Arbitrum, a leading Layer 2 blockchain, has recently achieved a significant milestone by surpassing the Ethereum mainnet in daily transaction volume. Over a two-month period, transaction activity on Arbitrum surged by approximately 590%, capturing widespread attention across the cryptocurrency community. This rapid growth can be attributed to two major factors driving its adoption and ecosystem development.
Understanding Layer 2 and Arbitrum’s Position
Since the beginning of the year, Ethereum Layer 2 solutions have been a focal point of discussion in the crypto space. Among these, Arbitrum stands out as the fourth-largest blockchain by total value locked (TVL) in decentralized finance (DeFi), trailing only Ethereum, Tron, and Binance Smart Chain (BSC). As a Layer 2 scaling solution, Arbitrum enhances blockchain scalability and increases transaction throughput, effectively addressing the limitations of Layer 1 networks like Ethereum.
Layer 2, also known as off-chain scaling, focuses on improving transaction speed and efficiency. By handling transactions outside the main chain, Layer 2 solutions reduce congestion and lower fees while maintaining security. Smart contract execution also falls under Layer 2 operations, with platforms like Polygon serving as prominent examples.
On February 21, Arbitrum’s daily transaction volume exceeded that of the Ethereum mainnet for the first time. The number of daily transactions on the network rose from 160,000 on January 1 to 1.1 million by the end of February, marking a growth rate of nearly 590%. This achievement solidified Arbitrum’s leading position among Layer 2 solutions.
What Is Ethereum Layer 2?
In blockchain systems, participants collectively record transactions in a distributed ledger. Computers responsible for verifying and recording these transactions are known as nodes.
While Bitcoin focuses on creating a decentralized ledger, Ethereum aims to build a decentralized computing platform—essentially a world computer. The Ethereum Virtual Machine (EVM) serves as the core of this decentralized computer, enforcing the fundamental rules of the Ethereum blockchain.
In Bitcoin, nodes only validate and record transactions to keep the ledger synchronized. On Ethereum, however, each node must maintain a copy of the EVM. When a user initiates a transaction via a smart contract—a piece of self-executing code—every node performs identical computations to ensure consensus and synchronization.
Although this design ensures security, it requires each node to process excessive information, including smart contract code and data. As a result, transaction speeds remain slow, and fees rise during periods of high demand as users compete to prioritize their transactions.
High fees and slow processing have long been criticized as Ethereum’s major drawbacks. Layer 2 solutions emerged to address these challenges by improving scalability and reducing costs.
Layer 2 refers to off-chain scaling solutions built on top of Layer 1 blockchains like Ethereum. These solutions use sidechains, rollups, or other technologies to process transactions externally, thereby reducing the load on the mainnet. By enhancing transaction speed and capacity, Layer 2 networks significantly improve the user experience.
Exploring the Arbitrum Blockchain
Arbitrum is one of the most prominent Layer 2 solutions in the Ethereum ecosystem. It was developed by Offchain Labs, a company co-founded by Ed Felten, a professor at Princeton University. Like other Layer 2 networks, Arbitrum aims to alleviate congestion and high gas fees on Ethereum.
Arbitrum utilizes Rollup technology, which involves bundling multiple transactions off-chain, processing them, and then submitting the compressed data to the Ethereum mainnet. This approach reduces computational burden on Layer 1, increases overall transaction capacity, and lowers costs—all while maintaining the security guarantees of Ethereum.
Rollup is considered a key technology for Ethereum’s future scalability. Currently, the two major Layer 2 networks using Rollup technology are Arbitrum and its competitor, Optimism. Both employ Optimistic Rollup, a well-established and widely adopted method in the Rollup landscape.
Although Layer 2 ecosystems grew slowly in their early stages, recent months have witnessed explosive growth. The total value locked in Layer 2 networks once paled in comparison to Ethereum, but now Arbitrum alone processes more daily transactions than the Ethereum mainnet.
Currently, Arbitrum boasts a TVL of approximately $5.45 billion, more than double that of Optimism.
ARB Token Economics
The ARB token plays a central role in the Arbitrum ecosystem. With a total supply of 10 billion tokens, ARB has a maximum annual inflation rate of 2%. According to official sources, 12.75% of the total supply was airdropped on March 23, 2023, with 11.62% allocated to users and 1.13% to decentralized autonomous organizations (DAOs).
The distribution of ARB tokens is as follows:
- 17.53% allocated to Offchain Labs investors
- 1.13% allocated to DAOs within the Arbitrum ecosystem
- 11.62% airdropped to users of the Arbitrum platform
- 42.78% allocated to the Arbitrum DAO Treasury
- 26.94% allocated to the Offchain Labs team, future team members, and advisors
Why Is the Arbitrum Network Rising?
Major DeFi Adoptions
According to data from DefiLlama, decentralized exchange (DEX) trading volume on Arbitrum grew by over 22% between March and April. The trading volume on Arbitrum-based DEXs now exceeds that of established chains like BSC and Polygon, ranking second only to Ethereum.
Leading decentralized exchanges such as Uniswap, Sushiswap, and Curve have significantly contributed to this growth. In the past 24 hours, Arbitrum recorded $312 million in trading volume, compared to $258 million on BSC and $128 million on Polygon.
Community Expectations for an Airdrop
Arbitrum’s primary competitor, Optimism, issued its native token OP last year to attract more users. Following this incentive, Optimism’s TVL grew to about 50% of Arbitrum’s, according to L2BEAT.
Arbitrum has adopted a different growth strategy by not initially issuing a native token. Instead, user growth has been organic, driven primarily by increased DeFi activity. However, despite the lack of an official announcement, community speculation about a potential ARB airdrop has fueled user engagement.
Historically, airdrop eligibility often depends on user activity levels. Some analysts believe that the surge in transactions on Arbitrum is partly due to users attempting to qualify for a future airdrop by actively interacting with the network.
Whether leveraging user expectations is part of Arbitrum’s growth strategy remains to be seen as Offchain Labs continues to develop the platform.
