BNB Greenfield vs Datum Storage

BNB Greenfield is a decentralized storage and blockchain storage system focused on data ownership and the data economy. It connects data permissions and management logic with exchangeable assets and smart-contract programs. Developers can manage data and permissions through contracts on BSC and opBNB, while Ethereum-compatible addresses can create and manage data and token assets. The system describes multi-copy decentralized storage, with uploaded data available without waiting for block completion. Similar SDK coding practices and metadata management approaches are intended to support migration from Web2 storage. Developer resources include APIs, Go and JavaScript SDK guides, tutorials, a command-line tool, and an explorer. Highlighted ecosystem projects involve 4EVERLAND web hosting, Glacier DeVector, and NFPrompt NFT storage. Users pay validator gas fees for transactions and storage providers for storage, with storage charges using streaming payments. Download quotas are time-based; extra data packages may be needed after exceeding them. If funds run out, downloads may be downgraded and providers may eventually clear data. Storage and download-quota plans list free with stated per-GB billing.

Datum Storage is decentralized cloud storage running on the Datum Network, with access listed for Android, iOS, and API use. Datum Drive adds a virtual hard disk to a computer that behaves like a folder. The product says files are end-to-end encrypted and that users hold the key. Storage accounts attach to a Datum Identity, whose creation requires email and phone verification. For software connections, the service supports the Amazon S3 API format and custom S3 endpoints. After account creation, users receive a URL plus a key and secret corresponding to S3 access credentials; Datum recommends Signature Version 4 if a backup application offers a choice. Arq Backup for Mac and Windows is listed as tested. Duplicati, Duplicity, and Duplicacy are named as S3-compatible applications but have not been tested by Datum. The Datum ID app is listed in the App Store and Google Play for sign-up and credential and usage management, though the mobile workflow is described as coming soon. A free plan provides one terabyte for the first year. Additional storage is listed at US$3.99 per terabyte per month and is also described as coming soon.
