Nervos NetworkCKB#421

Nervos is a layered crypto-economy network. Nervos separates the infrastructure of a crypto-economy into two layers: a verification layer (layer 1) that serves as a trust root and smart custodian, and a generation layer (layer 2) for high-performance transactions and privacy protection. This document provides an overview of the Nervos Common Knowledge Base (CKB), a public permissionless blockchain and layer 1 of Nervos. CKB generates trust and extends this trust to upper layers, making Nervos a trust network. It's also the value store of the Nervos network, providing public, secure and censorship-resistant custody services for assets, identities and other common knowledge created in the network. The Nervos Common Knowledge Base (Nervos CKB for short) is a preservation focused, "Store of Assets" blockchain. Architecturally, it's designed to best support on-chain state and off-chain computation; economically, it's designed to provide sustainable security and decentralization. Nervos CKB is the base layer of the overall Nervos Network.
