff Wink
but the whole thing is more intended to show where to change what in the codebase for 'rebranding' and that anyone can do it with minimal efforts. Hopefully it contributes to keep the value of those cryptocurrencies down that are just weak spinoffs (with questionable intentions) of 'serious' ones on the one hand and on the other I wanted to have something to play with for research reasons...

I understand, but at least the sampling interval increase would be helpful.  Roll Eyes

I.e. perform retarget every 0.35 days, but use last 1-3 day blocks set for target calculation. It will prevent some kind of attacks by users with high hashing power.

Let's not forget that no exchange is going to want to host a currency with 15s blocks, and the resources that requires. You would need the friggin obama hope campaign of advertising to generate enough buzz to sway an exchange to offer a coin with 15s block solves.

Maybe increase the block size to 10 MB and try 5s too, it'll be a contest for who can achieve the highest rate of orphans  Cheesy  A double-spend filled adventure!

Maybe.  Cheesy

But I prefer decreasing of blocksize to 16k or even 4-8k, because there is no sense of 1mb blocks at such blocks rate. That's may be interesting for currency which intended for microtransactions.

Yes, that's the obvious answer.  It remains to be seen if the Litecoin network will encounter orphan problems as time goes on with 1 MB blocks.  Bitcoin is already having problems with 10 min blocks, which is kind of scary.  Litecoin should probably have adjusted the block size to 256 KB.

you really wasting 1.35 MHashes/s ? okay Smiley

you mean: nInterval, currently at 8 hours ?

Code: (main.cpp)
static const int64 nTargetTimespan = 0.35 * 24 * 60 * 60; // SmallChange: 0.35 days
static const int64 nTargetSpacing = 15; // SmallChange: 15 seconds
static const int64 nInterval = nTargetTimespan / nTargetSpacing;

Sorry, no binaries and I also didn't test windows builds or the qt GUI build.. This "coin" is more meant for research, not as a currency (and as such maybe in the wrong forum section).

hope you have it sorted out soon, because SMC difficulty will go up soon and then it might not be profitable here anymore Wink

Hmm, if you have actually figured out all the right places in the code to change to make a new coin, you should be able to just as easily make a new updated version of Tenebrix the same way, that would be nice...

Thanks, but no thanks. Probably it would be a different situation, if I wanted to start a 'real'/practically useful coin.

ah yes a friendly reminder: That's a research coin. The changes to the litecoin codebase could have killed it from the start (as indicated in the second post of this thread).

Thank you for this, it's been fun setting this up, I've learnt quite a bit. I also intend to look at setting up a pool (I know there is one already but more than one should exist). For me it is a fun project, not a financial investment.

Okay - if it's not only fun for me then everything is fine Smiley

btw: please update as soon as possible, latest before block  15 000
Based on Balthazar's suggestion I've adjusted the difficulty retargeting algorithmus slightly to react a bit slower but be more robust with respect to sudden hashrate changes.
Now instead of 8 hours, the algorithm will look 1.5 days into the past to determine a new difficulty setting.

I wanted to say to everyone that I have inspected the sources of smallcoin using kompare with the sources of litecoin.  I am a University graduate and a programmer (though no longer in that career at this time).  The changes were largely search and replace litecoin for smallcoin with care to preserve case the changes advertised from the author but there was something unexpected.  The functions for returning the estimated number of blocks were altered to only return 0.  Why this change? Huh

the problem with really fast blocks is that one person with very high hashing power can potentially reliably out produce the legitimate network even if the total hashing power of the honest network greatly outweighs his own because he wouldnt have to deal with latency between nodes. This is why the block time needs to be at the very least set somewhere above the average time a block can be reliably propagated across the whole network in addition for a little bit of time for everyone to mine on it, or else confirmations give no security at all.

Now you have to consider that fast blocks can be much smaller than 1 mb bitcoin blocks and still hold much more in a given span of time so they could propagate faster than bitcoin blocks do so their is that. My guess is though that you are always going to have to wait atleast an amount of time that is at-least some what of a nuisance for face to face transactions and that is why gold and silver will always be best for day to day transactions. And when making a transaction over the internet, litecoins 2.5 minutes is a pretty good tradeoff imo.

