I explain how action of valuable resources leads to better price discovery and maximizes profit for owners. I highlight the advantages of HCS, including its affordability, fair and older timestamp, verifiable delay function, and commit reveal skin. I also mention that HCS serves as both the consensus mechanism and the publish-subscribe mechanism. Finally, I demonstrate a name service example and show how messages are passed on the HCS system.</description></oembed>
