Arweave vs Peergos

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.

Peergos is a storage, sharing, and sync service that describes itself as post-quantum end-to-end encrypted. Files are encrypted on the user's device, and the maker says account keys never leave it. It says the server cannot see file names, sizes, folder structure, modification times, file types, contacts, or sharing relationships. Folder sync works in both directions, uploading changed chunks; users can configure it not to propagate deletions so sync can act as backup. Sharing links can expire, require a password, limit uses, or allow writing back. Built-in tools include calendar, document and spreadsheet editors, PDF viewing and editing, media playback, an image gallery, task board, Markdown browser, and wiki. Desktop apps support WebDAV and CalDAV/CardDAV, and Android syncs calendars and contacts with phone apps. Drive mounting is available on Windows, Linux, and Android, but not macOS. The maker says the software and server are open source and that audits by Radically Open Security and Cure53 are published in full. Self-hosting is free; paid plans list storage from 200 GB to 3000 GB.
