🔺About Avalanche L1
What is an Avalanche L1, and how does it differ from a Subnet?
An Avalanche L1 (Layer-1) is a standalone blockchain within the Avalanche network. It operates with its own rules, validators, and execution layer, designed to meet specific project or industry needs. These blockchains are independent but can communicate with other Avalanche L1s, providing flexibility and scalability.
Avalanche L1s vs. Subnets:
Subnets initially offered customization for blockchains on Avalanche. However, Avalanche L1s represent a more advanced approach, delivering greater control and customization. They enable the creation of specialized blockchains within the Avalanche ecosystem, offering tailored solutions for diverse applications and industries while ensuring interoperability.
Why choose Avalanche for building a custom L1 chain?
Avalanche offers low latency, high throughput, and fast finality. It is ideal for launching high-performance chains with full sovereignty. Avalanche L1s offer a compelling solution for building custom blockchains because they focus on scalability, customization, and performance.
Scalability & Performance: L1s enable horizontal scaling, preventing congestion from other chains and allowing for higher transaction throughput (TPS) and sub-second finality by providing dedicated resources.
Extreme Customization: You gain extensive control over your blockchain, including defining your own gas token, managing validator sets (even permissioned ones for compliance), customizing the EVM, and implementing tailored privacy controls and governance rules. Interoperability & Ecosystem: Avalanche L1s are designed for native interoperability through Avalanche Warp Messaging (AWM), facilitating seamless communication. They also offer Ethereum (EVM) compatibility, making development easier, and benefit from a growing ecosystem in DeFi, GameFi, and enterprise solutions.
Enterprise & Institutional Suitability: The high degree of customization allows for regulatory compliance (e.g., KYC/AML) and provides reliability and security essential for mission-critical applications, often supported by dedicated infrastructure providers. In essence, Avalanche L1s are ideal for projects demanding high performance, specific configurations, isolation from public chain traffic, and a strong ecosystem, making them suitable for various advanced decentralized applications and enterprise solutions.
How does Avalanche’s consensus mechanism work?
Avalanche L1s (including the C-Chain, P-Chain, and custom Subnets) utilize the Snowman Consensus Protocol, a linearized Proof-of-Stake (PoS) mechanism designed for high throughput and fast finality. It also allows for customizable security and compliance for enterprise-grade solutions.
How does an Avalanche L1 compare with Cosmos SDK or rollups?
An Avalanche L1 offers full chain sovereignty and faster deployment compared to Cosmos SDK or Rollups, with lower latency, stronger tooling, and a leaner, more efficient stack. This results in significantly lower infrastructure costs, making it more economical to launch and operate than a comparable Cosmos SDK chain or Rollup.
