Reinvent the global content value ecosystem

5. What are you planning to achieve with your project?

The vision of Contentos is to build a decentralized, global digital content community that allows content to be freely produced, distributed, rewarded, and traded, while protecting author rights. Contentos will incentivize content creation and global diversity and return the rights and value of content to its users.

Contentos has these key features:

Content industry-optimized public chain : To better support the massive interactions of content community, Contentos is building its own underlying blockchain optimized specifically for content industry. The implemented saBFT, self-adaptive Byzantine Fault Tolerance, consensus mechanism enables zero-fee transaction and shrinks the block confirmation time down to 1 second. (more about saBFT)

Some similar approaches were carried out in other content-based projects but have exhibited problems such as the reward are mainly dominated by senior users with massive tokens. Contentos is tuning the model based on the actual data collected from TestNet integrations.

Open platform: Covering 60 million potential users, Contentos is proactively reaching out to Dapps across different blockchains. The cooperation with mature apps like PhotoGrid and LiveMe made it easy for Contentos to introduce non-crypto users to the blockchain world and start using the partnered Dapps. With account and token integration, the open platform initiated by Contentos can benefit even the whole blockchain industry.

Development

1. What are the technological innovations of the project, if there are any?

Contentos deploys a novel BFT+DPoS based consensus protocol called saBFT (self-adapting BFT). The key contribution is to separate the BFT voting process from the block-producing process. Unlike other BFT family protocols, we run BFT and block-producing asynchronously so that blocks could be committed in batches. It helps overcome network jitters and achieves statistical shorter finality delay without loss of safety and liveness.

2. Where are your code repositories located?

Contentos is fully open-sourced on GitHub. https://github.com/coschain

3. Do you have any products or UI demos can you share publicly? Are any built by your community, as opposed to being in-house demos?

Since Contentos launched its TestNet on 3/27, 4 Dapps were integrated and helped Contentos verify its public chain implementation with substantial real users. You can find all Dapps daily statistics in Contentos block explorer, DApp section. Current TestNet v0.3 has over 38K on-chain addresses, average 7K on-chain daily active users (DAU) and over 45K daily TX, these data result has been achieved within 8 days since June/10 TestNet v0.3 went live and all on-chain test data has been reset from that day.

4. Do you plan to release weekly progress updates in this forum?

We currently release monthly updates on Medium, Telegram, Twitter, and Facebook. We are happy to provide them here as well. Monthly report for the past one year can be found on contentos.io website, section: Project Reports.

5. Do you plan to host monthly or bi-monthly video AMAs?

Not yet planned. But it’d be helpful for our community to stay in sync. Contentos team also conducted regularly monthly local meetups such as Vietnam, Taiwan, South Korea and Japan. Meetup recap can be found in monthly reports.

Competitors

1. Who do you view as your current competitors/peers?

Centralized content platform: YouTube, Twitter, Facebook, Instagram

Decentralized content platform: Steem, Theta Network

2. What is your project’s competitive advantage over existing or potential future solutions?

Compared to centralized content platform, Contentos provides direct channel for value exchange without platform as the middleman and non-transparent revenue sharing. In addition to developing content industry-optimized blockchain, Contentos established strong partnership with existing major content apps and reached out to over 60 million potential users. The users are much more diversified and truly are the user of content, whereas some similar projects may only attract crypto users.
