How developers can claim missions

Release of missions

At 11:00 (GMT+8) on every Monday, IOST will update the missions on its Slack developer community. These updates will be synchronized on IOST’s Telegram group (English and Chinese channels), Medium (English and Chinese channels), and Github.

By filling out this application form, developers can claim missions. Once submitted, the IOST team will contact the applicants.

Bounty mechanism for referrals

IOST has also set up a bounty mechanism for referrals. People can recommend qualified developers to IOST and claim a referral bounty. Once the projects are completed by the recommended team, the referrer will receive 3% of the total budget for the project’s development.

Mission rewards

The amount of rewards will be determined by period and complexity of each project.

Mission progress and completion

At 18:00 every Friday (GMT+8), IOST will collect information of development progress for each project and reward developers for completed bounties. Developers need to inform IOST about their progress before 18:00 Thursday (GMT+8) to be qualified for project review and payment.

Updates of development projects will be published on Slack, Telegram (Chinese and English channel), Github.

Developer ranking mechanism

After performance evaluations of each development project, developers will be scored and ranked. These scores will then be used to weigh applicants. Developers who repeatedly complete high-quality projects will have a higher chance for long-term collaboration with IOST and receive higher rewards.

Performance will be evaluated and ranked at 18:00 (GMT+8) at the end of each month. The top three developers by rank will be rewarded with “Elite Developers” status and gain other IOST special gifts.

Quality control and risk management

Once the project is submitted, the team will review the quality of each project. If a developer/development team encounters problems which may cause delay to deadlines or cannot continue the development, the developer/ development team needs to inform IOST in advance and explain the situation. Uncompleted projects will not be rewarded.

Once the project is submitted, IOST owns full copyrights and developers/ development teams cannot use the projects and their contents for other commercial uses.

Developers interested in IOST’s bounty program can see all the latest missions and work with IOST by joining IOST’s groups on SlackTelegram or by following IOST’s official account on Medium.
