Understanding Layer 2 Solutions: How Ethereum Achieves Better Scalability Through Polygon and Arbitrum

The concept of digital transactions coming through blockchain technology has transformed the world, though scaling is one of the most urgent issues in the field. The weaknesses of transaction processing capacities are becoming more evident as more popular networks such as Ethereum are being used.

The Layer 2 solutions are game changers to understand them better, they provide better performance without compromising the security and decentralization which has made blockchain technology so valuable.

The blockchain ecosystem consists of several layers that have varied purposes in the total framework. The main protocol is Layer 1, which is the base of the overall system on which all transactions are eventually written and confirmed.

The responsibility of this layer is to enforce network security, implement consensus mechanisms, and make sure that the records of transactions are immutable. Nevertheless, this full-fledged duty frequently entails the trade-off of processing speed and scalability.

The solutions are specifically aimed at processing transactions more effectively, with the benefit of utilizing the underlying security infrastructure of Layer 1.

Layer 1 vs Layer 2: Key Distinctions

The main distinctions between the two layers can be seen in the operations:

Layer 1 blockchain:

• •Base operations and whose primary functions are network security and transaction validation
• •Not designed for scalability, tendency to have lower speeds when it comes to transaction execution
• •Causes network congestion and scale issues
• •Transaction fees surge during peak hours and network congestion
• •Has independent consensus and security scheme

Layer 2 blockchain:

• •Operates as a child or secondary blockchain network mostly used to execute transactions
• •Transactions are not handled in the parent network
• •Far greater transaction execution rates because it is specifically designed to accomplish this
• •Still reliant on the parent network to achieve consensus and validation
• •Much higher scalability threshold

These issues are reflected in various crucial spheres, which point to the high urgency of Layer 2 solutions:

Low Throughput

This is a very low throughput compared to the one that is needed by the modern applications and users to work smoothly. This is even further limited when compared to the traditional systems of payment that are able to accommodate thousands of transactions per second.

Processing Delays

This is one of the key limitations particularly when the network is busy and the traffic of transactions is very high. It takes about 15 minutes to add transactions to the blockchain and render them immutable. This is a very long processing time that slows down or causes friction to the users who expect faster confirmation time.

Network Congestion

In cases where high volume of transactions have to be done, speed of the network decreases significantly resulting in slowed down transactions and frustrated customers.

Polygon has become one of the most prominent solutions to scale Ethereum and offers a variety of products and services that ensure that the blockchain can scale to different demand levels.

Polygon PoS (Proof of Stake)

One of the flagship features of the platform wherein the developers use the Proof of Stake consensus mechanism to process transactions faster and incur lower costs.

Polygon CDK (Chain Development Kit)

A full-fledged Ethereum-compatible sidechain solution that is compatible with the development and provides developers with the means to build a bespoke blockchain network. This interoperability can be used to develop specialized chains that are optimized to specific applications and still interoperable with the rest of the Polygon ecosystem.

Arbitrum is an alternative implementation that achieves high performance by depending on the optimistic rollup technology to achieve the high performance. The solution is off-chain, but it provides the security guarantees of the Ethereum mainnet by means of an innovative dispute resolution mechanism.

The layer 2 solutions have a lot of benefits that help to overcome the basic problems that have been encountered in blockchain networks to date. These can be applied to every member of the ecosystem both to individual users and large scale enterprise applications.

Reduced Cost of Transactions

By off-chain processing transactions and batching them at the time of final settlement on Layer 1, the solutions deliver a huge reduction in the cost per transaction.

Faster Finality of Transactions

• •Blockchain technology is available to a wider application and broader populations
• •Users can actually conduct multiple transactions at a fraction of the cost they would otherwise have to pay on a busy Layer 1 network
• •Wait times are significantly reduced

Maintains Security

This is important when dealing with applications that need real-time interactions and instant feedbacks.

Layer 2 solutions offer developers novel opportunities and tools to build more polished and friendly applications and users of blockchain technologies.

For Developers

With the lower transaction costs and shorter processing time, it is now possible to develop applications that would have been impractical before, because of the network limitations:

• •Applications involving many micro-transactions
• •Real-time interactions
• •More complex computational operations

The ability to migrate existing applications with minimal code changes and achieve an immediate benefit of better performance without major redevelopment efforts opens up whole new categories of decentralized applications and business models.

For Users

• •Reduced transaction costs allow smaller transactions to be completed
• •New applications can be experimented with without involving large amounts of money
• •Enhanced user experience with faster confirmations

These solutions will create additional opportunities to see blockchain technology realize its full potential, supporting a wide range of use cases:

• •Transactions of small scale
• •Large-scale applications deployed on the internet
• •Use cases that are difficult to imagine at the moment

These solutions will not only signify to developers, users, and the wider blockchain community a technical enhancement, but a road to a more convenient, effective, and replicable decentralized future.
