Osmosis (OSMO) is a decentralized exchange (DEX) for [Cosmos](https://www.coinlive.com/coin/cosmos), an ecosystem of sovereign, interoperable blockchains all connected trustlessly over IBC, [the Inter-Blockchain Communication Protocol](https://ibcprotocol.org/). Osmosis also offers non-IBC assets bridged from the Ethereum and Polkadot ecosystems. Originally based on Balancer-style pools, Osmosis is moving to a more sustainable [concentrated liquidity](https://docs.uniswap.org/protocol/concepts/V3-overview/concentrated-liquidity) model that provides a superior trading and liquidity provision experience.
As an [appchain DEX](https://medium.com/nascent-xyz/the-inevitability-of-unichain-bc600c92c5c4), Osmosis has greater control over the full blockchain stack than DEXs that must follow the code of a parent chain. This fine-grained control has enabled, for example, the development of [Superfluid Staking](https://www.coinbase.com/cloud/discover/insights-analysis/what-is-superfluid-staking), an improvement to [Proof-of-Stake](https://coinmarketcap.com/alexandria/glossary/proof-of-stake-pos) security. Superfluid staking allows the underlying OSMO in an LP position to add to chain security and earn staking rewards for doing so. The customizability of appchains also allows for the development of a transaction [mempool](https://coinmarketcap.com/alexandria/glossary/mempool) shielded with [threshold encryption](https://eprint.iacr.org/2022/898), which will greatly reduce harmful MEV on Osmosis.
Osmosis's vision is to build a [cross-chain](https://coinmarketcap.com/alexandria/glossary/cross-chain) native DEX and trading suite that connects all chains over IBC, including Ethereum and Bitcoin. To build out the trading functionalities, Osmosis has invited external developers to create a bespoke [DEX ecosystem](https://osmosis.zone/ecosystem) that includes lending, credit, margin, fiat on-ramps, Defi strategy vaults, NFTs, stablecoins, and more – all the functionalities of a centralized exchange and more, plus the trust-minimization of decentralized finance.
