The following is a dump of full HTML files (identifying parts removed) of private Bitcoin Foundation discussions on Bitcoin blacklisting, transaction reversing, and create a new proof of work called "proof of sacrifice" for asset forfeiture.
Proof-of-sacrifice has nothing to do with asset forfeiture. It's an idea I came up with
last year, which was subsequently developed further by
myself and
Mike Hearn among others for various applications. It's just a way of making a (potentially) anonymous crypto-identity expensive to obtain, which is useful for things like controlling spam on (pseudo-)anonymous discussion forums or making it possible to have anonymous financial services. For instance BitMessage could have used it in favor of direct proof-of-work.
OP: Please correct your post.
