Solutions for the Layer 2

Layer 2 solutions / Blockchain and Smart Contracts News

For blockchains to attain popular use, scaling has been a big hurdle. However, there have been considerable advancements in recent times in the areas of speed and cost, which has been a critical concern as the blockchain grows. Ultra-high speed and decreased charges are now achievable across blockchain systems thanks to second-layer technologies.

Layer 1 and Layer 2: An Overview

Scalability difficulties in blockchain technology are still being researched. The ecosystem is presently undergoing changes, with Ethereum no longer appearing to be the DeFi king and competing blockchains discovering innovative techniques to speed up and lower the cost of transaction processing. We are a blockchain developer with skills and experience in producing high-end tools for solidity developer DeFi and expanding or transferring your existing blockchain at Cryptoauxiliary, a blockchain marketing firm.

What is the purpose of L2?

Scaling blockchains is becoming increasingly important in order to encourage wider use of the technology by private persons and businesses around the world. With continued research, faster blockchain processing capacities will be available soon. This can be accomplished by scaling the various blockchain layers.

The main blockchains currently achieve 3-4 transactions per second, while Ethereum permits 15 transactions per second, making VisaNet's capacity, which can easily handle 1700 transactions per second and process even more during peak times, the perfect throughput in payment capacity.

Scaling Blockchain Layers

There are two types of blockchain layers that are often used. Layer 1 refers to the core blockchain, such as Ethereum, whereas Layer 2 refers to the other technologies or systems that run on top of Ethereum (Layer 1). The following are the characteristics of layer 2 protocols:

Layer 1's security features are sent down to them.

They can handle a higher volume of transactions (throughput)

Transaction fees are lower with them (operating cost)

They approve transactions faster than Layer 1.

In general, Layer 2 scaling solutions are secured by Layer 1, but they allow for more users, data, and processes in blockchain applications than Layer 1.

Scaling the blockchain can be accomplished via scaling the Layer 1 protocol (L1 scaling) or layer 2 solutions built on top of the blockchain (L2 Scaling). Layer 2 scaling is accomplished utilising solutions built on top of the L1 protocol (e.g., Ethereum), which do not necessitate updating the blockchain's basic code. Scaling any of the blockchain layers has various advantages; it has a compounding effect when combined with the other layers. Scaling the layer 1 protocol 10 times and the layer 2 solutions 100 times, for example, will result in a net throughput increase of 1000 times.

There is a distinction to be made between second layer scaling and sidechains that are connected to the main chain. The main benefit of properly implemented L2 technologies is that the core chain is linked to the L2 in such a way that it recognises some of the processes occurring in the solution layer 2 and acts as a check and balance in resolving disputes that may arise from the second layer, such as determining whether funds have been spent or not. Some of them have privacy features that may or may not be desired.

Another important element to consider while creating L2 solutions is data availability. It's important to figure out if the data from L2 transfers is available on the main chain. Some systems, such as Plasma, store data off-chain, which might provide problems if users need to collect it later. ZK-rollups, on the other hand, use a technology that allows data to be stored on-chain and accessed at any moment.

Approaches to Scaling the First Layer

Scaling of the first layer

Despite the fact that the focus of this essay is on layer 2 scaling, let's have a look at how this works in the base protocol. As expected in the case of Ethereum 2, one prominent example is sharding. Adding a counterpart to the blockchain is referred to as sharding. This is intended to increase Ethereum's transaction throughput to 10,000 per second.

Another method for increasing scale is to actively optimise transactions using more efficient signature techniques. BLS signatures are likely to be used in Ethereum 2, while Schnorr signatures are currently in development for bitcoin. The amount of block space occupied by a subset of transactions will be greatly reduced thanks to these signatures.

Finally, increasing the block size limit is required for a direct approach to layer 1 scaling. This can be observed in Bitcoin SV, when a single 370MB block showed 1.3 million transactions after it was mined. This indicates a transaction rate of roughly 2200 transactions per second.

Approaches to layer 2 scaling

Finematics ( ) explains layer 2 scaling.

There have been more advancements in several L2 scaling solutions. There are three primary ways that have been identified:

Because of their validation guarantee and data availability on the main chain core Validum Sidechains, child blockchains, also known as Plasma ZK-rollups, are also known as semi-L2.

Whatever way you pick, our Cryptoauxiliary solidity Defi developers are up to the challenge. We'll assist you with blockchain scaling using the most up-to-date technologies and tried-and-true ways. Let's take a closer look at how these scaling techniques function.

