Blockchain Layer 1 vs. Layer 2. A detailed comparison

There was always a critical eye in the industry when cryptocurrencies were introduced to the mainstream. It looked deep enough to see the benefits and drawbacks of this unconventional technological solution. The Blockchain Technology was the central pillar of any crypto network and has been the topic of much discussion among bright minds.


Experts were able to discover the limitations and potential of blockchain technology as an asset. While high-end security, transparency and immutability were the benefits, concerns about its widespread proliferation raised concern. As blockchain usage continues to increase, scaling is more important. The system throughput rate of the blockchain networks can be improved to support new applications and more transactions. Industry users often pay attention to the question of layer 1 and layer 2 when discussing blockchain scalability.

Tech experts created multiple layers of blockchain to encourage widespread adoption of cryptocurrency. Blockchain development facilitated network security and improved the record-keeping process for users. A third-party solution can be added to layer 1 to increase scaling functionality. Although the different layers may be technical aspects of a blockchain ecosystem they can help you better understand the DLT channel. Let’s dive deeper into Layer 1 & Layer 2 blockchain infrastructures to learn more about their features, characteristics, and critical resources that are different from one another.

Why is Scalability Important?

Blockchain technology offers many benefits, including improved security, record-keeping, frictionless transactions, and better security. Industry experts still have to address the issue of scaling, but blockchain technology has made great strides in many industries. DLT is a decentralized infrastructure that streamlines transaction chains and payment networks. A blockchain channel’s ability to handle increasing transactions and the increased number of nodes in the network is what determines its scalability.

Multiple processes are involved in a typical blockchain process. They take place sequentially and systematically. These transactions require significant computing power, energy, as well as rigorous mathematical calculations by miners. Although a blockchain network can simultaneously handle multiple transactions, it still falls short of traditional payment channels. The blockchain is unable to function efficiently as the transaction load increases. To manage this growing load, scaling up is essential as it will help to determine the future of the blockchain ecosystems.

What Causes Scalability Problems in Blockchain Networks

It is essential to identify the root cause of the problem before you can determine the difference between layer 1 or layer 2 scaling solutions. This is why we have to address it.

The execution time and processing power of a blockchain transaction have a large impact on its authenticity and integrity. To be successful, the transactions must be accepted, mined and distributed on a node network. Blockchain Development networks can’t keep up with the growing demand for security and decentralization. Tech experts create a Blockchain with multiple levels.

Layer 1 & Layer 2 Solutions

Many Layer 1 solutions are focused on increasing the network’s ability to quickly manage large volumes of transactions and not getting bogged down. Layer 2 solutions, however, focus on integrating the mainnet and third-party blockchain networks. Layer 2 solutions are, however, more focused than layer 1. They support the base protocol using off-chain solutions and protocols.

Layer 1 and Layer 2 are distinct in many aspects. It is important to fully understand both the layers and the differences between them. It may be easier to compare scaling solutions for layer 1 or layer 2 of the Blockchain if you are able to grasp them in depth through Blockchain technology classes.

About Blockchain Layer 1

As its name implies, Layer 1 blockchain network is about the core protocol of the blockchain. It refers to a base network such as Bitcoin, BNB Chain, or Ethereum, along with their decentralized infrastructures. Layer 1 solutions are able to verify, validate and complete trades without any dependency on other networks. These protocols use their own crypto coins to pay transaction fees. Layer 1 scaling solutions aim to improve the infrastructure foundation of the blockchain protocol to increase its scalability.

Layer 1 solutions can help you learn about many ways to improve the scalability and efficiency of blockchain networks. Layer 1 solutions may allow you to modify protocol rules directly to increase transaction volume or speed. Layer 1 scaling solutions can accommodate more users and data. These solutions often increase the block size and decrease the time required to create new transactions.
The dispute about layer 1 vs. 2 would consider the two most important layer 1 scaling methods. Only two things can be done to increase layer 1 scaling in blockchain networks: modify the consensus mechanism or implement sharding.

In terms of execution of transactions, some consensus techniques like Proof of stake may be more efficient that Proof of Work blockchain protocols. It helps to distribute the network’s burden across a set number of datasets known as “nodes”, which are also known as shards.

Layer 2 Scaling Solutions

Layer 2 protocols are based on the idea that blockchain has a lot of potential and is undergoing unprecedented development. Layer 2 solutions are secondary frameworks built on top of existing blockchain ecosystems. These solutions are designed to speed up transactions and reduce scaling complications within the sector.

Layer 2 scaling solutions transfer the transaction load from the blockchain protocol onto an off-chain infrastructure. The off-chain architecture would then report the transaction to the main blockchain once it is completed. Layer 2 scaling solutions allow you to easily delegate data processing tasks to infrastructure. Because there is no congestion in core blockchain technology, this allows for greater scaling.
The Lightning Network is an example of layer 2 scaling, and is used to scale Bitcoin. Lightning Network can speed up and simplify Bitcoin blockchain transactions. There are many ways to help layer 2 scalabilities, in the dispute between layer 1, and layer 2, blockchains. Layer 2 scaling solutions include sidechains and nested blockchains.

