Layer 1
Definition
The underlying main blockchain architecture.
Deep Dive
Layer 1 refers to the foundational, underlying blockchain network that forms the primary infrastructure for an entire cryptocurrency or decentralized application ecosystem. It is the main chain where transactions are processed, blocks are added, and consensus mechanisms (such as Proof-of-Work or Proof-of-Stake) operate to validate and secure the network. Layer 1 blockchains are responsible for establishing the core rules of the network, ensuring data availability, immutability, and decentralization.
Examples & Use Cases
- 1Bitcoin, the original and largest Layer 1 blockchain, known for its robust security and decentralized nature achieved through Proof-of-Work
- 2Ethereum, a prominent Layer 1 blockchain that supports smart contracts and a vast ecosystem of decentralized applications (dApps)
- 3Solana, a Layer 1 blockchain designed for high transaction throughput and low fees, utilizing a unique Proof-of-History consensus mechanism
