Verify a listing anchor

Confirm that a published Opportunity's content matches the SHA-256 hash recorded for its version, and that the hash is anchored on the SOST blockchain. This proves content integrity and timestamp — not ownership, legality or asset value.

What the hash proves

GeaSpirit connects owners and buyers. It never custodies funds, transfers title, or tokenizes a mine. Anchoring records a one-way hash + timestamp on SOST so a published version cannot be silently altered; it does not validate the truth of the seller-provided claims.
