NEO aims to build a comprehensive "smart economy" by incorporating digital assets, digital identities, and smart contracts. NEO's virtual machine code compiler is designed to support a sizable list of languages including: C#, Java, C, C++, GO, JavaScript, Python, and Ruby. NeoVM is a lightweight, general-purpose virtual machine that is intended to support small programs (e.g. smart contracts) or can be ported into non-blockchain systems. NEO's goals of cross-chain interchangeability features come from NeoX, a protocol that supports cross-chain asset exchange and distributed transactions, which is to say it aims for consistency and executability of transactions across multiple protocols. For its consensus mechanism, NEO relies on delegated Byzantine Fault Tolerance (dBFT), which can support up to 10,000 transactions per second. Validating nodes are randomly selected to confirm on-chain transactions by a collective of book-keeping nodes, which mimics the consensus mechanism of protocols like Stellar in some ways. Chain hard forks are more more complicated under dBFT consensus than Proof of Work (PoW), for example. Users cannot fork the chain at will like under PoW consensus since dBFT requires a two-thirds user majority to operate. NEO also supports two native tokens: NEO and NeoGas (GAS). NEO is a payments token that also confers governance rights over the network's changes and development. GAS is a fuel token for the NEO virtual machine useful for executing smart contracts and supporting applications built on NEO.