The difference between Layer 1 and Layer 2 of the Blockchain

You can distinguish layer 1 and 2 scaling options based on their basic outline. These are some of the notable differences between layer 1 blockchain scaling options and layer 2.


Layer 1 scaling solutions refers to any changes made to the foundation layer of the blockchain protocol to gain desired benefits. To accommodate more transactions, the block size can be increased or the consensus mechanism may be modified to improve performance.

The weight of layer 2 scaling methods that are not on-chain share the same weight as the primary blockchain protocol. This is the opposite side of the argument “Is Layer-1 better than Layer-2?” A layer 2 application or network receives and processes transactions for the mainnet of the blockchain protocol. Off-chain solutions and protocols are responsible for fulfilling the work assigned and reporting back to the primary Blockchain.

Method of Working

Comparisons of layer 1 and 2 blockchains would also include the fundamental strategy or functioning technique. The primary mechanism to scale layer 1 blockchain networks is through changes to the protocol. Blockchain systems must be modified to scale layer 1. If transaction volume drops dramatically, it’s impossible to reduce the number of adjustments quickly.

Layer 2 scaling solutions are off-chain solutions which do not depend on the primary protocol. They provide only the final findings that are required by the primary protocol in off-chain protocols or networks. Layer 2 blockchain scaling solutions distributes the transaction load across multiple blockchains.

Different Implementation Approaches

In terms of the solutions that users can derive from layer 1 and layer 2, blockchains are different. This is the second most important criterion to answer our core question. There are two important types of layer 1 blockchain solutions that can be found: Consensus protocol enhancement, and sharding. Layer 1 scaling also allows for modifications to block size and creation speed to ensure the required functions. Blockchain Engineer with deep knowledge of blockchain layers and infrastructure can manage these crucial processes.

There are many options when it comes to scaling solutions at blockchain layer 2. Any protocol, network, and application can provide off-chain layer 2 solutions to blockchain networks. It is important to consider layer 2 scaling solutions, such as state channels and sidechains and nested chains.


Because they have the only access to the source truth, layer 1 networks are the ultimate arbiters for transaction outcomes. You will find a native token on layer 1 networks that allows you access to the network’s resources. Innovation in consensus process design is an important characteristic of layer 1 blockchain networks.

Layer 2 networks and scaling solutions can be added to provide the same functionality that layer 1 blockchains, but with certain additional characteristics. Layer 2 solutions can, for instance, increase network speed and programmability, while also lowering transaction costs. Layer 2 solutions. Each layer 2 solution takes a different approach to translating transactions back to the base layer.

Limitations for Layers 1 and 2.

There are many benefits to blockchain stacking. Layer 1 solutions are a great option because developers don’t have to modify the existing architecture.

Layer 2 scaling methods on the other side do not interfere with base layer protocol. These methods allow users to make microtransactions, without the need to pay high transaction fees or wait for miner verification. These blockchain layers have limitations that must be considered when using them.

Protocols are being added to the existing ones.

Integrating blockchain layers into existing protocols is the most difficult part of implementing them. Both Bitcoin and Ethereum are valued in the billions. Each day, millions of dollars in goods and services are traded by users. It is therefore not necessary to add complexity to the process by coding or experimenting. This would lead to significant money being spent.

The Scalability Dilemma

Blockchain balances three inherent properties

  • Security
  • Scalability
  • Decentralization

According to some experts, a blockchain system cannot have all three qualities simultaneously. The existing blockchain technology will have to trade off one of its key characteristics. This concept is best illustrated by Bitcoin. Although its blockchain has been effective in optimizing security and decentralization, it has also had to make compromises in terms of scalability. This is completely due to its own fault.

Are there significant differences in the cost of the first and second levels of blockchains?

Although Ethereum Layer 1 blockchain mining and transfer costs fluctuate daily, they are usually between $50 and $125 (USD). Polygon Layer 2 transactions are approximately $0.05. This is a factor of roughly 2,000 times lower than their Layer 1 counterparts. Because Layer 2 blockchains have more efficient architectures, they are less expensive than Layer 1.

What’s the Future for Layer 1 and 2?

The inability of the blockchain industry to gain widespread acceptance is due to its inability to scale. The demand for cryptocurrency continues to grow, so the need to scale Blockchain platforms will increase. The future solution to the scalability dilemma will be to create a protocol that can bypass the restrictions at both blockchain levels.


Both layers of the blockchain have a common goal: increasing scalability. The Layer 1 layer of the original blockchain technology has been modified to be more scalable. Layer 2 scaling is used to increase the blockchain’s scalability. It uses third-party protocols, networks or technologies. Support for off-chain solutions, which share the burden of the blockchain network’s scaling is easier.

When you take a close look at both of them, it becomes clear that each represents a significant step in the evolution and development of the blockchain protocol. DeFi and NFTs are attracting more people to the blockchain ecosystem. Scalability is crucial for the long-term viability and sustainability of blockchains. To navigate the sector’s dynamic, learn more about blockchain technology and its implications. Investors looking for quick rewards can take advantage of the industry’s growth by taking advantage of unprecedented opportunities.