Still new here, but why would the others have to deal with latencies between nodes? Even as a legitimate miner I'd mine as fast as I can. As soon as I have found a block, I blast it out to the others and start to work on something fresh. I wouldn't wait for any confirmations. If an incoming block interrupts me, I need to restart anyway.
So far, the one person with 'very high hashing power' has no advantage over the others (beside the very high hashing power).

Under the assumption the network delay has more influence on the block generation rate of the legitimate network than on 'bad nodes', yes.

I am not seeing this problem yet (coming from an entity that has higher than average hashing power but still has less than 50% (minus variance) of the total network hashing power).

But I admit that SmallChange surely has a long way to be considered practical in any way. If network delay is a problem with the 15s target block generation rate then it only adds to how to deal with very high transaction rates/bandwidth  (originating from the nature of microtransactions) and the required pruning... Also the difficulty adjustment algorithm probably requires a complete redesign... aw that's going to be great fun!

Imagine you want to get some snack from a vending machine at the airport ... and you need to wait 2.5 minutes... even 15 seconds is long!
I am not saying that this couldn't or even should be solved differently (e.g. by centralized systems/proxies where you transfer in advance an amount of your favorite currency to and vending machines can 'instantly' withdraw), but I wanted to explore the possibilities with a cryptocurrency based on Bitcoin. Might work, might fail horribly Smiley

/edit: it's a vending machine!

btw: we are at block 11087 --  in case you haven't yet: please update soon.

looking good:

old target rate algorithm (still active until block 15 000)
Code:
nActualTimespan = 44838  before bounds
GetNextWorkRequired RETARGET
nTargetTimespan = 30239    nActualTimespan = 44838
Before: 1e01a34b  000001a34b000000000000000000000000000000000000000000000000000000

vs. the new one:
Code:
nActualTimespan = 36350  before bounds
GetNextWorkRequired RETARGET
nTargetTimespan = 30239    nActualTimespan = 36350
Before: 1e01a34b  000001a34b000000000000000000000000000000000000000000000000000000

well if we had an honest monopolist than 10 second blocks could work ok =P. 

But just imagine that we have one actor with 20% of the total network hashing power and the other 80% is broken up among 80 actors with 1% of the total network hashing power each. Imagine that we have 15 second blocks and it requires 30 seconds for a block to propagate across the network. So lets imagine that in one experiment 10 blocks in a row are found by the honest network each by a different actor with 1% total network hash rate. So each block was solved in 15 seconds like the protocol dictates but inorder for each new actor to build upon an existing block it had to be transmitted to him and if it requires 100 seconds to propagate across the entire network lets say hes somewhere in the middle at 30 seconds, the fastest the chain could be built is one block every 65 seonds, 15 to mine 30 to transmit. Now the dishonest actor can build his own chain with out worrying about transmission thus each hash produced by him is roughly (65/15) 4.333 times as effective as a block produced by an honest actor and if he owns 20-30% of the total hashing power than he will be more powerful than any individual honest actor.

Sorry its a bit harder to explain with words than it is to picture in my own head.

You need to make it re-target every block. you can do this by adjusting based on an aggregation of data from blocks over a long period of time. Here is my 0.02btc on how i think retargeting should be handled for a fast coin (or any coin for that matter)

for example lets say the following sequence of numbers represents how quickly a block came in relative to how quickly it should have come in. So if the number is 1.4 and the block was supposed to come in at 15 seconds than the block actually came in in (15*1.4) 21 seconds.

block 1 = 1
block 2 = 1
block 3 = 1.5
block 4 = 1.7
block 5 = 1.4
block 6 = 1.8

ok so now lets say we are looking for the target dificulty of block 7 and the difficulty of the last block was set too 5000 (yes its a totally arbitrary number). Take each of the numbers on the right and multiply them times their block number than divide the total by in this case the 6th fibonacci number (since there are 6 items in the list). This will give more recient blocks more weight in deciding what the hash rate should be but still not enough weight for miners to see an advantage in arbatraging diferent chains and creating chain destroying ossilations by doing so.

