Layer1

Layer 1 refers to the base level of a blockchain network, such as Bitcoin, Ethereum, or Solana, which settles transactions without relying on another network. These protocols provide the underlying security and consensus for the entire ecosystem. In 2026, the L1 landscape focuses on monolithic vs. modular architectures, with high-performance chains like Aptos and Sui pushing the boundaries of parallel execution. This tag explores the evolution of decentralized infrastructure, network security, and the foundational assets driving the Web3 economy.
