BNB Greenfield vs Walrus

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.

Walrus is a verifiable data platform for storing and managing data across apps, providers, and agents. Its decentralized storage protocol is coordinated onchain through Sui. Storage costs $0.023/GB/month, paid in WAL, with SUI used for transaction gas; stored data expires when its paid duration ends. Walrus Memory is intended to give AI agents persistent, portable memory across apps and sessions. It supports semantic remember and recall, automatic fact extraction, and generated answers grounded in stored memories. Listed integrations include native MCP support, plugins for OpenClaw and NemoClaw, and compatibility with major LLMs. Developers get TypeScript and Python SDKs, a relayer, smart contract, indexer, and dashboard. Memories are encrypted before storage and decrypted only for an authorized signed request; Sui contracts enforce ownership and programmable access, including scoped delegation. The separate Walrus Console is in a closed, invite-only Mainnet beta, with each space limited to 5 GB and five folders and uploads capped at 100 MiB. Walrus Memory has a launch-period free plan, with usage limits that may change.
