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].

Public Layer 1 blockchains have limited block space, leading to high fees and slow confirmations when demand exceeds capacity; L2s alleviate this congestion by processing transactions off‑chain.
They submit cryptographic proofs or compressed summaries of bundled transactions to the Layer 1, which validates and finalizes the state changes, preserving the base layer's security guarantees.
The primary types are state channels, which lock funds in a contract for off‑chain trades, and rollups, which execute and aggregate transactions off‑chain before posting proofs to the L1.
