JKC Coin, the newest altcoin which is Litecoin-based has arrived!

Codebase at https://github.com/js2082/JKC

I compiled Windows 32bit binary (tested with Windows 7 and 8 ), click on file->download:
https://docs.google.com/file/d/0B4p3l1ebwJ39RVFxNTh0X1JmZEU/edit?usp=sharing

For all other systems, you need to compile from source code.

http://en.wikipedia.org/wiki/Junk_%28ship%29

The new feature of this coin is that it added random coin size per block (see below), so even late in the game, you may still hit a block of 1000 coins! Like real gold mining, you may hit different block grade:-)

Below are features:
  
   - Total coins will be around 107 millions
   - 1 minutes block target
   - Difficulty retargets once per day
   - To encorage early adoption the coins per block is high for the first 4 days:
      - 1st day: 500 coins per block
      - 2nd day: 200 coins per block
      - 3rd/4th days: 100 coins per block
   - Starting 5th day, it will be 50 coins per block. It will also be halved about every two years (every 1036800 blocks).
   - Mining will be shut down after 12 years.
   - In regular mining (after first 4 bonus days), there will be 1% chance a block will yield triple of the
      normal coins (e.g. in the first 2 years there's 1% chance you get 150 coins per block).
   - There is also 1/10,000 (0.01%) chance that a block will yield 1000 coins. This is valid for all 12 years
      of the mining.
   - The default ports are 9771 (connect) and 9772 (json rpc).

The first 100 blocks are special blocks of 10000 coins each. They are premined for bounty purpose. The 1 million coins premined will be reserved as bounties for pools, exchanges, wikis, support groups, giveaways, faucets, etc, etc. If there are sufficient interests, we can form a committee to manage the fund, in which case I will hand over the 1 million reserved bounty (minus those spent - see below) to the committee.

For now, I offer the following bounties:

JKC mining pool:
   1st pool: 8000 JKC (p2pool by WOPR: bounty 8000JKC sent)
   2nd pool: 5000 JKC (LeftToeCut: bounty 2000JKC paid, rest 3000JKC after 3 days)
        3rd pool: 5000 JKC (niteryder: bounty 2000JKC paid, rest 3000JKC after 3 days)

Exchanges:
       1st exchange: 150,000 JKC
       2nd exchange: 100,000 JKC

Other bounties will also be offered as needed for activities that significantly promote or enhance the awareness of the JKCs.

Are the "random" numbers used to make the rewards "random" deterministic, so that all nodes will all agree on the correct "random" reward for each block?

Because if they do not agree what reward the block should have, they will reject it, the net will split and split and split constantly as each node comes up with a different concept of what the correct block reward for a particular block should be...

At a quick glance I don't see the necessary determinism... where is it? If it is there at all?

Yes it is. Using boost Mersenne Twist which is deterministic. So theoretically it is not completely random, it is pseudo random

Well because of low difficulty, some fast computer gets them...
