Spec score 8.0 #7 of 25 in Decentralized Storage Services

What it is

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.
