Currently, the fees work like: every time you make a write to the blurt blockchain, it will charge you a 0.05 blurt fee. Additionally, blurt will charge you 0.01 blurt per kilobyte.

Personally, I will soon change my witness configuration so that there is only a 0.09 blurt per kilobyte fee. Blurt will select the median of the witnesses choices on fees. Personally, I would like to see a higher per kilobyte fee and no per transaction fee. every transaction results in a write to the chain and has a storage requirement. therefore, to me it makes sense to charge based on that.

Big transactions will cost more, small transactions will cost less. Every transaction will be priced based on how much storage it requires.
