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 to a special address for donations in the Yugoslav area
- (optional) transaction fees split 75% to miners and 25% for donations
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)
