Bitcoin Forum

Dear guest,
Welcome to the Black Dragon Coin thread. Stay awhile and listen!


My name is Nickolas and I'm a fantasy fan. I think fantasy inspires people and brings them new ideas. I witnessed the golden age of computer games (M&M, BG, HoMM, Fallout etc), read many fantasy novels (Ursula K. Le Guin is my favourite), played MTG a lot of time. I'm sure that there are a lot people here with the same world view, people who share similar values as mine. This coin is for you. I will launch a coin that will bring innovations and real benefits for users and will form a strong community.

Why Black Dragon? Dragons are the most powerful and intelligent fantasy creatures. And they love coins, especially gold ones. And I just love dragons. To my mind, the black dragons are the most powerful, wise and dangerous among all dragons. Black Dragon Coin symbolizes the most fascinating aspects of fantasy universe.

Main goal: build a secure cryptocurrency with a blockchain secured by a big number of decentralized GPU farms, become leading Scrypt-Jane coin (Scrypt-Jane is ASIC and CPU botnet resistant), form a strong community and provide excellent development support!




1. Good specs combo:

• Unique innovate reward system: unpredictable dice roll bonuses with critical hits (see the table for explanation)
• Scrypt-Jane with Adaptive N-factor (SHA-3 (keccak512) + ChaCha): cool & secure algo, scrypt ASIC and CPU resistant, flexible N-factor
• Antidump protection: mined coins get confirmed only after 1000 block confirmations, miners will get the mined coins after ~33,3 hours
• Wise block time: with 2 minutes block time the transactions are fast (12 minutes for 6 confirmations), but shorter block time will increase the amount of orphaned blocks and will make the coin easier to attack
• Advanced difficulty retarget: Dark Gravity Wave implemented, lowered block times for 1-1000 blocks to allow solomining and minimum block rewards for blocks 1-200 to avoid instamining
• Smart reward halving: every ~70 days, early miners won't get huge advantage, inflation is limited

Block Distribution: Proof of Work
Algorithm: Scrypt-Jane with Adaptive N-factor  
Block time: 120 Seconds/2 minutes
Difficulty Retarget: own implementation of Dark Gravity Wave
Confirmations: 6 Confirmations per transaction, 1000 confirmations for mined blocks
Block rewards:
Block 1- 200:                            1      + 1d4
Block 200-50,000:                 100 + 1d20 (20 roll is critical hit: block reward doubles and miner gets another 100 bonus coins)
Block 50,000-100,000:        50   + 1d16 (+ 1/20 chance to get double rewards)
Block 100,000-150,000:      30   + 1d8  (+ 1/20 chance to get double rewards[/b])
Block 150,000-200,000:     20   + 1d6  (+ 1/20 chance to get double rewards)
Block 200,000+:                    10   + 1d4  (+ 1/20 chance to get double rewards)
Premine: 1.5 % of 1 year mining period for coin development and support

Explanation of a reward system: See picture

Approximate number of coins for the first year and for the next years of mining:
First year   ~ 14,571,761 bdc
next years   ~ 3,258,720 bdc a year
Approximately 720 blocks a day. (1440 mins a day, 7200 blocks = 10 days, 50k blocks (block halving interval) = ~70 days)[/font]

2. Fantasy coin philosophy:

• Rpg elements for rewards & overall fantasy orientation
• A beautiful fantasy art (desktop wallpaper) every week and more surprises by 2 pro artists from our team
• Fantasy art (dragon themed) and short story contests every month
• Community brainstorming

3. Development plan:


Short term (1-2 weeks)

• block explorer
• beautiful site with background art
• alternative coin logo with asian dragon
• custom fantasy wallet design
• trading on poloniex, start mintpal voting

   
Middle term (3-6 weeks)

• adding more functionality to the wallet: BDC exchange price etc
• online game cd-key shop that will accept BDC & more merchant adoption
• major exchange: Mintpal
• scrypt/SHA-256 multipool for BDC support
• manufacture T-shirts with best BDC arts

Long term (8-36 weeks)