((1*1)+(2*1)+(3*1.5)+(4*1.7)+(5*1.4)+(6*1.8 ))/(1+2+3+4+5+6)=1.5285

so in this example blocks are coming in to slowly, so we take 5000*1.5285 to give us a new difficulty of 7642.5

we then wait to see how long it takes for the next block to come in, and we devide the amount of time it took by the amount of time it should have taken and append that list now we have a 7th element

block 1 = 1
block 2 = 1
block 3 = 1.5
block 4 = 1.7
block 5 = 1.4
block 6 = 1.8
block 7 = (time the block in the previous example took/time it should have taken)

and just repeat the process above with the new data

The longer you set the sampling of blocks the less adaptive it will be but the more secure it will be from miners hopping back and forth on this chain and other chains and causing destructive reverberating oscillation. You would need to set the right balance. My guess is 1 years worth of samples would be about right.

I apologize if this made no sense, if it didn't than maybe ill see if i can code it in python to explain better.

Ah here we go I think I got it working.  Putting my low intensity 7950 to work on these blocks while I'm using my computer to surf the web lol.   And yes this is a waste of a 7950 lol

@Balthazar: Thanks you for the binaries.  I spent a couple hours trying to get this built today, but I'm obviously missing a step.  Berkeley DB make fails out during build (in MinGW).  I'll figure it out, but these will let me poke at SmallChange while I'm working on it.  It's appreciated.

Anything special I need to do to find peers, or just be patient?

edit: Nevermind, found the AddNode.  I'll toss 400KH at this, for kicks.

So the rewards start after 3 days. Is that bound to a specific block or will it sart with a update?

Rewards should start at block 17,280 (I think).
We're currently around block 16400.

I have 1 connections!   Grin
Is it me?  It might be me. I have 8.

In other news... my miner keeps suggesting I have shares being accepted.  I assume those would eventually be blocks, since I'm solo mining?

I like the delayed reward at the start of the coin.  Between that, and TacoTimes coin launch suggestions, you could get a very fair launch.

I pointed some miners at it... got quite a few blocks -- but nothing showing up in the display.
I rescanned --- nothing.  Nothing showing in listtransactions... nada.

I've been using cudaminer... I've been getting a ton of accepted shares...  but I'm not in a pool; I'm solo.  Are those blocks?  I'm so confused... :-p

Up to 20 connections now, and almost block 16900.  We're chewing through the last of these starter blocks pretty fast.

When you are solo mining an accepted share equates to a found block.
If it's rejected it would show up in the reject column.

It took a couple minutes for the first transactions to post to my wallet.  They're coming, unless they got orphaned I guess.  Is that possible this early?

I'm... not able to help here.  I had 2 that showed up early as transactions, but the coins didn't post for a few minutes.

It sounds like you have orphaned blocks.  Maybe a side effect of the bandwidth or latency requirements?

So who here has some serious hashing power?  How are you doing?  It'd be interesting to hear from those that catch the front of this wave...  give a little perspective on how the launch of a coin looks from the winning side.

I'm clocking in at about 400KH, which I figured was pretty chump change, but I've managed to grab 17 blocks so far, although only 6 appear to have survived to the primary blockchain.

I'll be checking up on the pool. I just updated the scripts to pay 4 coins a block, but I'm seeing a lot in the server wallet but I'm working on getting it paid out.

I had to lower the N  last shares quite a bit since the blocks come so fast.

I guess I should join your pool.  I thought I saw doing ok, but we just broke 18280, which means 1000 blocks have been generated, and I only saw 27 of them, and only kept 12.

Well, the pool was acting as an unintentional 51% attack.  The pool was essentially dictating the primary blockchain;  solo miners were lucky to find anything.  I've joined up now, and the find rate is ridiculous.

The blocks are coming sooooo fast. Pool efficiency is like 30%! lol

Don't forget --queue=0 --exipry=1 and you should be able to get over 50% even with this silly block rate.

I'll be honest...  i don't think you'll be able to solo mine this.  the Pool is just walking over everyone.  The internal latency of the pool, or lack thereof, plus the combined hashing power (current 42MH and rising), means solo miners get the crumbs if anything.  When i was  solo, I found 28 blocks...  16 orphans.  On the pool, my stale rate is about 20%, instead of the 80% I saw solo.

