I have recently read something about a capt coin with inital distribution through solving captchas (I would call it proof of human).
I think that this is a good idea, but I dont trust it.
The best way for the inital distribution of the coins is for me the proof of human.
The problem is, how to make it fully trustworthy?
The initial distribution should also be a long term process and not like 2 months or something.

ppc is probably the worst of the lot.  Why? it uses a different pos algorithm to that of the likes of nxt, which is also different to that of the likes of blackcoin. in peercoin, as far as i know they use checkpoints created by developers which is effectively the devs enforcing nodes to only download the version of the blockchain that is deemed to be "the correct chain". by rights, in a decentralized system it should be the nodes that decide, without human intervention of any kind, which chain is the correct one through consensus rather than devs enforcing this with checkpoints. i admit i havnt researched peercoin enough so i may be wrong on certain points but that is my understanding of peercoin however that is enough information for me to know that ppc will never surpass bitcoin. other pos systems dont use this version of pos and also dont have these types of checkpoints. they do have checkpoints(some only temporarily) but they are not centrally controlled as is the case with peercoin. also a slightly better version of bitcoin would never be enough to supplant bitcoin. it needs to be vastly improved upon before it will be surpassed and overcome bitcoins (more powerful than many think) network effect. if i am wrong, please supply some form of explanation as to how i am wrong. if i am id be interested to read how it actually works, its been a long time since i read up on it so perhaps things could have changed since then. I dont trust nxt. The centralised checkpoints in PPC are an issue, I fully agree with that, but as far I know, Sunny King is working on an other solution. I like PPC because: -Its the first PoS implementation, the devs knew what they are doing -There was no IPO, the coins were PoW mined (they still are) -This is a long therm project -Low PoS inflation of 1% -I think that Sunny King is extremely stilled/smart why dont you trust nxt? and there is nothing illegitimate about an ipo, its necessary for distribution seeing as pure pos coins are required to release all coins from the genisis block. the better method is to do what nem did and it has worked out fantastically. they have been working on a solution to the issue for over a year correct? doesnt seem like they are getting very far. i dont doubt their abilities. but their are certainly other very intelligent people in the pos space. its unwise to over look any crypto other than straight clones. hence why i research every new, modified and written from scratch coin i can find and then judge them against the most likely one to overtake bitcoin. its worked out seriously profitable so far so its obviously a good method of finding investments. I dindt really done any research on NXT. I only know, that it is JAVA based and fully PoS. I dont like fully premined PoS coins, because you cant really tell what happens to the coins. With initial PoW mining you can check how every single coin has been created. I of course know, that every NXT was mined with the genesis block, but the inital distribution is kinda untrustworthy (for me). Also: What happens with the BTC that the NXT developer has gotten from the IPO? |

I am betting on PPC.
Its a improved version of Bitcoin.
I hope that PoS will stop this stupid hashrate race.
that statement makes no sense..? pos doesnt have a hashrate? :/ Proof of stake doesnt rely on hashrate, it relies on your wallet balance. You dont need powerfull asics to solve a PoS block, a normal computer fully sufficient. Also: A PPC PoW hashrate race is absurd, because the PPC PoW reward decreases with the increase of PoW difficulty. |

It is also a bad idea of swisscex to accept Grain deposits after only 6 confirmations.
Missed this initially. It's their business and their risks. If they see it affordable then let it be. I can send you my wallet with all Tx, if it helps you to analyze with issue.
I just wonder, if it works for 2h, would it also work for a day or a week or a month?
The main problem behind Grain is that there is no hash power behind it.
There is no need to send your wallet. Works what? No PoW blocks for 2 hours? Or something else? If the former one, I already explained you: there were no miners active during that time. According to my observations we have only two or three people PoW mining it. And they do not mine it 24h a day. I have only 1 CPU miner running to collect the blocks when there is no power at all - just to give an opportunity to other people to mine. With "works" in mean that the blockchain accepts blocks with future timestamps. |