• custom BDC wallet (multibit-like)
• online crowd funding service that will accept BDC to support different fantasy projects (such as computer games/table games/ccg)
• computer game & other fantasy projects that will use BDC
• manufacture more items with BDC arts

Ninja launch based on when all aspects of BDC are ready:

• I will post wallet download links with password protected archives and virustotal link (to prove that the wallet is clean), conf settings and after 10 minutes I will post the passwords on forum/Twitter/Facebook
• I will post miner links (ATI and NVIDIA) + some basic settings
• I will make a detailed step-by-step video windows solomining guide
• I will launch the coin when more users are online (Europe evening time)
• Blocks 1-200 will have minimum rewards: 1+1d4 to avoid instamining
• 1-1000 blocks will have reduced block time to allow solomining (launch party)
• Official pool with random rewards support is ready, it will be opened when it will become difficult to solomine
• I will post big bounty list & pool/exchanges politics/requirement and will start a smart giveaway

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

looks great.hople better.

Awesome  ;D

Please give exact instructions on how to mine your coin with various mining methods. (GPU/CPU)

cool visuals 4 sure

WOW! A beautiful coin! :)

When will be the launch though?

Wow man, such hypocrisy.

Few posts below you were "No thank you" to a similar coin, and encourage this one?

That makes me feel better, that was me, shot down in flames. I'll be back with some tartan wallpaper and some animated gifs shortly.

good !

good coin >:(

I respect the ninja launch idea but can you give us a window of a time when it might happen?

Great artwork, specification and big + for launch part i'm in.
Cloudpost ... BDC it will be the best cryptocurrency i'm with you!

Nice logo and technical issues.

cute DRAGON ;D

The artwork reminds me of HoMM. I'll mine just because of that.  :D
Also, it would be nice if you could at least post the launch date, so we know to keep an eye out.

I'm in  ;D

Awesome 

+1

Thanks for the kind words guys!


It will be a GPU coin, scrypt-ASIC resistant (custom N-factor). I believe that ASIC resistant coins will be very important soon because of scrypt-ASIC mass production (that will happen soon or is happening right now).


I cannot give you approximate day or time because it will ruin the concept of ninja launch. As I stated in the opening post, I will launch the coin by making a forum post with password protected wallets/conf settings/miner link with the popular gpu settings/detailed solo mining guide and release the passwords for wallets after 5-10 minutes when people will be prepared to mine. I think it will be Europe evening time when the most forum members are awake/online.


;)

i'm in for NINJAS!

looks nice.

Nice coin, love the D&D theme.

+1

awesome coin. Love to see coin devs thinking outside the box like this. Will definitely support.

looks great

Hmmmm

If you really wanted a fair launch you would make the first 1000 or 2000 blocks low reward if doing a ninja launch.

100 blocks at very low diff will pass in 1 min or less. At the normal low starting dif blocks come in sometimes 10 per second.


Ninja launches give the dev and friends max instamining opportunity.


Also i know several HUGE farm owners run scripts that monitor these ann threads so they they are alerted as soon as a ninja launch starts.

Of course most huge farms only mine coins they think will bring them a big profit so they don't bother with every ninja launch.




Also what is the total minting for this coin??

shiny. ;D i'll mine it cus why not.

Deathwing coin!... I will get some...just because its dragons   ;D

https://i.imgur.com/crH6FUB.jpg

Nice idea. Will fight for some coins.

Nice coin/logo and who didn't like dragons when growing up?

Looks like you spent some time doing this and put allot of thought behind it, I like the bonus rewards idea as well with the critical hits...thank goodness its not just a clone of another coin with no innovation.....

Good luck and nice to see some value regarding merchants who will accept BDC..

Very nice logo, and coin concept. I'll definitely take part in this project. :)

tylerderden, kingscrown, MisO69, midnight_rgs, scrototeabaggins, BitRock, zakorus, Cryptosapiens, Hundsstern, Vann, sikman, Wolv, thanks for your support. I'm working hard to release a good coin and I'm glad to get positive feedback.


