Title: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [*update now*] Post by: lightenup on April 21, 2013, 05:20:59 PM 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! ;) *) 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 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 Title: Re: > SmallChange 'new' Litecoin based [15 seconds blocks] [scrypt] [research coin Post by: Balthazar on April 21, 2013, 05:24:31 PM It will be dead-by-design, if you leave difficulty adjustment algorithm without changes.

Thanks for the honest advice -- I expected that my chosen coin parameters could break stuff ;)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...

Title: Re: > SmallChange 'new' Litecoin based [15 seconds blocks] [scrypt] [research coin Post by: Balthazar on April 21, 2013, 06:07:29 PM I understand, but at least the sampling interval increase would be helpful. ::)
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. Title: Re: > SmallChange 'new' Litecoin based [15 seconds blocks] [scrypt] [research coin Post by: Rawted on April 21, 2013, 06:12:09 PM 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.

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.

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: sdp on April 22, 2013, 12:56:13 PM 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? ???

You mean the code in src/checkpoints.cpp ? I couldn't enable checkpoint checking before there is something to check ;)Anyway: thanks for reviewing the code. Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: Anon136 on April 22, 2013, 04:39:12 PM 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.

Also the difficulty adjustment algorithm probably requires a complete redesign... aw that's going to be great fun! 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.

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: Anon136 on April 23, 2013, 06:53:32 PM 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.

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 :) So pool really does not offer alot when coin just starts. Your thoughts are welcome :) Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: paul21 on April 24, 2013, 03:28:11 AM 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)

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? Lol I mined a bit. 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.Here is the question, we discussed it before with some folks.

Quote from: Anon136 well if we had an honest monopolist than 10 second blocks could work ok =P. [..] Nice disucssion! I'll come back to that.Quote from: wmikrut I don't do 51's.... count my hash power as initial 'security' 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.Quote from: Cheshyr 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.Quote 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.Quote from: RichG Please include more detailed build instructions for Linux. Done.

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? :) It can be coin that dares to experiment while mining goes :P Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: Balthazar on April 24, 2013, 09:26:38 AM 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.

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..

Queue 0. and expiry 1 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). Quote 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.

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

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. Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: alex_fun on April 24, 2013, 03:46:10 PM I think the coin with some changes can really be working fine.

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: Otaci on April 25, 2013, 09:54:02 PM 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/ (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.

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 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. -rescan is actually quite useless. -reindex is a lot better. rescan just looks through everything again for transactions. -reindex redownloads the blockchain.

If not, say thank you and leave it. scam: "oh! it works just fine, I never ever thought it would, now its no longer an experiment." I'd like to comment on the experiment part and the purpose of SmallChange: The coin is research only, I explicitly (from the start) expressed that and included some red text in the first post of this thread. It's going to stay 'research only' unless someone announces it as a real currency (and then its up to the people using it or not). In case I am the one to announce*), there is going to be a fresh start; I certainly will not do this in the next couple of months (years?) because I am very new 'to the scene' and still like to play around + 'get a feeling' for this first. I want to add novelty and solve *real* problems instead of just pseudo-managing another rebranded altcoin. I plan to update the codebase a few times a month and welcome any helpful/useful contribution (which will be duly credited of course; ah yes, and it must survive my(/the community's?) criticism). Other than that: I wanted to devalue some of the "weaker" coin spinoffs by showing that really any (idiot? :) ) can release a cryptocurrency nowadays. Also a few people expressed that the coin has been/is helpful to let them setup/try out services (e.g., mining pools) and get started with the inner details of cryptocurrencies. So from my part: please expect something slow boiling, maybe useful but probably not. If you have extra resources or have fun experimenting with an alive block chain where you might end up credited as a hashing power contributor or even author: please join - otherwise wait until this is over or becomes something good. btw: the hash rate is currently ridiculously high. Please mine LTCs or something else ;) .. a few KHashes/s are currently (where we are still very close to the original Litecoin code base) really enough... *) what others do with the codebase or blockchain is already out of my hands -- never has been in my hands ;) Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: Otaci on April 26, 2013, 07:31:14 PM Ota's Experimental SmallChange Pool - http://sc.cascharia.com/ (http://sc.cascharia.com/) I've taken it offline.

I've learnt a lot from it and have some comments which I will pass on to the community in a following post. I'm sorry the pool failed to reward you with the coins which it should have done. SmallChange is a research coin and my pool was experimental but I still feel guilty about the rewards. I do not intend to take the code of the pool web site any further so I am not inclined to spend a huge amount of effort in working out how many research coins I owe you. So I am taking a simple approach which will err on the side of generosity. There were a total of 46,565 shares generated (the vast majority by myself). Some of these contributed to a block being produced for the pool, the majority didnt. The pool earned 552 coins. Thats 0.01185440 coins per share. Quadruple it, that's 0.04741760 coins per share. For those accounts which have a payout address configured, I will transfer this amount to the address. For those accounts which dont, I have put the website back up and if you want them, register a payout address within the next week and I will transfer the coins. I am ignoring all previous payouts. Once again, thank you for trying the pool out.