 This is why I have dumped everything. I was just testing some stuff, but you could time warp the shit out off this chain if you wanted (I didnt, I have only mined 2h in the future without forking the chain). This 2h time change has fucked up the diffculty for 2 hours. You could time warp and double spend as much as you wanted (which I didnt). PoW should be removed, its only a weak point with this low block rewards. "netmhashps" : 77.80505571 nice  Edit: now its all gone  "netmhashps" : 127.60631041 Hold on ... It's still breathing and has a weak pulse ... This is probably someone else doing the same shit. Really? Could you elaborate, please, the complete scenario. After reading stuff about BCX, I was curious how will the Grain blockchain deal with blocks that have a faked timestamp, so I have run a test. I have changed the system clock time on my miner 2 hours into the future and started mining. The network has accepted my blocks and I have also solved PoS blocks with a faked timestamp. I have tested this a second time without a PoS block being solved and the network has rejected my PoW blocks. Normally I get 66-75% stales/invalids, but with the faked timestamp I have got only 40-50%. The PoW difficulty was also lowering! After restoring the normal time I could still mine with a low difficulty for a short time, but then the difficutly has raised without PoW blocks being solved. The difficulty was so high, that I could not solve any (or almost none, I cant remember) PoW blocks until 2 hours since my last block with a fake timestamp have passed. My client also didnt solve any PoS blocks. I cant tell how exacly the network did behave during this 2 hours, because I had only one client running, but I have noticed a very big interval between the blocks. I can remember that the highest interval between block (according to my client) was over 10 minutes (maybe even 20). After the 2 hours, my client have solved a shitload of PoS blocks instantly and the difficulty was back to normal. I could made a copy of the chain and do the above and mine faster than the network. I could also play with the timestamps on my private copy of the chain and I would definitely solve the blocks faster than PoW and PoS of the network combined. It is also a bad idea of swisscex to accept Grain deposits after only 6 confirmations. |

BCX why not attack moneroman88 instead of XMR? No I'm serious. Couldn't you make his head explode or something if you inject enough hash-power?
I'm confident we can easily figure out how to brute-force his head. There must be so many flaws there it shouldn't be too hard finding a plug and then...unleash the flow... making his brain crash, rollbacked to infancy, forked to complete memory-loop, or even maybe steal his soul with a spirit-killer algorithm.
That would be something. There, for real, you would be a hero. XMR is not a proper prize.
I would 51% his brain but it is a null block chain! ~BCX~ Did you already started the attack? |

Well how about you make a poll?

I figure I've got a couple of days to learn how and set something up.
I've never mined a damn thing...don't know anything about it. Can I mine CPU? Can I use Amazon ec2? How to set that up? I will find some reading on it tomorrow night, but if anybody can point me to shortcuts, PM me or post here.
My experience, best XMR GPU miner is
Claymore's CryptoNote GPU Miner v7.0. 5% mining fee but fastest optimization for my AMD cards. Best CPU miner is Yam's M7v minerYam's is 1% mining fee and tailored to CPU type. You will need to know your CPU micro-architecture so that you can download the proper Yam build for your CPU. He also has a good generic build for Non AES_NI CPU's but it is a bit slower as are ALL non AES_NI miners. See http://www.cpu-world.com/ to reference your CPU micro-architecture. Yam's was a little faster than wolf's to begin with, but after enabling "hugepage capability it really took off. Wait what? Nowadays you have to pay fee for using a mining software? Wow! |

EDIT: Maybe you could discuss the fix with one of the other core members (or rpietila), I think most of them appreciate what you're doing here.
None of them take me seriously. I am tired of this shit. You are missing the part where I spent hours (and little sleep) with you going over your work on Sybil attacks and the part (which I posted several hours ago) where I said that I thought you had improved on our work. Very odd. If you want to offer assistance, it is welcome. If you don't want to help, don't. Either way we could do with a little less drama. I rather fancy the idea of publishing the sender of (most) every ring signature on the block chain instead at a future date of my choosing. I warned you don't fuck with me. I will make sure BBR has the mitigation ready assuming they are still cooperative with me and they don't give my mitigation to XMR. You are not dealing with BCX any more. You are dealing with me. Capice. I didn't saw that coming. This thread is gold. |

I have nothing to do with Monero and I dont want to, but all this drama is pure entertainment.
I wonder if BCX is also Fontas.

he may have sent the PM to multiple people...
Correct. Everyone calm down. I am not even 100% sure if the developers haven't already thought of it and have mitigation already in place. Relax while we work through it. I doubt it will take a long time. Why bother selling the exploit if you could use it whilst having a short position in Monero? Or better yet, prove it and steal all the funds, you'll likely make off with far more than 100 bitcoin before the exchanges shut down. Maybe he doesnt have the resources to use this exploit. |

"netmhashps" : 77.80505571 nice Edit: now its all gone |

Nice to see grain still active. I haven't opened my wallet in a long time.
Now it actualy works pretty well, but most people just no longer care. |
