**Ethereum (ETH)
Ethereum is the #1 smart contract blockchain, powering DeFi, NFTs, and dApps. Its native token, ETH, fuels transactions and staking. Key features:
- **Proof-of-Stake**: Energy-efficient since the Merge (2022).
- **Layer 2 Scaling**: Rollups (Arbitrum, Optimism) cut fees.
- **Upcoming Upgrades**: Proto-danksharding (EIP-4844) aims for cheaper L2s.
- **ETF Potential**: SEC approval could boost institutional demand.
- **Staking Rewards**: ~4% APR, with ~30% of ETH supply locked.
Challenges include high gas fees during congestion and rivals like Solana. However, Ethereum’s developer dominance and roadmap keep it ahead. ETH remains a blue-chip crypto bet. 💎🔷
