Sei DeFi Ecosystem Guide

Sei operates as a Layer 1 blockchain that merges characteristics of Ethereum and Solana: leveraging Ethereum's established development framework alongside Solana's transaction throughput capabilities. The V2 iteration of Sei introduces the first parallelized EVM implementation, establishing a novel scaling methodology for the Ethereum network. The platform began operations with its mainnet activation in 2022 and has developed a substantial ecosystem drawing developers and teams previously working with Ethereum, Solana, Polygon, Arbitrum, and comparable networks. The project receives backing from prominent investors including Multicoin, Jump, and Coinbase Ventures. Jayendra Jog and Jeff Feng serve as the protocol's co-founders.

Overview

Sei's foundational principle centers on a specific thesis: the primary function of blockchain networks is facilitating the exchange of digital assets. Consequently, developing efficient scaling mechanisms for asset exchanges represents a critical requirement for advancing Web3 adoption to the next level. Sei functions as an open-source, multi-purpose Layer 1 network specifically engineered for trading activities, with all components of its technical infrastructure optimized to deliver superior systems for digital asset transactions.

The network's public mainnet became operational on August 16, 2023, followed by the launch of its public devnet on February 13, 2024.

Sei V2 EVM

Sei's second version introduces numerous innovations, including high-performance parallelized EVM functionality. These enhancements enable a blockchain that synthesizes optimal features from both Solana and Ethereum ecosystems, improving transaction experiences and establishing novel opportunities for development work, with enhanced transaction processing rates relative to present Ethereum ecosystem alternatives.

2025 SIP-3 Update

Sei has initiated a migration toward an EVM-focused infrastructure following community approval of SIP-3 via governance mechanisms. This proposal specifies the discontinuation of CosmWasm and traditional Cosmos-based transactions, replacing them with a unified EVM-based system architecture. The objective involves streamlining the development experience and strengthening Sei's connection with the EVM ecosystem while retaining its high-performance attributes.

Important considerations that arose during community consultation include migration assistance for established CosmWasm applications, protocols for managing asset transfers, updated technical specifications for EVM system calls, requirements for running nodes and data retrieval infrastructure, and more transparent messaging regarding consequences for assets. Significantly, only CosmWasm-based assets will need to transition; EVM-based assets will remain unaffected. The process will unfold sequentially across multiple stages with predetermined milestones.

• Compatible EVM Infrastructure: This functionality enables developers from the Ethereum community to transfer their applications, development tools, and network infrastructure onto Sei without modification, while gaining access to Sei's 100x performance enhancements. The blockchain continues offering CosmWasm support as an alternate execution layer operating on the identical network.
• Concurrent Transaction Processing: This mechanism enables developers to activate simultaneous execution pathways for their code automatically, requiring no extra implementation effort. This approach mirrors Solana's throughput scaling methodology; Ethereum-focused developers can now implement concurrent processing approaches for the first time.
• SeiDB: This substantial enhancement permits Sei to accommodate considerably greater volumes of information storage, retrieval, and modification operations that become essential for rapid blockchains. Beyond delivering substantial performance gains for coders and particularly node maintainers, it enables expedited synchronization and decreases resource demands by preventing excessive blockchain data expansion.
• Twin Turbo Consensus: This system permits Sei to accomplish the quickest completion time across all blockchains at 390ms, making possible experiences comparable to traditional internet applications for blockchain-based systems.
• The Parallel Framework: This represents a comprehensive, publicly accessible toolkit created for developing secondary layers and compressed variants that capitalize on concurrent processing capabilities, offering a design approach specifically engineered to substantially improve the Ethereum network, specifically tackling the performance constraints that compressed Ethereum networks currently experience.

Main Features

Sei incorporates multiple significant capabilities to strengthen its operations. Protection represents a primary emphasis, with Sei engaging with international organizations and network validators to guarantee strong security frameworks for digital asset transfers. The design framework emphasizes expandability, responding to rising interest in decentralized services and facilitating worldwide major platforms effortlessly. The system's flexibility enables it to grow in line with sector changes, with decentralized governance directing enhancements. Velocity is highlighted to facilitate rapid transactions without compromising integrity and dependability. Furthermore, Sei prioritizes sustainability by implementing proof-of-stake validation to decrease its energy footprint, advancing a more environmentally conscious digital asset sector through carbon offset initiatives coordinated by the Sei Foundation.

Technology

Twin-Turbo Consensus

Sei implements the Twin-Turbo Consensus framework to strengthen transaction throughput. This technique enhances transaction propagation procedures, dispersing transactions originated by participants throughout the network infrastructure. Network operators incorporate these transactions into their processing queues, and network participants generate block suggestions containing transaction identifiers and comprehensive block data. This methodology minimizes communication delays, shortens validator latency, and strengthens Sei's overall system performance.

Optimistic Block Processing

Sei incorporates Optimistic Block Processing, a novel mechanism enhancing transaction throughput. Rather than delaying transaction analysis until later processing phases, as occurs in standard approaches, Sei starts analyzing transactions immediately upon receiving block recommendations. This procedure generates a provisional ledger state maintained temporarily and made permanent following successful block confirmation. This simultaneous approach minimizes delays and quickens processing capabilities, strengthening Sei's processing effectiveness.

Parallelization

Native Order Matching Engine

The Native Order Matching Engine serves as infrastructure for decentralized market platforms operating within Sei. This system facilitates establishing and administering Central Limit Order Books (CLOBs) throughout the Sei ecosystem. Through incorporating order books at the blockchain level, decentralized market platforms can effectively launch and manage trading pairs, furnishing market participants with superior trading capabilities.

On April 4, 2024, the Sei Foundation, a nonprofit organization dedicated to strengthening the Sei ecosystem, introduced the Sei Creator Fund, allocating $10 million in development resources for launching novel applications and expanding established NFT and community-driven initiatives within Sei.

This financial allocation reflects recognition of expansion within the Sei user community, intended to help grow Sei's NFT and community-centered infrastructures.

> The Sei Creator Fund aims to encourage creators and programmers working across the complete spectrum of NFT and community domains: digital collections, platforms, backend systems, original works, and even physical community gatherings.

Various applications and organizations contributing to the Sei NFT ecosystem have obtained grants from this fund. The Sei Creator Fund targets assisting diverse applications and groups across varying levels of maturation and development stages.