Things to consider when launching a coin...  maybe create 3 pools, and some incentive for people to spread out and complete?

I'll be honest...  i don't think you'll be able to solo mine this.  the Pool is just walking over everyone.  The internal latency of the pool, or lack thereof, plus the combined hashing power (current 42MH and rising), means solo miners get the crumbs if anything.  When i was  solo, I found 28 blocks...  16 orphans.  On the pool, my stale rate is about 20%, instead of the 80% I saw solo.

Things to consider when launching a coin...  maybe create 3 pools, and some incentive for people to spread out and complete?
can you pls post your config  Embarrassed
i've just added --queue 0 --expiry 1,but nothing changes

i am not doing too bad solo mining @ 2.5Mh.
Still pulling several blocks per minute.

I will NEVER ask for any kind of funds up front in a buy/sale of anything on bitcointalk.

You can add the node

sc.dontmine.me port=16001

I'm not sure what you're asking for...  I'm using cudaminer for my mining, so there aren't really any config options.  You're already out-hashing me 15:1 on the pool... 

my smallchange.conf:

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

That's it.

Someone else is going to have to help you with that.  I don't know how the normal miners apps work for scrypt mining.  nVidia card here, so I use the appropriate tools.

At best, I would suggest you do anything you can to minimize latency between you and the pool server.  I have a hunch that's the biggest bottleneck of this coin right now.  I see you putting up shares on the pool... 

edit:  Did the pool just glitch out?  Stat reporting just got a a little weird.

Lol I mined a bit.

Here is the question, we discussed it before with some folks. When u solo and say u 1% of total hash or 5% or whatever percent according to theory of probability u get portion of blocks equal to your portion of hash rate. Provided u also connected to many nodes and run fast internet Smiley

So pool really does not offer alot when coin just starts. Your thoughts are welcome Smiley

Actually the hash rate calc was way off on the pool (oops!) but it should be reporting correctly now (with stales accounted), but who knows. The pool is getting about half the blocks (1/2 of the net rate)

Glad to seer you working on it.  It appears to be reporting weird still.  I'm averaging about 340KH, with 80% acceptance...  but it's reporting 40KH.

edit: I wonder if the fast blocks is actually cutting into has rate...  the miners can't get their teeth into difficult problems, so your report is actually correct?  Overhead from changing work is causing significant loss/misreporting of hash rates?

I think there's benefits both ways. On a coin like this, where latency to blockchain updates has significantly more weight than normal, the pool makes more sense to me.  If hash rate was the sole determinant of income, and you were confident you could maintain a consistent portion of the network total, and you were ok with random spikes and droughts in income, then solo could work to your advantage.

The pool sees my rate as hilariously low and I seem to get a lot less than I do soloing even though the reject rates are crazy higher solo.  Oh well, it was pretty fun but I don't think the super quick 15 second blocks works all that well.

I liked solo up front, but now that the pool is in full swing, I don't have enough hash to compete...  and the pool is paying out pretty well, frankly.

Alright, crashing out.  It's been fun.  Do we want to do anything with this after it's been mined, or is the experiment effectively over after the next days?  Maybe set up a couple test sites to check it's feasibility for microtransactions?  Test it against Dust, and chain bloat?

I'm not entirely certain how GPU rendering works through TeamViewer.  I know I can't start a miner through a Remote Desktop connection.  It may be the same problem.  Also, 127.0.0.1 may be confusing during a TeamViewer session.  :-p  Which one is localhost?  ;-)

edit:  Also, isn't cgminer up to v 2.11.4?  I don't know what he fixed, but updating may help.  (shrug)

So some learning experience:
The scripts for the mmcfe assume that they get run at least once every 120 confirmations. Not so true right now for smallchange Smiley

So It's crunching the backlog right now and it should pay out soon, there's a lot of unclaimed coins on the pool's wallet and I'm trying to get the payments generated.

Edit:

use --queue=0 --expiry=1 -s 1

I don't envy you.  You're basically taking the brunt of a huge pile of traffic.  Thank you.

