Nervos Network is a public blockchain and collection of protocols that aim to solve the scaling limitations facing traditional networks like Bitcoin and Ethereum. Nervos' blockchain is a layer-1 protocol that uses Proof-of-Work (PoW) consensus and supports smart contract development. It also consists of a series of layer-2 scaling solutions to facilitate high-volume use cases. Nervos' native token (CKByte or CKB) allows users and developers to claim storage space on the Nervos blockchain in proportion to their holdings. Layered Design Nervos is a layered network that consists of a base general computation and consensus layer and a series of application layers. The first layer is Nervos' CKB mainnet that features Proof-of-Work (PoW) mining for security. It works in tandem with the layer-2 protocols. Nervos CKB stores the network's state (account balances and application activity) in cells, whereas Nervos' layer-2 protocols process transactions and generate new states. Nervos CKB also provides a stateful Turing-complete virtual machine (VM) to support and process applications built using smart contracts. The CKB VM uses a cell model (based on Bitcoin's UTXO accounting model) to store and track state changes. This cell model facilitates the parallel processing of transactions and allow for the integration of light clients. Nervos' layer-2 protocols use the security provided by the base layer but can execute transactions faster and inexpensively relative to Nervos CKB. They can also serve as application-specific protocols with feature sets that cater to a particular use-case like privacy or finance. Core Design Principles Some of the core principles that led to the design of the Nervos Network include: A layer-1 blockchain's native asset must be a store of value. Pushing scaling responsibilities to the second layer is preferable because layer-1 chains should be open and accessible. Designing for scalability at the base layer leads to compromises in decentralization and, sometimes, security. Instead, layer-1s should complement and not compete with layer-2 solutions. Proof-of-Work (PoW) as a Sybil resistance method is essential for layer-1 blockchains. The layer-1 blockchain must provide a generic programming model for interactive protocols (composability) and to facilitate communication between different layer-2s (interoperability). State storage has to have a clear and fine-grained ownership model to avoid the "tragedy of the commons" problem. State occupation must have an ongoing cost to deliver consistent long-term rewards to miners regardless of transaction demand. Muta Layer-2 Framework Muta is a proposed framework for building Nervos-based layer-2 blockchains. Muta chains will use Nervos CKB at their base but enabled developers to custom build a sidechain with distinct features, such as a Proof-of-Stake (PoS) or Delegated Proof-of-Stake (DPoS) design. Nervos developers created Muta to improve overall network performance (through the parallelization of computation), enable the development of customizable layer-2 chains, and unlock interoperability between other EVM or WASM-based networks. Muta is still in beta. Lumos App Framework Lumos is a JavaScript/TypeScript based application framework for Nervos CKB. It aims to simplify application development on Nervos. Lumos is still a work in progress.
