In their own words
BNB Greenfield
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.
Sia
Sia offers encrypted, decentralized cloud storage through a consumer app and tools for developers building storage into applications. Files are encrypted on the user’s device before upload, and Sia says nobody else can read them. The app describes files as redundantly held across independent hosts worldwide, with parallel downloads from multiple hosts. Sia describes its peer-to-peer network as having no central access point or single point of failure. Consumer plans list 50 GB on Free, 500 GB for $7.99 a month on Plus, 5 TB for $14.99 a month on Pro, and 10 TB for $19.99 a month on Unlimited; Unlimited lists 4.99 USD/TB-mo over its included capacity. Separately, the network page lists median prices of $3.53/TB/month for storage at 3X redundancy, $0.03/TB for upload, and $2.25/TB for download. Developers can use storage SDKs for Rust, Go, Python, and JavaScript, or the S3-compatible s3d gateway with rclone, Cyberduck, Nextcloud, and Duplicati. The SDK can connect to an indexer hosted by the user.
