⚡ Sei Network: an ultra-fast or too fragile blockchain to hold?

Sei Network: an ultra-fast or too fragile blockchain? #SeinetWork #BlockChain #Cosmos #Defi #Trading #Crypto2025 #Layer1 #Financenumeric #Mev #ThroughPut 👋 Hello everyone! Today, we are tackling a Layer 1 that has been a lot of talk about him since his launch: Sei Network, a blockchain specializing in high frequency decentralized trading, which promises to reach new speeds in the web3 universe. Positioned as the "Solara of Trading", SEI boasts of extreme performance: subsecond finality, 20,000+ transactions per second, optimized ordering transaction, MEV management, etc. But are these promises tenable over time? And above all, does this speed not sacrifice resilience and decentralization? In this script, we will see together: ✅ What Sei Network is and its technical specificities. ✅ Why is it cut for trading and limit dapps. ✅ Concrete innovations: Native Matching Engine, Parallelization transaction. ✅ Critics around stability, centralization, token sei. ✅ And if SEI can really become the infrastructure platform for decentralized trading. [Chapter 1 - Sei Network: a blockchain for the Exchanges] 🔹 1. A clear vision: becoming the infrastructure layer for the limit orders ✅ SEI is not a general blockchain like Ethereum or Cosmos Hub. ✅ It focuses on a specific but massive niche: trading. ✅ Objective: host Dexs, Order Books, Perp Platforms, Options, Oracles, with sufficient performance to compete with the CEX. 📌 "Binance speed, transparency of the web3." 🔹 2. Optimized architecture Cosmos SDK ✅ SEI rests on Cosmos SDK and Tendermint, but with many low level customations to accelerate the consensus and the propagation of the blocks. ✅ It uses Twin-Turbo Consensus, an improved Cometbft fork, with rapid and high speed purposes. 📌 A cosmos blockchain… under steroids. 🔹 3. Instant transactional purpose ✅ The finality is reached in ~ 300 ms, which allows SEI to execute high frequency strategies, such as Market-Making or Arbitrations. 📌 A playground for professional traders. [CHAPTER 2 - Technical innovations that make the difference] 🔹 1. Matching Engine natively integrated ✅ Unlike other L1 which let the Dex Manage their own Order Books, SEI offers a native matching engine at the level of the protocol. ✅ This guarantees coherence, speed, and absence of front-drinning. 📌 The order is deterministic, not manipulable. 🔹 2. Parallelization transaction ✅ SEI can execute several transactions in parallel, identifying potential conflicts in advance. ✅ This maximizes the throughput without sacrificing consistency. 📌 A VM suitable for intensive trading. 🔹 3. Integrated anti-MEV ✅ thanks to an optimized ordering transaction logic, SEI strongly limits the opportunities of MEV (sandwich, forced arbitration, etc.). ✅ Traders are on an equal footing. 📌 More transparency = more confidence. [Chapter 3 - Case of use targeted by SEI] 🔹 1. Dexs sur order Book ✅ SEI is ideal for projects like Dexterity, Vortex, and Sushix who wish to deploy platforms with native order book. ✅ This allows a UX close to Binance, but decentralized. 📌 LPS can place limit orders. 🔹 2. Perp trading and derivatives ✅ Thanks to its speed, SEI can host derivative platforms with rapid liquidation, low briefing, low latency. 📌 An environment “Cex-Level” but not custom. 🔹 3. High frequency oracles ✅ Quick execution makes it possible to refresh oracles more often, therefore to secure protocols sensitive to prices. 📌 Less LAG, fewer handling attacks. 🔹 4. Gaming and Defi Sync ✅ Sei also attracts gaming projects that need rapid actions resolution, while remaining on-chain. 📌 Gameplay in real time, possible thanks to performance. [Chapter 4 - The token SEI and the ecosystem] 🔹 1. The token SEI ✅ SEI is used to: pay the Staker transaction costs to secure the Participation network in Governance 📌 A classic L1 utility token, but in a specialized ecosystem. 🔹 2. Inflation and distribution ✅ The tokenomics of SEI was criticized for a large part reserved for Early investors, with massive unlocks to come. ✅ This caused a sales pressure when launching. 📌 A fragile economy so badly controlled.
