What is Layer 3 in Blockchain?

What is Layer 3 in Blockchain? – It’s the key protocol for blockchain-based solutions. Commonly known as the “application layer,” it gives instructions to Layer 1 protocols for processing. This allows dapps, games, distributed storage, and other applications on a blockchain platform to work correctly.

Without these applications, Layer 1 protocols would have limited usefulness. It’s crucial for unleashing their potential.

Layer 3 Blockchain Scaling Solutions

Layer3 blockchain scaling solutions strive to elevate blockchain technology by providing improved scalability, interoperability, and cost-effectiveness. These solutions build on the groundwork established by Layer 1 and Layer 2 solutions, enabling blockchain networks to better meet future requirements.

  • Definition: Hosts decentralized applications (DApps) and executes specific functions.
  • Role: Hosts real-world applications and executes tasks.
  • Functionality: Executes tasks specific to applications.
  • Purpose: Hosting applications and specialized functions.
  • Interactions: Interaction with applications and Layer 2.
  • Examples: Polkadot, Cosmos, Chainlink

Layer 3 Network

Layer3 Blockchain networks were developed to create a safer, more adaptable, and expandable blockchain system. Although both Layer 2 and Layer3 solutions aim to enhance the scalability of the blockchain network, Layer3 focuses on linking different blockchains and enabling smooth communication between them.

Layer3 networks function on Layer 2 solutions, connecting numerous Layer 2 networks and enabling transactions across diverse blockchains, which conventional Layer 2 solutions cannot accomplish.


Layer3 protocols enable users to access applications on the entire system, ensuring a secure and efficient infrastructure for handling large-scale transactions.
