Arweave vs Crust Network

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.