Well, it's a good comment. I will try to explain my launch concept. I did not post many technical aspects. We will try to start with high NFactor = 10 (or maybe a bit lower), so the gpus will have almost the same scrypt-jane hashrate as on scrypt coins (slightly above on 7970/280x). There will be 2 diff retargets during the first 100 blocks (with minimal rewards), lets say every retarget difficulty will increase by 200% (we didn't set the retarget parameters right now, I think it will be 200-300% max increase for solomining period). So with the max 200% diff growth we will have:

starting: 0.00024414
retarget at block  50: 0.00073242
retarget at block 100: 0.00219726
retarget at block 150: 0.00659178
retarget at block 200: 0.01977534
retarget at block 250: 0.05932602
retarget at block 300: 0.17797806

So as you can see even 200% max diff increase is pretty aggressive. After the launch there will be 10 minutes delay before I will release the passwords so many miners will prepare for mining and I expect that the diff will grow up really fast. It cannot be " I will do some tests and maybe we will set low reward for 1-200 or 1-300 blocks instead of 1-100 variant. I'll do several tests to set the final values.
I'll be glad if you can give some ideas how to make launch better. I also can be wrong somewhere.


The simple notify option works good too, I use and I spotted some ninja launches. Sometimes it doesn't work for me :(
It must be not so fast to switch big farm to solomine scrypt-jane with custom miner settings (not to default scrypt coin). But my main point is that ninja launches provide overall better protection from mega farms than scheduled launches.


DBC will have unlimited mining as dogecoin. I will calculate approximate annual coin volume soon.

Really think you should put a cap ... with a maybe 1-2% yearly inflation once it's hit.

All these coins with billions & billions arent doing so hot...

Hi,

Ok, well since we know more now precise details about the launch this is quite a good way to do it. Since also you have already posted that you will release in the evening also... it is not really a total ninja either.

Good luck with the coin.... I love a bit of fantasy too.... raymond fiest and  g rr martin.... JRRT of course.

Great! Will be launched today :P?

Can't wait for the launch :p

To be honest. It's the only coin I'm really thinking about and waiting for since yesterday. This and I'm also waiting for CryptoMeth sometimes.

1. Guys with big farms rape this coin at start, may be need highter N-factor and make more CPU-frendly coin at start?
2. Where start date?

Hix, did you read the first post? I think about fair start for more than a month and made a concept scheme I'm gonna release and there is some details.

Can you please explain how big farms will rape it? I posted a strategy that IMO will at least provide a little protection from big farms. And if you are worried about big farms, maybe you have a good advice?

Scrypt-jane can be gpu-friendly OR cpu-friendly (at really high n-factor). CPU coin = coin for botnets (you can check cpu-only heavy coin that is being raped by cpu botnets. They mine all coins and dump them. I was mining that coin at the very start of pool mining and one day hashrate just increased from 1.5 gH to 15-20 gh, from 30-50 diff to 600). That's why I'm doing a gpu-only coin that will be protected from scrypt-asics as well.

Will you release the code on github during the launch ?

Yes, of course I will!

I will answer some wuestions and update the opening post with additional detailed info tomorrow :)

Ninja-Launch also known as "how to effectively premine your coin without anyone getting pissy".
At least a pre-announcement everyone starts at the same time. How is that not fair?

It's not fair because the little guy has to compete against the big guy? The big guy has invested more money into mining equipment, they are equally matched in how much capital they have invested.

You are thinking its more fair if the little guy sees the ninja launch and starts mining before the big guy. Well what happens if the big guy sees the ninja launch before the little guy?

Not only does he have more mining power, but the net difficulty is lower and he receives even MORE coin than the little guy.

Wow super fair.

I don't know about ninja launch, but low reward on first 100 blocks is a good idea. - 100 block is too low i think.

The concept of rewarding is funny, and i like it. I will mine.

It's a good question. I'll try to explain why IMO ninja launch is better. I don't need to premine my coin more because the fixed premine is pretty big: I know that I will have to pay artist every week and will have to pay a money prizes for the art contest. And more important, I will work on the cd game online shop and crowd funding service a bit later.