I assume you're trimming front-end functionality to allow more CPU time on the backlog?  It's stopped updating a few minutes ago.

Yeah kh update is deferred until the share calc script has finished up, and the stale rate is high as a function of block work changing so often, so it will probably be bad until

I think the Pool is severely under-representing itself right now.  If I had to guess, the pool is closer to 6.5MH atm.  But that's not terribly important, compared to working on the backlog and keeping things running orderly.  We can worry about the front-end later.  :-p

Yeah, I'm on the pool.  It pays better when you don't have MH to throw around.  Although I've got my CPU mining solo as well, and it's still stumbling across blocks here and there.  Not bad for 5KH.
what is your accepted/rejected ratio
About 15% reject rate.  I restarted a few minutes ago:

I don't know what just happened, but the pool is suddenly significantly more responsive. If this happens to coincide with bopbeep leaving for a few minutes, that seems to imply SMC needs a pretty beastly server to run a pool.

Now I feel like a damn tween but is there a flag in Guiminer-scrypt to turn off stratum? It seems to default to Stratum and get whiny when it's not available. And I'm lazy enough to like guiminers pre-configured GPU settings for using my desktop/dedicate mining.

No worries.  Instead of:
stratum+tcp://sc.dontmine.me:29339
just use
http://sc.dontmine.me:29339

SmallChange (SMC) - a 'faster' version of Litecoin which also uses scrypt as a proof of work scheme and is intended for microtransactions.

    *) 15 seconds block targets: beat that MinCoin! Wink
    *) 420 699 680 total coins
    *) no subsidy within the first 3 days and after approximately 5 years; in between: 4 coins per generated block
    *) difficulty retargets every 0.35 days
    *) currently peers are looked up over IRC only
    *) currently no block checkpoints are in the code (but could be easily added)

Other than that, this coin is exactly like Litecoin and should by no means be used as a real cryptocurrency. All of the coin parameters are chosen arbitrarily or at most with 'fairness' towards everyone in mind. [..]

But head over here for the client and more information:
https://github.com/bfroemel/smallchange.git

Cheers!

/edit: layout corrections, topic clarifications and notice:
Any mining efforts are probably wasted efforts. Imagine this coin to be like a small Bitcoin testnet with it's own set of (untested) rules.

binary clients:
Please (learn to) make your own builds. Then you only need to trust the source code and your understanding of it: https://bitcointalk.org/index.php?topic=42465.0

Thanks for the overwhelming interest --> didn't expect that.

updates
2013/04/22  please update before block 15 000

Please include more detailed build instructions for Linux.

As paul21 told us earlier, the script is lagging.  Just relax.  Let it mine.  Take a nap.  It'll catch up once the difficulty slows blocks a little bit.

Probably.

Appears so.

We were getting a lot of blocks from Unknown in there, all the sudden.  I wonder if we just got 51%'ed.

What is the goal of this experiment anyway?

I'll pull the wallet from it (ipv6 is safe) and send the coins out to the miners, but it will be down for at least 24 hours.

You were DDoS'ed?  That's ridiculous.  /facepalm  Who...  why...  arg.

Right.  The internet.  

I bet it wasn't a DDoS...  just a botnet that wanted to join in the scrypt mining.  :-p

edit:  let us know if there's anything we can do to help.  CloudFlare Free isn't a bad idea.  I may pick it up for my own websites, now that I'm more involved in this type of community.

Nice disucssion! I'll come back to that.

Thanks!

Quote from: Cheshyr
Things to consider when launching a coin...  maybe create 3 pools, and some incentive for people to spread out and complete?
Yes, good point. Also the launch strategy itself would do good with some adjustment. It might had been better to gradually give more block reward than instantly give the full one at some arbitrary point.

Alright, crashing out.  It's been fun.  Do we want to do anything with this after it's been mined,
I'd be interested in debug files of solo miners (e.g. ~/.smallchange/debug.log; shouldn't contain anything sensitive, but you might want to send it directly to: bfroemel [at] gmail [dot] com). I did some solo mining too during the night, but with ~10 KHashes/s you get only so much of the whole picture.

or is the experiment effectively over after the next days?
It's p2p.. it's over when the last one quits. I'll play around a bit longer, but of course it never was/is intended as a serious coin.
Overall, I'd call this experiment already a great success!

