CIP0-Contentos Improvement Proposal Guide

Contentos is an ongoing project that is empowered by the Contentos Foundation and the community. To facilitate the Contentos blockchain and ecosystem in adapting to the needs of DApps, Block Producers, and Users, we are planning a mechanism that will allow every stakeholder to express their ideas and to reach consensus through discussion and majority vote.


A Contentos Improvement Proposal (CIP), is a design document providing information to the Contentos community, describing how the Contentos blockchain and ecosystem could be improved and the rationale for the proposed modification. A CIP must be filed in this forum (优化提案) along with a “make proposal” transaction made by a block producer. Currently, there is no defined format for a CIP. However, please note that a comprehensive CIP will make it easier for the community to understand why and how the proposal could bring overall benefits to the Contentos ecosystem. For details on the “make proposal” transaction process for block producers, please refer to the “proposal” contract document (

Proposal Validation

Once a CIP is posted, the Contentos Foundation will check if the document and the corresponding “make proposal” transaction are valid. The validation results will be sent to the CIP by an “admin” account. A voting schedule will also be provided within the reply, specifying a particular block height that block producers must vote on beforehand. In the future, we will transfer this authority to the community.

Majority Vote

Block producers and BP candidates that do not rank in the top-21, can cast their votes to a CIP. The voting result will be determined by majority vote by block producers at the exact block height specified in the proposal validation reply. The voting result will be sent to the CIP by the “admin” account. The result will consist of the decisions of each block producer and the corresponding “vote” transactions. For details on the “vote” transaction process for block producers and candidates, please refer to the “proposal” contract document (

Proposal Follow-up

Blockchain developers and/or other stakeholders of the CIP will take necessary actions in response to the voting result. The Contentos Foundation will facilitate the execution of the CIP if necessary.

About this Document

This document was composed by the Contentos Foundation as an initial guide to the decentralized governance of the Contentos blockchain and ecosystem. Should there be any suggestions regarding the proposed process and this document, please file a CIP to propose the suggested improvements.



Contentos優化提案Contentos Improvement Proposal,簡稱CIP,是提供給Contentos社群的設計文件,指出Contentos公鏈及生態可以如何優化並說明合理的原因。一個CIP文件必須被發佈在此論壇(优化提案 ),並且由出塊節點發起「make proposal」交易。目前,CIP文件沒有特定的格式規範,然而,一份詳盡清楚的CIP文件有助於其他人理解這個提案對於Contentos生態的整體益處及如何實行。關於出塊節點如何發起「make proposal」交易,請參閱「proposal」智能合約的相關文件:


CIP文件發佈後,Contentos基金會將確認文件與對應的「make proposal」交易是否有效。驗證結果將由「admin」帳號回覆在CIP文件下方,並且載明適當的投票安排,出塊節點必須在給定的區塊高度到達前,投票作出對於此提案決定。未來,提案驗證的工作將由基金會交由社群運作。

How can a developer benefit from the contentos public chain? | 作为开发者如何从contentos公链中获取利益?

Rewards for supporting the technical and ecosystem development of Contentos

  1. SDK Development: Developers can earn up to 50,000 COS tokens by developing Python-SDK, Flutter-SDK, or PHP-SDK. For other kinds of SDK development reward, please stay tuned.

  2. Block Producer Election: For developers familiar with Contentos public chain, you may build your own node and try to receive enough votes to become a block producer. Each block producer is expected to receive at least 350,000 COS block producing reward every year.

  3. Wallet Development: iOS, Android, or web-app wallet developers can receive 200,000 COS rewards if the wallet becomes officially adopted.

  4. DApp Development: A good DApp(such as or PhotoGrid) can stimulate users to create more high-quality contents. When the content won ecological rewards, the developer can get 10% of the ecological rewards while creators can get 90% of it. For example, if a creator gets 1000 COS awards through your DApp, the developer can take 100 COS from it. In addition, the Contentos Foundation would distribute some of its 500 million COS Dapp-startup pool to key collaborative DAPP partners.

  5. Bug and Vulnerability Bounty: The R&D team will reward developers with 1,000 to 500,000 COS, or equivalent USDT, for reporting bugs or security vulnerability. The exact amount of reward will depend on the severity of the issue reported.

  6. For other development suggestions, reply directly or email You may receive COS rewards if your ideas are adopted.

Don’t hesitate to let us know if you have questions from any of these programs. We look forward to your participation!

  1. 开发各种sdk,目前计划中的python-sdk, flutter-sdk, php-sdk均能获取5万COS代币的奖励

  2. 对于COS公链比较熟悉的开发者,可以自己搭建节点,获取用户选票后成为出块节点,每个出块节点每年有至少35万COS的出块奖励

  3. ios/android/web端的钱包开发,如果被官方采用,则会得到20万的cos奖励

  4. dApp的开发(功能类似于 或者 photogrid ),能够从创作者身上抽取10%的生态奖励,例如一个创作者通过你开发的dApp拿到了1000个COS的奖励,那么dApp的开发者会从中分走100个COS。另外contentos基金会也从5亿dapp启动奖励池中分配一些给重要的合作dapp伙伴。

  5. BUG回报,研发团队会针对bug的严重程度奖励开发者1,000 至 500,000 COS或者等值的USDT

  6. 如果有更好的开发建议,可以发送邮件至 或者直接回帖,建议被采纳后,依然能获取到COS奖励
