Hmm that is weird, presumably there must be a working version of it someplace then, I wonder where they hide it.

I have proposed an auxiliary transaction feature (https://bitcointalk.org/index.php?topic=113615.0) with ppcoin to natively facilitate distributed storage of key-value. Auxiliary transactions/blocks are deleted after expiration thus addressing the block chain bloat issue with a namecoin/bitcoin solution.

I plan to start implementing this feature in a couple of months but I would love to hear comments as to what app writers would need (such as your proposed exchange). If I got time I might consider doing a simple web-of-trust app prototype to test out the auxiliary transaction feature as well.

I miss the Realsolid and his schizophrenia. Hope he does well in mental hospital.

You could definitely do a withholding attack, but why on earth would you do it? It doesn't benefit you, you just make the pool poorer that you mine with, and unless you have ultramegahashes to waste, your effect of withholding a block solve will be insignificant to the final outcome. There is nothing suspect about not returning a share from any work gathered from a pool, and a block solve is no different to returning a share. There is no way to check if a miner is returning all the shares it's "supposed to" as there is no such metric. Pools never send the same work item out to two different miners, so they'd have to have some reason to suspect this is the case, so unless you mine with a pool and after 10x difficulty submission of shares you still haven't sent a block solve, then they'd have to start investigating. Even then, bad luck alone is enough for even 10x difficulty and no block solve to occur. So at current difficulty, for example, a pool operator would have to get suspicious only after you had sent 30 million shares without a block solve. That's a heck of a lot of work you're doing just to withhold one block. So unless you personally have something like >1% of the total bitcoin network hashrate, this is a futile exercise.

On the other hand, if you get enough people running the same malicious mining software you could achieve this. But to what end? It doesn't benefit you directly in any way. Luckily all the source code for my mining software (along with most other mining software) is free and open and anyone can audit it to ensure it's not doing this.

Someone mentioned in a PPCoin thread they were having trouble compiling a copy of coiledcoind.

I don't know which one I am using, when I do "git pull" to see where I pull it from I get asked for username and password, so I think maybe whatever github repo I had been pulling it from is no longer up there or something.

I have archived the copy I am using, I would have added a checkpoint but my debug.log only shows some aux proofs of work found no normal ones and I am not sure if the aux ones would work as checkpoints.

Also, the thing totally lacks any checkpoints, the whole checkpoints array contents are commented out.

I have created a directory for CoiLedCoin at https://sourceforge.net/projects/galacticmilieu/files/

CLC source from: https://github.com/Tittiez/coiledcoin <-- any other source?
GRP: success -> 2 connections lol

another question, whats this: http://sourceforge.net/projects/galacticmilieu/files/RUCoin/

What's this to do with ppcoin? I see "coiledcoin"?

Yes, it is because they can be merged mined that I mine them. I wanted to see how many chains one could merged-mine at once. I wish there were more but most moved to Open Transactions because miners turned out to be insanely hostile to merged mining. GRouPcoin is the weather-vane they watch to see if maybe one can survive as a blockchain despite the irrational hostility, though so far it seems the way to do so is to remain obscure...

(Notice for example no-one is bothering to attack BBQcoin anymore either as they think they already killed it.)

-MarkM-

GRouPcoin definitely isn't, however I do not know of any exchanges supporting coiledcoin, I have not added it to my Open Transactions server yet for example. GRouPcoin though has always been around, it is what all the chains that moved away from chain format due to threats of attacks on their chains have been watching to help them figure out if/when moving back to being actual chains will be practical.

Bitcoin was "dead" too once upon a time. Have you no faith in the general concept or what?

Basically the way "early adopters" do so well i nthe long run is they do not give up on "experiments" that "popular wisdom" claims are doomed...

On linux:
libcurl4-openssl-dev                   7.22.0-3ubuntu4
openssl                                1.0.1-4ubuntu5.5

On windows - I think the executable is statically linked with SSL? It's the latest version of oclvanityminer64

kalleguld.bit => {"NS1":"259.8.7.64", "BTC":"1CRv5oXm8AY2RtRLVAsXfnLsU12BmArtn5"}

GRouPcoin and CoiLedCoin.

You may do so to hurt the pool but you will never profit from doing this. Satisfied?

It does not support merged mining so to mine it would subtract from mining seven other chains.

But maybe when it is seven times as valuable than the average maybe it will start to look worthwhile to say "to hell with all the other chains such as bitcoins and namecoins and devcoins and so on, PPC is more profitable".

However there are many other chains waiting to see if merged mining is really practical so maybe instead of switching to PPC when it becomes "more profitable" adding more chains to the merged mining lineup might need to be considered too as maybe adding more of them (some look like they might even catch up with bitcoin in value) might be even more profitable...

I neglected to mention that these two figures are from the SAME MACHINE - dual booted between windows 7 and Ubuntu 12.04. So, same video card, same motherboard, etc.

thank you K1773R ! but when i try to run it, it doesnt start and hangs my ssh
so i tried to compile it on my own. after a few errors and searching i managed to geht a bitcoind file. renamed it to devcoind... when i try to start i get this error message:


edit: ok i see this in my .devcoin/db.log


maybe i get this because i am running it on a virtual server?

I did look at how p2pool works.  That's why it took me a day before responding instead of just pulling BS out of nowhere, because p2pool piqued my interest.

There is a key difference between SatoshiDice, which is an application of bitcoin that pays transaction fees, and p2pool, which is a miner that is paid transaction fees and generates coins.  Now granted I did not know about SatoshiDice when posting the above statement, but this is the rationale behind my statement when looking at it purely from a miner perspective:

With p2pool, each block found has an extra set of addresses to distribute the block to the peers.  With a centralized pool or solo miner, there is only one address to reward the block reward and fees to.  So if mining was only done with p2pool and no centralized pools or solo miners, then every block found would have that extra set of addresses, and the blockchain would be much larger.

Granted right now, it could be 50-100 addresses every 4-20 hours (I didn't look into the numbers, but that is what you said).  But my thought process is if p2pool finds every block, difficulty of main-net is 1 block every 10 minutes, difficulty of p2pool-net is 1 block every 10 seconds.  That means average work for a block is 60, and so each main-net block has up to 180 unique addresses to pay to.  That is 3600 bytes just in the addresses compared to 20 bytes, with 1400 more bytes to represent the actual bitcoin amount to send to each versus 8 bytes.  That is over half a megabyte extra every day regardless of any transactions done.

Finally, note I said If you don't care about the payouts and are just mining for fun, then why load the network with more transactions? in my original post.  I like the idea of p2pool much better than centralized pools because it is better for network security.  So I think that half a megabyte every day is worth it for network security considering the size of the rest of the transactions.  But if you don't care about more regular payouts, then solo mining is still better for the network (both in terms of security and blockchain size)

If you don't care about the payouts and are just mining for fun, then why load the network with more transactions?
