Nervos designed a radically decoupled decentralized platform to allow multiple paths of scalability, transaction certainty and low local latency.
Nervos is a suite of scalable and interoperable protocols and an open blockchain "Trustware" platform for decentralized applications. Trustware is a new decentralized computing paradigm that goes beyond distributed ledgers and smart contracts, to bring general expression of trust to meet the demand of today's real world applications. In contrast to smart contract platforms, Nervos uses the "Common Knowledge Base", a simpler state machine with uniform state transition semantics for superior scalability, interoperability and better aligned incentives for all participants of the network.
Current blockchain technologies (such as Bitcoin and Ethereum) pursue extreme decentralization, requiring full nodes in the network to be completely equal peers. This imposes constraints on the design of blockchain systems, making it harder for them to meet the demands of real world applications. The hardware cost of running full nodes becomes ever more expensive with the inflation of on-chain states. There are less and less users who are willing to run full nodes.
Nervos supports more general-purpose computation and storage, comes with better scalability and more balanced economic incentives, and is more friendly to mobile devices.
The paradigm consists of the following components:
DApps in the CKB use Types to define the appropriate data structure and store application data in Cells. The application logic is implemented with Generators, and the state validation logic is implemented with Validators. Generators run on the client side to generate new states, which get packaged into transactions and broadcast to the entire network. Consensus nodes in CKB network first authenticate the submitter of the transaction, then validate new states in the transaction with Validators, and put valid transactions in the transaction pool. Once a new block is generated and received, new states in the block are comitted into the CKB.
