Learn about Layer 2 scaling solutions, with 4 examples, and how they improve blockchain processing speed, increasing throughput by offloading work from primary
Bitcoin's average transactions per second have remained relatively unchanged, despite the emergence of scaling solutions like the Lightning Network, which offloads work by allowing users to create channels that remain open as long as needed [1]. The stakes are high, as the ability of blockchain networks to process transactions quickly and efficiently is crucial to their widespread adoption and use.

Layer 1 scaling solutions involve changes to a blockchain's programming or code that allow it to meet increased demand, while Layer 2 scaling solutions involve blockchains or programs that process information for a Layer 1 blockchain, allowing it to meet increased activity levels [1]. For example, Ethereum's Merge, which combined the Beacon Chain with the original Ethereum blockchain, is a Layer 1 scaling solution that enhanced the blockchain's ability to handle varying amounts of activity [1]. In contrast, the Lightning Network is a Layer 2 scaling solution that offloads work from the Bitcoin blockchain, allowing users to create channels that remain open as long as needed [1].
Other blockchains, such as Solana, have also implemented Layer 1 scaling solutions, while Layer 2 scaling solutions like Arbitrum have been built on top of existing Layer 1 blockchains, most notably Ethereum [2]. These solutions process transactions off-chain or in batches before settling them on-chain, dramatically increasing efficiency [2]. The rise of "rollup-centric" roadmaps and Ethereum's proto-danksharding (EIP-4844) has also contributed to the growth of Layer 2 ecosystems [2].
The use of Layer 2 scaling solutions can also impact the tokenomics of a blockchain, as they can increase the throughput of a blockchain without compromising its security and decentralization [1]. For example, the use of rollups can reduce the transaction costs on a blockchain, making it more attractive to users [2].
The significance of Layer 2 scaling solutions lies in their ability to increase the throughput of blockchain networks, without compromising their security and decentralization, and their potential to drive the widespread adoption of blockchain technology [1]. As the demand for blockchain transactions continues to grow, the development of effective scaling solutions will be crucial to the long-term success of blockchain networks.

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.
