Layer-1 blockchain
Layer-1 blockchain refers to the base protocol of a blockchain network that operates independently and can process and finalize cryptocurrency transactions without relying on another blockchain.
Bitcoin was the first Layer-1 blockchain. Others, such as Ethereum, Solana, and Sui, emerged to support more complex decentralized interactions through smart contracts and decentralized applications (dApps).[1][2]
Layer-1 blockchains differ from Layer-2 solutions, which are secondary protocols built on top of Layer-1 networks to enhance scalability and transaction speeds.[3]
