A Bitcoin Anchor. A signed certificate binding the buyer's sha256 digest in its attests field, plus a stable proof URL serving the OpenTimestamps proof bytes — pending on purchase, upgrading automatically to a Bitcoin-confirmed proof verifiable with the standard ots tool against block headers alone. Instant; one digest, one submission, nothing recurs. Full listing: https://scvd.store/menu/bitcoin_anchor. MCP tool: buy_bitcoin_anchor.
