The Coreum project was created at a pivotal time - many old projects were already in existence and provided lessons to be learned from. A key distinction between Coreum and Ethereum is that Coreum has a fee stabilizing mechanism, which guarantees low gas fees at all times. Ethereum has limited use during periods of high demand because of high gas fees.

When the article was written coreum was deflationary, during the innovation of coreum the developers came to the conclusion that an inflationary model is necessary for the sake of network security.
