Sia vs Stratos

Sia offers encrypted, decentralized cloud storage through a consumer app and tools for developers building storage into applications. Files are encrypted on the user’s device before upload, and Sia says nobody else can read them. The app describes files as redundantly held across independent hosts worldwide, with parallel downloads from multiple hosts. Sia describes its peer-to-peer network as having no central access point or single point of failure. Consumer plans list 50 GB on Free, 500 GB for $7.99 a month on Plus, 5 TB for $14.99 a month on Pro, and 10 TB for $19.99 a month on Unlimited; Unlimited lists 4.99 USD/TB-mo over its included capacity. Separately, the network page lists median prices of $3.53/TB/month for storage at 3X redundancy, $0.03/TB for upload, and $2.25/TB for download. Developers can use storage SDKs for Rust, Go, Python, and JavaScript, or the S3-compatible s3d gateway with rclone, Cyberduck, Nextcloud, and Duplicati. The SDK can connect to an indexer hosted by the user.

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.
