EOS on The Possibilty of The "Freemium" Model
The "Freemium" term was coined since it allows developers to build on EOS without requiring any fees.
The Delegated Proof of Stake enables any person who joined EOS Blockchain to participate and holds EOS token to vote for a validator. It works similarly to the Proof of Stake (POS) but it has become more user-friendly that it allows developers to build EOS without fees involved so as to keep it running.
EOS has its unique characteristics and indeed revolutionary to crypto space.
