Sei: Redefining Web3 Product Architecture

·

Blockchain technology and its ecosystem have opened numerous opportunities for innovators, developers, and users. However, scalability, transaction speed, and front-running issues have hindered Web3's mass adoption. Sei emerges as a solution to these challenges.

This article explores Sei's superior mechanisms through its foundational design, thriving ecosystem, comparative advantages over other Layer1 networks, and unique trading benefits.

Sei: Mechanism Overview

Sei is a universal Layer1 network designed to address common issues in blockchain systems. It operates via the Twin-Turbo Consensus mechanism, leveraging transaction parallelization for rapid finality, high throughput, and scalability. This bridges the gap between decentralization and performance.

Twin-Turbo Consensus

Sei is a high-TPS parallel Layer1 with a consensus model similar to DyDx’s Tendermint but with key optimizations:

  1. Intelligent Block Propagation:

    • Validators reconstruct blocks using transaction hashes from proposers, reducing synchronization time.
    • Missing transactions are fetched from fragmented block data, enhancing efficiency.
  2. Optimistic Block Production:

    • Validators process block data concurrently during prevote/precommit phases.
    • Cache integration skips serial waits, accelerating finality (~0.5 seconds).

Transaction Parallelization

Sei’s DAG-based (Directed Acyclic Graph) system distinguishes independent and interdependent transactions, enabling parallel processing for unrelated operations (e.g., order-book trades) while serializing linked actions (e.g., NFT mints).

MEV Prevention & Order Bundling

Built-in Oracle Pricing

Sei integrates oracle price feeds into consensus, with validators agreeing on asset prices per block for real-time accuracy.

FAQ

Q: How does Sei prevent MEV?
A: Via batch auctions that execute trades simultaneously at agreed prices.

Q: What makes Sei’s consensus unique?
A: Twin-Turbo combines intelligent block propagation with optimistic processing.

Q: Can Sei handle NFT minting?
A: Yes, but minting is serialized to ensure uniqueness, while other transactions run in parallel.

Q: Why choose Sei over Ethereum for DeFi?
A: Lower fees, faster transactions, and built-in scalability solutions.

Q: Is Sei’s oracle system reliable?
A: Prices are validated per-block by consensus among validators.
