"The people in this room hope for a world where an individual's informational footprints—everything from an opinion on abortion to the medical record of an actual abortion—can be traced only if the individual involved chooses to reveal them; a world where coherent messages shoot around the globe by network and microwave, but intruders and feds trying to pluck them out of the vapor find only gibberish."

"If you go into a store today and make a purchase with cash, no records are left tying you personally to the transaction. With no records, there is nothing to go into a computer database. The goal of electronic cash is to allow these same kinds of private transactions to take place electronically."

"It is important to realize that while distributed consensus is a hard problem, ordinary consensus is much easier and better studied, and can be solved some trillions of times more efficiently by use of trusted identifiable signing parties. Therefore, cryptocurrencies which compromise by introducing trusted parties, even under limited circumstances, should consider whether their new trust model is one for which consensus is easily achieved by some other mechanism."
