What is Neo (NEO)?
Neo (NEO) is an open source public blockchain from China that supports smart contracts and digital asset issuance. According to the official Neo website, Neo began in 2014 under the name Antshares and was rebranded to NEO in 2017.
Neo was founded by Da Hongfei and Erik Zhang, with early development led by OnChain, a Shanghai-based blockchain company, and Neo is widely described as China's first open source public blockchain. Neo ecosystem work is now split across several bodies, including the Neo Foundation and Neo Global Development (NGD).
Neo is sometimes called the Ethereum of China because of its focus on smart contracts. Neo raised its early funding through two crowdsales, according to official Neo materials, and those sales distributed the token allocation.
What is Neo's smart economy?
Neo describes itself as a distributed network for what it calls a smart economy. The Neo vision combines digital assets, digital identity and smart contracts so that real world assets and rights can be registered and circulated on a blockchain.
Neo's digital identity component aims to standardise electronic identity records for individuals, organisations and entities, linking on-chain activity to the real economy. Observers often note that Neo's design reflects an intent to operate within regulatory frameworks rather than around them.
How do NEO and GAS tokens differ?
The Neo network runs on two tokens, NEO and GAS. The NEO token carries governance rights and, as of September 2026 per the official Neo documentation, has a fixed total supply of 100 million units that cannot be divided into fractions.
The GAS token is the utility token used to pay Neo network fees and execute smart contracts, and GAS is distributed to NEO holders based on holding and voting participation. Unlike NEO, GAS is divisible into fractional amounts.
Neo reaches consensus through delegated Byzantine Fault Tolerance (dBFT), in which council members and consensus nodes elected by NEO holders produce blocks. Neo's dBFT design provides single-block finality, meaning confirmed blocks are not reversed.
What are Neo's strengths and risks?
Neo's commonly cited technical strengths are fast block finality, relatively low fees and support for general purpose languages such as C#, Java and Python. Neo migrated to the NEO N3 mainnet in 2021 according to official Neo announcements, rebuilding its architecture, and later introduced Neo X, an EVM-compatible sidechain.
Neo faces ongoing debate over decentralisation because its set of consensus nodes is small, and its developer ecosystem is often described as smaller than those of leading competing platforms. Neo has also seen governance uncertainty, including public disagreement between its co-founders over foundation management and treasury transparency.
Neo's origins in China mean that shifts in crypto asset regulation across jurisdictions may affect the project. This overview of Neo is for informational purposes only and is not investment advice.
