Top-performing Ethereum Layer 2 solutions like Arbitrum, Optimism, and BASE have outpaced prominent Ethereum competitor Layer 1 blockchains such as Solana and Avalanche in terms of total value locked (TVL) as of September 25, 2023, according to Grayscale. This shift is pivotal as it demonstrates the growing significance of Layer 2 solutions in enhancing the scalability and transactional capacity of the Ethereum network.
Layer 1 refers to the base protocol layer of a blockchain network. It encompasses the fundamental rules governing the network, including consensus algorithms, transaction validation processes, and the creation of new blocks. Layer 1 solutions are integral to the operation of a blockchain and include established networks like Bitcoin, Ethereum, Solana, and Avalanche. However, as blockchain networks grow in popularity, scalability issues arise, often leading to slower transaction speeds and higher fees.
Layer 2 solutions are secondary protocols built atop Layer 1 blockchains, aiming to alleviate scalability issues by offloading transaction processing from the main chain. These solutions retain the security guarantees of the underlying Layer 1 blockchain while providing faster transactions and lower fees. Examples of Layer 2 solutions include Arbitrum, Optimism, and BASE, which operate on top of the Ethereum blockchain.
Layer 2 blockchains operate by processing transactions from decentralized applications (dApps) and subsequently “batching” them together. This batch of transactions is then sent back to the main network in a compressed form for final settlement. This mechanism serves as an auxiliary route or even a dedicated bus lane augmenting a major highway, thus optimizing the transaction process.
By functioning as outlined, Layer 2s enhance the overall usability and transaction potential of the Ethereum ecosystem while still leveraging the network’s fundamental security. As the Ethereum network scales further, a significant amount of activity can transition to the more cost-effective Layer 2 solutions. This transition, in turn, directs value back to Ethereum, further bolstering its position in the blockchain sphere.
Among the 31 active Ethereum Layer 2 projects listed by L2Beat, five projects namely Optimism, Arbitrum, BASE, Starknet, and zkSync are recognized for their standout performance in fundamental metrics. A chart released by Grayscale on September 27, 2023, sheds light on these top Layer 2s by TVL. It’s noteworthy that while Arbitrum and Optimism have launched a token, BASE, Starknet, and zkSync have yet to do so. The market caps column within the chart signifies the market cap for each respective token.
A recent report by Will Hamilogden delves deeper into the landscape of Layer 2s within the Ethereum ecosystem, providing a more extensive understanding of this burgeoning sector. The report is available on Grayscale’s website for individuals seeking a more comprehensive exploration of Layer 2s and their role in scaling Ethereum.
The data from L2BEAT reveals that as of October 2, 2023, the sum of all funds locked on Ethereum converted to USD stands at $10.78 billion, marking a 4.64% growth over the past seven days. The TVL across various projects underscores the growing traction of Layer 2 solutions. For instance, Arbitrum One leads with a TVL of $6.03 billion, followed by OP Mainnet with $2.70 billion, and zkSync Era with $459 million.
The ascent of Layer 2s such as Arbitrum, Optimism, and BASE in terms of TVL is a testament to their value proposition in augmenting the Ethereum ecosystem. By surpassing notable Layer 1s like Solana and Avalanche, these Layer 2s have showcased their potential in fostering a more scalable and cost-effective environment for dApps, thereby contributing significantly to the advancement of the blockchain technology landscape.
