Rather thanfight over which sacrifice to make, we should create an environment in which theseobjectives are compatible. The first innovation of the system is to digitally sign all transaction records, and to integrate this signature into the payment system itself to create tamper-proof records.

If a system cannot provide (at least) the same degree of auditability, it may not meet the demands of users to be protected from fraud[17], or the legal requirements of tax collectors [16,17]. It would be most efficient for a single agency totake responsibility for some of these tasks - probably a federal agency. For example, this receipt can now serve as a proof of purchase in an electronic commerce transaction. Indeed, as the next section will show, multiple parties should play this role so that no one entity can compromise the privacy of others. One final limitation of this scheme is that a list of all spent coins must be maintained, and frequently searched. An entity that served as both a verifier and a notary (like a typical credit card company) would therefore know that a given customer is processing transactions, violating privacy objectives.