Quote
Maybe set up a couple test sites to check it's feasibility for microtransactions?  Test it against Dust, and chain bloat?
That's a great idea. Eventually I'll post results from the data collected here along with some discussion -- but that might take a bit.

Done. See first post.

Ouch - but thanks for the pool. Are there log files? Wink

It's not my project, just built it for win32.
And I added a link to that post in the first post. In general, I still oppose binary releases, but if they come from a trusted member they are okay I guess. Thanks (again), Balthazar!

Well the coin seems fun Smiley I like LTC, FC and this one. How can it work with such fast blocks 15 sec? I am learning now coins work Smiley And if I wanted to add peers manually is there some howto handy? I usually use linux and I am sleepy.

Seems pool might come back  soon Wink

Dammit. Yesterday night I calculated that block 17280 would be reached at 11:00 this morning (in about 2 hours) but all that activity has got it going earlier. I missed it :-(

I think that we need to perform the following steps:

1) contest for the real name
2) contest for the best logo
3) send petition to btc-e

 Cheesy

But block size and transaction volume limits should be adjusted before.

But block size and transaction volume limits should be adjusted before. Can you expand on it? I spoke to some folks, if I understand correctly changes in protocol such as block size simply require small changes in client? say main.cpp and so on? Smiley It can be coin that dares to experiment while mining goes Tongue

It's not so simple because there are many other constants which calculated from maxblocksize. We need ~ 64k for maxblocksize at such blocks rate. But it will affect max transaction size, because it's calculated as maxblocksize/5. This should be changed also.

Well, I know the momentum is good right now and of course it would be nice to recycle (parts of) this coin and create a new more thought through one (in fact: anyone can just fork and do so right now).
At least I wouldn't do this, until we have some more novel changes that make the coin solve problems better than other currencies.. also I really like to have some models first that give us hints how the coin could behave in the future or during attack scenarios, .. .

Please include more detailed build instructions for Linux.

Ubuntu server 12.10 - extract from my sysprep script (run by admin)
Code:
# dependencies
sudo apt-get -y install build-essential libssl-dev libdb++-dev libboost-all-dev libminiupnpc-dev

# enable in firewall
if ! sudo ufw status | fgrep --silent 9030
then
  sudo ufw allow 9030
fi

Extract from installation script (run under user account which is going to run the daemon)
Code:
#!/bin/bash

# smallchange installation
# intended to be run as the user who will run the service

# get software
if [ ! -d ~/smallchange ]
then
  cd ~
  git clone https://github.com/bfroemel/smallchange.git
  cd smallchange/src
  make -f makefile.unix

update on my experience with the coin so far.  I left my miner going over night and when I woke up I had 8200 confirmed coins.  I thought, okay great.. So I had to do something on my machine and restart it.  I turn my wallet back on and it starts to resync to the network... Now I have a total of 12 coins mined.. and the rest show as not being credited to me.  Why would it show as confirmed and then now take them all away?  I think 15sec blocks might be too quick for the network if you have 1000's of people hitting it with their machines.. Or am I just sounding like I am crazy?

I had scan time set to 1.  Queue 0.  and expiry 1

Hmmm, so, I've been mining just fine for the past few days and now I suddenly have "0" connections, stuck at block: 20, 668


EDIT: Fixed by opening my listening port in iptables. Not sure why it was working before then suddenly stopped working, but whatever, back to mining   Smiley

Not at all.
Seems to me you have been split from the (main)network and mined alone or in a smaller separated sub network. Of course you would confirm your own blocks, but as the hashing power of the separated sub network has been smaller than the main network, your block chain was in the end smaller than the block chain of the main network. Hence by design you lost everything after the split when you resynced.

Splits could have been prevented by a more dense network (i.e., more connections); and some main hubs (well connected nodes announced by dns, instead of the IRC channel).