Well - I am still playing around with difficulty and tx fees. I also left the max block size unchanged for now as I don't see any benefit to reduce it.

How does it work? Each entry is a checkpoint and when the client rescans or downloads the block chain, it verifies it against those entries (i.e., there is no divergence to another illegitimate block chain). Checkpoints ensure that the block chain stays frozen up to the (last) checkpoint. Quote from: ronaldinho_07 it's still in "research-progress",isn't it ?

Is that client still up to date? I might be wrong but I thought you can do it. That you don't need other clients confirmation. That's why also you have a small advantage to mine block n+1 if you mined block n because you have knowledge of this block n before the others (depending on time for network propagation). That was in discussion earlier in the thread, how much somebody with a strong mining power can "take over" and mine all blocks in a row for a while, that's the main reason why you can't reduce block confirmation much less than 15s, and I think one of the major question regarding this coin.Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: noyvpom on May 07, 2013, 12:07:54 PM Someone just sent me 1.234 coins, so I guess I'm on the correct blockchain, and things are working now.

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: ronaldinho_07 on May 08, 2013, 03:26:47 PM - added a few checkpoints for current block chain + reenabled code that does the checkpoint checking By curiosity, what are these checkpoints exactly? How does it work? Each entry is a checkpoint and when the client rescans or downloads the block chain, it verifies it against those entries (i.e., there is no divergence to another illegitimate block chain). Checkpoints ensure that the block chain stays frozen up to the (last) checkpoint. Quote from: ronaldinho_07 it's still in "research-progress",isn't it ?

I admit I could only look at the code briefly, but it appeared that the magic value is not only used in the network protocol.

Does the difficulty play any role, so that if LTC difficulty is larger than SMC one, the "disruption" can only be from LTC to SMC and not the opposite? Or it does not matter? Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [scrypt] Post by: lightenup on May 10, 2013, 08:01:20 PM After some testing and consideration the easiest way to fix is a hard move to a new network magic number which does not invalidate the disk stored block chain, but will only invalidate the disk stored peer information. This requires an update and the transition will most likely result in some loss of coins because the network will be split into two partitions until all have updated their client.
As more and more hashing power moves from the older version to the newer, the block chain of the newer version will at some point grow faster than the block chain of the older version which is going to be overtaken (but up to that point each time 'overwritten' when a client moves from the older to the newer version). Anyone mining on the lower chain looses out (which is going to be first on the newer version, but then on the older). Benefits to move to the newer version are that network connectivity will get better again. Quote from: binaryFate What would prevent us to do the opposite, that is, to build on purpose a longer chain than LTC, so LTC nodes would start to accept it? Our hashing power compared to the LTC network or most other LTC based networks is low; hence our difficulty is also low and even if we achieve at some point a higher block chain than other networks, our block chain is most likely incompatible with other networks difficulty requirements.Does the difficulty play any role, so that if LTC difficulty is larger than SMC one, the "disruption" can only be from LTC to SMC and not the opposite? Or it does not matter? Also - we have a different genesis block and our blockchain is also not going to fulfill checkpoint requirements of other networks. Anyway: that's not so much the problem here. Part of the problem is that our network is very very small compared to others and unfortunately, someone seeded a few 1000 (~4000) node ips from a different network. Now the network code tries to establish connections to those other foreign nodes and because of a mistake on my part (didn't use a unique network magic number) those connections are successful up to the point where it tries to catch up with the block chain. All in all it takes a long time until it is found out that the block chains are incompatible, thus it Quote from: Bitcoin Megastore takes shitload of time to find valid nodes. It also takes shitload of time for SMC wallet to realise some node is not SMC wallet, even though that other node is constantly doing "sinister" deeds. btw: IRC is not down, but the IRC nodes are only partly considered for connections.

Finally at point t3, n3 also moves to the newer version, but his mining efforts are lost, because n0 and n1 naturally could build a higher block chain with their hashing power majority.

I honestly don't understand these extreme reactions, up to using words such as "retard" which is inapropriate to say the least. It would be understandable if the SMC project was claiming to be the ultimate alt-coin. But it was the opposite, from the very beginning the dev made it clear that it was meant to be research, that he and whoever willing to play with sources would experiment the implementation side, and that anybody willing to mine it would also be part of an experimental thing. I don't care if something is hard-forked, because thanks to this I learned what "hard-fork" means. I don't care if thousands of new nodes messed up with the p2p network, because thanks to this I learned about the magic bytes hand-shake stuff. Most important, I don't care if people are leaving the boat complaining, because they leave with such stupid complains, they are not bringing anything useful for me to learn on this thread. There are so many alt-coins launched every days, if not hours, that are just shitty scams. These are the ones which must be denigrated. SMC from the very beginning took the opposite direction and tried to do something useful.