I thought a lot of time about "fair launch concept". I have few statements, I hope they will explain my position:
1. Every launch must include solomining part. It's a short period when early miners have chances to solve blocks in solomining mode. I will do my best to avoid instamining (I'll do a couple of tests to adjust early diff retarget and probably will expand low rewards up to block 200-300).
2. Everybody will have the same chances with my ninja launch: I will make a launch thread and post passwords 10 minutes after, I will start the thread when most users are online (CET evening time. Maybe you have other ideas about good time?)
3. Scheduled launches often have a lot of problems (forum is down, download links doesn't work, launch is delayed, difficulty grows too fast and solomining becomes almost worthless, pools are ddosed) and many people who waited for a long time for that launch are disappointed.

I will do my best to organize as much transparent and smooth launch as possible. Same as with this thread: I made this informative announce post only when I had everything ready (concept, ideas, design, text etc.)

I respect big miners, but it's nothing but business for them. They are the big part of crypto world, but there's not a lot of them with huge gpu farms (at least there will be times more scrypt asics farms soon!). Black Dragon coin will be asic resistant, GPU only coin. Gpu miners are the blood of altcoins, gpu miners are the core of altcoin community, they have time and they wish to improve the coin they support. I need a community of people who share my love to fantasy culture!


Yes, I think that increasing low rewards period to smth like 200-300 blocks. Our team will do some testing soon.

Freenode chat (#blackdragoncoin) opened, I'd love to chat and discuss your ideas there.

Multiple domain names, twitter, facebook accounts registered a long time ago. We're working on site and forum right now.

The 1st epic wallpaper is finished. I'm sure you'll LOVE that beautiful art, I'm using it as a wallpaper right now :) (we have most popular 4:3, 16:10 and 16:9 resoultions available: 1024x768, 1280x1024, 1600x1200, 1440x900,  1920x1200, 2560x1600, 1920x1080, 2560x1440)

I calculated the approximate number of coins for the first year and for the next years of mining:

First year   ~ 14,571,761 bdc
next years ~ 3,258,720 bdc a year

Very interesting concept. Its great to see that someone gave some thought into coin. Good work!

I would love to help you out with web development, forum setup or raising a p2pool node for launch. If you are interested of course ;) My wife would kill me if I don't get involved with fantasy coin, especially with this kind of potential.

If you can, choose a "better" algo : keccak, groestl, qubit etc..
multi-pool doesn't use those, and they are more power efficient than scrypt (normal, N, jane)

If you really preffer scrypt, choose scrypt-N instead of scrypt-jane

Just a question to prepare for the ninja launch:

what miners does this coin use?

You should be able to use any of the Scrypt-Jane miners listed below. Be prepared to reconfigure your settings for it to work with your card though:

Thanks for the reply, if I am able to get microcoin mining smooth I would be well prepared?

Yes, that should work. The dev would need to release the nFactor parameters specific to the coin though. The OP says he will post a guide before the launch.

SCRYPT_CHACHA SCRYPT_KECCAK512 ?
or maybe salsa6420/8 ?

Regarding the premine..  I think the best way to handle this if you absolutely feel you need a premine is to have an escrow holder..  The escrow holder then publicly announces any premine disbursement.  That way we miners can feel secure that you're not pumping and dumping. 

Guys, thanks for your replies. I will post more information about algo and miner a bit later.


You like the concept/ideas but don't like the premine? But the premine is the key to development and promotion and it is also a part of my concept (read my plan in OP). If you plan to support and/or mine Black Dragon coin, you have to agree that I will be the escrow holder of premined coins (note that the % is high, but it's a % of the year volume!). It's all up to you.

Unlike many tricky developers, that say that there is no premine, but in reality they instamine the coin in the beginning, I show everybody the premine and my plan. I don't have an IPO. I have a good launch plan and I'm sure supporters will be happy with the coin progress. Just return to BDC after 1-2-3-4-... weeks after the launch and check how it's going :)

Don't worry, I will post all information at launch (and there will be enough time for you to set everything up before I will post passwords). I will provide a miner as well as solomining guide with correct settings examples :)

https://i.imgur.com/b4gujXP.png

http://bdc.allpoolz.com
- Always 0% mining fees!
- Miner Notifications
- Port 8080 mining
- VARDIFF
- Stratum
- DDoS Protection
- Database off-loading (faster more reliable)
- Ticket support
- US Server

Sounds like fun!  Pool is up.  You can register and get your miners setup.

