We are being treated to some new cryptocurrencies which have decided to take the PoW route for the first few thousand blocks, followed by a full switch to PoS.
Even though this does seem like a good way to go forward, only so many coins adapting the same strategy will be successful. BlackCoin might be one of those coins.
BlackCoin is a Scrypt coin, with blocks generating 10,000 BlackCoin, and blocks being generated every minute. This is one of the very few coins which does not have decreasing block rewards.
Then again, as soon as the block height has reached 10,000 , there will be no further rewards from regular mining, and only PoS blocks will be generated.
Annual stake for BlackCoin is 1%, which might not win too many people over, but the minimum coin age to generate PoS blocks is only 8 hours, which is a lot lower compared to other cryptocurrencies.
