Nervos CKB (Common Knowledge Base) is the layer-1 public permissionless blockchain node implementation of the Nervos Network, written in Rust. It uses Proof of Work with an improved Nakamoto consensus and executes smart contracts via a RISC-V compatible virtual machine (CKB-VM).

Use cases

• run a Nervos CKB full node
• participate in the Nervos network as a miner
• verify and settle layer-2 transactions on a layer-1 blockchain
• develop and test smart contracts on the CKB-VM
• query blockchain state via the CKB RPC API
• set up a private CKB devchain for development

When to choose

• you need a layer-1 blockchain focused on verification and decentralization
• you want to run or mine on the Nervos Network
• you need a VM that supports scripting in any language via RISC-V
• you want a PoW chain with improved Nakamoto consensus throughput

When to avoid

• you need an EVM-compatible chain or Ethereum tooling
• you want a proof-of-stake or permissioned blockchain
• you need heavy on-chain computation rather than verification
• you are not working with the Nervos ecosystem