Could you please update the Getting Started page? It is still for REGULAR SCRIPT MINER.

The info in step 2 are for nscript.

any more updates??

awesome idea!
a bit premine but without IPO.
Any more update?
And when will it lanched?

Right now our team work hard to finish the development.

I hope the forum will be up soon, the registered members will receive an email before the launch (10-15 minutes) to make sure you won't miss it because forum notifications don't work sometimes (at least for me). I will make the launch threads on all major altcoin forums, so you won't miss it :)

awesome

NEW URL! (http://crycoco.de)

X11 is better than scrypt-jane, please think about it.

Cool design. Fantasy themed coins are rare!

X11 is much better  ;D

Will Cudaminer work for this?

I also really like your idea of no exchanges for the first week and the 1000 confirmations for miners. Some good ideas here. I'm a big fantasy nerd myself, so I'll be watching this coin closely for the launch. This looks promising.

When are you going to lauch a coin. In a month or in a week?

are X11 memory intensive somehow, or does it have other properties making it expensive to build ASICs for it?

Yes, cudaminer should work fine for scrypt-jane. I've got nvidia gpu, I will test latest cudaminer before the release.


I read the opinion that it is easier to make an asic for x11. Also x11 is cpu minable, with current situation on cpu coin scene (with extremely low profits) huge botnet can easily jump on the coin. Lower mining temps just indicate that the gpu doesn't work at full power.

I doubt that there will be an asic for scrypt-n or scrypt-jane in near future, because these hash algo have got an option to change N factor easily.

The time X11 asic come to reallity, memory will be so cheaper than now, you will see scrypt-n / or scypt-jane asic too.. It's not an algo matter, but a success matter. If a coin is very succefful and popular, Asic manufacturer will make a product for it. But we talk about millions or billions market cap.
Scrypt-N and scrypt-jane are also gpu resistant.. configuring a mining rig for scrypt-n or scrypt-jane is not always easy. It's not very popular. X11 is. You have also others algo you can use (Groestl for example)

Changing N factor to protect the coin is theorically working, but it make miners to have a lot of Ram too. With scrypt-N with 3 GPU (r9 280x) on EXE or VTC coin for example, you need 4Go of ram (to have full hash power). With 4 or more GPU, you'll need 8Go. If the N factor is higher, you will need 32Go on each rig ?


There is 2 way to be really asic resistant : the ability to change the algo with a fork if an asic is coming, and multi-algo (like Myriadcoin). Myriadcoin is not asic resistant, it use sha256d and scrypt, but also other algos. So, miners with asic can mine it with their own difficulty, and "little miners" like us can too, on actually asic resistant algo, with their own diff (lower).

So, i think the only thing that matter is not asic resistant or not, but coin being popular or not. If you want to succeed, you need your coin to be at least popular. Scrypt-jane and scrypt-n are not and will be less popular with summer coming. Choose your algo wisely, with this in mind.

Your choice of Scrypt-Jane is a good one. X11 is flawed https://litecointalk.org/index.php?topic=18166.msg152706#msg152706 (https://litecointalk.org/index.php?topic=18166.msg152706#msg152706)

I also hear that some people have optimized X11 miners while everyone else is using SGMiner.

X11 is an example. There is some other good (better) algos to use. Groestl got my preference, but there is also blake, fugue, qubit, and not as good but still better : skein, keccak, ink, etc....

It might sound rude, but you need to educate yourself.

You name different algos but you have no clue what's behind them. X11 algo = quark algo + some additions.
Quark algo was really innovate but it was released long time ago: Quark algo =6 unique hashing functions (blake, groestl, blue midnight wish, jh, SHA-3, skein)
Also, there's no INK algo, INK coin used SHAvite-3.

