Optimism Blockchain

Architecture

Optimism Blockchain represents a Layer-2 scaling solution for Ethereum, employing optimistic rollup technology to enhance transaction throughput and reduce gas fees. Its architecture fundamentally relies on fraud proofs, where transactions are initially assumed valid but can be challenged within a dispute resolution period. This design choice allows for off-chain computation, significantly increasing scalability while maintaining Ethereum’s security guarantees through eventual settlement on the Layer-1 chain. The system’s modularity facilitates ongoing development and integration of new features, positioning it as a key component in Ethereum’s scaling roadmap.
