Greenfield from Testnet to Mainnet

Blog post image.

BNB Greenfield is a novel decentralized data storage network that builds upon the many advantages these systems have to offer and is designed to transform the way everyday users interact with their own data. 

BNB Greenfield’s journey began on April 10th, 2023, with the launch of its Congo Testnet, and since then, 5 months have passed and a ton of progress has been made! The BNB Chain community have diligently pushed forward the technological advancements and fostered the ecosystem, all culminating in the awaited introduction of the BNB Greenfield Mainnet.

After months of development and testing, BNB Greenfield Mainnet is nearly ready to introduce an entirely new structural and economic paradigm for data in the Web3 era. Making the ownership, usage and monetization of data easier for users, both within and beyond the Web3 ecosystem. Read on to discover the milestones we have covered on our path to the upcoming launch of BNB Greenfield Mainnet.

The Stepping Stone: Testnet Achievements

BNB Greenfield’s Testnet has been rigorously evaluated and tested by the BNB Chain Community over a 6 month period. During this test phase, the network has processed more than ~200,000 on-chain transactions, welcomed community developers and was connected to 150,000 unique wallet addresses (as of date, with greenfield scan URL). The BNB Greenfield network also received massive support from the broader ecosystem, with multiple storage providers deployed on our Testnet, such as NuLink, and 4EVERLAND. Here are some highlights.

Outstanding Speed for uploading and downloading


The decentralized network of storage providers (SPs) streamlines data management by using the Primary SP role to simplify both uploading and downloading. It ensures fast, user-friendly uploads with breakpoint resumable capabilities for efficient bandwidth use and provides stable, high-speed downloads. Additionally, the SP’s meta-service offers high-performance search functions to meet complex logic requirements. For more information: link

During the testnet, the dev team have executed several rounds of stress testing, during which the uplink bandwidth reached 30M/sec and downlink bandwidth reached 300M/sec. Each SP is able to upload 30 files/sec.

Privacy and Access Control

BNB Greenfield itself is a storage-oriented blockchain interacting with a decentralized network of storage providers (SPs). Users upload their data with unique access and usage permissions. Storage providers store that data off-chain with proper redundancy and backup. Metadata of the user’s assets is stored on the BNB Greenfield blockchain. The ability to uniquely configure permissions on data in a native smart-contract-enabled environment is the mechanism that enables myriad potential business models that will benefit users and other BNB Greenfield participants. 

As all GNFD resources are mapped as NFT. Resources such as buckets, objects, and groups can be mapped as ERC721 tokens, thus developers can fully reuse the ERC721 interface for general permission management without introducing any additional complexity. A data marketplace can now easily be built where users can freely create, list, trade, and sell data assets, including digital publications, scientific experimental data, and specific domain data. Here is the demo link: The related codebase repo are open source here and here

Cross-Chain Programmability

BNB Greenfield has a native programmable layer between BNB Smart Chain that allows existing BNB Chain dApps to leverage appropriately permission data, and give rise to a new generation of BNB Greenfield dApps built on BNB Smart Chain that will either help users interact with the BNB Greenfield ecosystem or become data products or services in their own right – managing, configuring and composing data stored by SPs at scale. The ability to uniquely configure permissions on data in a native smart-contract-enabled environment is the main logic that enables myriad potential business models on BNB Greenfield.

Greenfield also introduces the concept of “Mirroring” to  transfer control over objects stored on BNB Greenfield to a smart contract on BNB Smart Chain (BSC). If an object is mirrored, this object can be managed through BSC by sending messages to Greenfield through a network of relayers, which facilitate communication and interaction between the two platforms. This design allows users or other smart contracts to perform various operations and changes to the object through on-chain transactions.

Comprehensive Infrastructure and dApps Builders

Here are just a few of the many use cases the BNB Greenfield Mainnet will bring and the BNB Chain architecture will support:

  • Web Hosting: As a web developer, you may be familiar with hosting services like WordPress and Wix. BNB Greenfield will allow any storage provider on BNB Greenfield to act as a web hosting provider. Websites can be created without restriction and accessible to anyone in the world – enabling a new level of internet freedom and equality. 
  • AI + Web3: 
    • NFPromptNFPrompt is the AI-powered entry point to Web3, the first AI-UGC platform that allows users to effortlessly create amazing NFTs, vote and earn rewards for art contests. At the same time, sponsoring brands/projects achieve accurate and in-depth super-Marketing with a broad Web2+3 user base. By integrating with Greenfield, NFPrompt champions user-generated content and complete ownership. 
    • GlacierGlacier is building a composable, modular and scalable L2 data network for large-scale Dapps. Glacier empowers decentralized apps (DApp) to build on decentralized databases (DDB). It provides programmable data composability powered by opBNB solution to seamlessly and effortlessly handle datasets with NoSQL GlacierDB on top of BNB Greenfield. BNB Chain’s native smart-contract ecosystem empowered web3 users to master the art of data management with confidence.
  • Data Marketplace: Data marketplace is a data exchange platform where users can freely create, list, trade, and sell data assets, including digital publications, scientific experimental data, and specific domain data. BNB Greenfield developers just need to use smart contracts, greenfield APIs, and pre-defined rules to avoid complex backends.
    • Codex Field: By leveraging BNB Greenfield’s decentralized infrastructure, CodexField empowers developers with true ownership and control over their code assets. CodexField’s Code Marketplace not only benefits developers but also code consumers, creating a mutually beneficial ecosystem where quality code thrives.

Supportive Greenfield Developer Community 

To further strengthen the developer community and onboard more developers,  the Hackvolution hackathon was launched on July 13. This year we were fortunate to witness a lot of innovative projects. Greenfield projects win prizes in Infura category, namely Codex FieldRIDO and Green Gate.  Greenfield Mobile also wins Projects with Potential Awards. 

The BNB Chain Wishlist Program offers a repository to nurture visionary endeavors and make a meaningful impact on the BNB Chain’s development. Whether exploring novel technologies, devising cutting-edge solutions, or revolutionizing decentralized applications, you can find the most demanding and innovative areas.

Beginning of a New Era: Launch of the Mainnet

The Greenfield blockchain utilizes on-chain governance to select validators and SPs. There is also a Provisional Governance Framework that provides the structure for sustainable, adaptable, and democratic governance to endure and evolve. Further details on the governance module are explained here.

BNBChain Community like BNB Chain core, NodeReal, and others will have 11 SPs and 13 validators initially to ensure a smooth start for Greenfield.  becoming a Greenfield validator/ storage provider involves a steep learning curve, substantial investments in hardware and resources, and the need for continuous monitoring and maintenance, making it a demanding and challenging endeavor. You can read more about token economics here

Anyone is welcome to become a validator/storage provider if you are prepared to overcome the challenges and requirements associated with it. It can be a rewarding experience for those who are committed to supporting the BNB Chain network and have the necessary technical skills and resources. The detailed guidelines for mainnet are listed here and here
