Layer 1 are the foundation of the crypto ecosystem. They act as the base protocol where transactions are recorded, validated, and secured by a decentralized network of participants. Bitcoin, Ethereum, Solana, and similar networks are examples of Layer 1 blockchains that power thousands of applications and digital assets.Blockchain A Layer 1 blockchain is responsible for processing transactions and reaching consensus without depending on another network. Security, decentralization, and scalability are the three major aspects that define the strength of a Layer 1 protocol.Over time, different Layer 1s have introduced unique solutions: Bitcoin focuses on security and decentralization, Ethereum enables smart contracts, while newer chains like Solana and Avalanche aim for higher throughput and lower fees.These networks form the backbone of decentralized finance (DeFi), NFTs, supply chain systems, and countless other blockchain-based innovations. Without Layer 1, the crypto industry cannot exist.On CryptoShot, we track and analyze every major Layer 1 so you can stay ahead of the market
