NEO – An Open Network For Smart Economy

NEO is a non-profit community-based blockchain project that utilizes blockchain technology and digital identity to digitize assets, to automate the management of digital assets using smart contracts, and to realize a “smart economy” with a distributed network.

NEO was founded in 2014 and was real-time open source on GitHub in June 2015. Since its inception, the NEO team has experienced the upsurge and boom of the blockchain industry and the frenzy and cooling of the digital money market. We believe technology drives progress and together we can create the future. Motivated by this, NEO has been created to shift our traditional economy into the new era of the “Smart Economy”.

Digital Assets

Digital Assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the NEO blockchain, users are able to register, trade, and circulate multiple types of assets. Proving the connection between digital and physical assets is possible through digital identity. Assets registered through a validated digital identity are protected by law.

Digital Identity

Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form. The more mature digital identity system is based on the PKI (Public Key Infrastructure) X.509 standard. In NEO, we will implement a set of X.509 compatible digital identity standards. This set of digital identity standards, in addition to a compatible X.509 level certificate issuance model, will also support the Web Of Trust point-to-point certificate issuance model.

Smart Contract

The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language, but can use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO’s Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts. NeoContract will have a separate white paper describing the implementation details.

NEO Cryptocurrency Other Features

Better Scalability: Distributed Storage Protocol – NeoFS
When competing with traditional technology solutions, scalability is the handicap of blockchain technology. In order to have a censorship-immutable and trust-free system, blockchains such as Bitcoin compromises latency and throughput in its design.

NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes. The old block data can be stored in NeoFS, so that most of the full nodes can release the old data for better scalability and at the same time, ensure the integrity of historical data.

At the moment, the block generating rate is manually set at 15 seconds. With low enough latency in inter-nodes connection in the future, most blocks will be generated by every 1 second. With the bandwidth at 100Mbit/t and external cryptographic computing hardware, NEO Blockchain is capable of handling thousands, if no tens of thousands, of transactions per second.

Innovative dBFT consensus mechanism
Consensus nodes use Byzantine Fault Tolerance(dBFT) Algorithm to reach consensus and ensure the finality of transactions. The system is operable as long as less than 1/3 of the nodes are dishonest. It is also ensured that the system keeps its finality, meaning that once confirmations are final, the block can not be bifurcated, and the transaction will not be revoked or rolled back. (more)

Cross-chain interoperability protocol – NeoX
This protocol allows multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together.

It is possible by creating a contract account for each participant using the NeoContract function. Any chain should be compatible with NeoX as long as they are compatible with NeoContract or can provide simple smart contract functionality.

Quantum-computer-proof technology: NeoQS
The emergence of quantum computers creates a major challenge to RSA and ECC-based cryptographic mechanisms. For quantum computers can solve thses cryptographic prblems in an extremely short time. Using Lattice-based cryptograph signature and encryption technology, NeoQS can prevent the quantum crisis as Lattice-based cryptography provides encryption problems (e.g. SVP) beyond the capability of quantum computers.
