Neo Review 2026: NEO and GAS Smart Contract Blockchain

Neo is an open-source, community-driven blockchain platform for decentralized applications and digital assets. It was previously known as AntShares and is sometimes called the "Ethereum of China" because it offers smart contracts and developer tools in a similar spirit. Sources give different dates for its start: one exchange page says 2016 under the AntShares name, while another says 2014 with a rebrand in 2017.

The design uses two tokens. NEO is the network and governance asset, and GAS pays for transactions and computation. It runs on a delegated Byzantine Fault Tolerance consensus mechanism and a lightweight virtual machine called NeoVM. Built-in services include NeoID for digital identity, NeoFS for distributed storage and an oracle system.

The project is still referenced in recent exchange guides, and a video title in public reporting mentions a Neo X testnet release. The project's own homepage was not available, so details such as the current version, validator set and ecosystem size are not confirmed here.

Neo is a layer-1 blockchain, meaning it has its own network of nodes and its own native tokens. Developers write smart contracts that run on the NeoVM, and users send transactions that are recorded on the chain.

Transactions are validated through dBFT, a consensus design where a limited set of nodes agree on each block. NEO holders take part in governance by voting on proposals and changes, and staking is how holders participate in network rewards. GAS is the fuel: it pays for computation and transactions and is described as being distributed to people who hold NEO.

On top of the base chain, the platform describes extra services: NeoID for decentralized identity, NeoFS for distributed storage, and an oracle system for outside data. A video title in public reporting also points to Neo X, an extension that was at testnet stage at the time of that release.

Neo does not use a single fee schedule in the material available here. Network activity is paid for in GAS, which is used to pay for transactions and computation. Specific per-transaction costs are not stated.

If you buy, swap or stake NEO through an exchange app, that platform sets its own trading fees, spreads and reward terms. One US exchange mentions possible zero trading fees under a loyalty program up to a tier limit, with other fees and spread still applying. Check the fee screen in your wallet or exchange before you confirm anything.

Public sources do not include audit reports, a bug bounty or incident history for the Neo network, so none are claimed here. Neo's consensus relies on a limited set of nodes, which is a design trade-off for speed that readers should weigh against more widely distributed validator sets.

If you stake or hold NEO on an exchange, you are exposed to that company's custody and regulatory risk, and exchange security measures refer to account access, not protection from price losses. Self-custody puts key safety on you, so back up your recovery phrase and verify wallet software. Crypto assets are volatile and staking rewards are not guaranteed.

Neo fits developers curious about an alternative to Ethereum-style platforms and long-term holders who want NEO and GAS exposure, including exchange staking. It is less suited to anyone who needs audited, independently verified performance data before choosing a chain.
