They do a terrible job with the documentation... making TB4 (superior) sound like it is USB-C (3.2 or something?). Only the Intel versions seem to support Thunderbolt, the AMD not which I think is the main issue.
Anyway, the next Frameworks need to adopt Thunderbolt 5 to handle modern HDMI 2.1 and 2.2, eGPU, Oculink, etc.
Why not use the Bitcoin Lightning Network? It allows faster transactions then MobileCoin and much better privacy than on-chain Bitcoin. Privacy doesn't match Monero, but will undoubtedly improve over time.
Clearly this would prevent the "get rich from pre-mine" benefit, but also remove 99% of the criticisms related to greed, centralization, geographic limitations, etc.
I don't see how MobileCoin can be censorship-resistant, neutral or permissionless in the long run. Are those goals of the project?
