[PRE-ANN][BDC]The birth of BLACK DRAGON COIN: unique scrypt-jane fantasy coin

[hometester]

Sounds interesting

[Amph]

can we know at least the week/months in which this will be launched?

[Cloudpost]

Launch will be really soon (not today though)! I'm making a video guide for solomining/ mining now
Scheme that will describe the innovate reward system is almost ready too!

I will edit the first post with updated\changed information. I rewrote the text and improved\updated description.

[bigtimespaghetti]

Nice artwork, will be interested to see how this progresses!

First post updated

Here's the preview of our first wallpaper art (also used as a splashscreen for wallet), it will be available in following resolutions:

Standard/4:3 : 1024x768 1280x1024 1600x1200
Widescreen/16:10 : 1440x900 1920x1200 2560x1600
HD/16:9: 1920x1080 2560x1440



Innovation rewards explanation table & mining guide soon!

First post updated with the innovate bonus rewards system explanation

[ManeBjorn]

I want those pictures this is awesome.
I am so looking forward to this coin.  It is so fun before launch even.

I'm looking forward to this one for sure...

Thanks for kind words guys!




Another nice graphics update.

Our code will look as sexy as visuals, I promise

[ManeBjorn]

Very cool.
I will say my only wish is that we had a solid launch date.
The reason being I could then plan when to switch some hash power to it when it goes live.  I do not always get online when my injury has me in rough shape at times.  I do not want to miss it.

Thanks for kind words guys!

waiting with impatience the launch

I think it's a very neat idea to divide the reward into the current and the next block! (1)

But this random "dice roll" thing (2) might be a bit tricky to implement and could be exploit.
Continuing your line of thought (of reward block separation),
I have much more simple solution to this random thing. Why not use the nonce itself as a "dice roll"?

Take the given nonce of a previous block and use it as a base to calculate the bonus of the block finder (3).
For example if the nonce is 368234 you can calculate by simple module the extra reward (34 coins)!
One can argue that since the nonce is given by the miner, he might choose not to announce his block
if the reward is too low for him (like: 5801103, only 3 coins bonus at the next block).

I would disagree with that argument. Since he already invested the work to find the block,
he can choose to take the basic reward + small bonus, or try to find another block with larger
bonus but risking someone else announcing a block and leave him with nothing.
I would take the money and go…

CoinMiner10, please wait for the release and check our code

You discribed almost the same thing that we implemented, the difference is that we use PoW hash instead of nonce to calculate the bonus

That's nice! 

You know what? how about to eliminate the miner control over the bonus reward altogether?

for example, blocks: 100, 101, 102:
The miner address of block 100 will be rewarded by block 102 based on the nonce / hash of block 101.
(jumping one more block for full obscurity)

The bonus reward will be a complete surprise...

This scheme describes the system we already have for some time (tested etc), we wont change it.

No reason to move rewards 1 block further, nobody will choose to ruin the work that provides 100 coin rewards for the possibility to get a bit higher bonus (you even wrote about it!).

Actually there is a minor (maybe theoretical) issue with this thing, especially when it comes to large (manipulative) pools:

Suppose a large pool finds a block with very little or no bonus reward, the pool can old this block and try
to find another – with better bonus -  block.
when the pool operator  will see another block announced, he could try to announce his "bad" block hoping
for it to catch the other block.
Now, there might be more than one  smart-ass like this, so each time 3-4 blocks will be announced together
forking the blockchain.

There are no transcations without a roll bonus, so it is better (statistically) to announce solved block immediately

You probably right!

That's why I referred to the issue as minor, theoretical one.
Furthermore, by the time the pool is trying to solve a new block for the same transactions
he can announce the block and find a new one...

In spite of this, this (very) little hole is still there... and it's bugging me
