B-Protocol, a decentralized backstop liquidity protocol, where backstop liquidity providers (BLP) buy their right to liquidate under-collateralized loans and share their profits with the users of the platform. As a result, the users (borrowers and lenders) receive additional yield to their usual interest rate. The proposed mechanism eliminates the need for gas wars between liquidators, and thus transfers a big part of the protocol value back to the borrowers and lenders, which in turn improves their effective interest rate.
