How it Works

Decentralization of the conventional distribution channel that connects creators and consumers. Contents Protocol enables distribution margin, which used to belong to centralized platforms, to be shared fairly and transparently among the network contributors such as creators and consumers, according to their contribution.

How it Works


In order to speed up the expansion of the Contents Protocol Ecosystem, 
the Corporation will launch an open source reference platform for each content category of TV, Music, Comics, and E-Books, reducing barriers for potential content platform operators to do business in our ecosystem.

In the beginning, the Corporation will either develop a reference platform from ground up or acquire an existing platform and convert it to a reference platform.

For a more vibrant Contents Protocol Ecosystem in the early stage, the Corporation, as an accelerator, may either recruit candidates or invest in and/or acquire existing 3rd party platform operators.

How it Works

* Each platform decides its C&DC indexes at its disposal.

How it Works

Rewarding Users


Automatically staked to the content

  • • 10%* of the payment for a content is immediately converted to CP Power and deposited in the content's staking pool.
  • • Users can boost their compensations by increasing their stakes of CP Power in a content.

User compensation is 
based on the contribution to the network, measured by:

  • • Quantity of CP Power staked in the content and the platform (log scale*)
  • • Contribution score for promoting content or platform outside the platform
  • • Contribution score for content reviewing activities
  • • Contribution score for providing purchasing & rating data to the recommendation engine.
* Each platform decides its C&DC indexes at its disposal.
How it Works

Fair and Reasonable Deal Offered to Content Providers

Complying with the established rules in the industry, Contents Protocol Platforms can offer a better deal than traditional platforms.

For content providers, license fee ratio of Contents Protocol Platform is more favorable than that of the traditional centralized platforms. On Contents Protocol, platform’s operating cost is sourced from the inflation pool, while the distribution margin that used to belong to the platforms is fairly and transparently distributed to content providers and users.

Content providers have an alternative to the traditional license fee payment system. Content providers may choose to be paid real time in CPT Tokens through a fair and transparent smart contract, which encourages a rapid expansion of the Contents Protocol ecosystem.

In addition, content providers can receive bonus license fee by making a stake on the Platform.

How it Works


Why they care
Content Provider

Content providers have two options. With the conventional practice, they can get license fee in fiat via a smart contract, which ensures transparency. When content provider choose to get paid with CPT Token, they can receive license fee on a real time basis, while also getting bonus license fee by staking to platform. Either way, Content providers are benefited from much more favorable license fee ratio.

Why they care

What matters to content provider is to reduce unreasonably high commission charged by platforms and to increase license fee ratio allocated to them. Recurring license fee payment also matters in that content providers are obliged to make a payment to their sub-licensors.

General User

When users pay for a content, a certain percentage of payment is automatically staked in the content staking pool, which accordingly generates rewards (the earlier, the more). They can get rewarded for just using Contents Protocol Platform, which is operated in the same way as centralized platforms, even with fiat, without having any prior knowledge about cryptocurrency.

Why they care

What general users want is easy-to-use, stable service and rewards that can be easily given and used without having any prior knowledge about cryptocurrency.

Heavy User Expert User

Heavy/expert users can have multiple reward streams on the Contents Protocol ecosystem. More CRP will be staked into the content staking pool when the users pay for a content with CPT token instead of fiat and when users want to make an additional staking on promising contents. In addition, users can get additionally rewarded for becoming platform evangelist, reviewing content, curating content and promoting content outside the platform, etc.

Why they care

As the token economy penetrates into every corner of the real economy, heavy/expert users would want to get rewarded fairly for their efforts to create values in the ecosystem and thus choose a protocol providing such rewards.

Platform Operator

Platforms can be operated with little development resources, harnessing open sources such as high-quality platforms and CMS interface. Platform operators receive revenues from the inflation pool. Furthermore, platform operators can start to do their business without having any prior relationship with content providers as the foundation plays a role in connecting with each other.

Why they care

Many existing content platforms are not performing well in terms of product quality, failing to live up to the market’s expectations*, as operating a paid content platform requires a high level of development capability.

At each stage of the roadmap, the Corporation will first launch an open source reference platform. Then, the Corporation will source 3rd party platform operators.
