What is NEO (NEO)?

NEO is a blockchain platform built to power a "smart economy" — a digital world where money, contracts, and even your official ID can all live online and run automatically. In simple words, NEO is both a network where developers build apps and a coin (NEO) that gives you a vote in how that network is run. People often call it "the Ethereum of China" because it was one of the first projects to let programmers write smart contracts (small computer programs that run by themselves on a blockchain). Today NEO sits around rank #192 by market value among all cryptocurrencies.

What is NEO in simple terms?

Imagine a giant shared notebook that everybody in the world can read, but nobody can secretly erase or fake. That shared notebook is a blockchain (a record of transactions copied across thousands of computers). NEO is one of these notebooks, but with a special power: it can also run little programs called smart contracts.

A smart contract is like a vending machine. You put in the right amount, press the button, and the machine gives you a snack automatically — no human needed to hand it over. On NEO, developers write these "digital vending machines" to do things like trade tokens, sign agreements, or run games, and they work exactly the same way every time.

NEO's big dream is called the smart economy. The idea is to combine three things: digital assets (money and tokens you own online), smart contracts (the automatic rules), and digital identity (a trusted online version of who you are). Put together, this lets real-world deals — like buying a house or proving you are old enough to do something — happen safely on a blockchain.

How does NEO work?

NEO is actually powered by two coins, which is one of its most unusual features:

• NEO — the main coin. Holding NEO is like owning a share in the network. It gives you the right to vote on decisions and is not divisible (you can only hold whole NEO, not half a NEO).
• GAS — a second coin used to pay fees. Every time you use the NEO network, you pay a small amount of GAS, similar to paying a coin to ride a bus.

Here is the clever part: simply by holding NEO in a compatible wallet, you slowly earn GAS for free over time. So NEO behaves a bit like a savings account that drips out small rewards.

To keep the shared notebook honest, NEO uses a system called delegated Byzantine Fault Tolerance (dBFT). That is a long name for a simple idea: instead of millions of computers competing to confirm transactions, a small group of trusted "bookkeepers" (called consensus nodes) take turns checking and agreeing on each new page of the notebook. Because only a handful of nodes do the work, NEO can confirm transactions quickly and rarely "forks" (splits into two conflicting versions). The trade-off is that it is less spread out than networks where anyone can join the checking process.

Who created NEO and when?

NEO was founded in 2014 in China by Da Hongfei and Erik Zhang. At first the project was named Antshares, and it is often described as China's first public blockchain. In 2017 the team rebranded it to NEO, the name we know today, and broadened its goal toward the "smart economy."

The project is supported by the NEO Foundation and a development community, with Erik Zhang as a key technical leader. Da Hongfei has long been one of the most recognized faces of blockchain in Asia. Knowing this history matters because NEO is one of the older, more established projects in crypto — it has survived many ups and downs since 2014.

What is NEO used for?

NEO is a platform, so its main job is to let other people build things on top of it. Common uses include:

• Building apps: Developers create decentralized applications (apps that run on a blockchain instead of one company's server), often called dApps.
• Creating tokens: Projects can launch their own coins on NEO, the way many small shops can open inside one big mall.
• Digital identity: NEO has long focused on letting people prove who they are online in a secure way.
• Earning GAS: Everyday holders use NEO as a way to slowly collect GAS rewards just for holding.
• Voting: NEO holders can vote for the consensus nodes that run the network, giving the community a real say.

A major upgrade called NEO N3 (also written Neo N3) launched in 2021. It rebuilt the network to be faster, cheaper, and friendlier for developers, adding built-in features like an oracle service (a way for smart contracts to safely read information from the outside internet) and a naming system that turns long wallet addresses into simple, readable names.

What makes NEO different?

Plenty of blockchains run smart contracts, so why does NEO stand out? A few reasons:

• Two-coin design: Splitting the network into NEO (ownership and voting) and GAS (fees) is unusual and lets holders earn rewards passively.
• Developer-friendly: NEO lets programmers write smart contracts in popular, everyday programming languages, so they do not have to learn a brand-new one from scratch.
• Speed and order: Thanks to dBFT, transactions become final quickly and the chain almost never splits, which is handy for serious business uses.
• Long focus on identity and regulation: From the start, NEO aimed to work with rules and digital ID rather than around them, hoping to bridge crypto and the official economy.

How do you buy and store NEO?

You can buy NEO on many cryptocurrency exchanges (online marketplaces where you swap regular money or other coins for crypto). The basic steps are usually:

• Create and verify an account on a trusted exchange.
• Deposit money or another cryptocurrency.
• Search for the ticker NEO and place a buy order.

After buying, you can leave NEO on the exchange or move it to your own crypto wallet (an app or device that stores the secret keys controlling your coins). A wallet you control is often safer, and remember: to earn GAS rewards, your NEO usually needs to sit in a wallet or service that supports those rewards. Whatever you choose, never share your secret recovery phrase with anyone — it is the master key to everything you own.

Is NEO safe? Risks to know

The NEO network has run since 2014 and uses a battle-tested consensus system, but no crypto is risk-free. Things to keep in mind:

• Price swings: The value of NEO can rise or fall sharply and quickly.
• Fewer nodes: Because dBFT relies on a small set of consensus nodes, the network is more centralized than some others, meaning you trust a smaller group.
• Competition: Many smart-contract blockchains exist, and NEO must keep attracting developers and users to stay relevant.
• Your own security: If you lose your recovery phrase or fall for a scam, your coins can be gone for good.

None of this is financial advice — it is just the honest picture. Always do your own research before buying any cryptocurrency.

Is NEO the same as Ethereum?

No. They are separate, competing networks that both run smart contracts. NEO is its own blockchain with a different design, a two-coin system (NEO and GAS), and its own community. The "Ethereum of China" nickname just points to their similar goals.

What is the difference between NEO and GAS?

NEO represents ownership and voting power in the network and comes in whole units only. GAS is the fuel used to pay transaction fees, and you earn it gradually just by holding NEO.

How many NEO coins are there?

NEO has a fixed maximum supply of 100 million coins, all created when the network launched. Because the supply is capped, no new NEO can be mined later.

Can I make money holding NEO?

Holding NEO lets you earn small amounts of GAS over time, and the price of NEO itself can go up or down. But crypto is volatile and nothing is guaranteed, so only consider what you can afford to lose and do your own research.
