Just start using HTTP 402 and JSON payloads. We can just converge on whatever ends up common; for me, there is already a monetary standard for the Internet.
I participated in these meetings for some time, during the rise (and rise) of Bitcoin. It's clear that the landscape of the financial web has shifted significantly at this point (for better or worse, in many ways), but standards, as usual, lag the market.
This explanation shows a painfully shallow understanding of Bitcoin, if not an intentional bias. Bitcoin is capable of doing everything Brave would need, and they've been shown how to accomplish their goals multiple times by numerous disparate parties. I'm increasingly convinced Brave's leadership is opposed to the idea of self-determination, and is playing politics by making up these kinds of excuses.
They're just using privacy as a marketing tool, as user behavior can be tracked externally by observing the transactions on the network. Brave makes things objectively worse.
Brave is a scam, with user funds being seized and converted into other currencies against their will. By issuing their own token instead of just using Bitcoin, they re-implement the same central banking system which the technology is designed to replace.
