Session introduction
○ Formal content ○
BNB GREENFIELD mainnet is online
Q1: What is the main purpose of Greenfield?
The main purpose of Greenfield is to build a storage-oriented blockchain that interacts with a decentralized storage provider (SP) network. This not only allows users to upload and download materials at high speeds, but most importantly establishes a new Web3 data native programmable platform to promote the Web3 data economy (tokenization) and intelligent innovative applications around Web3 data.
This new Web3 infrastructure allows ordinary people to fully grasp, control and trade their data, and everything will be more transparent. In an era where blockchain technology has transformed the financial sector and launched NFT/digital collectibles, there is still a lot of room for innovation in the field of data.
Specifically, Greenfield’s goals include the following:
1). Use an encrypted wallet to provide users with a secure login method that is compatible with Ethereum wallets.
2). Allow users to easily create, read, share and run data as cheaply as using mainstream cloud storage services.
3). Ensure users have full ownership of their data and that they can control who can access and use it.
4). Help users manage their data assets through smart contracts to create more financial value and benefits.
5). Provide users with programmability of their data assets through smart contracts and intelligent management of their assets through code control.
Greenfield encourages users to take control of their own data, and also encourages the community to work together to innovate business models. Our ultimate goal is to allow users to manage and profit from data in a more free and transparent way in the Web3 era.
Q2: What is the core philosophy of BNB Greenfield?
The core concept of BNB Greenfield is to use decentralized technology to change the landscape of the data economy. It aims to promote decentralized Web3 data management and access, and provide more reliable and cost-effective solutions for data exchange/transaction. The BNB Greenfield network has the following features:
1) High performance: Greenfield exceeds industry standards for uplink and downlink bandwidth, leveraging its novel SP architecture to deliver fast upload and download speeds. After multiple rounds of stress tests on the test network, the uplink bandwidth reached 30M/s, the downlink bandwidth reached 300M/s, and each SP can upload 30 files/s.
2) Built-in access control: Users upload data and set unique access and usage permissions, then SP stores the data off-chain and backs it up.
3) Cross-chain programmability: The cross-chain programmability of Greenfield blockchain also means that BNB Chain users can create their own data products and services.
4) Data commoditization and trading: Through Greenfield, users can establish a data market where they can freely create, list, trade and sell their data.
Q3: How does Greenfield ensure data security and privacy?
Greenfield provides built-in access control functionality, allowing users to set unique access and usage rights when uploading data. In addition, data is stored off-chain through extensive redundancy and backup, increasing the durability and security of the data.
In the world of Web2, users of cloud services have very limited ownership and control over their data. They rely on cloud service providers such as AWS/Alibaba Cloud for their infrastructure and product policies.
Existing distributed storage networks (DSN) do not have a good solution in terms of data privacy and access control. Files stored on FileCoin and Arweave are publicly accessible, meaning anyone can retrieve them. Access control can only be ensured by encrypting files. It is important to note that once a file is uploaded to the Arweave network and added to the blockchain, it cannot be deleted.
BNB Greenfield introduces the concept of data ownership and access rights into DSN and enables it to be programmed through BSC smart contracts through cross-chain and potential future off-chain computing scenarios. This brings more business possibilities to the data economy.
Q4: What are the characteristics of Greenfield’s cross-chain function?
Greenfield’s cross-chain functionality enables users of BNB Chain to create their own data products and services. This means they can create data marketplaces and freely create, list, trade and sell their data.
Digital publishing has matured and is now a mature industry. E-books, games, music, long videos and short videos have become very common and widely loved by authors and readers. BNB Greenfield can help this industry in the following two ways.
1) Support grassroots digital publishing: Traditional publishing may be a bit cumbersome for amateur writers and creators. Too often, their work is considered too niche to deserve attention from traditional or online publishers. But with Greenfield and BSC, the situation is very different. Amateur authors can upload their work to Greenfield and then share it on BSC. They can sell their works on the BSC Market, and after buyers pay, the market automatically grants them access. Without going through a traditional publisher, authors can manage their own communities with just a few clicks on the dApp.
