Just began researching Crown.  Longtime masternode operator, but my level of involvement in other projects has kept me head-down for a long time.  So, I have a few questions.

• What sets Crown's NFT platform apart from any other platforms offering ERC-721 alternatives?
• To what degree is the NFT platform scalable?  If it is highly scalable, how?  I like it when projects pursue scalability in a proactive manner.
• Does Crown produce superblocks?  If so, how often, and how much is generated?
• Are governance proposals & voting records retained historically?  If so, where can I view this?  Would especially review proposals where Core design decisions were made via governance & carried-out.
• MM-PoS...  does this imply masternodes are block producers?  Anything you'd like to tell me about this structure?
• Was any other means of consensus used prior to MN-PoS?  If so, what was it, and why did it end (honestly)?  Not particularly a fan of PoS nor its variations, but I have an open mind.

I might have more questions, but this is all for now!  Many thanks in advance.
