BNB Greenfield

Name Track (DeFi, AI, Infra, Gaming) Description
Mobile App for Greenfiled Infra The challenge is to develop a user-friendly iPhone/Android application that enables users to manage their data on BNB Greenfield. The primary focus of the application should be on delivering an exceptional user experience (UX) and user interface (UI), ensuring that the user journey is engaging and intuitive. The application can incorporate gamification principles such as badges and rankings to enhance user engagement, etc
The goal of the application is to provide users with a seamless and convenient way to interact with their data on BNB Greenfield. It should offer features for uploading, organizing, and accessing stored data, with an emphasis on user-friendly navigation and visually appealing design. The application should prioritize ease of use and aim to make data management tasks as effortless as possible for the users.
As part of the challenge's acceptance criteria, the final deliverable is the deployment of the developed application to the respective app markets, such as the Apple App Store and Google Play Store.
Migration tooling from other dStorge (Filecoin, Arweave, Storj) Infra The challenge is to develop a migration application for BNB Greenfield that provides a seamless solution for migrating files from various decentralized storage solutions like AWS, Filecoin, Arweave, Storj, etc. The tool should prioritize user experience (UX) and ease of use, enabling users to effortlessly transfer their files to BNB Greenfield. Integration with popular integrated development environments (IDEs) such as VSCode, Eclipse, Android Studio, Xcode, and IntelliJ IDEA should be a key focus, aligning with their design principles.
The migration tool should offer a user-friendly and automatically identify the files for migration through an intuitive graphical user interface (GUI) or interactive interface, reducing the need for extensive configuration files. Users should be able to input essential details, such as private keys and file paths, directly through the GUI. It is advisable to integrate a wallet solution to eliminate the need for hardcoding private keys altogether, enhancing security and user experience.
The tool should be designed to be extendable, allowing for the easy addition of more networks as sources for migration. This flexibility ensures that the tool can adapt to evolving storage solutions and cater to the needs of both web2 and web3 developers. As part of the acceptance criteria for the challenge, the application should be deployed to the extension marketplace, supporting at least two networks—one centralized and one decentralized—to showcase its capabilities in facilitating smooth file migration for various development environments.
NFT minting tooling Infra The challenge is to develop programmability features for BNB Greenfield's decentralized storage ecosystem. This involves mirroring the existing resources such as buckets, objects, and groups on the BNB Smart Chain (BSC) as non-fungible tokens (NFTs) conforming to the ERC-721 standard. By mirroring these resources on the BSC, they can be managed and manipulated through smart contracts, providing greater programmability and control over data storage on Greenfield.
The integration between Greenfield Blockchain and BSC enables seamless synchronization of data and operations. Any changes made to the decentralized application on BSC will directly impact the storage format, access permissions, and other aspects of the data on Greenfield. This integration enhances flexibility, accessibility, and streamlines the data management process within the decentralized storage ecosystem.
Decentralised AI Training AI The challenge at hand is to decentralize the AI training process, which is currently limited to a few corporations or high-profile startups that can afford the massive computational resources required. The objective is to create a framework within BNB Greenfield that allows AI models to be trained collaboratively and securely, fostering the sharing of training data. The concept revolves around sharing training batches or splitting the training data, demonstrating feasibility using small-sized datasets and frameworks like Torch or TensorFlow.
The proposed solution aims to ensure fairness and incentivization by recording all contributing trainers as part of the model's metadata. When a user wants to access a trained model, a fee will be charged, which will be split among the trainers based on factors like the amount of training data processed or the GPU cycles utilized. This approach promotes collaboration while providing a decentralized alternative for AI training that is accessible to a broader range of participants.
To prevent fraud and maintain the integrity of the training process, the solution should incorporate a verification mechanism. This process will confirm that the training was indeed performed by the designated trainers, safeguarding against malicious activities. By addressing these challenges and implementing a decentralized AI training solution within BNB Greenfield, the platform can democratize access to AI technologies and foster a collaborative environment for the development and sharing of trained models.
Decentralized SocialFi AI BNB Greenfield can be used to store access social information, member-only newsletters, trading strategies, scientific papers and journals. They can store (as proofs) the results of reproducible experiments and provide incentives for content creators to upload new findings and strategies over time.
Can the peer review process be made more fair (perhaps through quadratic voting)?
How can experimental code be made reproducible? Often these are written as one-off scripts and can be hard to recreate, even for famous publications.
We also need to enable massive scale data science on the data collected on these papers. We can make metadata analysis really easy because the data collected on Greenfield and can be analyzed and imputed in a straightforward manner.
Trustless Notary Infra Notaries play a crucial role in establishing social trust and verifying the authenticity of clients, thereby preventing malicious actors from engaging in fraudulent activities. However, the advent of smart contracts enables the creation of permissionless notaries, which render it economically unfeasible to attempt any form of malicious activity such as sybil attacks.
An example of a trustless notary could resemble an on-chain auction, where all participants, including clients and storage providers, are required to commit a certain amount of collateral as a prerequisite for participation. By conducting the auction through a smart contract, anyone can verify that the winners were determined through a transparent process. The utilization of economic collateral from both clients and storage providers can establish a slashing mechanism that discourages malicious actors.
In return for overseeing the auction, the notary maintainer might receive compensation in various forms. This could include a portion of fees for facilitating the completion of the deals, collecting a fee based on the locked collateral (such as a fraction of the yield if staked BNB is used as collateral), or a combination of both options.
Blockchain of Things Infra IoT devices play a crucial role in monitoring and measuring the temperature, humidity, and CO2 levels in diverse environments. However, the process of collecting and uploading this data to a public repository for further utilization poses significant difficulties. Moreover, the data quickly accumulates, making it challenging to efficiently store and process in a centralised way. In order to enhance security and ensure greater availability and reliability, decentralization is a key approach for IoT devices. By adopting a decentralized system, the risks of security breaches can be mitigated while also improving the overall performance and dependability of the devices. As part of this endeavor, you are to construct and demonstrate an end-to-end system that seamlessly connects an IoT device (such as a Raspberry Pi) to a queue pipeline, facilitating the smooth transfer and storage of data onto Greenfield.

opBNB

Name Track (DeFi, AI, Infra, Gaming) Description
Rust and Erigon opBNB Client Infra Supporting multiple client options is a key to make the ecosystem healthy, especially for opBNB. It will benefit the opBNB sequencer ecosystem.Currently the client of opBNB is based on the op-geth, and it is necessary to cover other major clients, like clients in Rust Reth, or Erigon.
Please note we do not limit the implementation of the client, Reth and Erigon are just two examples.

https://github.com/node-real/bsc-erigon.
Interoperability tools between Greenfield and opBNB Infra The BNB Chain ecosystem allows different chains to communicate with each other natively. BSC and Greenfield use a relayer system to mirror objects across the chains. We want to extend this feature to opBNB and Greenfield as well. This will enable smooth cross-chain interactions between opBNB and Greenfield. To ensure the security and integrity of the cross-chain communication, we have implemented a new relayer system between BSC and Greenfield. Please refer to the Greenfield design document and SDK for more details. For opBNB, we assume a similar mechanism should be in place.
We want the follow two key features are to be implemented:
1. The solution supports transferring assets from opBNB to Greenfield, including BNB and other BEP 20 tokens.
2. The objects created on Greenfield can be mirrored to opBNB and vice-versa.
