Thanks for the post. I am eager to learn more about EOS, hoping for some tutorials.
I have some thoughts to Data Management:
When Datastorage creates costs, then Data has to be managed in some way. Not needed Data has to be removed. How is this fitting with the immutability "feature" of the blockchain?
I am wondering how unneeded/unnessesary data is defined and who gets to decide which data can be removed. Would make sense to me to give the decision to delete data to the persons that "own" them but in the end the App Developer has to decide about the storage if he is the one staking EOS to pay for Bandwidth/Storage for his app. Can permissions to data operations be handled individually in the EOS Storage?
