Introduction: The Backbone of Decentralized Ecosystems
Layer 1 blockchains form the foundational infrastructure of decentralized networks, enabling trustless transactions, smart contracts, and consensus mechanisms. Unlike Layer 2 solutions that build atop existing chains, Layer 1 protocols like Ethereum and Solana govern core operations—validating transactions, securing networks, and maintaining decentralization. Their business models balance technological innovation with sustainable monetization, addressing critical challenges like scalability and security while fostering developer ecosystems.

What Is a Layer 1 Blockchain?
Layer 1 business models are structured to balance technological innovation and sustainable monetization, solving challenges such as scalability and security while nurturing developer ecosystems. These models are designed to optimize revenue streams within the Layer 1 networks, targeting specific customer segments. Some of the leading Layer 1 projects, like Bitcoin and Ethereum, exemplify these strategies through their focus on security, decentralization, and consensus mechanisms.
Defining the Core Infrastructure
Layer 1 refers to the base protocol of a blockchain, encompassing its consensus algorithm, transaction validation rules, and native tokenomics. These networks operate independently, processing transactions without relying on external systems. Bitcoin’s Proof of Work (PoW) and Ethereum’s transition to Proof of Stake (PoS) exemplify Layer 1 architectures that prioritize security and decentralization.
Layer 1 Business Models
Key Problems Layer 1 Solves
- Decentralization vs. Scalability: Layer 1s tackle the “blockchain trilemma” by optimizing trade-offs between speed, security, and decentralization.
- Trustless Transactions: Eliminating intermediaries through cryptographic verification.
- Smart Contract Execution: Enabling programmable agreements for DeFi, NFTs, and dApps.
Revenue Streams in Layer 1 Networks
- Transaction Fees: Users pay gas fees (e.g., Ethereum’s ETH) to execute transactions or deploy smart contracts.
- Token Issuance: Native tokens (e.g., SOL, ADA) fund network operations and incentivize validators.
- Staking Rewards: Participants earn yields by locking tokens to secure the network.
- Developer Grants: Allocating tokens to attract builders, as seen with Ethereum’s Ecosystem Support Program.

Target Customer Segments
- Developers: Building dApps and protocols atop the blockchain.
- Enterprises: Leveraging Layer 1 for supply chain transparency or financial solutions.
- Retail Users: Engaging with DeFi, NFTs, or cross-border payments.
Leading Layer 1 Projects and Their Strategies
Ethereum: The DeFi Pioneer
Ethereum monetizes through ETH gas fees and staking rewards. Despite post-Dencun upgrade revenue declines, its ecosystem thrives via L2 rollups and developer incentives.
Solana: Speed at Scale
Solana’s hybrid Proof of History (PoH) consensus enables 65,000 TPS, attracting high-frequency trading dApps. Revenue flows from SOL transaction fees and validator rewards, as the recent meme-coins mania is showing.
Avalanche: Subnet Flexibility
Avalanche’s subnet architecture lets enterprises create custom blockchains, monetizing through AVAX fees. Its “Elastic Supply” model adjusts token issuance based on demand, balancing inflation and staker returns.
BNB Chain: Centralized Efficiency
BNB Chain combines low fees with Binance’s centralized exchange liquidity. Revenue stems from BNB token burns and DeFi integrations, though critics cite trade-offs in decentralization.
Challenges and Future Innovations
Scalability Limitations
Ethereum’s sharding delays and Solana’s network outages underscore the difficulty of maintaining performance under load. Layer 1s increasingly adopt modular designs (e.g., Celestia’s data availability layers) to offload tasks to specialized chains.
Regulatory Risks
SEC scrutiny of tokens like SOL and ADA as securities threatens staking models. Projects must navigate compliance while preserving decentralization.
The Rise of AI Integration
Casper Labs’ Prove AI illustrates how Layer 1s can audit AI systems, merging blockchain’s immutability with machine learning transparency.
Conclusion: The Evolving Layer 1 Landscape
Layer 1 blockchains remain pivotal to Web3’s growth, balancing innovation with economic sustainability. As Ethereum adapts to post-Dencun realities and newcomers like Sei achieve 20,000 TPS, the race to solve scalability and monetization will define the next decade of decentralized tech.