There is no "better" algos. They are just different. I think miners like the algos that are cooler (less heat from gpu and electricity consumption), but lower temps might indicate that the miner program is not optimised and doesn't work at full power. MisO69 mentioned that there might be private x11 miners that provide unfair advantage to some users.

Black dragon coin will be a scrypt-jane, it will use: SHA-3 (keccak512) + chacha.


Personally I like scrypt-jane because it provides huge variance of settings (because of N factor timetable which can be changed easily, much better option than changing the hashfunction of the coin) and cooler mining (10-15 degrees cooler vs scrypt\scryptN mining on gpu core and even more on VRMs).

no offense, i'm not a specialist.

I'm just a miner. And by better, i meant better for our GPU, not better in term of security, function etc..

it's a paralelism "problem", due to the algo (or to the addition of multiple hashing functions)

please don't lunch this coin with out a gpu miner posted. Not only will the ninja lunch help your closed group of people but not giving the public a gpu miner also will increase the amount of the coin you will receive.


seriously. provide everything or the coin will only be a pump and dump.


also please as transparency , give us some details on other coins you and your devs might have participated with?  How strong is your dev team. Do you have any more future goal?

Dev team works hard right now to make the launch the best launch you guys experienced in your miner's lifes. I stated in the 1st post (hope you read the whole post), that I will provide everything: pass protected wallets for mltiple OS, virustotal link, link to radeon/nvidia miner (with examples of settings), .conf file and even a detailed windows solomining guide with pictures. And after 10 minuites we'll release source code + passwords :)

The dev team is good! You can check the code after release and compare with other coins  ;) Also we'll release our first wallpaper and you will see how good is our artist.

I will release a detailed development plan after launch.

I have a banana for ninja lunch about 11 every day.

premine no thanks

for when is plan the ninja lunch ? Hope it will be rather at dinner time...

Please don't do a too ninja launch, it makes people suspicious of dev instamining their own coins....
there are already enough dead scrypt-jane coin... and for some reason scrypt-jane coins tend to die young...

What the hell.
Why are our names almost exactly the same?

Weirdest coincidence ever.

Latest news about coin development:
- innovate rewards system implemented, working great
- we decided to implement Dark Gravity Wave, checked the code, it's much better than KGW. Solomining period (below 1000 blocks) will also use DGW, but with reduced block times (to lower the difficulty to make solomining more successful during solomining period - I'll update the specs on the first post soon)
- coded and testing automatic checkpointing system
- scrypt-jane mining tested with sgminer and cudaminer, everything works perfect
- testing win/linux wallets, will try to have a mac wallet as well on launch
- we'll try to setup and test official pool to guaranty pool mining after block 1000

BDC forum is up and running (need to update subforums descriptions).
http://forum.blackdragoncoin.com/ (http://forum.blackdragoncoin.com/)
Please sign up, there will definitely some advantages for dbc forum users, more information later. I plan to stay away from exchanges and list on poloniex after 1 week, I will offer FREE escrow service for trades on BDC forum.
Twitter/facebook pages registered long time ago too, but I need to fill them with content, it's on my todo list.

https://twitter.com/BlackDragonCoin (https://https://twitter.com/BlackDragonCoin)

BDC team future plans (also to be updated!):   

Weekly/monthly goals:
- beautiful high res desktop wallpaper - every week!
- art contest with money prize - every 1 or 2 months!

First week after release:
- find good and reputable pools to spread the hashrate (at least 3-4 with 30% total hashrate limitation), modify p2p pool code and set p2p pools (bounties will be available on launch)
- actively build a community, focus on BDC forum
- paper wallet
- block explorer
- site with fantasy art elements (might take more time because there is a lot of work for artists/designers)
- custom icons and design for the wallet
- set various bounties: translations, pools etc.
- list on poloniex after 1st week + add dbc/btc ratio straight to the wallet

Bigger goals:
- code a custom wallet (like multibit)
- open the BDC cd-key\code online shop & crowdfunding site

I registered on reddit some time ago, but I cannot create my own subreddit (nothing about that in their faq, looks like they disabled that feature), can somebody help with BDC subreddit?

