request of information

self.Monero1m ago
Greetings, I would appreciate if someone could share some information about fundamentals of monero. 1. Is there an organization behind monero like in the case of cardano or algorand? 2. Can the protocol be changed by a small group of people or it will require a massive consensus like in the case of bitcoin? 3. Is there a maximum supply? 4. Are there any problems related to scalability. Number of transactions per second and those sort of things. Thank you for attention.
