I have designed an economic model that calculates the block size dynamically in order to mitigate the attacks against the network. I intend to submit the proposal to the vote of the masternodes. If the proposal is approved, it does not mean that it will be implemented. It means that the DAO considers the proposal as a possible way to go. The vote allows we to know the opinion of the investors without the noise caused by the debate. The cost of the proposal is just the reimbursement of the fee if the proposal is approved. The link to the paper follows in another post.
