Carbide Network vs Walrus

Carbide Network is a distributed storage service that links users’ files with independent providers. Its personal offering covers photos, documents and backups, with photo and video auto-sync, an encrypted vault, expiring share links and up to 10x redundancy. Files are encrypted on the user’s device with AES-256-GCM; the service describes its design as zero-knowledge. Encrypted chunks are spread among providers, and users choose between 1 and 10 copies. Users manage their private encryption keys, and Carbide says lost keys cannot be recovered. Business tools include role-based team workspaces, audit logs, retention policies and geographic redundancy across 30+ regions. Developers get API-first, S3-compatible storage, a versioned API and a Swift SDK. The service lists macOS, Windows, iOS and Android apps, as well as API access. Personal storage is billed at $0.002/GB. The network is provided without warranties, and performance depends on the combined behavior of independent participants.

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.
