Monthly highlights: - Announcing iBFT (intelligence Byzantine Fault Tolerance) - COS Quiz Airdrop About Contentos: Contentos aims to be a decentralized global ecosystem for digital contents, where contents can be freely produced, authorized, transacted, and distributed by leveraging blockchain technology and token economy. The team consists of experts from content industry, top-tier app developer, and blockchain projects. Contentos not only is a blueprint toward a better digital content world but has already been integrated into products with more than 60 million global monthly active users from partnership with Cheetah Mobile and LiveMe. By getting real feedback from users while developing its underlying blockchain mechanism, Contentos is to be one of the most user-oriented blockchain projects.

1. Reinvent the Global Content Value Ecosystem

3. ContentOS, a content OS based on blockchain technology
Spanish "Happy", we want to bring happy to global creators
COS is the name of token

4. Digital Content Industry Status
Attention

5. Attention Influence
• Centralized platforms control audience interest
• Centralized platforms control creators’
viewership and monetization
• Centralized platforms control the payment
gateway
• Everything is calculated by a fiat currency
making cross-country content purchasing
difficult
Existing Way of Exchanging “Content Value”
The value of content creation came from exchanging an
audience’s “attention” for a creator’s “influence”
Audience Creator
Creator generates
"influence" when
creating content
Audience

"attention"
when viewing
content

6. Attention Influence
Token Economy
Peer-to-Peer Content-Value Exchange
Contentos aims to redefine the “content-value exchange” with
decentralized technology and token economy

Can It Be Faster?
Time for Confirming a Transaction

18. Transaction Confirmation
• Required time to reach none-reservable status among block
producers (“nodes”)
• The goal of every consensus mechanism
• Require node’s and network resource consumption
• Transaction confirmation speed relates to many other factors such as
chance to generate soft fork or give more pressure to the network

19. Can Consensus Mechanism Dynamically
Adapt The Present Transaction Volume Need?
• How to Speed up the Transaction Confirmation during Low
Transaction Volume Period
• How to Reduce the Resource Consumption in Network
during High Transaction Volume Period While Maintaining
Reasonable Confirmation Speed
