What Are Layer 1 and Layer 2  Blockchains? A Comprehensive Guide for Beginners

 

Without a doubt, the phrase “blockchain technology” has been trending within the recent years and it is for good reason. It is transforming a number of industries such as Finance, Healthcare, and even supply chain management. However, with the rise in popularity of blockchains comes the issues of slow transactions, expensive fees, and problems with scalability. This is where Layer 1 and Layer 2  blockchains come into action. This blog post is intended for those who may be encountering blockchains for the first time and want to learn more. We intend to cover everything there is to know about Layer 1 and Layer 2 Blockchains in an easy to understand manner. So let’s get started!

Knowing the Fundamentals: What Are Blockchains?

 

Processing blockchains means diving into its layers, but first, lets define what it is. A blockchain is fundamentally a form of storage system that uses blocks to record information, which will chronologically connect to each other like a chain. The most distinct feature about blockchain technology is its decentralized nature, which means that no one organization or individual owns it. Rather, a combination of computers from different regions of the world comprise a network of nodes that maintains the system.

Blockchains are well-known for being the backbone for cryptocurrencies like Bitcoin or Etherum, but their usage stretches much further than that. Blockchains can be used for virtually anything from supply chain monitoring systems, voting technology, even to healthcare information databases. However, the growing popularity of blockchains results in greater challenges, which include unbearably slow transaction speed and exorbitant cost. This is where the First and Second Layer of Blockchains surface.

What is Layer 1 of Blockchains?

 

The layer 1 of a blockchain is its base, which is the whole structure of the blockchain network. Think about the building’s foundation. All activities on the blockchain network are conducted and filmed on the main blockchain. Some of the Layer 1 blockchains include Bitcoin, Ethereum and Solana. These blockchains have their does of blockchains (like BTC for Bitcoin and ETH for Ethereum) as well as use, which means they have their own economy.

The Key Features of Layer 1 Blockchains

 
  • Decentralization: The control of Layer 1 blockchains is distributed, and as a result no one person can control them. Blockchains are thus protected from censorships, which makes them highly secure.
  • Security: Transferring across these blockchains is highly secure and practically impossible to alter, thanks to high-level cryptography.
  • Consensus Mechanisms: Layer 1 blockchains use PoW or PoS to carry out transactions. Bitcoin operates using proof of work and Ethereum previously did but has since changed to proof of stake.
  • Scalability Challenges: The layer 1 blockchains have the major scalability issue more than any other blokchain. While more and more users are accessing the network, the costs and speed start becoming an issue. For comparison, Ethereum grows with approximately 30 transactions while Bitcoin moves with 7.

Let us illustrate using Bitcoin.

 

BTC can be sent and received without needing a financial institution. Each transaction gets documented on the Bitcoin blockchain, which miners who resolve intricate mathematical puzzles maintain. In addition to being decentralized and secure, Bitcoin is also incredibly inefficient; it is slow and very costly to transact. That is why Layer 2 solutions were created.

What is blockchain layer 2?

 

Layer 2 refers to additional structures or protocols constructed on top of Layer 1 blockchains in order to enhance their capabilities. Imagine layer 2 as some sort of enhancement or accessor for making the base layer operate in a more resourceful way. Layer 2 solutions enable the execution of transactions off the primary chain, thereby mitigating the burden on Layer 1 and enhancing scalability.

Most Important Characteristics of Layer 2 Blockchains

 
  • Scalability. Unlike Layer 1 solutions, Layer 2 solutions are able to process several thousands of transactions per second.
  • Lower Costs. Transactions that are processed off the main chain are significantly cheaper, which makes the application of blockchain technology more economically viable.
  • Interoperability. Layer 2 solutions are built to integrate with a number of Layer 1 blockchains which enables effortless movement between various networks.
  • Security. Transactions in Layer 2 solutions are inherently secured by the underlying Layer 1 blockchain making them secure whilst retaining the benefits of Layer 2 blockchain.

A Real Life Application of Layer 2 Blockchain

 

An excellent case of an implementation of payment channels is the Lightning Network with Bitcoin. With the Lightning Network, users can set up payment channels that allow transactions to occur off the main blockchain and later be settled on the primary chain. This allows for near-instant payments at little to no cost. This also allows the Bitcoin network to deal with more transactions than it can handle due to getting overloaded.

What is the synergy between Layer 1 and Layer 2  Blockchains?

 

Layer 1 and Layer 2 of Blockchains work in tandem with each other. While Layer 1 serves as the baseline, Layer 2 enhances the services provided. These are the collaborative efforts:

  • Processing of Transaction: Layer 1 takes care of the essential elements that make blockchain operational, including the maintenance of security, signing, and storing transactions. Conversely, Layer 2 is responsible for off-chain transaction processing.
  • Backup: Layer 1 stores all the transaction data, while in Layer 2 only the information required to transact in a timely manner is stored.
  • Final Settlement: After all these processes are performed on layer two, the transactions are consolidated and submitted back to layer one to complete the settlement. This helps in preserving the security of the whole blockchain system.

Case Study: Ethereum and Polygon

 

Most know Ethereum as a well-established blockchain which operates on Layer 1 and offers the ability to utilize smart contracts. Unfortunately, during the peak of its usage, Ethereum faced network congestion, leading to slower transactions and high gas fees. To fix this, Layer 2 solutions like Polygon started to emerge.

Polygon acts as a Layer 2 scaling solution by processing transactions off-chain and returning them to Ethereum for settlement. This has drastically decreased the transaction cost and increased the speed at which Ethereum processes transactions.

Why Are Layer 1 and Layer 2  Blockchains Important?

 

The synergy between  Layer 1 and Layer 2 blockchains is central to the expected progression of the blockchain. Here’s why:

  • Better Scalability: Because of Layer 2, blockchains can now process a higher transaction volume which makes the technology ideal for mainstream usage.
  • Cost-Effective Transactions: Polygon reduces the load on layer 1 and as a result, Blockchain transactions via Ethereum become less expensive.
  • Improved User Accessibility: The increased speed and reduced fees of blockchain technologies allows for everyday users to have more access.
  • Incremental Innovation: New services and applications can be built on existing blockchains because of layer two solutions which opens new doors for innovation.

Final Remarks: The Perspective Of The Future Of Layer 1 and Layer 2 Blockchains

 

The foundational structure of blockchain technology is still in its infancy, and here is where Layer 1 and Layer 2  Blockchains come into play. They are creating their own cement industry. Blockchains are getting cheaper, faster, and easier to use because of Layer 2 solutions. Together, they are scrambling to ensure that the blockchain technology is adopted in all industries and that users do not have a problem accessing it.

Regardless of experience, every professional in this sphere should know how to work with Layer 1 and Layer 2 Blockchains. Because technology is continually advancing, further development on blockchains will be made so that they are stronger and simpler to use for everyone.
