Type your name and press the button. The node signs it into a real transaction, drops that transaction into a fresh block, and chains the block onto everything that came before it. Your name becomes part of the fingerprint that every future block commits to. Nobody has a delete button, and that includes me.

Each frame below is a block: a bundle of what happened at one moment, stamped with a fingerprint of everything before it. Change a single byte in any past block and every fingerprint to its right stops matching. That is the whole trick, and it is the only reason your name is safe here.
The hashes on this page are real SHA-256 fingerprints computed by the jOhNCHAIN node running behind it. A block's own hash is read off the next block's prev_hash, because a child's commitment is what a hash is for; the newest block has no child yet, so the node reports it directly. The state root is a single commitment to every balance, every nonce, and every entry of the evolving S-box at that height. See what is evolving inside → Hand-written HTML. No frameworks, no build step, no trackers, one file. Same as it ever was.
