Someone with more knowledge of these thing, let me know: Why does Tor not "charge" per request? i.e. Using some decentralized currency, to pay for requests. 1. Make it cheep enough such that users don't care, however, financially disincentives spammers/malicious users. 2. It would continue to be anonymous. - cycle through wallets - all transactions would also be proxied. 3. It would incentivize proxying and exit nodes (exit nodes would effectively collect a bunch of virtual money to be resold to clients for USD).
