Arweave vs Datum Storage

Arweave is a decentralized network for permanent information storage in an open ledger, with a permanent web built on that storage. Its stated uses include preserving important data and hosting decentralized web apps; people can upload files or create a homepage on the permaweb. Transaction fees are set dynamically by the network, and the documentation recommends checking the price endpoint close to submission. The HTTP-based protocol works with existing clients such as Axios, Fetch, and Guzzle. Listed client integrations cover Go, PHP, Scala, Java, C#, JavaScript, TypeScript, and NodeJS. Node software can be installed from pre-built binaries or built from source; documented roles include solo, coordinated, and pool mining, VDF server, and validator. Arweave describes content as timestamped and tamper-proof through the blockweave, with data integrity checks using transaction data in block hashes and recall blocks. Once one or more miners store data, there is no guaranteed way to delete it, and the policy advises against storing cleartext personal or confidential information. Wallets store private keys; lost key files cannot be recovered by wallet providers.

Datum Storage is decentralized cloud storage running on the Datum Network, with access listed for Android, iOS, and API use. Datum Drive adds a virtual hard disk to a computer that behaves like a folder. The product says files are end-to-end encrypted and that users hold the key. Storage accounts attach to a Datum Identity, whose creation requires email and phone verification. For software connections, the service supports the Amazon S3 API format and custom S3 endpoints. After account creation, users receive a URL plus a key and secret corresponding to S3 access credentials; Datum recommends Signature Version 4 if a backup application offers a choice. Arq Backup for Mac and Windows is listed as tested. Duplicati, Duplicity, and Duplicacy are named as S3-compatible applications but have not been tested by Datum. The Datum ID app is listed in the App Store and Google Play for sign-up and credential and usage management, though the mobile workflow is described as coming soon. A free plan provides one terabyte for the first year. Additional storage is listed at US$3.99 per terabyte per month and is also described as coming soon.