2) Data market: This is similar to the digital publishing market, but has a wider scope. Not just digital art, but various data types such as historical statistics and scientific research data. With Greenfield, the NFT-based BSC market can become the “eBay” of data, easily buying and selling various data types.
In short, BNB Greenfield has brought disruptive changes to the digital publishing industry by giving opportunities to amateur creators and opening up a diverse data market. This means more content for everyone to enjoy, while also empowering creators to distribute their work without having to go through red tape.
Q5: What are the main application cases of Greenfield?
Greenfield provides a variety of application cases, including decentralized hosting of AI data sets, knowledge economy platforms, content IP infrastructure, data management solutions, and content monetization ecosystems. These features will assist users, developers, profile managers and content creators to effectively manage and monetize.
1) AI + Web3:
1.1）NFPrompt:
NFPrompt is the AI-powered portal into 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, sponsored brands/projects enable precise and in-depth super marketing to the Web2+3 user base. By integrating with Greenfield, NFPrompt supports user-generated content and full ownership.
1.2) Glacier: Glacier is building a composable, modular and scalable L2 data network for large-scale Dapps. Glacier enables decentralized applications (DApps) to be built on decentralized databases (DDB). It provides programmable data composability driven by opBNB solutions to seamlessly work with NoSQL GlacierDB datasets based on BNB Greenfield. BNB Chain’s native smart contract ecosystem gives web3 users full confidence in data management.
2) Data market:
2.1) Codex Field: By leveraging BNB Greenfield’s decentralized infrastructure, CodexField gives developers true ownership and control of their code assets. CodexField’s code marketplace benefits not only developers, but also code consumers, creating a high-quality, mutually beneficial ecosystem.
3) Social networking and knowledge sharing:
3.1) Using BNBGreenfield data permission management, users can share their files and content with corresponding users, and relevant users can access authorized content. At the same time, combined with the sharing function and programmability of social media, the content you share can be automatically shared with users at fixed points to protect user privacy.
Q6: How does Greenfield handle the large number of online transactions?
During testing, the Greenfield network has successfully processed over 200,000 on-chain transactions and connected to 150,000 wallet addresses. This is due to BNB Greenfield’s scalable architecture, ensuring high performance and low latency even during large-scale data transfers. Our network ensures users can quickly access their data under any circumstances by decentralizing data storage, using efficient transport protocols and optimized routing algorithms.
During the test network, the development team conducted several rounds of stress testing. In these tests, upstream bandwidth reached 30 megabytes per second and downstream bandwidth reached 300 megabytes per second. Each service provider (SP) is capable of uploading 30 files per second.
Performance comparison is as follows
Q7: What is the economic model of BNB Greenfield? Will there be incentives for mining or storage?
BNB Greenfield has designed an incentive mechanism to encourage nodes to provide storage space and stay online. Users pay for their storage space and bandwidth, and nodes that provide resources to the network are compensated accordingly. Specific economic model details may be adjusted based on actual demand and network status, but overall, our goal is to build an ecosystem that is both reliable and sustainable.
There are two important roles in the Greenfield network: validator and SP
Validator is responsible for ensuring the authenticity and reliability of data on the chain, in order to obtain corresponding block rewards. On-chain data includes account balances and file metadata. Block rewards come from fees paid by users. Please refer to this document for specific costs.
https://docs.bnbchain.org/
greenfield-docs/docs/guide/core-concept/gas-fees#fee-table
Each SP is responsible for handling user requests to upload and download data. They play a key role in the network, ensuring that users can upload and download data smoothly, and verifying users' identities and permissions to maintain system security and reliability. SP's revenue comes from users paying fees for file storage and downloading data packages, which are settled through BNB. These fees are based on time of use. You can calculate the cost of storing your files on the following page
https://dcellar.io/pricing-calculator
Greenfield's SP will also share part of the fees generated by the storage service with the validator. They are encouraged to maintain the integrity of the system, thereby protecting users' data and ensuring network stability. This model helps build a trusted distributed storage ecosystem.
Q8: What is the role of BNB tokens in the BNB Greenfield system?
