Layer 2 vs Layer 1: The Ultimate Choice for Blockchain Development


In the transformative world of blockchain development, developers must choose between Layer 1 and Layer 2 solutions. Each has its own set of advantages and use cases that cater to different needs. 

In this blog, we will look at the differences, use cases, and factors to think about when deciding between Layer 1 and Layer 2 solutions for your blockchain project. And, in what case layer 1 and 2 is needed.

Layer 1 vs Layer 2 Solutions

Layer 1 SolutionsLayer 2 Solutions
Layer 1 serves as the foundational or main layer of a blockchain network. It  encompasses famous blockchains like Ethereum, BSC, and Polkadot. In addition, these platforms are renowned for their security, decentralization, and consensus mechanisms. These features make them an ideal choice for launching new blockchains.Layer 2 is developed to enhance the scalability and efficiency of Layer 1 blockchains. In addition, it encompasses various technologies including side chains, state channels, and roll ups, each offering unique approaches to address scalability issues.

When to Choose Layer 1 Solution

Objective 1: 

  • Select Layer 1 solutions when the objective is to launch a completely new blockchain with independent rules and regulations. Although, it is well-suited for projects that necessitate full control over their blockchain parameters, such as setting transaction fees, block times, and consensus mechanisms.

Objective 2: 

  • Layer 1 solutions are the go-to option for applications prioritizing maximum decentralization, security, and resistance to censorship. The immutability and security of the base layer make it an ideal choice for mission-critical projects.

When to Choose Layer 2 Solution

Objective 1: 

  • One should go for Layer 2 solutions when the project’s primary concern is scalability and cost-effectiveness. Additionally, these solutions excel in handling high transaction volumes while keeping fees low. Thus, applications like microtransactions, gaming platforms, and NFT marketplaces particularly benefit from Layer 2’s efficiency.

Objective 2: 

  • If your project involves multiple blockchain ecosystems or if you require seamless interaction between different Layer 1 networks, Layer 2 provides the versatility needed to bridge these worlds effectively.

Benefits and Drawbacks

Speed and ScalabilityLimited scalabilityEnhanced scalability and speed
Development TimeTime-consuming to launch a new chainFaster development and deployment
Cost EfficiencyHigher transaction feesLower transaction costs
Use CasesComplex applications, DeFi, DAppsScalable DApps, gaming, NFTs

Combining Layer 1 and Layer 2

There are situations, when a client ask for both Layer 1 and Layer 2, combining these two create hybrid solutions;

Hybrid Solutions

Some projects benefit from a combination of Layer 1 and Layer 2 solutions, strategically leveraging the strengths of both to achieve specific project objectives. This approach is effective in striking a balance between security and scalability.

Cross-Chain Functionality

Consider solutions that offer cross-chain compatibility, allowing seamless interaction between different Layer 1 and Layer 2 blockchains. This interoperability can unlock a world of possibilities for your project.

Community and Ecosystem

  • Explore the existing developer community and resources available for Layer 1 and Layer 2 solutions. 
  • A robust ecosystem can significantly impact your project’s success.


  • Calculate the expenses associated with transactions, network maintenance, and development. 
  • A clear understanding of costs helps you make an informed choice.

Who needs these Blockchain solutions? 

There are two scenarios, and in both, a comprehensive understanding of the client’s goals and technical requirements is important in order to deliver a tailored solution that meets their needs effectively. BloxBytes, as a Web3 and blockchain development company, excels in providing expert guidance and development services for a wide range of blockchain solutions, from Layer 1 to Layer 2.

Scenario 1: Developing a Layer 2 Solution

Client’s Issue: The client wants to enhance the scalability and transaction throughout their existing Layer 1 blockchain, which is struggling with congestion and high fees.

Solution: Layer 2 Development

  • Begin by thoroughly understanding the client’s existing Layer 1 blockchain, its consensus mechanism, and the specific issues they’re facing with congestion and high transaction fees.
  • Identify the use cases and smart contracts that need to be offloaded to Layer 2 to alleviate the pressure on Layer 1.
  • Evaluate various Layer 2 technologies like sidechains, state channels, and rollups to determine which one aligns best with the client’s requirements.
  • Consider factors such as security, interoperability, and user-friendliness.
  • Collaborate with the client to design the architecture of the Layer 2 solution, including the consensus mechanism and data availability.
  • Develop the Layer 2 infrastructure and smart contracts that will enable off-chain or sidechain interactions.
  • Thoroughly test the Layer 2 solution, simulating various use cases to ensure it can handle the expected transaction volumes efficiently.
  • Conduct security audits to identify and address vulnerabilities.
  • Implement the necessary bridges or protocols to ensure seamless communication and interoperability between Layer 1 and Layer 2.
  • Develop mechanisms for assets to be securely locked on Layer 1 when moved to Layer 2.
  • Deploy the Layer 2 solution and monitor its performance, looking for any issues related to congestion and transaction fees.
  • Set up robust monitoring and alerting systems to detect and address any anomalies.
  • Educate users about the benefits of using Layer 2 for specific use cases and transactions.
  • Provide clear instructions on how to utilize Layer 2 effectively.
  • Continue to support the client by optimizing the Layer 2 solution and making necessary updates.
  • Keep an eye on the evolving blockchain landscape for new Layer 2 advancements that could benefit the client.
