# About Demex ## What is Demex? [Demex](https://dem.exchange/) (a.k.a. Decentralized Mercantile Exchange) is a decentralized L1 platform built from the ground up to support a fully on-chain financial system. Every action is visible on-chain, and it supports up to 50k orders / second with a 1.6s block finality time. Demex uses a custom consensus algorithm based on [CometBFT](https://docs.cometbft.com/v1.0/), as well as a proprietary oracle P2P protocol that allows data feeds of any asset to be updated to the L1 within 1 second. Our vision is to be able to support any financial need a person may have. Demex already supports on-chain order book trading (spot, perpetuals, futures), lending & borrowing, and earning via staking & liquidity pools. Demex will be launching options trading soon. ## Why Demex? Demex is unique as it has: * **Deep Liquidity -** Demex spot and perpetual order books are backed by liquidity vaults and AMMs. This means very deep liquidity and virtually zero slippage on all markets. * **CEX Speed Trading** - With a 1.6s block time, Demex finality is 400x faster than Ethereum, and comparable to the latest Layer 2 chains. Trading on Demex is virtually indistinguishable from a CEX. * **One-stop Shop** - Demex supports many types of instruments rather than just one (e.g. perps). This means you can deposit once and do everything you need on Demex. * **Capital Efficient** - Multi-collateral trading will allow lending positions and non-stablecoin assets to be used as margin. Together with support for long tail assets, Demex is the most capital-efficient trading venue. * **True Fairness** - Demex's trading engine is MEV-resistant - all trades within a block are treated with the same time priority and are fairly matched with a single clearing price. There is no centralized sequencer, and there are 10+ non-team validators active. * **True Openness** - All transactions are on-chain and final. Users can also list any token and create any market permissionlessly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
