BlackCoin started of as a Proof of Work coin but has evolved to a unique version of Proof of Stake. Wallet users can unlock wallet for staking only.

BlackCoin features the following specifications:

- Extremely secure: Among first with fix on SSL heartbeat, Transaction malleability, BIP66

- The probability to sign a block and the block reward does not depend on coinage (anymore).

- Recommended confirmations: 10, maturity: 500

- Minimum transaction fee: 0.0001 BLK

- Defined block time target: 64 seconds

- Max reorganization depth: 500 blocks

- Inflation: about 0.95%.

- PoS block reward: 1.5 BLK + fees

- The accumulated reward is proportional to the total balance and the time of staking. 24/7 staking at current network weight leads to an expected reward ratio (interest rate) of about 5%.

- BlackCoin rewards users who supports the blockchain through continuous staking.
