Currently resolution is hardcoded, but sure, can be done. Also need to figure out things like changing language/keyboard layout or using IME, to be able to type text properly. Sending mouse cursor picture from server to client may be nice too, in case a game uses hardware cursor and changes it's appearance, like some RTS games - currently mouse cursor is just being baked into video frames. Many possible improvements!
Sure! it uses the NEAR blockchain to get a chain signature based on the email address extracted from the token. The email is extracted from the unsigned token message that is sent to the smart contract along with a zero knowledge proof of the signature. The smart contract verifies the proof and then signs the user's payload using the email address and aud in the derivation path in the call to NEAR chain signatures.
At this stage yes but I'll be adding the ability to add a public key to your account on the smart contract and also deauthorize the proofs if you want complete custody. We can make the journey to full custody more gradual to improve UX.
You don't generally need to license Arm chips unless you are designing your own chips for sale, like STM32 or Raspberry Pi do. This is something very few companies do, relative to those who just build things from existing chips.
If you're just building something with an existing Arm microcontrollers. The vendor (Like STMicro) has already licensed the Arm design and sold it to you.
