Layer-1 Blockchain

Definition ∞ 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.
Context ∞ Layer-1 blockchains are the subject of constant development and upgrades aimed at improving their performance and utility. News surrounding these networks often details protocol updates, security enhancements, or shifts in consensus mechanisms. Analysts closely follow the evolution of layer-1 blockchains as they are fundamental to the broader digital asset ecosystem and the realization of blockchain’s potential.
