What are Level 1 Altcoins?

Level 1 (L1) altcoins are cryptocurrencies that run on their own independent blockchain networks. Unlike tokens that depend on other blockchains (like ERC-20 tokens on Ethereum), L1 altcoins power their own ecosystems, enabling smart contracts, DeFi apps, NFTs, and more. In simple terms, Bitcoin and Ethereum are Level 1 blockchains. Similarly, Solana, Avalanche, and Cardano are popular L1 altcoins that are trying to improve speed, cost, and scalability compared to older blockchains.



How Do Level 1 Altcoins Work?

Level 1 altcoins provide the base infrastructure for developers to build decentralized applications (dApps). These blockchains have their own native coins used for transactions, staking, and governance.

Key Features:

  • Independent blockchain

  • Supports smart contracts

  • Native coin (e.g., SOL, AVAX, ADA)

  • Often scalable and cheaper than Ethereum

Top Level 1 Altcoins to Know in 2025

1. Ethereum (ETH) – The Original Smart Contract Platform

Ethereum is the most established L1 altcoin. It's used for everything from DeFi to NFT marketplaces. Although gas fees are high, the upcoming Ethereum upgrades (Danksharding and Proto-Danksharding) aim to reduce costs and increase scalability.
Benefits of Ethereum:

  • Massive developer community

  • Thousands of dApps

  • Strong institutional adoption

  • Ethereum 2.0 upgrade is ongoing

2. Solana (SOL) – High-Speed Blockchain



Solana is known for very fast transaction speeds (65,000+ TPS) and low fees. It's popular among gaming and NFT developers. Even though it faced downtime issues in the past, it’s rapidly improving.
Benefits of Solana:

  • Fast and cheap transactions

  • Growing NFT ecosystem

  • Backed by major VCs

  • Suitable for real-time apps like gaming

3. Avalanche (AVAX) – Ethereum Compatible Chain

Avalanche offers high scalability and has three interoperable blockchains (X-Chain, P-Chain, and C-Chain). It's also EVM-compatible, which means Ethereum-based apps can run on Avalanche with minor tweaks.
Benefits of Avalanche:

  • High throughput

  • Low latency

  • Eco-friendly consensus (Snowman Protocol)

  • Ethereum-compatible

4. Cardano (ADA) – Academic and Peer-Reviewed Blockchain

Cardano focuses on security, research, and long-term stability. It uses a proof-of-stake consensus model and is popular in regions like Africa for real-world use cases like digital identity and education.
Benefits of Cardano:

  • Energy-efficient

  • Formal academic research

  • Large and loyal community

  • Real-world government partnerships

Why Are Level 1 Altcoins Important?

L1 altcoins are the foundation of blockchain ecosystems. Without them, platforms like DeFi, NFTs, and Web3 apps wouldn’t function.

Advantages of Investing in Level 1 Coins:

  • Early exposure to next-gen blockchain tech

  • Potential high returns as adoption grows

  • Ecosystem growth leads to coin demand

  • Often less risky than meme or L2 tokens

Real-Life Use Case Examples

  • Ethereum: Used in Uniswap, OpenSea, and Aave

  • Solana: Powers the StepN fitness app

  • Avalanche: Used in DeFi platforms like Trader Joe

  • Cardano: Partnered with Ethiopia for a blockchain-based education system





FAQs

Q1: Are Level 1 altcoins better than Bitcoin?

Not necessarily better, but they serve a different purpose. Bitcoin is a store of value, while L1 altcoins enable smart contracts and applications.

Q2: Can I stake Level 1 altcoins?

Yes! Most L1 altcoins use proof-of-stake mechanisms where you can earn rewards by staking coins.

Q3: Which Level 1 coin is the fastest?

Solana is currently one of the fastest L1 blockchains with over 65,000 TPS.

Q4: Are L1 coins safe to invest in?

They are generally safer than meme coins but still carry market risk. Always DYOR (Do Your Own Research).

Conclusion

Level 1 altcoins are the backbone of modern blockchain infrastructure. Coins like Ethereum, Solana, Avalanche, and Cardano offer real utility and long-term growth potential. If you're exploring crypto in 2025, understanding and investing in L1 coins could be a smart move.
