L1 Blockchains

Architecture

Layer-1 (L1) blockchains represent the foundational infrastructure upon which decentralized applications (dApps) and cryptocurrency networks are built, differing fundamentally from Layer-2 solutions that operate atop existing chains. Their design prioritizes inherent security and scalability, often employing novel consensus mechanisms to achieve higher throughput and reduced transaction costs. This contrasts with relying on a parent chain for security, a characteristic that dictates their suitability for diverse applications, including complex financial derivatives and sophisticated trading strategies. The inherent design choices within an L1’s architecture directly influence its capacity to support on-chain options contracts and other financial instruments, impacting factors like settlement finality and smart contract execution efficiency.
