Question

Accepted Answer

A Layer 1 (L1) blockchain is the foundational, base-layer network of a decentralized ecosystem, responsible for processing and finalizing all on-chain transactions, establishing the network's consensus mechanism, and acting as the ultimate source of truth for the public ledger. These core protocols, such as Bitcoin and Ethereum, are the primary infrastructure upon which all other decentralized applications and scaling solutions are built.
