As great as Web Payments is, there are obvious problems with the system (largely around privacy and anonymity). At Brave we launched a similar system on the BAT (ERC20) token. In Brave Rewards (formerly Brave Payments), users are able to (via ANONIZE2 and ad-hoc VPN connections) anonymously contribute to content creators based on attention distribution. If the browser spent 10% of it's time viewing the content from one particular YouTuber, 10% of the user's monthly BAT budget would go to the content creator. This system leverages the pseudononymous nature of the blockchain to offset the cost of user an ad-blocker. Low friction, privacy, and secure.
