Layer 2 Blockchains Explained for Investors
Blockchains have rapidly become a critical component of various industries over the past decade. However, one challenge has limited their widespread adoption: scalability. As the number of users of blockchains increases, the number of transactions on the blockchain increases as well. This, in turn, creates challenges with congestion, fees, and the processing speeds of blockchain networks.
To address these critical issues, developers have created Layer 2 networks. These networks allow for transactions on the blockchain to be processed more efficiently, allowing blockchains to handle a greater number of transactions each day.
Layer 2 blockchains have developed as one of the most important innovations in the blockchain world. They allow individuals and industries to engage in decentralized transactions without sacrificing scalability.
For investors, the industry of Layer 2 blockchains represents one of the fastest-growing segments of the digital asset industry.
What Is a Layer 2 Network?
A Layer 2 network is a blockchain protocol that exists on top of an existing blockchain protocol, also known as a Layer 1 blockchain.
Instead of processing the transactions for a blockchain directly, a Layer 2 network can manage the transactions for that blockchain on behalf of its users. The transactions are then submitted to the Layer 1 blockchain for processing. By creating a Layer 2 network for a blockchain, that blockchain can experience an increase in:
Transaction throughput
Network efficiency
Scalability
User experience
Transaction costs
The security of the underlying blockchain remains intact.
Why Does Scalability Matter?
As the number of individuals that adopt blockchains and use their features increases, the blockchains must process an increasing number of transactions.
If a blockchain does not feature improvements in scalability, it can lead to an increase in:
Transaction fees
Network congestion
Decreased transaction processing speeds
Decreased performance of the blockchain applications
Layer 2 solutions help alleviate these issues for users.
How Do Layer 2 Solutions Work?
The processes that occur within a Layer 2 network may differ from blockchain to blockchain. However, the general functions of a Layer 2 solution are similar:
Processing transactions independently of the blockchain
Grouping transactions together
Verifying the accuracy of transactions
Submitting information to the base blockchain
By processing transactions independently of the base blockchain, there is an increased efficiency in moving the transactions from user to user.
This processing allows for decentralized applications to handle significantly more users.
What Benefits Do Users Receive from Layer 2 Networks?
Users that adopt Layer 2 networks benefit from a range of features and advantages, including:
Lower costs for transactions
Faster transaction settlements
An increased transaction capacity
An improved performance of decentralized applications
A better user experience with decentralized applications
An increased efficiency in the blockchain itself
These features make the blockchain a more practical tool for various financial and commercial applications.
Businesses benefit from the ability to create blockchains that can manage a large number of users.
How Have Layer 2 Networks Developed for Decentralized Finance (DeFi)?
Layer 2 blockchains have also become essential components of decentralized finance or DeFi applications, including:
Digital asset trading platforms
DeFi lending platforms
DeFi borrowing platforms
Stablecoin transfer platforms
Liquidity pool applications
Payment applications
By decreasing the cost of transactions on these platforms, Layer 2 blockchains allow users to engage with decentralized finance more frequently.
As decentralized finance becomes a more prominent industry within the blockchain, increased scalability becomes even more valuable.
How Have Layer 2 Blockchains Developed for Gaming and Digital Assets?
Another of the growing industries that utilizes blockchains is the gaming and digital assets space. To handle the high number of transactions created by gaming applications, a Layer 2 solution allows these projects to process the transactions more efficiently.
Some of the most common applications of Layer 2 technology include:
Support for digital assets
In-game transactions
Marketplaces for in-game items
Digital collectibles
Virtual in-game economies
The improvements in scalability and reduced transaction costs make for a better experience for players and supporters of the gaming world.
How Can Layer 2 Technology Benefit Enterprises?
An increasing number of enterprises are exploring the use of blockchain technology. However, many of these enterprises require a blockchain that can manage a high volume of transactions.
Some of the uses of blockchain technology for enterprises include:
Supply chain management
Cross-border payments
Loyalty programs
Identity verification
Asset tokenization
The scalability that Layer 2 blockchains offer to enterprises will result in increased efficiency in their operations and reduced costs of implementing blockchain technology into their current organizations.
What Are the Major Challenges Facing Layer 2 Blockchains?
Despite the benefits that Layer 2 blockchains offer to the cryptographic world, these networks face a few challenges.
Some of the challenges include:
Need for increased user education
Liquidity fragmentation
Interoperability between various blockchains
Security of the smart contracts on the blockchain
Adoption of blockchain technology by developers
Regulations for the blockchain and DeFi industries
Though many of these challenges exist, improvements to the infrastructure of Layer 2 blockchains will eventually allow them to overcome these challenges over time.
Increased interoperability between blockchains is a challenge and a priority for the industry.
Why Should Investors Care About Layer 2 Blockchains?
Though not an investment project itself, Layer 2 blockchain technology is one of the most important infrastructure developments of the industry to date.
The industry of Layer 2 blockchains may influence the growth of the entire digital asset and decentralized industry, including:
Adoption of blockchain technology
Digital asset usage
Decentralized finance
Tokenized financial products
Enterprise blockchain solutions
As such, investors who are interested in the growth of the blockchain world should pay close attention to the Layer 2 blockchain developments.