The BNB token plays multiple core roles in the BNB Greenfield system. It is used as fuel to power the system. In addition, BNB tokens are also used for staking, governance, gas, and as tokens for storage service fees. It is the economic backbone of the entire BNB Greenfield ecosystem.
1) BNB tokens are used for staking: BNB is used to support the security and operation of the network. The validator of the Greenfield network needs to pledge 1000BNB to qualify as a valdiator. Validators earn block rewards by packaging transactions in blocks, but may also be penalized for misconduct.
2) Pay gas and fees: BNB can be used to pay transaction gas fees on the Greenfield blockchain, including Greenfield local transactions or cross-chain transactions between Greenfield and BSC. These fees are charged when a transaction is submitted and assigned to Greenfield’s validator, depending on the transaction type. You can refer to this document for details: https://docs.bnbchain.org/
greenfield-docs/docs/guide/core-concept/gas-fees
3) Pay for file storage and download data packages: BNB can also be used to pay for object storage and download bandwidth data packages. These fees are charged based on time of use and then allocated to Greenfield's storage provider (SP) to support the storage and downloading of the data. You can calculate the cost of storing your files at https://dcellar.io/pricing-calculator
Q9: How does BNB Greenfield compare to other decentralized storage solutions?
What makes BNB Greenfield unique is its deep integration with BNB Chain. This means it can better support and serve dApps and users on BNB Chain. In addition, we focus on simplifying data storage and management to provide users with an experience that is both simple and efficient. Of course, we also pay great attention to data security and decentralization to ensure the highest level of data protection.
FileCoin/Arweave has not yet solved the problems of the data economy:
1) Performance
1.1) Delay problem:
While decentralization provides the benefits of redundancy and censorship protection, in FileCoin and Arweave it introduces high latency. Retrieving data from these two systems is slower than getting it from a centralized server. This is particularly important when data needs to be "read" frequently (e.g. for policy or operational purposes).
1.2) Network scalability:
More adoption leads to more data storage, which again affects retrieval performance. Handling increased demand is a challenge faced by every decentralized system.
2) Ownership is hard:
2.1) Immutable storage:
Taking Arweave as an example, once data is stored, it becomes immutable. This means it cannot be modified or deleted. This feature is incompatible with data exchange and raises concerns about ownership rights, particularly when deletion is required based on the right to be forgotten.
2.2) Retrieval mechanism:
The current FileCoin retrieval market is not always as fast as IPFS pinning services or traditional cloud storage, and Filecoin storage providers typically accept a minimum file size of a few GB. The Arweave network also faces bottlenecks in efficiently retrieving large files.
3) Programming:
3.1) Both FileCoin and Arweave are constantly growing and adapting to market needs. However, they do not offer comprehensive solutions and natively integrated solutions to add programmability on top of their respective decentralized storage networks. This not only slows down the development and integration process, but also creates new barriers for Web2 enterprises and Web2 developers to use Web3.
3.2) Both FileCoin and Arweave require specific programming skills that are new even to the Web3 community. This further slows down the adoption of the data economy.
Q10: How to deploy my application or website to BNB Greenfield?
BNB Greenfield provides a series of developer tools and APIs that allow dApp developers and website owners to easily deploy their content onto our decentralized storage network. We will provide detailed documentation and tutorials to guide developers on how to get started.
There are different suggestions for different developers:
1) If you have tried to build your data products and services on IPFS/Arweave. You no longer need to spend a lot of time and effort maintaining the code on FVM/FileCoin and SmartWave/Arweave. You can complete smart contract development on EVM. Greenfield's cross-chain programmability will greatly reduce the difficulty of your product development and improve product flexibility. For example, here is the data marketplace Demo

Is it possible that Greenfield will be able to store online game databases in the future for players to interact with?
