the concept of taint is all or none. either coins are spendable or they're not. for a UTXO that has 25% taint, is it spendable or not, bro?
WTF are you talking about? If you want to send me a transaction consisting of 100% validated UTXO's, I'll except them at 100% face value. If you want to throw in a fraction which are unvalidated I'll discount them accordingly. If/when unvalidated UTXO's cannot be mined or take a long time I'll stop accepting them altogether or accept an accourdingly deeper discount.
This is utterly trivial. Coinbase will do it automatically which is why I'll just accept payment from you through them.
you still haven't answered my question about how the US gvt could get away with the hypocrisy of auctioning off the SR coins while at the same time tainting others drug coins. that is more of a political question and i already know your answer.
Not hypocritical at all. You bought some coins at the auction? Register and validate them. No big deal.
I anticipate that as things are rolled out probably every single UTXO will be considered clean by default. Nobody is stopping you from validating any of them so you've got no complaints...unless you are a criminal or whatever and don't want to register...
that's assuming you or anyone else has the ability to determine whether or not a UTXO has 100% cleanliness. i'd say it depends on who is doing the analysis. you yourself admitted, after i pointed it out, that you might indeed have stolen coins from allinvain in your wallet. should we lock down your coins?
if it's so trivial, tell us how splitting out UTXO's works technically. wallet software follows a particular logic of UTXO selection when assembling for a specific tx which i've not been able to get a good sense of and i'm sure you haven't either. there's no such thing as "UTXO control" like there is "coin control" for addresses, afaik. tell us how you would construct a tx to select or exclude certain UTXO's that you'd deem tainted. from what i do know, the wallets select the most suitably "sized" UTXO's which when combined together fits the tx amount so as to minimize splitting and efficiently packages the tx at the least cost in terms of fees and data requirements. furthermore, for a UTXO that has 0.15% "taint", tell us how you'd split that out practically. stop pretending that Coinbase has a way to do this when you don't know that.
what you're proposing is "possible" is mostly likely not possible and certainly is not "practical". i've never seen any wallet with the ability to allow users to spend certain UTXO's. what would be the point except to satisfy your socialistic mandates?
