[ANN] Quantumcoin

[Lhunephel]

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.

That's standard

What is the matter of this coin?

[billionaire]

I will only mine this coin if Scott Bakula designed it. I'm going to guess it was Hazard, though.....and I'm pretty sure hes not Scott Bakula.

Difficulty is based on hashing power, not on block count 

[sumantso]

I may or may not mine it.

[jackjack]

Why 'quantum' ?

[JimmyFL]

Why 'quantum' ?

Cause it sounds special?

the idea might be a bit nicer than your average copycoin, but releasing out of the blue without windows binaries was not so smart

[blastbob]

First time i had to do just to "make" on a coin

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?

[Lhunephel]

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.

No windows is just dumb. 90% of users ( like me ) don't have the skills to compile.

Good luck dev!
