The protocol is an insurance marketplace that is decentralized. It enables insurers/underwriters to launch insurance policies on-chain, protecting policyholders from risk and providing profit potential for liquidity providers.

Protocol participants include:

* Pool manager - underwrite policy, modify policy parameters, and submit claim
* Liquidity provider - As a liquidity provider, you can deposit collateral and earn a yield.
* Policyholders - Purchase insurance policies and pay premiums.
* Committees - vote on a claim, and propose and vote on a manager or committee member change.
