NEO is a blockchain platform for building decentralized applications and smart contracts. Founded in 2014 as "Antshares" and rebranded to NEO in 2017, it was one of the earliest major smart-contract projects to emerge from China. This is a neutral explainer.
The dual-token model
NEO's most distinctive feature is that it uses two tokens:
- NEO: represents ownership/governance of the network. Holding NEO is a bit like holding shares — it grants voting rights and generates the second token.
- GAS: the "fuel" used to pay for transactions and running smart contracts. NEO holders receive GAS over time simply for holding.
Why split them? Separating ownership (NEO) from usage fees (GAS)
means transaction costs can move independently of the asset's governance value — a
design choice meant to keep fees more predictable.
Technical character
- Developer-friendly: NEO aimed to let developers write smart contracts in mainstream programming languages rather than learning a new one.
- Indivisible NEO: unlike most coins, the base NEO token has historically not been divisible into fractions.
- Consensus: NEO uses a delegated Byzantine Fault Tolerant (dBFT) mechanism, prioritizing fast finality.
Context to keep in mind
NEO has often been discussed in the context of China's regulatory environment and its ambition around a "smart economy." As with any project, its prospects depend on adoption, competition, and regulation — none of which are guaranteed. Nothing here is a recommendation.

Key takeaways
- NEO is a smart-contract platform with roots in China (since 2014).
- It uses two tokens: NEO for governance, GAS to pay fees.
- Holding NEO generates GAS; the base token is traditionally indivisible.