Can we found out which of the "new" or "old" block chain we're mining when we find blocks? If the older version overwrites the newer, REORGANIZE messages with high disconnected blocks should appear in your debug.log. Another indicator is that you lose mined coins. If the newer version overwrites the older, then everything stays 'normal'.Each time someone from the old version updates and joins the new version, he or she resynchronizes the two block chains. If the older has been faster, the newer is overwritten (from the split/fork point). -> At most the mining efforts starting from the update are lost. Currently, the network hashing power of the newer version is rather large (about 6 MHashes/sec), we are at block height 100 941. -- now is a good time to update (see https://bitcointalk.org/index.php?topic=182430.msg2102353#msg2102353).

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [*update now*] Post by: lightenup on May 22, 2013, 06:31:08 PM Here the data up until about 2 days ago:
https://github.com/bfroemel/smallchange/blob/master/data/20130520/blockstat.dat?raw=true It includes extinct blocks -- at least the ones I could obtain. and some visualizations: https://github.com/bfroemel/smallchange/blob/master/data/20130520/hashratevsdiff.pdf?raw=true https://github.com/bfroemel/smallchange/blob/master/data/20130520/blockrate.pdf?raw=true For both plots, I use the block height as 'time' and not real time. Blockrate is only up until block 90 000 (before the switch to the new network magic). Most interesting are the startup phase (16 000 to 40 0000) and the network fragmentation caused by the network collision (starting at around 92 000) until it is resolved by the switch to the new network magic number (~ 104 000). As can seen in the blockrate plot, difficulty adjustment has room for some optimization. Each time difficulty went down, people threw their hashing power in and mined as long as difficulty remained low.. causing the diff oscillation of about 72 hours - that's about 2 times the time that is considered for the current difficulty adjustment algorithm. Interestingly (not visible in the graphs, but the raw data), the extinct/stale block rate (blocks that divert from the main chain) is rather low - even during the times where several blocks were found within the same second/timestamp. That rate peaked during the network collision period. Quote from: defaced Also did you change the max blocksize at all, and if so, what is one of the major things you have noticed? see my argument here: https://bitcointalk.org/index.php?topic=182430.msg2040013#msg2040013 which basically is: max blocksize remained unchanged, because it only restricts the number of transactions per block. Smallchange pursued the goal to be a microtransaction currency and that means we'd need to support lots of tps. Overall, the network hash rate has peaked during the period where block rewards started (about 30 MHashes/sec). We are currently at block 136 436 and the current estimated network hashing power has stagnated to 0.25 MHashes/sec which means that this little experiment is basically at its end ;) -> It's been fun, I've learned a lot - thanks for all. I might work on difficulty adjustment in the midterm future - if anyone wants to try out things with what I started, I am always happy to review/comment on them or take code contributions. \edit: small error in the blockrate plot: it's not blocks per second, but diff time between two blocks -> should have applied f(x)=1/x .

Thanks a lot for the feedback :) In your opinion, the oscillations are due to a too small hashing network (thus varying a lot when people join or quit it), or are inherent to such a very short block confirmation target, or something else? Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [*update now*] Post by: Balthazar on May 25, 2013, 12:15:41 PM Don't forget that high blocksize provides an additional latency. If you are maintaining a fast blockchain (like SMC), you should minimize blockchain syncronization latency. Latency could cause chain forks, which will neutralize all benefits of fast chain, because REORGANIZE will be called too frequently. That's why blocksize limit should be adjusted.

Title: Re: SmallChange [research-only] [Litecoin based] [15 seconds blocks] [*update now*] Post by: lightenup on May 28, 2013, 11:40:44 AM In your opinion, the oscillations are due to a too small hashing network (thus varying a lot when people join or quit it), or are inherent to such a very short block confirmation target, or something else? I think its the first possible cause you suspected: imo, the oscillation mainly occurred because of the small user base where especially users with relatively high hashing power only contributed when difficulty was low.Further, I think that problem can be mitigated technically by a more advanced diff/block reward adjustment (or a higher (competing) user base). Don't forget that high blocksize provides an additional latency. If you are maintaining a fast blockchain (like SMC), you should minimize blockchain syncronization latency. Latency could cause chain forks, which will neutralize all benefits of fast chain, because REORGANIZE will be called too frequently. That's why blocksize limit should be adjusted. True, but it might be better to further increase the max block size and also increase the target rate a bit if latencies become a problem.. but that's probably better evaluated in a faithful model of smallchange (e.g., Matlab).Smallchange's main goal is to provide a high transaction per second (tps) rate to be feasible for micro transactions.
