Layer 2 Solvers

Architecture

Layer 2 solvers represent a suite of architectural designs aimed at scaling blockchain networks, particularly Ethereum, by processing transactions off-chain while maintaining security and finality on the main chain. These solutions typically involve creating separate, parallel chains or structures that handle a significant portion of transaction volume, reducing congestion and lowering fees on the primary Layer 1 network. The core principle involves periodically settling the state of the Layer 2 network back onto the Layer 1, ensuring data integrity and preventing double-spending. Different architectures, such as rollups and sidechains, employ varying mechanisms for this settlement process, each with distinct trade-offs regarding security, scalability, and compatibility.
