Arweave's blockchain-based public archive, designed for permanent data storage, raises concerns about illegal content. Its decentralized "permaweb" ensures data immutability, making removal nearly impossible. While miners can filter content via policies, the lack of mandatory censorship risks hosting illegal material, like copyrighted or illicit media. Data is public by default unless encrypted, but encryption keys can be shared, complicating privacy. Arweave's partnerships, like with the Internet Archive, highlight its archival potential, but the absence of centralized control challenges legal oversight. Critics argue this enables misuse, while supporters emphasize its censorship-resistant benefits for free speech. Balancing freedom and responsibility remains a key issue, with no clear solution for preventing illegal content without compromising Arweave’s core principles.
