Sei Network is the first L1 blockchain dedicated to the order book.

It is built using the Cosmos SDK and Tendermint core and has a built-in Central Limit Order Book (CLOB) module. Decentralized applications built on Sei can be built on top of the CLOB, and other Cosmos-based blockchains can use Sei's CLOB as a shared liquidity hub to create a marketplace for any asset.

-Sei's shared liquidity model. designed with developers and users in mind, Sei is the infrastructure and shared liquidity hub for the next generation of DeFi. Apps can easily plug and play, trade on the Sei order book infrastructure, and access pooled liquidity from other apps. To prioritize the developer experience, the Sei network has been integrated with the wasm module to support CosmWasm smart contracts.

Why choose Sei?

-Sei supports CosmWasm smart contracts and integration with other IBC chains

-Sei is a Layer 1 blockchain built specifically for the order book. The chain emphasizes reliability, security and high throughput, enabling new ultra-high performance DeFi products built on top.Sei's on-chain CLOB and matching engine provides deep liquidity and price-time-priority matching for traders and applications. Applications built on Sei benefit from a built-in order book infrastructure, deep liquidity and a fully decentralized matching service. Users benefit from this exchange model with the ability to choose price, size and trade direction with MEV protection.

-Smart Contracts.Sei leverages the wasmd module to make it easy for developers to build on Sei. Developers can use the Rust-based CosmWasm library to create decentralized applications. This provides developers with multiple advantages.CosmWasm is mature and used by many chains. Therefore, it is stable and has a large developer ecosystem.CosmWasm was built to solve many of the development problems faced by other ecosystems. It is easier than developing on Solana and offers better security than Solidity.

-DEX module

Sei has created a new dex module that allows Cosmwasm smart contracts to use the underlying CLOB for deep liquidity.

Central limit order book

Combines on-chain security and decentralization with off-chain speed and efficiency. Most financial applications in traditional finance use CLOBs to create markets. This works well if you have cheap transaction fees and lots of liquidity. However, in decentralized finance, the automated market maker (AMM) model is more popular because it doesn't require constant order updates and works with less liquidity.

Sei offers cheap transaction fees and works with market makers that have a lot of liquidity. As a result, it can offer an order-based trading experience in a decentralized, permissionless manner. This frees up many use cases that previously could not work with the AMM model.

Sei Ecosystem

Sei enables ultra-high performance DeFi applications.The Sei network is an L1 blockchain with a built-in on-chain order book that allows smart contracts to easily access shared liquidity.The Sei architecture enables composable applications that remain modular.

The Sei network serves as the matching core of the ecosystem, providing superior reliability and ultra-high transaction speeds for ecosystem partners, each with their own functionality and user experience. Anyone can create a DeFi application that leverages Sei's liquidity, and the entire ecosystem benefits.

Developers, traders and users can all connect to Sei as ecosystem partners, benefiting from the shared liquidity and decentralized financial primitives.

Why choose cosmos

Cosmos is an ever-expanding, ecosystem built for a decentralized future. Developers can use Cosmos to create completely independent application-specific blockchains that can seamlessly interconnect. Interoperability, autonomy, collaboration and innovation are the most important things that make Cosmos the blockchain internet.

The Sei network is uniquely positioned to help the next generation of new users join the Cosmos ecosystem.Sei leverages the Cosmos SDK and its focus on horizontal scaling to create an extremely developer-friendly environment. Using an order-specific blockchain, developers can create high-performance and capital-efficient DeFi applications that can be enjoyed by users around the world. This combination of high quality dapps, deep liquidity and a best-in-class native bridging solution will create a flywheel effect that will allow the entire Cosmos ecosystem to grow.

Advantages of using cosmos: Cosmos SDK, CosmWasm, IBC

*Cosmos SDK

Cosmos SDK is an open source framework for building multi-asset public forensics (PoS). Its purpose is to allow developers to easily create custom blockchains from scratch and to interoperate natively with other blockchains. The SDK-based blockchain is built from composable, (mostly) open-source modules that can be used by any developer.

Features of the SDK include.

-Modularity, allowing customization of the blockchain to the user's specific requirements

-Scalability to run parallel chains

-Interoperability to communicate with other blockchains via the IBC module

-Security with access control firewall

-PoS module as a secure foundation

-Sovereignty to propose and vote on blockchain upgrades via the governance module

-Open source community

Take advantage of the Golang ecosystem to write dApps in Go.

CosmWasm

CosmWasm is a new smart contract platform built for the Cosmos ecosystem.CosmWasm is written as a module that can be plugged into the Cosmos SDK. This means that anyone currently building a blockchain using the Cosmos SDK can quickly and easily add CosmWasm smart contract support to their chain without having to tweak existing logic.Smart contracts on CosmWasm can run on multiple chains, leveraging the IBC protocol.

Features.

-Tight integration with Cosmos SDK and Cosmos ecosystem

-Secure architecture designed to avoid all attack vectors present in Ether

-Proven tools for developing and testing smart contracts

-IBC is being planned in parallel with the integration of Cosmos Hub.

IBC

IBC is used for reliable, ordered and authenticated communication between modules on separate distributed ledgers.IBC is unique in that it separates the "application layer" from the "transport and network layer". This means that IBC defines how data is sent and acknowledged between blockchains, but it does not define what that data is or how it should be structured. This makes IBC different from other interoperability solutions that require more standardization at the application layer.
