Filecoin vs Walrus

Filecoin is a decentralized storage network where users pay independent providers to store data and retrieve it later. Proof of Replication verifies that a provider holds a distinct copy, while Proof of Spacetime verifies storage over time. Listed uses include Web3 apps, AI datasets, backups, archives, cultural records, and scientific datasets. The Filecoin Virtual Machine adds smart contracts for logic, automation, and applications built around storage. Filecoin Onchain Cloud lists verifiable storage and retrieval, programmable payments, and a Synapse TypeScript SDK. Integrations listed through other services include Snowflake and Apache Iceberg via Akave, and Nextcloud via CIDgravity. Plans vary: Filecoin Onchain Cloud is $2.50 a month, billed from $2.50 / TB / month with a two-copy minimum; Fil One is $4.99 a month, billed from $4.99 / TB / month. CIDgravity is $5 a month, billed from $5 / TB / month, with the first 2 GiB free. Lighthouse is $12 a month, billed from $12 / 500 GB / month, with the first 5 GB free. Fil One has a free trial. Lotus node installation supports Linux and macOS; Windows is not supported for that installation.

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.
