Hi Sammy,
you are right.. the time between blocks is strange..
i dont know yet if i made a mistake in difficulty calculation or if its right and it is just because sometimes i stop the seed node to solve some bugs..
Seems the chain stuck at block 1205?
Also why the time between every block is like more than 30 mins.
Now I see most of the bugs are resolved. I am trying this from day 1, now I have mined around 350 coins and those are still on blockchain and not disappeared.
Earlier whatever I mined all coins were erased.
Thanks

Yeah, i will do this.
This coin is just a Bitcoin implementation, but simpler.
This has some big advanteges. Without script language, the blocks are much smaller.
In short:
- It is much more decentralized in terms of having more developers able to develop the currency
- It allows miner to create transactions for other people, join their money. Example: John has two outputs (5 and 6 bitcoins). The miner can create a tx to john join the 5 and 6 in one output of 11 bitcoins, decreasing UTXO space.
- "Human address". Your account/address is like 12345-6.
- The address is an Integer, a pointer to the publick key (about 4 billions of possible address). So, the tx is much smaller and can be a lot more of them in a 1 MB block, for instance.
- Im putting just one tx per address, per block. This limitation protected the nodes from flood and allow transactions without fees.Its a simpler Bitcoin. Its a better Bitcoin. 
I very much liked the java codebase.
Great job by you. Can you also post more details of this coin on the opening post, so people will read everything on the first page.
What are your plans on this coin?
