# Contribution value explanation What is contribution value Subtracting the performance of a large department, the sum of the performance of other departments equals the community performance. Community performance x reward multiple = contribution value For example: A invites B1 to bet 1000U, B2 to bet 1000U, and B3 to bet 2000U. Subtract the largest department B3, add other departments = 2000U, 2000U performance X multiple = contribution value. Reward multiplier Community betting amount × corresponding multiple The daily reward base of the reward pool is 0.8% Example: IDO/Ecology Total accumulated bets are 10 million ×0.8% per day = 80,000 USDT equivalent BTO --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
