What anchoring proves

A Bitcoin anchor might prove that a particular fingerprint existed no later than a certain time. It does not, by itself, prove authorship, accuracy, lawful possession, contractual assent, or the truth of the underlying document.

⚠ Arweave Permanence Warning

Professional and Legal tiers upload the full document text to Arweave — a permanent, public, decentralized network. This record cannot be deleted by anyone, including ICPO X. Do not submit classified, illegally obtained, or content you do not have the right to publish. If your document is sensitive, use the Personal tier — only the hash is anchored, no text is stored.
