no in the case I was sketching in my email you don't actually replace =he dollars, you just replace bitcoins. The only reason why you want to =eplace bitcoin is to get their network power which is needed to solve =he multiparty consensus problem (the double spending attack).

Now in one of the other potential options you don't even need that, if =ou enforce identities you can also guaranteed benign multiparty =onsensus on transactions as long as less than N/4 actors are malicious. =Filch in practice means you don't need to have that many people in your =etwork mining coins.

Also yes you can easily embed transactions descriptions/codes.

There's always the risk of actually losing or having your 'wallet' =tolen, but you cannot avoid that 100%. You can either do what some =itcoin services do (it's called called/hot storage) or have the govt as =n insurer of last resort.

I feel like that story you told me about you trying to decode hand =ignals back in the days, in the sense that I'm either missing something =ere or my pessimistic view of things is shaping my thinking too much - = don't see why anybody but governments would want to have this. In any =ase, forgetting that for a moment and assuming companies want to do =his then you can do it quite easily.

anyhow, it's probably worth to talk about this F2F in Santa Fe if we =anage to work that out

3) A little known fact is that you can mess with the blockchain/ledger =uite a lot, for instance somebody forced specific values into the =edger. For instance, these values could be virus signature, so antivirus would quarantine/delete the blockchain from people =omputers. Not only that, but people have been storing all sort of stuff =nto the blockchain and it's permanent you cannot undo it.
See: http://pastebin.com/ct2WHUK5 and =ttp://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.htm
ok so here's what you do if you want to fix (1) and (2), I don't have = good solution for (3) unless you change the power forces inside the =etwork (eg: unless you allow a centralized unit to 'clean' the =lockchain)
You create another crypto/alt currency that is inflationary so it =imics real money better, then you tell people: "everyone who has =itcoins can get them exchanged for this other currency".

Anyway, this is in short how you go from bitcoin to another currency =with the properties you care for) while preserving the bitcoin network =nd its strengths. As I said, not sure if it's useful/interesting but I =igured I'd share it

Another thing: any chance I can crash at your place in Santa Fe say =ug 8-10? I'm still not sure whether I'm supposed to be there or not, =ut I figured that maybe it's worthwhile to go and visit anyway

ps: note that the moment you remove anonymity from bitcoin there's a =ignificant privacy problem. Meaning that now everyone knows what you =uy/sell through bitcoin, it's advertisers (among others) sweetest
