# ADChain Blockchain After gaining enough trust and recognition from the public, ADChain Blockchain will start functioning independently. The proposed ecosystem contains four components: a public and decentralised blockchain, a campaign management system to maintain the end-to-end lifecycle of a campaign, an ADPlace that aggregates all the published advertisements, and a DApp, which is an interface between end viewers and the world of ADs. The Blockchain is tightly coupled with a native token, ADCoin, which is used to publish ADs and reward viewers. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
