We are discussing some technical storage problems in these thread:http://forum.bitcoin.org/index.php?topic=9295.0
The proposed solution would solve problems like:
-Lack of direct compensation to miners for storage (with the current model they would be compensated through transaction fees).
-Everlasting free storage for other applications by "burning" bitcoins.
-Storage of "lost wallets". Also potential economic problems (if any) also derived from wallet losses.
Also another question has arose:
Can miners prune "old accounts" that are not empty?
What prevents/discourage them to do that?
Creighto even doubts the feasibility of his own proposal. It would be interesting to have some developers there.
Please don't confuse creighto's proposal for flat demurrage fees after a certain time in the block chain with mine for a demurrage rate for holding money. They seek different ends.
No one seems to like my proposal, so I think we should discuss creighto's proposal and leave mine (freicoin) to other threads.
If you're concern with the some evil financial effects from proportional (to the quantity hold) demurrage, we can discuss it there too.
Creighto's proposal doesn't have financial effects because bitcoin owners can avoid these fees by moving their bitcoins from time to time.
