I have a few technical questions, and hope someone can answer them.
I have done already my research, but some points are still unclear to me:
1.) Are projects like TenX (ERC20 token) running on the Ethereum Blockchain or on its own?
2.) Can any ERC20 token choose its own consensus model? PoW, PoS, etc.
3.) Why would one make a private blockchain? What are the reasons for this?
4.) Is it possible to replace one token with another? e.g. the blockchain technology must be radically changed?
5.) Is it advisable to store more than pure transaction data in the blockchain? For example, the number of victories of every national soccer team worldwide?
Thank you!
