What Is Sei? A Guide to the High-Speed Layer 1 Crypto Network

In the rapidly evolving digital landscape, Sei emerges as a formidable Layer 1 crypto network, offering solutions that enhance blockchain speed and affordability. Whether you're engaging in token swaps, minting NFTs, or developing decentralized applications, Sei provides a robust platform tailored to meet these demands efficiently.

Intrigued by how Sei distinguishes itself in the competitive blockchain arena? Join us as we delve into its sophisticated architecture, unique features, and the dynamic ecosystem it supports.

What Is Sei Network?

Sei Network is an open-source, Cosmos-based Layer 1 blockchain engineered to accelerate decentralized trading and NFT marketplaces. It delivers a seamless infrastructure for developing decentralized applications (dApps), emphasizing both speed and cost-effectiveness.

Key Highlights:

  • Advanced EVM: Sei boasts one of the fastest Ethereum Virtual Machines (EVM), enabling developers to scale their projects while maintaining compatibility with Ethereum's extensive infrastructure.
  • Scalability: Ongoing enhancements aim to increase blockchain throughput, unlocking new possibilities for developers and reducing operational costs for users.
  • Founders: Led by Jeffrey Feng, a former tech investment banker at Goldman Sachs, and Jayendra Jog, a former Robinhood software engineer, Sei Labs is based in San Francisco.

Sei Under the Hood: How Does the Sei Network Work?

Sei addresses blockchain challenges such as network congestion and security by prioritizing speed and efficiency without compromising safety. Below are its groundbreaking features:

Twin Turbo Consensus 

Central to Sei’s performance is the Twin Turbo Consensus, an evolution of Cosmos’ Tendermint consensus mechanism. While Tendermint provides a 6-second finality, Twin Turbo significantly reduces this to under 400 milliseconds by:

  • Eliminating Validator Wait Times: Validators no longer need to wait for all relevant data before finalizing transactions.
  • Optimized Block Propagation: Enhanced methods ensure faster block processing.
  • Optimistic Block Processing: Increases efficiency by anticipating block validity.

These advancements result in near-instant block finality, positioning Sei among the fastest blockchains and delivering "Web2-like" responsiveness to decentralized applications.

Parallelized EVM Stack

Sei introduces the Parallel Stack, an open-source framework designed to:

  • Scale EVM: Supports parallel processing, enabling higher performance and scalability.
  • Facilitate Layer 2 Solutions: Developers can build more efficient Layer 2 chains and rollups, reducing fees and enhancing user experience.

Web3 developers are increasingly interested in parallelized virtual machines (as opposed to single threaded ones), which have better performance and scalability. 

Parallel Stack is a powerful open-source framework for building Layer 2s and rollups with parallel processing, resulting in lower fees and better user experiences.Parallel Stack allows projects to utilize Sei’s validator set for sequencing on their Parallel chains. Lastly, as a developer, you can opt into leveraging Sei’s validator set for sequencing.

Built-in Order Matching Engine

Sei’s Order Matching Engine transforms order placement and matching through:

  • Central Limit Order Book (CLOB): Offers a transparent, scalable, and cost-effective trading system.
  • Parallel Processing: Manages independent orders simultaneously, accelerating transactions across various markets.

The Order Matching Engine has numerous applications across spot trading, derivatives, and betting markets. The engine processes by matching independent orders (i.e. orders in different markets) in parallel at the end of the block, instead of processing orders sequentially. 

Sei v2: The Next Evolution

With the Sei v2 upgrade, Sei Labs introduces a suite of new features that enhance the network's capabilities:

  • Dual Execution Environments: Supports both CosmWasm smart contracts and EVM, leveraging Sei’s optimized architecture.
  • Enhanced Token Standards: Implements all Ethereum token standards (e.g., ERC-20, ERC-721) on Sei.
  • Increased Throughput: Capable of handling over 5,000 transactions per second, with potential scalability up to 12,500 transactions per second.

With SEI v2, Sei tries to take user experience to a whole new level and establish an entirely fresh and improved design space for developers. This space now features enhanced scalability and developer flexibility. According to Sei, it also boosts throughput by 100x in comparison to the competition.

Unraveling the SEI Tokenomics: Here’s What You Should Know

The Sei Network has its own token called SEI. You can use the utility token for all sorts of things, including paying for network fees, delegating holdings with validators, or staking it to run one’s own validator for securing the network, in governance, and as native collateral–just to name a few. 

Its allocation assumes 48% in the ecosystem’s reserve (staking rewards, ecosystem initiatives, in addition to SEI airdrops and incentives), 20% distributed to investors in private sales, 20% going to the core team, 9% to the Sei Foundation’s Treasury, and 3% intended for the Launchpool.

SEI’s market cap hovers near $1.8 billion, with a total supply of 10 billion SEI, and 4.2 billion SEI currently in circulation.
