Field notes
The date picker maps a chosen moment to the first block mined afterward in UTC, and the preview is shown before payment. The five layouts range from a decoded block with its header and figures to an 8 × 8 hash grid; the site says it waits for six confirmations before finalizing the selection. A bitcoin-cli example and a check command printed on each poster are presented as ways to verify the block data.
