1  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN][LK7] Lucky7Coin - PoW/PoS, BonusBlock based on your lucky 7s! |No Premine on: September 16, 2013, 05:26:16 AM

Lucky7Coin (LK7)

It is a PoW/PoS coin with a completely new algorithm to compute superblocks. Lucky7Coin is in the family of PPCoin/Novacoin with latest available algorithms that fixed various problems in the recent PoW/PoS coins. As compared to the PoW only coins, the proof of stake coins are more resilient to 51% attack. Also it is a long term energy-efficient cryptocurrency.

Lucky7Coin provides superblocks based on the number of lucky "7"s in the previous block hash. The block payout is determined as follows:
- the hash contains six 7s or less: 77 coins per block
- the hash contains seven or eight 7s: 777 coins per block
- the hash contains nine or more 7s: 7777 coins per block

The 777-coins block occurs approximately 3-8% and 7777-coins block occurs approximately 0.5-2%, depends on the blockchain "luck". So have fun and hope for best of the luck of 7s!

Lucky7Coin also provides 5% annual interest on the coins held. The interest is paid about every 2 weeks.

No Premine.
