i did not mean writing a block i meant writing / creating transactions / if someone tries to spam the network.
how writing a block is functioing in ucoin i know. how spam protection is handled currently in ucoin i dont know yet 
that is what i do not understand. its my choice if something has value for me or not and if so how much.
so why to restrict my freedom how i can interact with someone if i want to exchange limited space for someucoins?
but I will read the RTM, maybe i have already read it, but i will read it again and again
