The Nervos Common Knowledge Base (CKB) is a public, permissionless blockchain serving as layer 1, the bottommost layer, of Nervos Network.
The Common Knowledge Base is designed to maximize flexibility, security, and decentralization. The Common Knowledge Base creates a layer of trust that extends to all layers that build on top of it. This provides a solid foundation for the Nervos ecosystem to be based on.
In a blockchain context, “common knowledge” refers to pieces of state information that are verified by global consensus. The Nervos CKB is, in a sense, a state verification system.
Nervos Network separates its blockchain infrastructure into two distinct layers: a verification layer (layer 1) that serves as the trust root and smart custodian, and a generation layer (layer 2) for high-performance transactions and privacy protection.
