With bitcoind 0.9 the rules for tx fees are no more hard-coded. This is good. But it is hard for the nastyfans policy. It maybe not clear what tx fees to add to purchase order prices.
I ask for feedback on some ideas:
Maybe there is no tx fee added to purchase order prices. And payments to sellers are added to weekly distribution instead of separate transactions. This reduces purchase order costs but adds tx fee costs to the distributions.
Another idea is to set a fixed purchase order tx fee cost that goes into a new tx fee account. Payments to sellers are added to weekly distributions and the tx fee account is used to help pay distribution tx fee. This does not reduce purchase order costs but will reduce distribution costs.
Would it be difficult to allow each fan to choose his/her own tx fees?
Offer a 'recommended' default amount based on best practices, but allow people to increase the fee they pay for their transactions if they want faster confirmations, or a lower/free fee for fans whose confirmation time is not a priority. (ie transfers to cold wallets)
This way you can eliminate any 'system' fees and no one can complain about the fee because it's entirely the users choice.
It's an idea anyway....
Both of nonna's ideas leverage the multiple out feature of transaction by bundling sales and distributions so the speed at which transactions are processed are not really the issue per se ... more how is the fee that nasty mining will pay be collected.
My 2 bitcents... Charge a low fee to seat sellers only at the time their seat is sold, up to an agreed upon max which will cover a reasonable fee, any excess is returned to nasty mining as part of the distribution, any short coming is paid out of the nasty mining distribution. A reasonable calculation for this would be to take the average number of seats sold per week (eliminating out lying weeks where there was little trading and weeks where trading was considerably higher than the norm) and then divide the agreed upon fee among that many trades then add a small % on top to help hedge toward the transaction fee being covered by seat sales. Morale of the story is that a single seat sale should not incur a full transaction fee and hopefully be considerably less.
