As an AMM, Diffusion leverages decentralized liquidity pools instead of using a traditional limit order book to facilitate trades. Please see more information on the core AMM design under Liquidity Pools.
The second core piece differentiating Diffusion from traditional markets is the permissionless design of the protocol. The protocol’s services are entirely open for public use. The team has no ability to selectively restrict access. Anyone can swap, provide liquidity, or create new markets at will.
