The Nervos CKB is the base layer of the Nervos Network with the highest security, decentralization, transaction cost and state storage cost. Just like how Bitcoin and Ethereum could scale off-chain with lightening network and plasma solutions, Nervos CKB also embraces off-chain scaling solutions and allow users to preserve and transact assets off-chain. When using off-chain solutions, users and developers can choose their own trade-offs between cost, security, latency and liveness properties.
