Field notes
Visitors can register a next step, anchor a batch, then try editing, deleting, or inserting a backdated approval before auditing. The page says each ten-minute batch is folded into a 32-byte Merkle root; its demo feed shows checkpoint identifiers, record counts, and Bitcoin block numbers. It also estimates 960 bytes to prove one record among a billion, while labeling the displayed feed as simulated.
