In creating a platform for others to create and use tokens, I want to stop spamming or adding too much data to transactions. A little like Waves or NXT I guess. I could do that with native currency which would be sold to nodes who want to transact with their tokens, but once issued I am stuck. I think it better to wait for transaction filters to be implemented where rules for transacting tokens can be set according to each token, or across all tokens on the chain. Am I right? or am I missing something that we won't be able to do?
