Regarding technical details, limited to the limited number of publicly available information, and based on the reader’s convenience in reading, the author does not want to repeat them too much. On the one hand, these are not highly relevant and relevant to the public. On the other hand, the central bank digital currency is important for public chains and The technical reference of the alliance chain is not large (in terms of security and stability, the central bank's digital currency will definitely adopt the most conservative and the least innovative design plan).

DAI is used as collateral, CLAIM represents the claim right of the insurance demander, NOCLAIM represents the right of the insurance provider, and COVER is the governance token. 1CLAIM token + 1 NOCLAIM token ≈ 1 collateral, if a claim occurs, 1 CLAIM token ≈ 1 collateral, NOCLAIM token is reset to zero; if no claim is due, 1 NOCLAIM token ≈ 1 collateral, CLAIM token is reset to zero . This formula is commonly used in prediction markets. For example, in the 2020 U.S. election, the sum of the probability of Trump and Biden being elected president is close to that when Biden is elected president, the tokens that predict Trump's election will return to zero. Through this simple design, COVER makes it easier for users to participate in decentralized insurance. At present, COVER's products have covered the latest BadgerDAO, BasisCash and other agreements, and have already achieved PickleFinance claims.
