ContentBox is a blockchain public chain based on the digital content industry, dedicated to enabling users, content creators, partners, developers and advertisers to share an ecosystem based on the token economy. ContentBox makes it easier for partners to access the decentralized content ecosystem by building a shared user pool, a shared content pool, and a unified payment system. With a number of content platforms that have accumulated more than 20 million global users, ContentBox will accelerate the construction of its BOX payment, BOX identity authentication and BOX one-stop service functions. ContentBox will work with all industry participants to build a new decentralized digital content platform.

Project Introduction

The ContentBox platform aims to build a blockchain-based community ecosystem for the future digital content industry. Based on ContentBox, the digital industry will usher in three revolutionary changes: shared content pool, shared user pool, and a unified payment system.

Different from traditional open communities such as the App store or WeChat open communities, ContentBox is a completely decentralized, autonomous platform driven by the open source community. ContentBox will help users share digital content on various web and mobile terminals in a more active way and bring a fast transfer system that does not require third-party participation.

In principle, ContentBox is committed to benefiting all content industry stakeholders, including but not limited to content creators, consumers, advertisers, distributors and application developers. In this ecosystem, these stakeholders can create, participate, collaborate and innovate on a fair and open digital content platform.

Project Vision

ContentBox is committed to benefiting all content industry stakeholders, including but not limited to content creators, consumers, advertisers, distributors and application developers. In this ecosystem, these stakeholders can create, participate, collaborate and innovate on a fair and open digital content platform.

For content creators, whenever their works are consumed by users, they will receive corresponding rewards provided by the payment system, thereby incentivizing them to create more high-quality works, and those creators whose works are extremely popular There will be huge rewards. In addition, ContentBox realizes the simplification and automation of platform transaction procedures, content creators and fans can directly trade without intermediaries.

For consumers, they will be rewarded based on their personal contributions to the community, including sharing, commenting, voting...even reporting spam, as long as these behaviors are beneficial to the community, they can use the obtained tokens to consume content, such as Watch a movie or download a song. Facts have proved that when the development prospects of the community are directly related to users, they will invest more money and energy in its management and publicity. The rise of the Bitcoin community is a good proof.

Advertisers can of course also benefit from this new ecosystem. Traditional advertisers calculate revenue based on data reports released by publishers, but ContentBox provides a shareable advertising statistical ledger, and the system will automatically pay advertising fees in the form of smart contracts according to the actual number of advertising views. Because the distributed ledger is completely open, advertisers can independently check the ledger at any time. This model can help them build an overall and unified marketing strategy, instead of doing many promotional activities on different platforms at the same time. In addition, they can also use tokens to launch bounty programs to reduce costs.

For distribution platforms and social networks, they can jointly build a shared content and user distributed ledger, which will benefit everyone by reducing the cost of paying search engines and IP purchase costs. They can focus on enhancing the user experience instead of competing with other platforms.

For APP developers, they can use ContentBox's blockchain token, decentralized payment foundation, and identity services to build applications with better user experience and stronger monetization capabilities.

To sum up, by changing the rules in today's digital content industry, the entire industry, including all stakeholders, will thrive due to cooperation and transparency. This will usher in a new era of content economy. In order to foster partnerships with all stakeholders, ContentBox will issue a token called BOX, which will play a key role in the community economy.

Project Highlights

Castbox is one of the most popular audio platforms in the world, ranking third in News & Magazines on the Google Play Store after TopBuzz and Twitter. Based on the industry-leading audio search system, Castbox recommends desired audio and audiobooks for podcasters and listeners. Now the team has grown to more than 50 people, with offices in Beijing, San Francisco, New York and Hong Kong.

Castbox was founded by former Google employees in early 2016. It has collected 50 million audio programs from more than 130 countries and regions around the world, and was awarded the best app in Google Store in 2017. In October 2016, Castbox was named the world's top trending app on Google Play, and won a host of other awards. Castbox is listed as an Editors' Choice app on Google Play in 135 countries.

Technical Overview

The nature of the digital content industry determines the need to create a tailor-made blockchain system.

