0G Storage vs Walrus

0G Storage is a distributed storage layer for onchain applications, including AI agents, DePIN, and gaming. It provides an append-only Log Layer for unstructured data and a mutable Key-Value Layer for structured data. The product page describes 50 Gbps throughput for the Log Layer, millisecond-level access to structured and unstructured data, and sub-second access for the KV Layer. Cryptographic proofs, erasure coding, sharding, and Proof of Random Access challenges support integrity and availability. Uploads are committed on-chain as Merkle roots, while mutable states preserve immutable history. Listed workloads include datasets, media, AI model weights, sensor logs, vector embeddings, user state, and metadata. Developers can use TypeScript or Go SDKs, a CLI, or a web upload tool. It integrates with blockchains, rollups, VMs, hybrid stacks, and Web2 applications. Pricing starts at $11/mo, with API, Linux, macOS, self-hosted, and web access.

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.