Forum looks great. Sounds like you have thought this out well. Certainly does not seem like a pump and dump coin, a rare quality these days lol. I will be mining this one when it is ready.

Thanks cbassthefish!

Here's the main links for BDC:

mark me interested

Dev seems really on top of things, I think I'm all in on this one. I can see this one really taking off.

...but WHEN!?

:D

So whats the ETA on coin?

Coin dragon looks like he is dancing the cha-cha-cha.  Im out.

 ;)

Please register on our forum, follow twitter and like BDC facebook page. I will start to fill forum with useful content soon.


Also, can somebody help with subreddit for BDC?

I registered on reddit some time ago, but I cannot create my own subreddit (nothing about that in their faq, looks like they disabled that feature), can somebody help with BDC subreddit?

Looks good to me.
Which sgminer do you use or testing atm?

cgminer also has a scrypt-jane version. Does that one work?

yacminer works well.
So when does it launch ?

I will post mining guide on the forum today or tomorrow, all information will be available there.


Launch will be soon(not today!), need to finish just a few things. Please don't ask about exact day, I cannot tell.
Please register on our forum, follow twitter and like BDC facebook page. I will start to fill forum with useful content soon.


Also, can somebody help with subreddit for BDC?

will you post in advance the parameters for the scrypt-jane miners (unix start time, min and max nfactor) ?

Sure, don't worry  :) I mean that I will post everything needed for mining AND a mining guide in addition :)

Don't tell me you're the guy who donates his coins to the dev teams to support them?
Oh wait. The time your GPUs are working real hard to mine is more expensive than the time, money and hard thinking this coin's devs are putting into. So they deserve nothing, they should do everything for free, so only the hard working miners can benefit from it.
Oh, and of course we demand free support for the rest of their life, otherwise they are scamers, correct?

An honest statement about premine percentage and how it is going to be used (even for sallaries) is better than a coin that dies because the dev has real life issues and can't compensate with development at the same time.
Besides, can you tell me why you mine coins? To support the idea? Because it's fun to pay the electric bill just to watch your cpu/gpu/asic turn into a heater?

It's strange how people believe they deserve it all and the ones who gives them that opportunity deserves nothing...

Devs tend to destroy coins by dumping as soon as an exchange hits.  What would make far more sense would be to create a cryptocoin that sends 99% of the block to the miner and 1% to the dev.  Doesn't DevCoin do something like this, but with a disproportionately large amount going to the devs?

There we go, that is the fix then. Shouldn't be too difficult to code if its already in use. Now the question is who deserves what? Pools take 1-2% or more if they can. Devs should also take a similar amount, but NOT ALL AT ONCE. That is like me going to work for someone and saying that they need to pay me 10 years of salary ahead of time. The next day I decide not to show up because I opened my own business..(made another coin)... this happens often.

So new pre-mine rule, the pre-mine for the dev's fees should go to him as a percentage of each block.
The pre-mine for services such as pools, exchanges should be mined in block 1. THIS IS NO WHERE NEAR 1% only what is fair based on the coin's daily reward generation.
IPO = scam, money for something that isn't worth anything yet.

If you believe me and I will fulfill my promises, this coin will have great support. I'm honest with the premine. I do not hide it and do not make it 0.3% but of 10 years mining period.  I don't do IPO. I aim to have a smooth launch without instamine because I have the premine to continue the support of the coin.

If you do not believe me, just move on, I do not force anybody to mine or to support Dlack Dragon Coin.You can wait 2-4 weeks and see what will happen with the coin.

I have been reading the thread and I am interested in Black Dragon Coin.
You absolutely need to get someone to make a physical coin that can do it justice.  That is an excellent logo.
I am looking forward to the launch.

Coin looks interesting,waiting for the launch

Coin looks really good, will be watching this thread closely. Bookmarked!

I'm working on new infografics with all information about the coin inside.

