Title: [ANN] Quantumcoin Post by: Lhunephel on June 03, 2013, 08:55:40 AM After playing around some time with the code of Litecoin I'm now finished with my own little blockchain.
* based on the latest version of Litecoin * total of 256 million coins * block maturity after 100 confirmations * block value is cut in half every 256000 blocks * dynamic retarget interval and target timespan The target spacing and the retarget interval depends on the networking hashrate. The maximum target spacing is 240, the minimum target spacing is 120. The maximum retarget interval is 15, the minimum retarget interval is 3. Those parameters results in a maximum target timespan of 3600 and a minimum target timespan of 360. * increasing block value with increasing difficulty The minimum block value is 10 and the maximum block value of 50 will be reached when difficulty reaches appr. 110. The first blocks are already calculated to reach an appropriate starting difficulty (appr. 0.4 at the moment). The sources are available on GitHub (https://github.com/quantumcoin/quantumcoin) and should work on Linux and Windows. I could only test on Linux. A Windows binary is now available at http://www.quantumcoin.org/files/quantumcoin.zip. There is one DNS seed with three nodes available and seeding through IRC is also working. It should not be necessary to manual add nodes. Enjoy. http://quantumcoin.org/img/small.png example quantumcoin.conf: Code: rpcuser=quantumcoinrpc example entry in the pools array of cgminer/bfgminer: Code: { Title: Re: [ANN] Quantumcoin Post by: tytanick on June 03, 2013, 09:02:34 AM but 800 blocks premined ?

Title: Re: [ANN] Quantumcoin Post by: BladeRunner on June 03, 2013, 09:43:04 AM the idea might be a bit nicer than your average copycoin, but releasing out of the blue without windows binaries was not so smart Trying to gain traction with the "leet" who keeps compilers on their boxen. perhaps in some manner to add validity to the release by source only? Title: Re: [ANN] Quantumcoin Post by: Lhunephel on June 03, 2013, 10:36:20 AM To answer a few questions:
* Why Quantum? Why not? It just liked the word. * What's new with QTC? First the block value is addicted to the difficulty. Higher difficulty results in higher block value. Second the target timespan and the retarget interval is addicted to the overall network hashrate. * Why no Windows binaries? I think a source release is sufficient. You can build windows binaries with the included Makefiles. Just install the MinGW Toolchain (including UPnP). I have to do that for every alternative coin because they usually don't ship Linux binaries. * Why are there premined blocks? Just to have a higher starting difficulty without mining a genesis block with a high difficulty. Sure, it's not the number of the blocks determining the difficulty, but the difficulty just adapts slowly over time.

Will have a look at the MinGW tool chain. Because, it takes some time to install mingw, takes a lot of drive space. Usually have troubles getting various releases to compile. its just a bit pain in the A**. That being said the same reasons you didnt feel the need to include the binary release it was just too big of pain in the A** for you too. Thats pretty telling dude, if you dont care enough to include a windows binary for 80% of the users out here, Most of which know NOTHING of how mingw or how to use make. It tells us all that you have very little interest in making this coin go very far.

First I wanted to see if everything behaves like expected and second I don't wanted a high difficulty for the genesis block. Searching a genesis block with lower difficulty is much more fun. Really, I don't understand the problem. The first blocks were mined at the lowest block value only to increase the difficulty. The block value will soon increase. When you set the starting difficulty too low everyone cries "the orphans, the orphans". But if you announce the block chain with a higher difficulty it is also not good. Title: Re: [ANN] Quantumcoin Post by: Lhunephel on June 04, 2013, 05:14:12 AM And sorry about the Windows binaries. But I think that's a problem of the community. I'm not a Windows user, I don't have testing systems. If there are really 90% users using Windows there should be enough users able to compile the sources on Windows (without an high effort). I think it's the fairest way to release only the sources.
Anyway, it doesn't matter in this case. The block chain was announced with a reasonable high difficulty and the block value increases with the difficulty. Also the target time span decreases with higher network hash rate and the retarget interval decreases with higher network hash rate. So there is no disadvantage when you mine this coin days, weeks or months after the announcement. Title: Re: [ANN] Quantumcoin Post by: Lhunephel on June 04, 2013, 05:25:19 AM This is a list of the block values until difficulty 20. The formula is rather simple: nSubsidy = ((0.2 * exp(nDifficulty / 250) / pow(nDifficulty, -0.25)) * 50), but working. The minimum block value is 10, the maximum block value is 50 (will be reached with difficulty 110).
