What Is a Layer 1 Blockchain?
A Layer 1 blockchain, or smart contract platform, serves as the foundational layer for crypto ecosystems. Examples like Ethereum host Layer 2 projects (NFTs, DeFi, Web3) while ensuring network security and settlement functions.
Key Differences Between Layer-1 Blockchains
Smart contract platforms compete on three fronts:
- Scalability: Transaction speed/capacity.
- Security: Resistance to attacks.
- Decentralization: Node distribution.
The blockchain trilemma highlights the challenge of excelling in all three. For instance:
- Ethereum: Secure/decentralized but struggles with scalability.
- Binance Coin: Scalable/secure but less decentralized.

Market Shifts: Ethereum vs. Competitors
Ethereum’s scaling issues (high fees, ~62% TVL share drop in 2021) fueled growth for alternatives:
| Blockchain | TVL (2021) | Annual Growth |
|---|---|---|
| Ethereum | AU$214B | ~600% |
| Terra | AU$25B | ~22,000% |
| Solana | AU$15B | ~16,310% |
Why the shift? Demand for low-cost, high-throughput transactions drove users to alternatives like Solana and Avalanche.

FAQ
Q1: Which Layer 1 is most decentralized?
A: Ethereum.
Q2: Why choose Avalanche over Ethereum?
A: Faster transactions, lower fees.
Q3: Is Solana’s downtime a concern?
A: Yes, but its speed compensates for occasional outages.
Future Outlook: Layer 2 vs. Ethereum Killers
Ethereum’s Layer 2 solutions (e.g., rollups) aim to reclaim market share, while competitors push scalability. Diversifying across platforms may hedge risks.
