Ethereum
About
What Is Ethereum (ETH)? Ethereum is a decentralized smart contract blockchain launched in 2015 that allows developers to build decentralized applications (dApps), DeFi platforms, NFTs, and DAOs. It runs on a proof-of-stake (PoS) consensus mechanism and serves as the foundation of the Web3 ecosystem.
How It Works
A global programmable blockchain for smart contracts that uses Proof of Stake (PoS). It enables developers to build decentralized applications (dApps) and financial systems. Validators stake their own tokens to verify transactions instead of relying on energy-intensive mining.
Use Cases
Decentralized Computing: Used as “gas” to pay for smart contract execution, power decentralized applications (dApps), and mint/trade NFTs on the world’s most active developer network.
Tokenomics
Deflationary Infrastructure: Used to pay “gas” for smart contract execution. Its tokenomics include a fee-burn mechanism (EIP-1559) that destroys a portion of fees, which can make ETH net deflationary during high network usage. It’s a primary form of collateral in DeFi and a base currency for many NFT markets.
Risks & Considerations
A structural shift toward Layer 2s may dilute base-layer fee burns; institutional ETF demand creates heavy macro dependency.
Sei
About
What Is Sei (SEI)? Sei is a high-performance Layer 1 blockchain optimized for trading and decentralized finance applications.
How It Works
A Layer 1 blockchain optimized for high-frequency trading. It includes a built-in central limit order book and is designed to reduce front-running while maintaining decentralization.
Use Cases
Trading Specificity: Used as the gas token on a blockchain with a built-in order-matching engine designed for DEXs and professional traders.
Tokenomics
Trading-Centric L1: Includes an on-chain order-matching engine. The token is used for gas and staking, targeting pro-grade trading performance on a decentralized network.
Risks & Considerations
Very high volatility in 2026; ecosystem growth is offset by aggressive validator emissions.
