Arweave vs Storj

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.

Storj provides distributed cloud Object Storage and Object Mount for accessing cloud files as if they were local. Object Storage is described as a drop-in AWS S3 replacement, while Object Mount works with S3-compatible storage and provides POSIX access without modifying files or requiring a gateway. Existing buckets can be mounted without migration. Storj encrypts data and metadata end-to-end, at rest, and in transit by default. Objects are split across tens of thousands of storage nodes, with tiers designed for 11 nines of durability. S3-compatible object lock and versioning support immutability and protection from accidental deletion. Listed integrations include Amove, Veeam, TrueNAS, Splunk, LucidLink, FileZilla, and Cyberduck. Customers use it for backup and recovery, media workflows, AI, and scientific work. Standard pricing is $7 a month per TB for storage, with 7.00 USD per TB egress and a 5.00 USD minimum monthly fee. A 30-day free trial is available; there is no free plan.
