vDinar is a cryptocurrency using vCrypt as a proof-of-work algorithm, aimed to help money transactions between southern slavic countries. Of course, it is available to everyone else besides being from Balkans or not.
What's new in vDinar?
- vCrypt protocol/algorithm is similar to Scrypt-N, but changes the N factor at blockchain heights instead of hardcoded timestamps
- allocates 2% of every mining reward (fees included) to a special address for donations in the Yugoslav area
2.5 minute block target, subsidy halves in 840k blocks (~4 years)
- 49+1 coins per block (49 to miner, 1 to donations)
- 2016 blocks to retarget difficulty
Block structure differences (from Bitcoin)
- 2 coinbase (no input) transactions instead of one
- both coinbase transactions include the same extranonce
Pooled mining differences (server side): (On work request)
- create two coinbase transactions instead of one
- assign the 49 coins to first coinbase
- assign 1/49 of the first coinbase transaction value to the second one
- store merkle steps from the 2nd lvl., considering two unknown values (coinb. txs) in the 1st one
- send splitted coinbase transactions (coinb1, coinb2, doncoinb1, doncoinb2), merkle steps and all the rest (On share received)
- hash coinb. and don. coinb. txs
- build hash merkle root with the latter result hashed with merkle steps one by one
Pooled mining differences (client side):
- receive 2 new values (doncoinb1, doncoinb2)
- build hash merkle root with first two txs as coinb. and don. coinb. (both with same extranonce)

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.
If it is a simple/trivial/non-controversial change, then one of the Litecoin development team members simply pulls it.
If it is a more complicated or potentially controversial change, then the patch submitter will be asked to start a discussion with the devs and community.
The patch will be accepted if there is broad consensus that it is a good thing.
Developers should expect to rework and resubmit patches if the code doesn't
match the project's coding conventions (see doc/coding.txt) or are
controversial.
The master branch is regularly built and tested, but is not guaranteed to be
completely stable. Tags are created
regularly to indicate new official, stable release versions of Litecoin.
Testing and code review is the bottleneck for development. Please be patient and help out, and remember this is a security-critical project where any mistake might cost people lots of money.
Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code.
Unit tests for the core code are in src/test/. To compile and run them:
cd src; make -f makefile.unix test
Unit tests for the GUI code are in src/qt/test/. To compile and run them:
qmake BITCOIN_QT_TEST=1 -o Makefile.test bitcoin-qt.pro
make -f Makefile.test
./vdinar-qt_test
Just use vDinar, that's the best donation!
