Umbrella is not insurance in the typical sense. The word is used loosely to help explain the concept. Umbrella uses the innovation of a crypto asset backed insurance system, or (CABI) for short. Half of each block reward is secured during the mining process and held as collateral for claims. Provided all the dotted lines have been signed, reimbursement is a painless process. After the beta ends, features will be fully automated and built into the wallet for a pain free experience.