• High frequency. The digital content industry is very different from traditional e-commerce in terms of payment and activity frequency. Normally, an ordinary person will not transfer money or buy or sell goods multiple times in a day. But on digital content platforms, it is very common for a user to download a song, watch a movie clip, or tip an author for an article within a few minutes. Without a doubt, we expect greater transaction volume in the world of digital content serving millions of users. And this requires the underlying blockchain system to be able to handle hundreds or even thousands of transfers per second.

• High requirements for privacy protection. Public chains like Ethereum are attractive in part because of their transparency: all smart contracts are publicly stored on each node and are independently audited. However, users on digital content platforms are more inclined to make anonymous transfers. A podcaster doesn't want to see his revenue information go somewhere unrelated to the transaction. For competitive and regulatory reasons, privacy is more important for business user transactions. Beyond that, as the events of DAO3 and Parity4 have revealed — the visibility of increasingly complex smart contracts poses serious security risks.

• Pervasive micropayments. It is foreseeable that most content transfers will be in small denominations. For example, users tip content creators a small amount, or purchase premium content such as an episode of a popular TV show. The industry needs a seamless micropayment solution to build a healthy and vibrant community. And this means that the transaction fee of the blockchain should be reduced to a minimum, or even zero rate.

Obviously, mainstream blockchains like Bitcoin and Ethereum are currently not a perfect fit for the digital content industry. Therefore, finding a new solution to build a lightweight and scalable blockchain is the only way to solve the above pain points. Admittedly, many emerging projects claim they can solve the above problems, but none of them have been proven to have a mature product launched, or enough users and developers to form a scalable, self-growing ecosystem. To address the above challenges, we propose an architecture consisting of three main components:

• BOX Payout . A secure and fast blockchain system for carrying multi-party secure payment services across applications
• BOX Passport . A unified identity authentication system based on blockchain across applications and platforms.
• BOX Unpack . A solution to help small and medium enterprises quickly and easily build a one-stop content management solution.

Application scenario

Mobile wallet

A lightweight wallet will be integrated into the Castbox application. When a user uses the APP, he can quickly check the account balance and transfer records through the built-in wallet. In the future, this wallet will display balances across apps.

As a popular mobile app, Castbox is the logical host of a BOX token mobile wallet. By allowing millions of users on Castbox to log in and create an instant online ecosystem, ContentBox will avoid the embarrassing situation of most start-up public chains when no one cares about them. In addition, because Castbox is an APP that users use frequently, most users will naturally interact with ContentBox multiple times a day and gradually establish the concept of cryptocurrency. In the long run, when users have a good experience in using BOX token and benefit a lot in the new blockchain system, they will promote the emergence of other applications developed based on ContentBox, thus Increase and expand the number of users in the community ecology.

BOX Login

When the Box Passport system goes online, Castbox will migrate compliant accounts to the blockchain system and give users a secure and universal BOX ID. By the time the migration is complete, Castbox's backend servers will no longer be storing user account and credential information. Instead, the app client will access the blockchain system to retrieve and verify the user's identity during the user's login process.

There are many benefits to using Box Passport not only for the end user, but also for the operator of Castbox. Since the heavy responsibility of verification and authorization has been transferred from the App server to the public chain, the operator no longer has to bear the high labor cost of protecting user information from hackers. On the other hand, users can also gain control over their own data, thereby reducing the risk of personal information leakage.

In-app reward system based on BOX token

In addition to the lightweight wallet, a token reward system will also be embedded in Castbox. This reward system mainly includes two goals: to use material means to motivate authors to create more valuable content and to encourage users to manage and spread high-quality content. For example, a listener finds an interesting podcast on Castbox, writes a comment and shares it with friends in social networks (such as Facebook and Twitter), and in return, he will receive some BOXToken.

Users can also help filter swipes to get tokens. Troubleshooting is a challenge for every online community. If it cannot be effectively controlled, it will greatly reduce user experience. Usually, digital content platforms solve such problems by hiring a large number of supervisors or investing in the development and deployment of AI artificial intelligence algorithms to automatically filter water stickers. But all these approaches are not only inefficient but also costly. Through the built-in incentive system, Castbox users will actively report useless content to get rewards.