After experiencing the death spiral of GameFi, in 2023 the community began to invest more resources in full-chain games - games that completely store game logic and data on the chain. This type of game relies heavily on intelligence during interaction and operation. contract to implement. If we learn from the experience of Web2, we can split the full-chain game technology architecture into four layers: infrastructure layer, middleware layer, service layer, and application layer. The infrastructure layer including data storage, cloud computing, database management, etc. will become an indispensable link, and the increasingly mature Greenfield ecosystem can well meet this link. Glacier on the Greenfield testnet is currently building a composable, modular and scalable L2 data network for large-scale Dapps. Glacier enables decentralized applications (DApps) to be built on decentralized databases (DDB). It provides programmable data composability driven by opBNB solutions to seamlessly work with NoSQL GlacierDB datasets based on BNB Greenfield.
How does Greenfield itself achieve economic benefits? In addition to entering into BSC’s existing ecosystem, is it possible to integrate with traditional industries?
BNB Greenfield has designed an incentive mechanism to encourage nodes to provide storage space and stay online. Users pay for their storage space and bandwidth, and nodes that provide resources to the network are compensated accordingly. BNBChain itself will also operate some SPs and Validators. In addition, with the development of the ecosystem, community users will contribute more valuable applications, which will accordingly bring more economic benefits to the community. As one of the largest public chains in DAU, BSC will still be one of Greenfield's largest C-side traffic portals. At the same time, we are also actively seeking comprehensive cooperation with Alicloud and AWS to link Web2 and Web3 to gain more possibilities, especially in terms of AI, which makes the generation of data and knowledge more efficient. Web3 can help solve many key issues in AI, such as data privacy protection, AI IP protection, etc. https://nodereal.io/blog/en/exploring-the-crossover-of-artificial-intelligence-and-web3/
How is the current development progress of the project? Can you describe the current progress in detail?
Mainnet launched on October 17, 2023. After five months of development from test net to mainnet, Greenfield already has access control capabilities, excellent upload and download speeds, cross-chain programming, and a relatively complete infra and tooling foundation.
In the future, Greenfield will focus more on scenarios (such as AI + Web3, IP market, full-chain games, etc.), focus on continuously improving performance, reducing usage costs, exploring being a modular DA layer, and seamlessly connecting with opBNB and other L2s, etc. . For more information, please follow our blog: https://www.bnbchain.org/en/blog/greenfield-from-testnet-to-mainnet
What is the difference with OP-BNB?
First of all, opBNB is the first L2 solution based on OP Stack launched by the BNBChain ecosystem. It solves the scalability and security issues of the chain, and serves high-frequency transactions and low Gas user scenarios, and can fit into high-frequency DeFi transaction scenarios. , GameFi and SocialFi’s L2 solutions. And Greenfield is building a comprehensive infrastructure (including high performance, built-in access control (privacy), EVM-compliant programmability (developer-friendly) and seamless payments) to inspire the continued development of the Web3 data economy. Greenfield will focus on empowering creators, developers and projects to build, deploy and monetize their data and intellectual property (including code, publications, novels, music, videos, etc.). At the same time, opBNB and Greenfield are also continuing to integrate and cooperate with each other, such as Greenfield's ability to serve as the DA layer of opBNB. The deep integration of these two projects will promote BNBChain to become an all-in-one ecosystem for developers/consumers, promoting The BNBChain ecosystem continues to improve in efficiency and performance.
What other ideas do you have for the future of Greenfield?
Greenfield provides a variety of application cases, including decentralized hosting of AI data sets, knowledge economy platforms, content IP infrastructure, data management solutions, and content monetization ecosystems. These features will assist users, developers, profile managers and content creators to effectively manage and monetize. In addition, Greenfield will focus on empowering creators, developers and projects to build, deploy and monetize their data and intellectual property (including code, publications, novels, music, videos, etc.). At the same time, opBNB and Greenfield are also continuing to integrate and cooperate with each other.
How will Greenfield create a sustainable Web3 ecosystem?
First of all, Greenfield will continue to deeply integrate with opBNB and BNBChain, providing complete infra and toolings to help developers continue to realize new ideas; secondly, it will explore being a modular DA layer, and seamlessly connect with opBNB and other L2, etc. In the long term, it will Break out of the BNBChain ecosystem and commit to serving the larger ecosystem
