Nervos Network(CKB)

Overview

Nervos Network is a layered public blockchain project that separates its architecture into a verification layer (layer 1) and a generation layer (layer 2) for higher-throughput transactions. The layer 1 component, the Nervos Common Knowledge Base (CKB), is a permissionless blockchain intended to store assets, identities, and other data created across the network.

CKB is designed around on-chain state storage combined with off-chain computation, and it uses a proof-of-work consensus mechanism. Its native token, CKByte (CKB), is used to pay transaction fees and to occupy on-chain storage space, so token holdings correspond to the amount of state a user can store.

CKB uses the Cell model, an extension of the UTXO model that allows cells to hold arbitrary data and scripts. The mainnet launched in 2019, and subsequent development has included extension layers aimed at interoperability with the Bitcoin ecosystem.
