These 2 coins are interesting. They do add something unique (proof of stake, prime chain hashing), but I am concerned about the centralization of their checkpointing system. One thing about Litecoin (and Bitcoin) is that no one can shut it down. I can’t shut it down. This is not the case with a coin that uses centralized checkpointing. In order to shut the coin down, you just have to force Sunny King to add a bad checkpoint. This was also the case with Solidcoin."
Any community response?
