This is a great post. I can understand all of this.
But I need few more information.

Let's say I have 1% of tokens.

1. Am I eligible as a producer ?
2. What is the difference between me and someone has 2% tokens?
3. What's the incentive for me to participate in producing?
4. How do we store the data. I mean how do we handle the growing amount of blockchain data. Is there any kind of sharding?
