16 June 2022
Let’s bePAY helps you to research what is layer 2 crypto and the layer 2 cryptosphere blockchain. If you are familiar with blockchain scalability, you are also familiar with layer 2 cryptosphere blockchain. The expansion and adoption of blockchain networks are reliant on their scalability. The demand for layer 1 blockchain solutions would arise at this point. That’s where layer-2 comes in to help.
What are layer two blockchain crypto solutions? What differentiates them from blockchain-based layer 1 solutions? In this post, we will examine the principles of blockchain layer 2 in greater detail. A comprehensive comparison of criteria in crypto layer 1 vs. layer 2 blockchain and a search for the best layer 2 crypto coins in amongst layer 2 crypto list.
What Is Layer 2 Blockchain?
The second framework or protocol constructed on top of an existing blockchain system is referred to as Layer 2 (Layer-2 or L2). The fundamental purpose of these protocols is to tackle the transaction speed and scaling challenges that are being faced by the major cryptocurrency networks.
In the case of Bitcoin and Ethereum, their inability to perform thousands of transactions per second (TPS) is detrimental to their long-term growth. Before these networks can be efficiently embraced and utilized on a larger scale, there is a requirement for increased throughput.
In this sense, “layer 2” refers to the several proposed solutions to the blockchain scalability issue. Bitcoin’s Lightning Network and Ethereum’s Plasma are two notable instances of layer 2 solutions. Despite having distinct operating principles and characteristics, both technologies aim to boost blockchain systems’ throughput.
What is layer 2 blockchain?
The Lightning Network is specifically based on state channels, which are essentially attached channels that perform blockchain activities and report them to the main chain. State channels are predominantly used for payments. In contrast, the Plasma architecture consists of sidechains, which are effectively tree-like arrangements of mini blockchains.
In a larger sense, layer 2 protocols establish a supplementary framework in which blockchain transactions and operations can occur independently of layer 1 (Layer-1, or L1) protocols (main chain). Consequently, these strategies are sometimes known as “off-chain” scaling solutions.
As the second layer is added as an extra layer, the main chain does not need to undergo any structural changes. This is one of the primary advantages of off-chain solutions. Consequently, layer 2 solutions can achieve high throughput without compromising network security.
In other words, a substantial amount of the work that would be performed by the main chain can be shifted to the second layer. Consequently, although the primary chain (layer 1) provides security, the second layer enables high throughput, with the capacity to process hundreds or thousands of transactions per second.
What Are The Differences Criterias Of Layer 1 Vs Layer 2 Cryptosphere?
Layer 1 Scaling Solution
A Layer 1 network is a blockchain in the decentralized ecosystem, whereas a Layer 2 protocol is a third addition that might be utilized in conjunction with a Layer 1 blockchain. Included in Layer 1 blockchains are Bitcoin, Litecoin, and Ethereum. Layer 1 scaling solutions augment the blockchain protocol’s foundation layer to increase scalability. Numerous techniques are continually being developed and applied to improve the scalability of blockchain networks.
Layer 1 vs layer 2 cryptosphere
Here is how it operates: Layer-1 solutions directly modify the protocol’s rules to boost transaction capacity and speed, as well as to accommodate additional users and data. In order to increase network throughput, Layer-1 scaling options may involve increasing the quantity of data in each block or the pace at which blocks are verified.
Layer 2 Scaling Solution
Layer 2 blockchains utilize the native layer to boost efficiency. Layer 2 effectively offloads transactions by shifting a portion of the transactional weight of Level 1 blockchain to another system design.
The processing burden is subsequently managed by the Layer 2 blockchain, which notifies Layer 1 of the finalized results. Because this neighboring auxiliary architecture handles the majority of the data processing burden, network congestion is decreased; the Layer one blockchain is also more scalable.
Bitcoin is an example of a Layer one blockchain, whereas the Lightning Network is a Layer 2 scaling solution that simultaneously takes Bitcoin’s load and reports it to it. As a result, the Lighting Network accelerates the processing of the Bitcoin blockchain.
In addition, the Lightning Network incorporates smart contracts into the Bitcoin Layer 1 network.

Benefits Of Layer 2
Layer 2 scalability solutions are essential because they provide scaling and higher throughput while preserving the Ethereum blockchain’s integrity, hence delivering total decentralization, transparency, and security while reducing carbon emissions.
Despite the fact that Ethereum is the most popular and possibly most secure blockchain, it is not without flaws. The Ethereum Mainnet is well-known for its long transaction times (13 per second) and high gas fees. Since they are constructed on top of the Ethereum blockchain, Layer 2 transactions are secure, fast, and scalable.
Each system has its own advantages and disadvantages, including throughput, gas costs, security, scalability, and performance, among others. No layer 2 solution currently meets all of these requirements. Rollups, however, are layer 2 scaling algorithms that aim to increase all of these properties.
The advantages of layer 2
Limitations Of L1 And L2
Blockchain stacking has numerous advantages. The key benefit of Layer 1 solutions, for instance, is that developers do not need to add anything to the existing architecture because the base layer is modified.
Meanwhile, Layer 2 scaling solutions do not modify the protocol at the base layer. In addition, these systems permit many microtransactions without requiring consumers to pay exorbitant transaction fees or spend time on miner verification. Nonetheless, both of these blockchain levels have restrictions that must be considered.
Improvement Of Current Protocols
Adding blockchain layers to existing protocols is the primary difficulty associated with them. Bitcoin and Ethereum both have billion-dollar market capitalizations. Users exchange billions of dollars per day. Since this would cost a great deal of money, it makes little sense to complicate the process with unnecessary code and experimentation.

The Blockchain Trilemma
Vitalik Buterin, the founder of Ethereum, coined the phrase “scalability trilemma” to describe the ability of a blockchain to balance three organic properties:
- Security
- Scalability
- Decentralization
The trilemma asserts that blockchain technology can only possess two of the three traits, never all three simultaneously. Consequently, the existing blockchain technology will always be required to sacrifice one of its core qualities. Bitcoin is a prime illustration of this. While its blockchain has optimized decentralization and security, scalability has been compromised – through no fault of its own.
