No in my idea bitcoins aquire a dimension of Age. Every time the Earliest mined bitcoins (the block that gets invalidated) are no longer a valid output so all transactions rooted to them get also invalidated when that block phases out.
as I said above the "moving" transaction will be invalid because it's inputs will be invalidated if they are rooted to a block that got off the rolling window.
That window is neccecary be small it can be say 49 years, so hopefully the bitcoins that will be invalidated are sufficiently diffused so no single person will feel the hit, Unless he is hoarding of course. Essentially this gives greater value to freshed mined coins (they will last longer) and gives equall opportunities even to late adopters.
Thanks! You just reminded me why I hate the economics forum and every stupid thread about "fixing" Bitcoin. You do not have the slightest clue as to how the Bitcoin protocol works or how Bitcoin transactions work or how your idea will never work.
One more thing before I go back to the technical discussions where I belong: all this talk about "changing Bitcoin" is a total joke. Any substantial change to Bitcoin is a new coin by design. You cannot change Bitcoin in any substantial way. You are discussing alt coins: InflatoCoin, TaxCoin, TheftCoin, MagicVanishCoin, or whatever. You are not discussing Bitcoin. The only changes that will ever be made to Bitcoin are small technical improvement that can be done within the established protocol.
EDIT: Darn, I screwed up my edit and lost some text. Something like "Good bye and good luck, etc."
IMO Anything can be changed
But before you go just please tell me if my proposal is technically feasible within bitcoins codebase, if not why? and I promise not to plague you in the techical forums
