What is NEO

NEO is a non-profit community-based blockchain project. It is a distributed network that uses blockchain technology and digital identity to digitize assets, uses smart contracts to automatically manage digital assets, and realizes a "smart economy".
NEO was officially established as a project in 2014 and open sourced in real time on Github in June 2015. Since its establishment, the NEO team has experienced the highs and lows of the blockchain industry, and the frenzy and cooling of the digital currency market. We believe that technology is the driving force behind the changes of this era. Driven by this power, we will enter a new era of "smart economy".

 NEO Technical Features

The bottom layer of NEO supports a variety of digital assets. Users can register and distribute assets on NEO themselves, and trade and transfer them freely.

Support digital certificates to solve the trust problem of public chains. Digital certificates can be used to issue assets on the blockchain legally and compliantly and enjoy legal protection.

The superconducting trading mechanism can realize a trustless digital asset exchange and match various digital assets without the need for recharge.

Turing-complete smart contracts are executed in NeoVM and have many advantages such as determinism, terminability, resource control, concurrency, sharding and unlimited expansion.

NEO Intelligence supports development with programming languages such as C, Java, and Go. Developers can quickly develop smart contracts based on the NEO blockchain without learning new languages.

NeoVM: NEO's lightweight stack-based virtual machine has fast startup time and high execution efficiency. With "deterministic call tree" technology, it can achieve theoretically unlimited scalability.

The original dBFT consensus mechanism uses a Byzantine fault-tolerant algorithm to reach a consensus among consensus nodes to ensure the finality of transactions, and can ensure that the system still has finality and availability when less than one-third of the nodes suffer Byzantine failures.

Cross-chain interoperability protocol, including cross-chain asset exchange protocol and cross-chain distributed transaction protocol, can realize atomic-level asset exchange between multiple blockchains, and can also jointly execute smart contracts on multiple blockchains and guarantee Transactional consistency.

Introducing signature and encryption technology based on Lattice (lattice cryptography) to reduce the encryption and decryption problem to the SVP (shortest vector) problem that quantum computers cannot yet solve, thereby preventing the "quantum crisis".

How will NEO outline the future?

digital assets

Digital assets are programmable assets that exist in the form of electronic data. The use of blockchain technology to realize asset digitization has the characteristics of decentralization, deintermediation, trustlessness, traceability, and high transparency. NEO
Supporting multiple digital assets at the bottom level, users can use NEO
Self-register assets on the Internet, trade and circulate freely, and solve the mapping relationship with physical assets through digital identity. The assets registered by users through compliant digital identities are protected by law.

digital identity

Digital identity refers to the identity information of individuals, organizations, and things in the form of electronic data. The current relatively mature digital identity system is the X.509 standard based on PKI. In NEO, we will implement a set of compatible
X.509 digital identity standard. This set of digital identity standards, in addition to being compatible with the X.509 hierarchical certificate issuance model, will also support the Web Of Trust-style point-to-point certificate issuance model.

smart contract

The biggest feature of the NeoContract smart contract system is its seamless integration with the existing developer ecosystem. Developers do not need to learn new programming languages. They can use mainstream programming languages such as C and Java in familiar IDEs.
Develop, debug, and compile smart contracts in the environment (Visual Studio, Eclipse, etc.). NEO's universal lightweight virtual machine NeoVM
It has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system allows millions of developers around the world to quickly develop smart contracts. NeoContract
There will be a separate white paper describing the implementation details.
