Contentos (COS) is a blockchain project that aims to build a decentralized content ecosystem. The COS token is an ERC-20 standard token and serves as the primary medium of value transfer within the Contentos ecosystem. It is used to incentivize content creation, facilitate transactions, and serve as a governance token. Contentos was co-founded by Mick Tsai and Zac Nien, with Mick Tsai serving as the CEO. The platform aims to provide a decentralized, censorship-resistant space for digital content creators and their audiences. Advertisers must use COS tokens to pay for advertising on the platform. This ensures that the value of the token is tied to the utility it provides within the platform. Users can also earn COS tokens by participating in the platform, such as by viewing content, commenting, sharing, and liking.
