Changed the definition of "anchor_proof", "check_proof" and "search_names"
Anchor a SHA-256 hash on the Doichain asproofathattamper-evidentthetimestampdocument(proofexistsofnowexistence,(namepoe/<sha256>).Free for users, limited per IP address and day (see get_anchoring_quota). Confirms with the nextblock,usually within 10 minutes, then check_proof returns block height and time. If the hash is alreadyanchoredanchored or pending, the existing proof is returned instead of creating a second one. If an earlier proof of the hash has expired, it stays valid and is returned with expired true. Nothing is registered unless reanchor_expired is true. Only the hash and the optionalnote and file name become public, never the document itself. The operator of this server pays for the name and holds it. The proof shows that a document with this hash existed no later than the block time, not who submitted it.
