0G Storage vs Stratos

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.

Stratos is a distributed infrastructure network offering computation, storage, and network traffic resources for blockchain applications. Its four core modules are blockchain, decentralized storage, decentralized databases, and decentralized computing. The documentation describes it as a platform for blockchain and Dapp developers to deploy, store, and execute code and data. The network uses Proof-of-Stake for its value layer, Proof-of-Traffic for resources, and Proof-of-Authority for meta-services; Proof-of-Traffic rewards participants based on network traffic contributions. Stratos IPFS, or SPFS, is an IPFS cluster for persistent storage. Its guide covers uploading, fetching, pinning, unpinning, and sharing files through API and WebUI instructions. The private access token is free with usage limits that can be expanded through a subscription. Gateway requests require an access token and face tier-based rate and traffic limits. Stratos lists Android, iOS, Linux, macOS, web, Windows, API, and self-hosted access, and is headquartered in Canada.
