Da Hongfei is a Chinese technology entrepreneur and one of the best known founders of the NEO blockchain, a smart contract platform that originated as Antshares before rebranding in 2017. He has been a long standing public representative for NEO’s development in Asia and internationally, and is frequently associated with efforts to connect blockchain infrastructure with enterprise and regulatory discussions, including themes such as digital identity and compliant tokenization.
Overview
Hongfei is primarily recognized for co-founding NEO, a public blockchain designed for programmable assets and decentralized applications. NEO is commonly described as a dual token network, using NEO for governance and staking style participation, and GAS as the utility token used to pay network fees. The project has emphasized developer tooling, a virtual machine for executing smart contracts, and a consensus model intended to provide fast finality compared with proof of work systems.
In addition to NEO, Hongfei is associated with Onchain, a China-based blockchain technology company that has worked on permissioned and enterprise oriented frameworks. His public work often frames NEO as infrastructure that aims to support tokenized assets and application deployment while navigating regulatory expectations in different jurisdictions.
History and Background
NEO began as Antshares, a project launched in the mid 2010s during the first wave of public smart contract platforms. Hongfei, alongside co-founder Erik Zhang, helped establish the project’s early architecture and community, with an emphasis on building a developer ecosystem and a distinct technical path relative to Ethereum’s account model and proof of work origins.
In 2017, Antshares rebranded to NEO, adopting the “smart economy” framing that combines digital assets, digital identity, and smart contracts. Over subsequent years, NEO iterated on its protocol design and tooling, including a major network upgrade to NEO N3, sometimes referred to as NEO 3, which introduced a new architecture for fees, governance, and native features intended to support more complex application needs.
Core Products and Services
Hongfei’s influence is most visible in the direction of NEO’s core platform capabilities and ecosystem development. While NEO is an open network rather than a single product company, the project’s roadmap has typically centered on enabling developers to build applications and integrate blockchain features into consumer and enterprise workflows.
- Smart contract platform: Support for building decentralized applications using supported programming languages and NEO’s execution environment.
- Dual token model: NEO for governance and network participation, GAS for transaction fees and smart contract execution costs.
- Governance and staking style participation: Mechanisms for electing consensus participants and participating in network decisions.
- Ecosystem development: Support for wallets, developer tooling, and community programs that help projects launch on NEO.
Technology and Features
NEO’s consensus approach is based on delegated Byzantine fault tolerance, a model designed to deliver deterministic finality, meaning blocks are considered final once confirmed rather than probabilistic as in some proof of work systems. This design can enable faster settlement and predictable confirmation behavior, but it typically depends on a comparatively small set of consensus nodes, which affects decentralization tradeoffs.
NEO’s architecture also includes an execution environment for smart contracts and developer tooling intended to lower barriers to entry for application teams. The N3 era introduced additional native features that many smart contract platforms pursue, such as more explicit governance mechanics and fee design intended to better align resource usage with network costs.

Use Cases and Market Position
Hongfei’s work has positioned NEO as a general purpose smart contract network competing with platforms such as Ethereum and other layer 1 chains. Typical use cases include token issuance, decentralized finance applications, NFT and gaming related deployments, and on-chain governance experiments. NEO has also highlighted themes such as digital identity and asset tokenization, which can appeal to builders exploring regulated or enterprise adjacent use cases.
NEO’s market position has historically been influenced by developer adoption, ecosystem liquidity, and the pace of platform upgrades relative to competitors. Like most smart contract networks, its relevance is tied to whether developers, users, and applications choose to build and remain active on the chain over time.
Funding and Team
NEO’s early growth was supported by token distribution and community driven development typical of mid 2010s blockchain projects. Hongfei has acted as a spokesperson for the project’s strategy and partnerships, while technical leadership has been shared among core contributors, including co-founder Erik Zhang and other engineering leads involved in protocol development, tooling, and ecosystem support.
Risks and Considerations
NEO’s design choices involve tradeoffs that are relevant when evaluating Hongfei’s broader impact. Delegated Byzantine fault tolerance systems can concentrate influence among a limited number of consensus participants, which may raise concerns about decentralization, governance capture, or operational dependencies. The dual token model also introduces complexity, including how GAS fees behave under varying network demand and how incentives align across participants.
As with other smart contract platforms, ecosystem risk includes smart contract vulnerabilities, bridge and wallet security issues, and application level failures that can affect users even when the base protocol operates as intended. Regulatory developments can also shape how networks like NEO are accessed, listed, and integrated by service providers, particularly in regions with evolving policies toward digital assets.