State and payment channels

This is a notion from a previous generation. State channels, also called as payment channels, allow users to move assets and receive information on the blockchain's overall status. Raiden and FinFair'd fate channels for Ethereum, Lightning Network for Bitcoin, and Aeternity, which have built-in protocol with support for blockchain state channels, are all popular examples of projects that use this scaling strategy.

Instead of writing every transaction directly on the chain, the core of channels allows transactions to be exchanged between one other. This method provides huge scalability and transaction throughput that is virtually instantaneous. On the primary blockchain layer, just the results are recorded. When two parties do huge volume transactions with each other in the future, this form of scaling becomes optimal.

Special protection against malicious conduct by either party, on the other hand, must be built into the channel's design. This is due to the fact that any of the channel's participants can withdraw their funds from the channel and return them to the main blockchain.

Despite the fact that channels have been around for a while, popular acceptance has been slow due to the high costs of payment routing and maintaining the channel open when more than two parties are involved.

Blockchains for Children (Plasma)

Creating child blockchains that are linked to the parent chain is another way to achieve L2 scaling. The present Ethereum Blockchain is a good example. Users can readily access the Plasma (Child) chain via a smart contract, and these blockchains frequently write the blueprint of their state to the root chain.

The plasma chain can follow different rules than the main chain, such as a different speed and consensus procedure. It can be adjusted to follow a distinct set of requirements for a payment network or a decentralised app, for example. If a user wants to leave the chain, they'll have to go through a "challenge period" to avoid any fraudulent behaviour.

One of the issues with Plasma chains may be the procedure of departing. In a circumstance where the root chain is congested and there is a mass escape from the child chain, the challenge duration may be insufficient to prevent any harmful action. A lengthier challenge time, on the other hand, causes friction and leads to missed chances due to a lack of fast access to assets or finances.

After years of research, OMG Network (OmiseGo) just launched a classic example of a Plasma chain. It can increase transaction speeds to more than 1000 per second while lowering transaction costs by one-third. Tether, a large gas user on Ethereum, has already been integrated.


Unquestionably, zk-Rollups is the most promising scaling strategy. They employ a transaction batching technique, which uses SNARKs or STARKs to condense multiple transactions (for example, a simple value transfer from column A to B) into a single on-chain transaction. SNARKs (short non-interactive/transparent argument of knowledge) are a cryptographic mechanism used by Zcash to ensure anonymity, but zk-rollups show the scalability benefits they could provide.

Users obtain access to the system through a smart contract, and relayers who receive incentives are in charge of gathering transactions and providing SNARK proofs, which is typically computationally intensive and frequently a bottleneck for the systems.

The initial use case of this system was carried out on the Ethereum mainnet by Loopring, a decentralised trade platform. They improved the proof generating process, lowering the cost per trade to $0.000124.

The main goal of this system was to make operations on the decentralised exchange run smoothly; it also allows for simple ETH or ERC-20 token transfers between users. Loopring Pay has made a tremendous breakthrough by scaling Ethereum transaction capacity by 1000 times with this feature. After the debut, their token, LRC, saw an almost 75 percent increase in value.

How Ethereum's Layer 2 scaling solutions help businesses build on the Mainnet

The majority of Layer 2 solutions are hosted on servers or clusters of computers, which are referred to as nodes, blocks, producers, validators, operators, sequencers, and other words. These L2 nodes could be operated or developed by the businesses or entities that use them, by a third-party validator, or by a big group of users, similar to the Mainnet.

Transactions are typically submitted to these L2 nodes rather than directly to L1; the L2 instance then merges them into groups before securing them to L1; once L1 secures them, they cannot be changed. The implementation approach differs greatly amongst L2 technologies.

Ethereum: Private vs. Public

Many businesses are developing or testing apps on private blockchains. Even while Ethereum Mainnet's open and decentralised nature gives certain advantages, this includes private Enterprise Ethereum technology. They are as follows:

Improved security and immutability

Management that is transparent

Reduced operating costs

Interoperability with other Mainnet applications (network effects)

Instead of building numerous unneeded discrete silos, data can be synchronised by sharing a common frame. L1 secures L2's benefits by providing a common reference, global transaction ordering, and management. Through cross-chain interaction, the L2 enables apps to work together seamlessly.


Second layer scaling is on the right track, and scaling factors of up to 1,000 times are impressive achievements that back up this claim. Because of the lower transaction costs, financial incentives, and the speed with which users can activate network effects, onboarding people to these systems will be a success.

Many L2 solutions will contribute to a thriving and healthy blockchain ecosystem in the future, paving the way for widespread adoption. In general, features such as lower costs, faster speeds, and increased chain usability are in place. The final parts of the puzzle are the extensive integration of various solutions and user-friendly interfaces that do not necessitate a comprehensive understanding of blockchain technology.
