Contentos (COS) Decentralized Content - ICO Review, Rating and Details of Contentos ICO (Token Sale) - Rating: Not Rated

Contentos is a blockchain protocol that aims to form the foundation for a decentralized digital content ecosystem that empowers all members, including creators, consumers, and advertisers, to earn fair compensation for their contributions. Contentos also intends to establish itself as the future Ethereum of digital content, accepting content DApps of all kinds.

Problems & Solutions


  • Unverifiable digital assets: In the current digital content ecosystem, it is difficult to validate the copyright of digital assets, as it is not easy to trace the flow of copyright information across multiple independent platforms. Unfortunately, these challenges lead to frequent copyright disputes, especially for derivative works.
  • Non-transparent industry pricing and uneven revenue distribution: On centralized platforms, creators are pushed to the industry sideline and cannot reach consumers and advertisers directly. What’s more, the content and advertising pricing is not publicly disclosed, resulting in a lack of transparency that disempowers creators. Payment channels and platforms take a huge portion of users’ income, while advertising revenue is centrally-controlled by platforms, with only a small portion of it going back to content creators.
  • Users' true interest cannot be satisfied with current platform algorithm: Centralized platforms distribute traffic based on revenue drivers, a system which fails to offer a full picture of the value of content created by influencers. Because centralized platforms depend on ad revenue for survival, the creators that contribute most to advertising ROI are rewarded handsomely while emerging creators are ignored. Such a system leads to homogenization and lower quality content.
  • Flawed credit system: User engagement data in centralized ecosystems are not transparent. Users are not held accountable for fake comments causing the credibility of the rating system to gradually decline. Violations and poor behaviors are often not tracked across platforms, and errant users are rarely penalized for their actions.

Contentos’ solutions

  • Verification, trade, and storage of non-physical property rights through the Contentos protocol will enable quick and comprehensive access to copyright information. Trade flows and derivative works will be recorded permanently on the blockchain. Content creators will register their copyright and provide original content statements, authenticated, and traced with time stamps.

  • Decentralized distribution of revenue: In the Contentos ecosystem, pricing is transparent with the value of any contribution determined by artificial intelligence-based algorithms and recorded on the blockchain as public record.

  • Decentralized traffic distribution: The Contentos protocol decentralizes the distribution of traffic, thereby forming the foundation for a more democratic content ecosystem that supports emerging creators in finding and building an audience.

  • Immutable credit system: In the Contentos system, the interaction log cannot be tampered with, and so each user is held responsible for his or her own behavior. User credit will be based upon the quality of content, trustworthiness of user selections, and other relevant records. All revenue calculation algorithms in the ecosystem will incorporate this credit score. Users can improve their credit scores through demonstrating positive and honest behaviors, thereby earning more revenue and increasing their credibility. In this way, users collectively build a reliable, self-sustaining review system.

Features & Highlights

  • Intelligent content advertising: Smart contracts are used to facilitate advertiser payments to creators. Rewards are automatically distributed to the creator based on viewership and interaction data. A creator and advertiser can make agreements for additional compensation, or bonus incentives, if work exceeds expected results.

  • Direct value exchange: Users can pay creators directly through subscriptions, donations or virtual gifts, all executed automatically utilizing smart contracts. For example, creators can create exclusive content that can only be viewed a fixed number of times for subscribers. Through this type of empowerment, creators can more easily grow their viewer base, develop loyal followings, and increase their revenue.

  • Content selling: Contentos enables the sale of content within the platform between creators. For instance, a video creator may publish a soundtrack request and allow music creators to bid for involvement, just as a music producer may publish a 15-second soundtrack for purchase and use by a video creator. Profit sharing may also be achieved through smart contracts. Since all transactions are transparent, every creator understands his/her unique value within the ecosystem.

Token Utility & Use Cases

  • Rewards for content creators for uploading original content. 

  • Income for content distributors for recommending and matching the content to the target audience. If the users show that they like or dislike the content, or actively promote the content, they can be rewarded with tokens and credit score rewards in line with their contribution.

  • In addition to general interactive behaviors such as Liking, sharing, and commenting, users can also use COS to purchase virtual gifts for content creators to express enjoyment of content. For content creators, received virtual gifts can be converted back to COS after deducting the developer's share.

  • Users can use COS to purchase ownership of content, allowing creators to obtain larger, one-off payments.

  • Any developer who participates in and contributes to the Contentos public chain development can earn COS rewards regularly in the development phase in accordance with their contribution.