Right now we're testing official pool.

any indication when you will release it ? (I joined the forum, but there isn't much activity yet)

Nice looking coin! :) Wish you good luck!

Thanks for joining BDC forums!
I will do some articles on our forum soon, too much work right now. TBH we planned to release it earlier, but not everything is ready right now. There will be more forum activity (here and on BDC forum) before the release.

The moment you release it I will start solo mining and make a brief, non-animated straight to the point youtube video and pst the link on reddit plus the forums to try and get at least 100 initial users to spread the word from there :).  and of course ill put links in the description!!

Abitcoinfuture, thanks a lot!

I'm really glad that I made it ninja, withought fixed date and time. There were a lot of work. Right now the official pool is almost ready, it will support custom rewards system.

Stay tuned  ;)

Any updates?
I like the look of this coin, the branding is quite nice, as are the policies on exchanges.
I don't like premine existing, and would donate, if you instead provided a donation address, and solo-mined with the rest of us. ^-^
I'll mine this from day one, if I'm able to, although I honestly hope it's not released until the weekend, or later; as I'll be off the grid for all of the week until Thursday, missing the launch would be kind of horrible.

I like the logo,lol

any news ?

ShadowOfScales, jioy, djm34 thanks for your interest!

We've got the official pool now up and running and tested :)
We've tested the solo mining in the wallet and pool mining with different load, difficulty adjustments are correct. We switched to DGW difficulty a adjustment, it's way better than KGW.

We plan to make alt logo with asian dragon (like this http://khongthe.com/wallpapers/abstract/chinese-dragon-226978.jpg) to stay in touch with fantasy lovers from Asia :)

Stay tuned  ;)

Sounds interesting

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

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.

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 :)

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

+ 1  ;)

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 :)

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.

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…

PM me for a bounty  ;D

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  :D

That's nice!  :D

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. 

http://listdose.com/wp-content/uploads/2013/08/The-greedy-never-know-when-they-have-had-enough-256x300.jpg

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  ::)

Starting Long Term Development :D

+1 for DEV for sure, I have never seen such a carefully planned launch before. Keep it up.

Cheers

Can the logo Dragon breathe fire and every once in awhile snort in the wallet?  If you could do that, you would be awesome.  

Synopsis:  A polyhedral dice roll simulator that works like this:

Sorry that my mindmap is not as fancy as the devs ;D

Feature: Polyhedral Dice Roll Simulator and Betting System

For coins to grow they need to have utility.  So what about a built in polyhedral dice simulator with betting/tiipping system for us old school RPG dudes?  GM controls an off the blockchain wallet, the players use that wallet till gaming ends, once it ends either offline game wallet held by GM calls for transactions between the party members and GM verifies them before publishing to block chain or a fully decentralized approach with an escrowed wallet that neither GM or players have direct control over.         

There are numerous open source dice simulators and GM tools.  We would not be coding it from scratch.

https://www.ohloh.net/p/polyhedral  -- poly dice simulation

http://sourceforge.net/directory/games/rpg/os:windows/freshness:recently-updated/  -- numerous GM tools that could be added

Does the community think it is worth implementing such first of kind features in an altcoin?

Please post responses in this thread, no PMs for now.  Thanks.   

That could be fun if it does not add too much complexity to the coin making it cumbersome.
Do you think it can be implemented in such a way?

Please do not post pre-reg pool advertisments. First you will have to check our code, handle the bonus rewards, test them and if you will have a working pool, I will gladly advertise it in the first post when the project will be launched. It is not easy to support additional bonus transaction, you'll have to change pool code.

Feel free to PM me about setting up a pool :)

interesting

I don't think -algo=scrypt_jane:9 will work.
the format is -algo=scrypt_jane:StartTime,nmin,nmax

I am quite interested in this launch. specific launch time posted yet?

EDIT: nvm ninja launch it is :)

djm34, We use nfactor 9 for the start and it wont change for several months. If you choose the single nfactor, there's no need to set starttime.

yes you are right it works

@djm34: Please don't instamine this Coin to death again like MNR before :)

with DGW, it might end up with no block at all...

launch in 15 minutes!!!!
