Nervos Common Knowledge Base is an open-source, public blockchain with smart contract functionality. Common Knowledge Byte (CKByte or CKB) is the native cryptocurrency of the platform. In addition to serving as a platform for smart contracts, the network is intended to enable interoperability between diverse blockchain networks.
History[edit]
Nervos was founded by a group of four friends in 2018; Terry Tai, Jan Xie, Kevin Wang, Daniel Lv.[1] The goal of the project was to overcome some of the scaling difficulties faced by Ethereum at the time. The name Nervos is short for "nerves of society."[2]
Nervos raised $28 million in funding in 2018 from venture capital funds including Sequoia Capital.[3] Nervos conducted a crowdsale in October 2019, raising over $72 million USD. Institutional investors included CMB Bank, Polychain Capital, Blockchain Capital, Hashkey Capital, MultiCoin Capital, and Distributed Global.[4] The Nervos Common Knowledge base mainnet launched in November 2019.[4]
The Nervos foundation[edit]
The Nervos foundation was established to bootstrap the Nervos network. In addition to maintaining and expanding Nervos, the foundation conducts research into applied cryptography. The Nervos Foundation has sponsored research, which was presented at conferences such as International Association for Cryptologic Research (IACR), "Design of Symmetric-Key Primitives for Advanced Cryptographic Protocols" in 2019, "Transparent SNARKs from DARK Compilers" in 2020, and "Polynomial IOPs for Linear Algebra Relations" in 2022.[5][6]
Design[edit]
Consensus[edit]
Nervos is based on proof of work consensus.[7] Nervos' consensus method, called NC-MAX, divides transactions into two phases; proposal, and commit. This means that transactions must be fully propagated throughout the network before they can be committed to a block,[8] which eliminates the risk of a "selfish mining attack," whereby one group of miners can increase their own profits at the expense of other miners on the network. The consensus process uses a novel hash function dubbed "Eaglesong" which was developed by a Nervos researcher.[9]
Cell Model[edit]
Nervos’ uses a cell model similar to Bitcoin's UTXO model. A cell is the most basic structure for representing a single piece of data on the blockchain. The data contained in a cell has no restrictions on data type and can include tokens, compiled code, or serialized data like JSON strings. Because the Cell Model is based on the UTXO model, all digital assets, such as CKB, tokens, and digital collectables are the exclusive property of their owner.[10]
CKB virtual machine[edit]
The CKB virtual machine (CKB-VM) is a software-based emulated computer that executes smart contracts on Nervos. Like the Ethereum virtual machine, CKB is a Turing complete development environment, but also integrates the RISC-V instruction set.[11] RISC-V is a computer instruction set similar to the one that powers a computer or a smartphone device. It is also the lowest level of the software stack that provides raw instructions directly to the CPU.[12]
Architecture[edit]
Nervos is based on a multi-tiered design philosophy, where both a base layer and layer 2 infrastructure fulfill different functions.[13] The Common Knowledge Base, or CKB, is the base layer, while much of the transactional data is stored outside of the main blockchain. The protocol is constructed using a modular structure.[14] Godwoken, an Ethereum Virtual Machine (EVM) optimistic rollup, is one of the Layer 2 systems of Nervos, allows developers to use of tools and software developed for Ethereum while directly interfacing with Nervos and utilizing CKB .[15]
