Over 100 Layer 2 networks emerge, with Ethereum's Optimism and Bitcoin's Ark protocol aiming to improve scalability, speed, and cost, with a potential impact
Ethereum's layer-2 blockchain, Optimism, has been working to alleviate issues of scaling, speed, and costs, with its CEO and co-founder, Jing Wang, stating that the mission to scale Ethereum is ongoing [1]. The layer-2 blockchain aims to focus on scaling and speed, while also lowering costs for users, making it 10 times cheaper to interact with Ethereum's chain through its own network [1].

The surge in layer-2 solutions has raised important questions about necessity, sustainability, and the future of blockchain scaling [3]. Ethereum's Dencun upgrade challenged many layer-2 solutions with a significant drop in network fees, making Ethereum more affordable [3]. However, the layer-2 race is now about attracting the right business, with over 100 layer-2 networks emerging, including Bitcoin's Ark protocol [2]. Ark offers an alternative scaling approach that allows users to send and receive funds without liquidity constraints, making it easier for recipients to get paid without an onboarding setup [2].
The Ethereum Virtual Machine has established itself as the de facto standard for chain development, with Vitalik Buterin envisioning a future where layer-2 solutions play a crucial role in scaling the network while maintaining its decentralized ethos [3]. Optimism's Superchain vision is an attractive approach to scaling, creating an interconnected network of rollups sharing security and interoperability features [3]. Other layer-2 solutions, such as Uniswap's Unichain and Kraken's Ink, are also emerging, with some targeting specific purposes that aren't well-served by existing solutions [3].

The emergence of over 100 layer-2 networks has significant implications for the future of blockchain scaling, with the potential to improve scalability, speed, and cost [3]. However, the rapid proliferation of layer-2 solutions also raises concerns about necessity, sustainability, and the potential for a shake-out in the market [3].

By moving transaction volume off the main chain, Layer 2s have reduced the number of fees burned, which has slowed the deflationary pressure on the ETH supply.
State channels reduce transaction latency and costs by allowing users to conduct interactions off-chain while maintaining the security of the underlying blockchain.
Investors worry that Layer 2s capture significant profits while contributing relatively little back to the mainnet, potentially weakening the main chain's economic utility.
The Pectra upgrade aims to improve institutional and retail accessibility by increasing blob capacity and introducing account abstraction, allowing users to pay gas fees with stablecoins.
