A layer-1 blockchain is a foundational blockchain network that serves as the base infrastructure for decentralized applications and transactions. It operates independently and is responsible for its own consensus mechanism, security, and transaction finality. Examples include Bitcoin and Ethereum. These blockchains form the bedrock upon which other protocols and scaling solutions are built. Their design dictates core aspects of security, decentralization, and transaction processing capacity.