I think 15sec blocks might be too quick for the network if you have 1000's of people hitting it with their machines..
Up until block 24 180 the block generation rate was much faster than 15 seconds.. at the beginning of the block reward (block 17280) we even sometimes had 2 blocks per second.. only about now we have reached approx. the target block generation rate.
So 15 seconds block rate might work, while I agree that a block rate of only several seconds or even subseconds can't work well with the current design.

So I forked myself Wink

Okay, makes sense.  I will do a complete resync to the main network and put my miner back on it and see what happens.

How do you perform a resync? (noob question). I suffer from the same. TONS of solved and 24 coins in 7 hours.

You COULD go ahead and read the previous reply's to the thread. It was DDOS'd @ 4.5GB/Sek. Wallets/DB are safe and owner is working on getting it up and disbursing coins.

For the non-GUI client:
Optionally, delete ~/.smallchange/peers.dat (contains all previously found peers, but since you're split, they don't help you much) and restart client. Look at ~/.smallchange/debug.log and make sure, that there is something like that:
Code:
IRC :pelican.heliacal.net NOTICE AUTH :*** Looking up your hostname...
IRC :pelican.heliacal.net NOTICE AUTH :*** Couldn't look up your hostname
...
IRC :pelican.heliacal.net 001 u5XG5jmFiYFpABt :Welcome to the LFNet Internet Relay Chat Network u5XG5jmFiYFpABt

Unfortunately, irc.lfnet.org seems to point sometimes to a dead IRC server, hence you might need to try a second time.

To verify your connection status:
Code:
# ./smallchange getinfo
{
    "version" : 60300,
    "protocolversion" : 60001,
    "walletversion" : 60000,
    "balance" : 75.40000000,
    "blocks" : 25617,
    "connections" : 7,
    "proxy" : "",
    "difficulty" : 0.06622092,
    "testnet" : false,
    "keypoololdest" : 1366762258,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "mininput" : 0.00010000,
    "errors" : ""
}
The field 'connections' should be > 0. In case the coin survives the first 2 weeks, I'll setup a domain name entry and a well connected node. Then such issues should not happen anymore.

So it sounds like, the faster the target block time, the faster we need to retarget the difficulty.  I also like reward delay and graduate reward increase idea.

These parameters bounce of each other in interesting ways, but it doesn't seem  like a terribly complicated system to model.  The hard part would be finding the boundaries of the variables.  Things like minimum time required to request and start new work.  minimum latency requirements.  maximum data throughput to a casual users wallet.  That would give us limits on the model, which we could then fine tune to give the performance we want.

...

brain ran off the deep end here for a minute.  this may be completely unrelated, but i'll dump it here anyway, since we have people who actually think in this thread.  bare with me; i'm shooting from the hip here, and the coffee is only starting to kick in.

dynamic difficulty retarget seems a given.  what about dynamic rewards?  it sounds like a terrible idea...  i believe liquidcoin made an attempt at it, but hear me out a sec.  dynamic rewards plus dynamic difficulty would allow you to tune for a specific number of coins a day, regardless of network has rate.  that seems like a reasonable way to control inflation. 

... i had an idea here regarding arbitrage, but I just talked myself out of it.  either way, inflation is one of the critical variables that needs to stay well damped in a fast moving currency.

I think the coin with some changes can really be working fine. Maybe we can form a developers group and make it work nicely this week. I know where to change some parameters like difficulty, etc. Maybe someone more experienced can do more. Smiley And yes make maybe new name and logo as balhazar suggested Smiley

I think that we need to perform the following steps:

1) contest for the real name
2) contest for the best logo
3) send petition to btc-e

lol

Well, I know the momentum is good right now and of course it would be nice to recycle (parts of) this coin and create a new more thought through one (in fact: anyone can just fork and do so right now).
At least I wouldn't do this, until we have some more novel changes that make the coin solve problems better than other currencies.. also I really like to have some models first that give us hints how the coin could behave in the future or during attack scenarios, .. .

But block size and transaction volume limits should be adjusted before.
working on that.

lol... double spend built right into the wallet!
Now that's innovative!!   Grin

I will NEVER ask for any kind of funds up front in a buy/sale of anything on bitcointalk.
