Hi!
Today i was thinking about an old affirmation of the dev about the fixed transaction cost amn how they will implement a "dynamic" fee based on the "weight" in kB of the transaction.
I had an idea, that probably will never work or is totally incorrect, but maybe someone smarter then me will have some usefull inspiration:
Monero is an anoncoin with possible multiple encription layer, you can choose, while sending the transaction, how much you want it to be encripted and, obviusly, more is encripted, more it weight and more it will cost.
I was wondering about an option who let people do not encrypt their transaction and then send it without transaction fee (or with really low fees). Plus, we can use both the current algo plus Proof of Stake; all the client will become node and they'll prioritize these "free" transaction while miners will prioritize encrypted transaction (that with their fees will help ghe network keep running). Client of the PoS, if i recall correctly, will act as a torrent client, sendind and receiving transaction with little power and bandwith consumption, but they'll not receive any payment (or a really small one, like an equal [not proportional] distribution of the low fees).
I think this could be a really good feature!
Please do not kill me for this tought and sorry for my bad English!
Your English is fine:) Let's take Proof of Stake out the picture, as PoS is flawed in many respects, and that is a discussion for another time. The rest of what you're saying is spot on, and it is both how Monero works and will work in the future. The higher your mixin level, the more signatures you mix with for your transaction. But then your transaction is also physically bigger (in terms of the kb size of your transaction). When we move to per-kb fees, this will mean that the higher your mixin, the higher the privacy (more ring signatures), and the more costly that transaction will be to you.
