Sei
About
Sei is a high-performance Layer 1 blockchain optimized for trading applications, offering fast finality and low latency for decentralized exchanges.
How It Works
A Layer 1 blockchain optimized for high-frequency trading. It features a built-in "Central Limit Order Book" and prevents "front-running," making it feel like a professional stock exchange but with the benefits of decentralization.
Use Cases
Trading Specificity: Used as the gas token for a blockchain built with a built-in order matching engine, designed specifically for decentralized exchanges and pro traders.
Tokenomics
Trading-Centric L1: Uses a built-in "Order Matching Engine" at the chain level. The token is used for gas and staking. It is designed for professional traders who need the speed of a central exchange on a decentralized network.
Risks & Considerations
Very high volatility in 2026; rapid ecosystem growth is offset by aggressive token emissions to validators.
Ethereum
About
Ethereum is a decentralized blockchain platform launched in 2015 that enables smart contracts and decentralized applications without intermediaries, supporting DeFi, NFTs, DAOs and Web3 ecosystems through its proof-of-stake network and large developer community.
How It Works
A global programmable blockchain for smart contracts using Proof of Stake (PoS). It allows developers to build decentralized applications (dApps) and financial systems. Validators stake their own currency to verify transactions instead of using energy-intensive mining.
Use Cases
Decentralized Computing: Used as "gas" to pay for the execution of smart contracts, hosting decentralized applications (dApps), and minting/trading NFTs on the world's most active developer network.
Tokenomics
Deflationary Infrastructure: Used to pay for "gas" to execute smart contracts. Its tokenomics include a burn mechanism (EIP-1559) that destroys a portion of fees, potentially making it deflationary. It is the primary collateral for DeFi and the base currency for the NFT market.
Risks & Considerations
Structural shift toward Layer-2s may dilute base-layer fee burn; institutional ETF demand creates heavy macro-dependency.
