BNB Greenfield

What BNB Greenfield is
BNB Greenfield is a decentralized storage and blockchain storage system centered on data ownership and the data economy. Developers can associate permissions and management logic with exchangeable assets and smart contract programs, managing data and permissions through contracts on BSC and opBNB. Ethereum-compatible addresses can create and manage data and token assets. The service describes multi-copy decentralized storage and says uploaded data can be accessed before block completion. Its developer resources include APIs, Go and JavaScript SDK guides, tutorials, a command line tool, and an explorer; similar SDK practices and metadata handling are described for migration from Web2 storage. Costs include validator gas fees and storage-provider charges, which use streaming payments. Download quotas are time-based, and additional data packages may be needed after exceeding them. If funds run out, downloads may be downgraded and providers may eventually clear data. The repository states that code and security audits were not fully complete and were not ready for production use at the time of that statement. Storage and download plans each list free with per-GB billing and free quotas that vary by provider.
Who it suits
It suits developers building storage workflows around smart contracts, data permissions, and token assets, as well as validators and storage providers invited to join the ecosystem. Teams considering production use should account for the repository's stated code and audit status, payment model, quota, and retention conditions.
What it does well
- Manage data and permissions through BSC and opBNB contracts
- Ethereum-compatible addresses can manage data and token assets
- Provides APIs, SDK guides, tutorials, CLI, and explorer
- Describes access before block completion
- Lists Web2 migration practices
What to know first
- Repository says code and security audit were incomplete
- Download quotas are time-based
- Insufficient funds can lead to data being cleared
- Storage and transaction services involve fees
Limits
Storage is billed at 0.00004005 BNB/GB/month, and the free quota varies by selected storage provider. Download service is billed at 0.00015672 BNB/GB/month, with a time-based free quota that also varies by provider; exceeding it may require an additional data package. If payment funds run out, download service may be downgraded and providers may eventually clear stored data.
