What Is A Layer 2 Solution? – How Do They Work?

The use of blockchain is becoming increasingly popular and statistics say that it is only going to rise because more people have embraced the digitization of money.

Achieving important blockchain scalability or the ability to handle loads of requests at the same time is made possible by binary crucial systems which are the Layer-1 solution and the Layer-2 solution. However, the need to vie with legitimate structures of disbursement processing over the years inside the blockchain set-ups has made scalability a necessity for the blockchain domain.

By being scalable, we mean that a blockchain can put up an immensely budding number of operators from different quarters of the world, prerequisite trades, transfers, and other statistics.

The only means by which this can be possible is when blockchain sufficiently combines scalability into its structural system, which, in turn, helps blockchain to maximize its potential as well as raise performance. Layer-1 Solution helps to add utility to the blockchain, which, in turn, ensures the optimization of blockchain performance; however, Layer-2 Solution is altogether a third-party modus operandi that helps to incorporate Layer-1 solution to blockchain to raise operational data.

Blockchain Scalability

Blockchain technology is, without an iota of doubt, demonstrating to be a new leader in the global standing of economic systems. Its decentralized financial status, however, faces a dilemma often referred to as the blockchain trilemma which is the effort made by the blockchain network at balancing the security of the network, as well as decentralization, and scalability within the blockchain system.

Blockchain decentralization refers to the regulation put in place by relevant authorities to ensure the proper use of the blockchain network; With these measures put in place, even the government and monetary organizations can know how much value you are holding in your blockchain account as well as where you send them to. However, blockchain safekeeping implies blockchain procedural protection against the unlawful usage of the blockchain system.

Both factors are painstakingly important and unchanging to the successful task or operations of a blockchain setup. Another important element of importance to the blockchain setup is its scalability which is the ability of the system to back very high transaction output and imminent progression of the system.

How Does it Work?

Scalability is important to the operation of a blockchain rules and is made better with the use of the Layer-2 solution; hence, Layer-2 Solution is of utmost importance to the blockchain set-up. A Layer-2 solution is a tool that maneuvers fundamental blockchain modus operandi to increase scalability and functionality maximally.

There is no doubt that blockchain has become essential support of the financial industry, and many people are embracing the system as the day goes by. Hence, several thousand trades are carried out on the system in a minute. This makes it essential for a system that can handle that number of tremendous transactions without making the system suffer had to be set up and for the blockchain grid; the best resolution is the Layer-2 Solution.

Scalability in this context is the process of insistently shifting a portion of the blockchain operational load to an adjacent system that is so designed to compliment the prowess of the blockchain system. This end-to-end structure is calculated to handle the burden of the system transaction and only gets back to the main blockchain to confirm results/transactions.

Types of Layer-2 Solution

There are various types of layer two solutions.

Nested Blockchains

A Nested Blockchains is characteristically a blockchain within a blockchain setup. The route involves the main blockchain that sets and determines the constraints for a broader network or Layer-2 solutions that can be other than single. This ensures that communications are executed on a unified web of subordinate chains.

A better illustration of the Nested Blockchains is exemplified with a computer network, especially in a situation where several computers are connected to the central PC. They all work together to achieve a common purpose and are synced together to increase functionality. In the blockchain context, many blockchains that act as secondary linkages are synced to the central blockchain to improve scalability, devolution, and security.

The Nested Blockchains ensure that work is evenly distributed and this, in turn, reduces the transactional load on the central blockchain.

The central blockchain acts as the parent’s chain which distributes work among the child chains that maneuver data and then turn it back to the parent chain to complete the transaction thus elucidating a parent-child connection.

State Channels

This is a kind of blockchain network that enables collaborative communication between a blockchain and an off-chain transaction and this, in turn, facilitates speed as well as improves the general operation ability.

Furthermore, this mode of Layer-2 solution does not in any way or at any time require the authentication affirmation of a Layer-1 solution to finish a transaction. However, when an operation or lists of operations are concluded on a state channel, the record of the transaction is stored in the original blockchain.


The sidechain is designed to complete a large consignment of dealings on the blockchain, and it uses self-governing agreement machinery to that of the core blockchain web to achieve maximal speed and, importantly, indispensable scalability. At the same time, the main chain upholds the general safety of the system, data, and disputes as well as authorizes the collection of dealings.


Blockchain technology is without an iota of doubt demonstrating to be a new leader in the global standing of economic systems.

Its decentralized financial status ensures that more people are embracing blockchains and this makes it important for secured and highly scalable blockchain platforms to accommodate the number of clients and the tons of transactions that are carried out on the system, and this has been made possible with the Layer-2 solution.
