Where you did find this information? On etherscan?
And about the 1000EAST is 1 share, it is not considered that it is something like a masternode? For example you can own 1 DASH, but you need 1000 DASHs for setuping the masternode?

Thank you for your question.
You are right. The idea behind the ASN shares is indeed a "masternode" style passive income, without the additional resources for network protection, since Ethereum is already safe and secure.
